Protect Yourself and Your Home from Contractor Rip-offs, Scams and Shoddy Work!

As winter comes to a welcome end and we enter the spring season, homeowners inevitably will be besieged by offers, promotions and come-ons from all kinds of home improvement contractors and installers – plumbing, air conditioning, doors, windows, remodelers, landscapers -- you name it. Most will be legit...but some won't be.

Unfortunately, fraudulent contractors are extremely common in the home improvement industry…and they really seem to come out of the woodwork around this time of year. Because this area is so specialized and intimidating to many homeowners, it is easy to get taken advantage of by a disreputable “professional.”

Whether you are looking for a home improvement contractor to perform routine repairs, install equipment or perform major reconstruction and remodeling, here are a few simple tips to ensure that your home improvement contractor or installer is on the up and up.


Get It In Writing
Make sure to thoroughly read and understand the written contract for your home improvement project before you sign. Discuss your questions and get clarification. If you are not given an estimate and a contract in writing, or if your contractor is unwilling to explain things to you clearly, hire someone else. If you don’t understand a contract, don’t sign it; you could obligate yourself to repairs that you are not prepared to pay for. And don’t give any oral commitments to any work; as Yogi Berra once said, “An oral contract ain’t worth the paper it’s written on!”


Cheaper is Not Always Better
When it comes to home improvements, you almost always get what you pay for. Be wary of contractors that promise things that sound too good to be true. If your instincts tell you something strange is is up, you are probably right. Cheap contractors usually use cheap materials, sell cheap equipment and employ cheap, inexperienced, low-quality labor. And that can cost you a lot more in the long run -- both in operation costs and in future repairs.

Fraudulent contractors often try to scare homeowners with news of urgent or emergency repairs…or fantastic deals that you must act upon immediately. Do not let anyone pressure you into costly repairs on the spot; seek a second or third opinion to be sure. Always shop around and get multiple estimates. Focus on getting the best value; not the best price.


Check Credentials
Is your contractor properly licensed? Can he get all the permits to legally perform your home improvement or repair? Does he have a favorable rating from the Better Business Bureau? Does he belong to professional and industry trade organizations? Does he follow the industry’s best practices? Reputable contractors can answer yes to all these questions.


Get a Referral
Word of mouth is crucial in hiring a good contractor, but you have to be sure your referral is coming from a reputable source. Never base your decision on the word of a solicitor or stranger. Instead, ask friends, family members and neighbors, or consult a referral service that provides the names and contact information for qualified, pre-screened professionals in your area. Do not just go for the cheapest price estimate—take the time to get a solid referral; you could save thousands, especially if that amazing deal offered by the door-to-door salesman turns out to be a fraud. The best home improvement contractors have been in the business for some years and have a track record of customer satisfaction.


Read Home Improvement Contractor Reviews
There are plenty of websites that offer unbiased customer reviews of local businesses and contractors – among them Yelp, Insider Pages, Angie’s List, Local.com – as well as business directory sites (Yellowpages.com etc.) and search engines like Google, Yahoo and Bing. Take the time to go to these sites and check out reviews. Click Here to View a List of Customer Review Sites!


Beware of “Travelers”
“Travelers” are door-to-door solicitors that come knocking in hopes of gaining your trust and your business; this is one of the most common contractor frauds. These scam artists will talk fast, promising steep discounts on everything from roofing to bathroom remodeling. They will often cite their exclusive access to overstock building supplies as the reason for their great deals. The best way to protect yourself is to politely decline the sales pitch from the start, but you can also check the yellow pages for the name and number of the contractor at your door. If you cannot find a listing, tell him to hit the bricks.


Never Pay Up Front
No reputable contractor or installer will ever ask for payment until after the work is completed to your satisfaction, and will never require cash payment. If your contractor asks for payment up front or insists on doing a cash-only business, find a new contractor.


Do Not Get Your Own Building Permits
Another common tactic employed by fraudulent contractors is to request that you secure any necessary building permits yourself. A good contractor will do this for you — that is why you are paying him to do the work.


If You Are a Victim of a Fraudulent Contractor...
If you think you have been a victim of a fraudulent contractor, take immediate action to fix the situation. Consult a lawyer to find out if you have any legal recourse and report the incident to your local Chamber of Commerce and the Better Business Bureau. You may also need to involve local law enforcement if you believe a crime such as larceny or identity theft has been committed.

See Areas Where You Can Improve Your Energy Efficiency...and Slash Your Utility Bills!

For many homeowners feeling the economic pinch, any unnecessary home spending is to be avoided at all costs. If you fall into this category, a home energy audit can be a great way to show you if you are using energy efficiently in heating, cooling, lighting and powering your home...and show you where you may be wasting valuable energy dollars.

According to industry research, a home energy audit can reveal savings as much as 30 percent off your monthly utility bills. With utility prices expected to SKYROCKET in the coming months and years, those savings can be ENORMOUS.


How Home Energy Audits Work
A professional home energy auditor will come to your home and examine your property. He or she will look over your energy bills and analyze your energy usage. The enegy auditor will also inspect your home floor to roof -- including your heating and cooling system -- and do a number of special tests to see if energy is being consumed efficiently or wasted.

Two tests that any reputable home energy auditor will perform are the blower door test and a thermographic scan. The blower door test helps identify leaks and drafts around doors and windows, while the thermographic scan finds areas where you home is letting in cold or losing heat.

When all this data is compiled, the home energy auditor will create a detailed plan of ways you can improve the energy efficiency of your home. Some of the most common suggestions include upgrading appliances, increasing insulation, and installing weather-stripping or a programmable thermostat.


How Much do Home Energy Audits Cost?
A residential home energy audit will likely cost several hundred dollars, but you may have to pay much more than that to implement all the auditor’s suggestions, especially if you live in an older home. If your home is newer or you’ve recently updated your major appliances, you’ll spend less to get the most energy efficient features.

A home energy audit is completely useless if you don’t follow the auditor’s suggestions, but the good part is that you’ll get a detailed plan that you can follow as time and budget allow. You have the freedom to make changes little by little, shop around for deals, or wait for sales and rebate programs to kick in. There are usually several small changes you can make on your own for very little money, too, while some many need to be reserved for professionals. Remember, though, that even small home improvements can translate into pretty significant energy savings.


Is a Home Energy Audit Right for You?
Nearly every residential property can be made more energy efficient in some way. However, if your home is less than 10 years old, was designed to be energy efficient, or is a certified green home there’s probably not much an auditor will be able to tell you that isn’t already in place on your property. But if your home is decades old, a fixer-upper, hasn’t been updated with a new HVAC system in more than 20 years, or if it seems like your monthly utility bills just keep getting higher and higher, an energy audit could make a real difference for your peace of mind and your pocketbook.

In 2011, Delaware residents can take part in a new program called Energize Delaware. Under this program, Delaware homeowners can qualify for cash rebates up to $8,250 in eligible home improvements ranging from sealing air leaks to adding installation to upgrading or replacing heating and cooling systems. To qualify, you must be a registered owner of a detached, single-family residence, you must received a home energy audit and install qualified Energy Star equipment. Contact Horizon Services for more information on this program.

Clean Furnace Filters Deliver Better Indoor Air Quality and Energy Efficiency!

It’s winter and most of us have already begun to feel the effects of poor indoor air quality: dry skin, dry sinuses, stale air, etc. The average person inhales about 32,000 pints of air in a single day. Every one of those pints contains billions and billions of tiny particles of dust, pollen, dirt, and other microscopic debris. In fact, according to the U.S. Environmental Protection Agency, indoor air can be up to five times more polluted than outdoor air. Yuck!

Spending lots of time inside during the cold winter months can really do a number on your respiratory system, but there is a way to significantly improve the quality of the air inside your home. It is simple, inexpensive, and really effective. So what is it? Clean or change your furnace air filter!

In order to create the healthiest indoor environment possible, you have to keep the air clean. The best way to accomplish this is to select a furnace air filter that meets the needs of you and your family. Sounds simple, right? Unfortunately, the furnace air filter is a frequently overlooked source of poor indoor air quality, especially during the winter when heating systems run almost constantly.

As air passes through your home’s heating system, the furnace air filter traps dust and other particles and prevents them from entering your home. After several months, most furnace filters become so dirty that they can no longer effectively remove these pollutants from the air. What’s more, a dirty furnace air filter prevents your heating system from working at its peak so you could see an increase in your utility bills. Cleaning or changing the furnace filter regularly will not only improve the air inside your home, but it will also help you save money.

There are many different kinds of furnace air filters available. The key to choosing the right furnace filter is to decide which best suits your needs and your particular system. Each type of furnace filter has a different efficiency rating, different strengths and weaknesses, and different features that make them desirable for certain customers.

Generally, furnace air filters fall into one of several categories:

• Electrostatic furnace filters: Use an electric charge to attract particles; are washable and reusable
• Media furnace filters: Most frequently used in commercial applications; trap particles in thick layers of disposable material and need to be changed less frequently than other types
• Pleated furnace filters: Most common type; large surface area traps particles before they reach system interior
• HEPA furnace filters: Capture 99.9% of particles; good for allergy sufferers or environments where good air quality is essential (i.e. hospitals, nursing homes, laboratories, etc.)
• Activated carbon furnace filters: Good for removing unpleasant odors from air (ex. cigarette smoke, gases, chemical smells, cooking odors, etc.)
• Fiberglass furnace filters: Durable; sometimes coated with special adhesive to trap dust and dirt particles

Improving your indoor air quality is not the only reason to replace your furnace air filter. Dirty furnace filters are one of the primary causes of furnace breakdowns and high heating costs. The more dust and debris that accumulates on your furnace filter, the harder your furnace has to work. Your furnace air filter should be changed every three months to maintain optimum performance. Always be sure to select the right size and type of filter for your heating system. Your Horizon Services Heating Technician can advise you on the best furnace filter for your system.

Put an End to that Rattle and Hum!

You love your home’s central heating and air conditioning, but you hate all the noise it makes. Rattling, blowing, ticking, creaking, and a host of other noises coming from your ductwork can turn a fantastic convenience into a real nuisance in the time it takes to crank up the thermostat. Here are a few tips that can help turn down the volume on a noisy HVAC (Heating ,Ventilation and Air Conditionin) system.


Check Internal and External Components:
One of the biggest contributing factors to a noisy heating system is a faulty relationship between the unit’s indoor and outdoor components. If internal and external parts are linked in such a way that they vibrate against each other, this will send plenty of sound through your home’s ductwork. Because ducts connect every room in your house when you have a central HVAC system, you may find it hard to escape all the noise. If you hear whining, buzzing, howling, or vibrations, have a professional check your HVAC system to ensure indoor ducts are independently connected to outdoor components.

How's Your Insulation?
Insulating your ductwork can also really cut down on unwanted noise. Sounds that come through ducts are generally caused by your heating system’s air handler. This metal box has a motor that can make parts vibrate as the system works. Adding a layer of insulation to the air handler can dampen the noise caused by these vibrations, sending less reverberation through the ducts. Insulation can also eliminate noises on the outside of your house, making you instantly more popular with the neighbors.

Acoustic Insulation:
Another way to insulate is with materials that absorb sound. This helps deaden noises, making them quieter and less intense until they eventually disappear at the farthest point from your system. Acoustic insulation can be added along ductwork, in the same way you might insulate plumbing pipes.

How's Your Fan?
Cleaning your home’s HVAC system fan is crucial to the quiet, efficient operation of your unit. The fan draws in dirt and dust, which can collect on the blades and interfere with its operation. Built-up debris can cause rattling and vibrations that will travel through the ducts and vents. If your fan is the wrong size for your system, it can also create noise as it struggles to keep up with demand. Keeping the fan clean and ensuring you have the right size fan for your unit will cut down on noise significantly.

Cleaning and Maintenance:
Regular duct and heat system cleaning and upkeep ensures your entire heating system is performing at its best. Professional maintenance keeps parts in good working condition and helps make sure that system components are installed correctly. A certified technician will tighten loose connections, fix gaps, clean parts, and add insulation to any system mechanisms that could be causing unusual noise. You should try to have a professional tune up and your HVAC system at least twice a year. The easiest way to remember is to schedule maintenance in the spring and in the fall, just before the peak cooling and heating seasons.

Get In On This "Ground" Floor Opportunity!

With the growing interest in "green" technologies and energy-efficiency in the home, one of the most popular environmentally and energy conscious innovations in the last several years is geothermal heating and cooling. Geothermal heating and cooling is a process that uses the natural heat storage capacity of the earth or ground water as a source of energy efficient heating and cooling.

Geothermal heating and cooling systems use a special kind of heat pump -- very similar to the air source heat pumps many homes use today -- to draw warm or cool air from below the earth's surface. Long considered prohibitively expensive, this eco-friendly type of home heating unit is becoming more and more affordable while still offering a clean, natural source of heat that can significantly lower utility bills. If you think it might be time to take a closer look at geothermal heating for your home, here are some things you should know.

Geothermal Heating and Cooling is Not Science Fiction
While many green technologies might seem like something out of a futuristic adventure movie, the reality of geothermal heating and cooling is here. Not only is this alternative heating/cooling method widely available all over the country, but its popularity is spreading. According to one source, requests for geothermal heating and cooling systems installation rose more than 266% in one year alone. The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) estimates that roughly 50,000 geothermal heat pumps are installed in American homes each year.

Geothermal Heating and Cooling Won’t Break the Bank
You will absolutely pay more up front for a geothermal heat pump than you would for a conventional heat pump or furnace. But the money you’ll save on home heating and cooling costs will add up so quickly that the device will more than pay for itself in just a few years. The EERE says that a geothermal heat pump allows owners to recoup additional costs in about 5 to 10 years. Furthermore, with so many homeowners—and home buyers—looking for environmentally responsible amenities, having a geothermal heat pump installed could be a major selling point when it comes time to sell your home.

Geothermal Heating and Cooling Can Go the Distance
The internal components of a geothermal heat pump will last about 25 years. The outdoor and underground mechanisms can last twice as long. Not even a high end furnace will keep running that long.

Geothermal Heating and Cooling is Versatile
Geothermal systems can also cool your home in the summer using the same ductwork you use to circulate heat in the winter. You’ll help reduce pollution and your monthly energy bills with a simple flip of the switch. You can also find geothermal heat systems are capable of heating your hot water, which can save you even more money.

Geothermal Heating and Cooling Can Save You Even More
Modern geothermal heat systems are easy to install, energy efficient, and more affordable than ever before. Many state governments are still offering rebates and discounts for homeowners who choose to install these environmentally-friendly systems in their homes. You could save thousands of dollars off the cost of a geothermal heat pump by taking advantage of these programs. And you may still qualify for federal credits if your system was installed after December 2007 and you have not yet applied for the incentives. A quick search of the Internet will reveal much more information about discounts, incentives, rebates, tax credits and programs available in your state or from the federal government.

As demand for alternative energy and home products continue to increase, it’s obvious that geothermal heating will maintain a pattern of growth for some time. Wait long enough, and there’s a good chance that the high initial cost will come down enough to make this heating system an affordable option for a majority of homeowners. But whether you decide to take the plunge or wait it out, there’s no denying that geothermal heating is a significant step toward environmental responsibility that doesn’t require a sacrifice of performance or lifestyle.

Keep Old Man Winter at Bay When You're Away!

Though winter is not usually an in-demand travel season, many of us do head out of town during the coldest months of the year. From snow birds and holiday travelers to skiers and warm weather enthusiasts, there are plenty of people looking for ways to relieve those deep winter blues by getting out of Dodge!

If you will be spending time away from home this winter, be sure to take precautions to ensure your home is ready for your extended absence. The following winterizing tips will help secure your home and prevent costly damage to your plumbing, HVAC system, interior and exterior while you are away.


Choose Temperature Wisely

You may be thinking you will save money on utilities while you are gone, but if you leave your home’s thermostat off or set too low you could come back to a major – and expensive – problem. Frozen pipes will burst, which can ruin your home’s plumbing and flood the house. Even if you live in an area that doesn’t get much snow or ice, it is still a good idea to set your thermostat no lower than 55 degrees. You will still save some money on energy costs, but your house will stay warm enough to keep your pipes from freezing.


Prepare Plumbing

Any kind of pipes can freeze and burst under the stress of neglect or frigid winter temperatures. No matter how cold it gets at your house, preparing your plumbing is essential.

Frozen pipes aren’t the only wintertime plumbing threat. Any crack or leak in the pipes could let in water that can cause significant damage to your home and personal property. If you are leaving your home for more than three weeks, it is best to have your water shut off completely and to drain the water lines. Insulate exposed pipes with pipe insulation available at most hardware stores.


Weather the Storm

For many of us, winter brings the harshest weather: heavy snows, ice, freezing rain, high winds, and sub-zero temperatures. A sudden winter storm while you are gone can wreak havoc on your house. Plan ahead and remove some of the risk factors from around your home and yard.

Secure outdoor furniture, grills, toys, garden equipment or lawn care supplies. Tie them down or put them in a garage or shed where they won’t be affected by bad weather.

Trim dead branches from trees and shrubs, especially where these limbs come close to your home or car.

Securely close and lock windows and skylights to prevent snow and ice from coming in.


Get the Lived-In Look

A great way to protect your home from would-be intruders is to make it look like you are still there. Set your holiday decorations and lights with timers, which you will find wherever you purchase holiday lighting. You might even want to put things like a few interior lights, the television, a radio or your computer on automatic timers.

Arrange for a neighbor to come over to clear walkways if it snows and to collect your mail. If you can get someone to check on your house every few days you can also dramatically reduce your risk of being victimized by a home invasion, or suffering major damage from frozen pipes.

Make Energy Efficiency a Top Priority in 2011

Each year around this time, millions of Americans make New Year’s Resolutions to lose weight, quit smoking, and other things to improve their health. But how many of us make New Year's resolutions to improve their homes...or save money on their heating and cooling costs? Not many.

The Horizon Comfort Zone doesn't want you to give up those health-related New Year’s Resolutions -- they're great! But why not sweeten the mix by focusing on your home heating and cooling system and overall energy usage, too? Energy-Efficient New Year's Resolutions are not only good for the environment, they're good for your wallet. PLUS -- they're pretty easy resolutions to do and keep...a lot easier than avoiding food, cigarettes and alcohol!

Here are some great energy efficient New Year's resolutions you should consider making for 2011:

• Change Your Furnace or Air Conditioning Filter: Dirty filters impede air flow and make your furnace or air conditioner work harder. This increases your energy consumption, as well as the likelihood of furnace or air conditioner breakdowns. Be sure to check your filters monthly. Replace or clean them according to the schedule recommended by your HVAC service technician or by the manufacturer -- for most heating and air conditioning systems during peak season, that's about once a month.

• Go Digital with a Programmable Thermostat: Why waste energy heating or cooling your home when you are not there? With a programmable thermostat, you can pre-set the times and temperatures in which your heater or air conditioner will run. According to industry experts, a programmable thermostat can save you as much as $200 per year in energy costs.

• Buy a Fan: Fans can help circulate warm or cool air evenly throughout rooms or even entire floors of your house. This reduces a lot of wear and tear on your heater or air conditioner.

• Consider Zoned Heating: Why heat or cool rooms or floors if you're not in them? With a zoned heating/cooling system, you can send heated or cooled air where you want it. No heat or air conditioning is wasted. And the energy savings can be huge.

• Seal Air Leaks: Feel a draft around doors, windows or vents? If so, you could be leaking warm or cool air. That's money out the door for nothing. And as a result of the leak, you are probably running your heater or air conditioner more than you need to; that's adding wear and tear to your heating and cooling system. Check out your local hardware store for caulk, tape and other sealants that you can use to seal leaks around your house. It's a very quick, easy and inexpensive fix and it can save you big bucks in energy costs.

• Stop Blocking Registers and Vents: Check around your house to see if your registers and vents are blocked by furniture and other obstructions If so, you are wasting heat and air conditioning. Move these items aways from vents and registers so you can fill your rooms with more warm air in winter and more cool, air conditioned air in summer.

• Get a Tune-Up: It makes sense to get your car tuned up periodically and inspected once a year. Doesn't it make sense to do the same for your heating and cooling system? Regular tune ups and maintenance are the easiest and most important things you can do to guarantee that your heater or air conditioner performs at peak efficiency and doesn't break down at an inopportune time. Tune ups can extend the life of your heater or air conditioner, too. Don't be one of those procrastinators who say they'll wait till next year to get a tune up...have your HVAC system checked at least annually...starting THIS YEAR!

• Upgrade to a More Modern Heating & Cooling System: Make this the year you get rid of that old clunker of a heater and that rusty bucket-of-bolts you call an air conditioner! Today's technologically advanced heating and cooling systems are a far cry better than the heaters and air conditioners made just a decade ago. They perform at much higher energy efficiency levels. They provide more comfortable heating and cooling. The last longer. They require fewer repairs. And they're a better value: they generally pay for themselves in energy savings in just a few years. Tax breaks, rebates, manufacturer discounts and other incentives make them a better buy today than ever before.

Happy New Year from The Horizon Comfort Zone!

When upgrading your HVAC system, always pay close attention to the ductwork. Flexible ductwork is a growingly popular alternative to traditional hard metal ducts. Before you decide whether or not it’s right for your home, consider the pros and cons carefully.


Pros of Flexbile Ductwork

Flexible ducts are cheaper than metal ones. This can save you money on installation and upkeep. If you are on a limited budget or would like to spend more of your remodeling budget elsewhere—like furniture or custom painting—it makes sense to save with flexible ducts.

Because the materials are cheaper, professional labor charges will be less, too. Installation is simpler, so you won’t have to pay top dollar for experienced labor.

Flexible ducts are…well…flexible. That means they can be installed in tight spaces where traditional metal ducts wouldn’t fit. If you’ve got sharp corners and lots of angles, flexible ductwork is a good option.


Cons of Flexible Ductwork

Flexible ductwork can restrict airflow more than metal ducts. Greater airflow means better HVAC system efficiency, but flexible ducts are more susceptible to interference from compression, pinching, and twisting. If ducts are installed in an attic or storage crawl space where boxes or other items could be pushed up against them, this can also diminish airflow. This decreased efficiency could mean higher energy bills.

Durability is also an issue with flexible ductwork. It doesn’t last as long as metal ductwork, it is thin and can puncture easily, and it doesn’t hold up to normal wear and tear like metal does. Over time, flexible ducts can become brittle and break or crack with even a slight touch.

Installing flexible ducts will save money initially, but you’ll have to replace it fairly often, and long before you would metal. This means you’ll incur that same initial cost several times for as long as you live in your home. For a more long-term solution, metal ductwork is a much better choice.

Flexible ductwork is made of a thin, pliable material. Not only does this make less durable than metal, but it also means that flexible ducts are more likely to become damaged in the short term. It’s difficult to install the material without damaging it, as rips and tears can happen very easily. Pests like mice and some insects can eat through the material, causing tears and holes that may be impossible to repair. Any sharp object stored too close to the ducts can easily cut through the ducts, as well. If your installers are not careful, you may end up paying more to replace damaged sections.


Contact Horizon Services with Your Ductwork Questions!

As with any major home renovation project, it’s a good idea to discuss the advantages and drawbacks of flexible ductwork vs. traditional metal ductwork with a qualified HVAC professional. An experienced contractor can help you decide if flexible ductwork is right for your home and will conduct a thorough inspection prior to starting any work. A professional can also help you weigh the cost savings of installing flexible ductwork against the additional expenses this type of material could bring on later. Talk to your Horizon Services comfort consultant; he'll be able to tell you wha ductwork options are best for your home.

Improved Air Flow Saves Energy, Saves Money, Improves Comfort

Environmentally responsible home improvements not only save the planet and leave more cash in your wallet, but they can also help improve the health of your home. If you’re overwhelmed by green home improvement options, keep it simple by installing or upgrading your home ventilation system and fans.

Proper ventilation is one of the best ways to improve your home’s indoor air quality. This can make a big difference if anyone in your family suffers from allergies, asthma, or other breathing conditions. Plus...vents and fans keep air circulating through your home so that warm and cold air are more evenly distributed; your heating and air conditioning systems don't have to work as hard or as often.


Green Fan Options

Install a Ceiling Fan: Ceiling fans are one of the easiest, most affordable options if you’re looking to improve your home’s energy efficiency. They move warm air throughout your house during the winter and take some of the work load off your air conditioner in the summer.

Install a Whole House Fan: Whole house fans are another affordable option. These powerful fans are installed near the attic, and cool your home by moving hot air up and out through the attic. Cooler air is drawn in through open windows. In warm climates, whole house fans can effectively supplement air conditioning; in cooler climates they can eliminate the need for an air conditioner altogether.


Green Ventilation

Install a Kitchen Hood Vented to the Outdoors: A kitchen range hood helps remove cooking odors, exhaust, and excess moisture from your home. While some range hoods vent to the attic, a hood that vents to the outdoors is better for your home’s structural integrity and indoor air quality.

Install a Bathroom Fan Vented to the Outdoors: Bathrooms are obviously the number one source of harmful mold and airborne bacteria that can infect the air you breathe. A bathroom exhaust fan, vented to the outdoors, will remove moisture from your home, cutting down on mold and mildew growth.

Install a Clothes Dryer Vent: Clothes dryers release tons of moisture into the air as they dry your clothes. This air circulates around your home, carrying chemicals from laundry detergents, toxins from synthetic fabrics, and deadly carbon monoxide. A properly vented dryer releases air outdoors, removing these harmful and potentially dangerous airborne pollutants from your home. To compliment a vented dryer, you may also want to consider installing an exhaust fan in your laundry or utility room.


Natural, Energy-Efficient Ventilation is Healthy Ventilation!

Anytime you can infuse your home with fresh outdoor air you are helping to improve the quality of the air you breathe. Here are more green ways to improve the health of air inside your home:

Install Windows and Skylights: Even more effective than fans are operable windows and skylights. Improve your home’s ventilation by simply opening a window. When you open windows on both sides of your home you can create a cross breeze that allows air to flow through your home more easily.

Design Green: If possible, consider the direction of wind against your home and the local weather conditions when designing the structure or replacing windows and doors. Aligning windows and doors to prevailing breezes lets you make the most of natural ventilation.

It's Not Just On Your Bread...It Could Be Growing in Your House!

Take a close look at your walls, floors and vents or inside closets. Especially in basements or areas that are out of the way and more prone to moisture exposure. See some streaks, spots or unusual coloration? Could be yellow, green, brown or black in color? If so, there just may be a fungus among us...mold.

Most of us know that old food can get moldy. And we've all seen what mold can do to an old pair of sneakers. But not everyone knows that these freaky fungi can get into and take root inside your home. And the results of mold infestation can be devastating.

Mold is certainly unsightly. It can even smell bad. Aww...let face it: mold is downright gross! But more importantly, mold is bad for your health. When mold grows excessively inside your home, it can seriously affect air quality. Airborne mold spores float through your home and are inhaled. This can lead to a variety of respiratory illnesses like bronchitis and persistent cough, as well as chronic conditions like allergies and asthma. The more mold you have in your home, the more likely it is that you or someone in your family will develop one of these health issues.


Mold Growth is Widespread

There are hundreds of different mold varieties, and these can be found virtually anywhere. Even if your home is spotless, mold could be growing in unseen places like behind walls, under floors, inside insulation, in ductwork, or along window sills. In these cases, you may not know about the mold for months, or even years. This allows growth to steadily increase over time; once you are aware of the problem it could mean thousands of dollars in cleaning and repairs.

Obviously, widespread mold growth is a problem that should be handled as soon as possible. However, even small amounts of mold can lead to breathing problems and illnesses for everyone in your home—pets, too.

Mold thrives in warm, moist, dark environments. Old or faulty HVAC systems can produce an environment where mold can grow. So can leaky pipes, poor drainage or any problem that allows water and moisture to accumulate.


Why Mold is So Harmful

• Volatile Organic Compounds: All types of mold produce substances called volatile organic compounds (VOC). These are naturally-occurring chemicals that are found in a variety of things used in the home. Some of the most common volatile organic compounds are generated by paints, household cleaners, and adhesives. The VOC in mold creates that distinct, musty odor that we usually associate with mold or mildew growth. The smell alone can decrease the quality of air inside your home and will gradually worsen if the problem is not eliminated. Research has shown that humans who are exposed to a high concentration of indoor mold growth experience a wide range of symptoms, from allergic reactions to issues with the central nervous system including nausea, headaches, and diminished mental capacity.


• Allergens: Every type of mold also produces allergens. Mold grows in tiny clusters called spores. These spores release invisible toxins that travel through the air inside your home and can trigger allergic reactions when they are inhaled. These reactions are the same as you might experience with any other environmental allergy: itchy, watery eyes; sneezing; coughing; nasal congestion and sinus pressure; and even skin rashes.

Prevent Mold Growth

For visible mold, clean the area with an antibacterial cleaner or a common bleach and water solution. This will get rid of existing mold and will prevent new growth. Remember that mold and mildew thrive in warm, moist places so be sure that your bathrooms are vented properly, open windows whenever possible to allow fresh air into your home, and never leave damp clothing or linens lying around.

If you suspect mold is growing in unseen areas of your home, hire a professional to perform a thorough assessment. You may need to contract with a professional cleaning service or make some repairs if the problem is serious.

Standards are Getting Tougher for Energy-Efficient Heating and Cooling Systems and Other Appliances

According to a March 2010 press release, the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) have been implementing stricter policies to improve the federal Energy Star program and to increase consumer confidence in the label. The action comes at a crucial time, when more American consumers are both struggling financially and turning to home heating and cooling equipment and home appliances that will save energy and reduce utility bills.


Strengthening Testing and Enforcement

The EPA and DOE have begun a two-part process to expand Energy Star testing:

• The DOE recently started testing on six of the most common Energy Star product types: freezers, washing machines, dishwashers, water heaters, refrigerator-freezers, and room air conditioners. The DOE will conduct testing on more than 200 models at independent laboratories over the next several months.


• The EPA and DOE are currently working on a system that will make the Energy Star qualification process more rigorous. Changes include testing by approved third-party labs, ongoing verification testing, and new manufacturer compliance cooperation procedures.

On the enforcement front, the EPA and DOE have been working to identify and resolve issues with manufacturers who fail to meet Energy Star standards. This includes actions taken against nearly three dozen manufacturers since January 2010:

• January 7, 2010: The DOE announced that freezer manufacturer Haier had signed a consent decree on four of its models that were found to consume more energy than the company reported. As part of their agreement, Haier was ordered to notify all impacted consumers, repair defective units at no cost, and pay a fine of $150,000 to the US Treasury.


• January 25, 2010: The DOE disqualified 34 compact fluorescent lightbulb models from more than two dozen manufacturers. These bulbs did not meet all Energy Star criteria for CFL.


• January 28, 2010: The DOE took action against four companies that manufacture showerheads because the products were not certified to meet federal water conservation standards.


• February 4, 2010: The DOE initiated a civil penalty against an air conditioner and heat pump manufacturer because some of its products were not certified, while other products were certified without the proper testing.


• March 7, 2010: The DOE commenced enforcement actions against two more showerhead manufacturers suspected of marketing products that did not meet federal water conservation standards.


• March 11, 2010: The EPA terminated their partnership with US Inc./US Refrigeration based on the company’s history of Energy Star logo misuse, unresponsiveness to EPA communications, and a habitual failure to comply with Energy Star guidelines.
  
  

Energy Star Brand Aims to Bolster Consumer Trust

The Energy Star program already has several systems in place to ensure consumer confidence in products that carry the Energy Star label. The requirements for certification are as follows:

• To receive the Energy Star label, companies must submit to the federal government data that shows their product(s) meets clear and quantifiable energy efficiency standards.


• The DOE and EPA conduct regular third-party laboratory and “off the shelf” testing of a range of Energy Star products to ensure continued compliance.


• Because the Energy Star label is so attractive to buyers, market competition drives compliance from manufacturers. Manufacturers frequently test competitors’ products to ensure compliance and can report violations to the EPA or DOE.


• When a manufacturer is found to be in violation of Energy Star policies, the label is removed from the affected product, corrective measures are outlined, and if changes are not made the Energy Star partnership may be terminated.

A British Thermal Unit -- or BTU -- is the measure of an air conditioner’s power output and cooling capability. Normal BTU range for most air conditioners goes from around 5000 for a small window unit to 30,000 or more for a central AC system. BTU output is directly related to the size and cost of a unit—lower BTU means less power and lower cost, higher BTU means more power and higher cost. When you’re shopping for a new air conditioner, pay special attention to BTU because this is the best indicator of whether the unit is powerful enough to meet your needs.


What is a BTU?
If you’re talking about air conditioners, BTU describes the power capacity of a specific unit. Generally, BTU output corresponds to the size of the space an AC can cool—a unit with more BTU can cool a larger room. About 20 BTUs are needed for each square foot of space in a room or home. Other things to consider are the height of ceilings, size and number of windows, and amount of insulation.

Still, BTU is a fairly accurate indicator of cooling capability, though it usually makes sense to adjust down. For example, if your living room is 10 feet by 15 feet and has a total area of 150 square feet, you’d multiply that by 20 BTUs to get 3000. Therefore, you’d need an air conditioner with at least 3000 BTUs to effectively cool your living room. However, when you take into account the other factors that impact the space—like cathedral ceilings, large windows, or an unusually warm climate—you may find that 3000 BTUs are not enough to keep you cool. In that case, it’s obviously best to choose a unit with higher BTU.


BTU Range
There’s a wide range of BTU outputs available in both commercial and residential air conditioners. Most residential units average 5000 to 30,000 BTUs. 12,000 BTUs equals one ton of air; some units are marked with a measurement in tons rather than BTU. A “2-ton” AC, for instance, means that the unit has an output of 24,000 BTUs.

Portable air conditioners average about 5000 to 12,000 BTUs. Wall and window units can reach upwards of 24,000 BTUs at the high end. Mini split systems range from 9000 to 24,000 BTUs, while multi-split systems and central air conditioners can put out 30,000 BTUs or more. Industrial air conditioning systems frequently have BTU output significantly higher than 30,000.

Not only will BTU tell you how much room an air conditioner can cool, but it can also give you an idea of how much you’ll have to pay to run it. The more BTUs a unit uses, the more it will cost to operate. To save money on utilities, look for air conditioners with a high Seasonal Energy Efficiency Rating (or SEER). Additional features like programmable thermostats, timers, fans, and power-saving settings can reduce strain on your system, boost efficiency, and lower your energy costs while still keeping your home cool.

The Environmental Protection Agency (EPA) has managed the Energy Star labeling program for nearly twenty years, and has helped Americans cut greenhouse gas emissions and save billions on utility costs. In 2009 alone, Energy Star partners helped consumers avoid greenhouse gases in an amount equal to that of the output of 30 million cars and save more than $17 billion on utilities.

The EPA recently announced a new set of more stringent guidelines for Energy Star-certified home construction. These new conditions will raise the bar of energy efficiency for qualified homes, making them at least 20 percent more efficient than homes built to the previous standards. Homeowners will likely see at least a 15 percent drop in their utility bills, as well.

The EPA’s updated guidelines will further solidify the Energy Star brand as it’s applied to new home construction. Energy Star homes will continue to represent significant increases in energy efficiency over homes that are built to standard builder practices and codes. The new regulations will go into effect as of January 2011, though many builders and contractors are likely to start implementing the changes much earlier than that.

If you’re interested in learning more about Energy Star new home construction and how the new guidelines may affect your project, the key components of the revised plan are as follows:

• Homes must have a complete thermal enclosure system. This includes complete air sealing around windows and doors, adequate insulation around all assemblies, and high performance windows. This not only makes the home more comfortable, but also helps lower utility costs.


• Comprehensive central heating and cooling systems must meet Energy Star standards and be installed by qualified professionals. Energy efficient heating and cooling systems are designed to increase comfort, offer better moisture control, and operate quietly. They are also outfitted with fresh air ventilation to improve the quality of air inside the home.


• Because Energy Star homes are so tightly sealed and insulated, they must be equipped with a total water management system. Flashing, moisture barriers, and durable membrane details are all crucial elements in keeping water away from roofs, walls, and foundations. This reduces mold growth, which improves indoor air quality, and extends the durability of these structures.


• With energy efficient lighting and appliances certified by Energy Star, homeowners can enjoy even more energy savings without sacrificing performance quality.


• Energy Star and the EPA will now require all new construction to be third party verified by an independent home energy rater. These inspectors will conduct thorough, detailed examinations using specially designed diagnostic tools to measure performance of key systems.

The new EPA guidelines should come as no surprise to those who make their living building green homes. The revised regulations certainly don’t break much new ground, but they are solid, relatively simple changes that should translate into substantial utility savings while further reducing homeowner’s energy dependence.

If you are a homeowner considering an Energy Star certified new home construction, you can find out more about the program by visiting http://www.energystar.gov/ or by speaking with an experienced HVAC or home contractor in your area.

Two of the most common mistakes people make when purchasing central air conditioning are 1). Getting a system that is too large for the size and style of their house, or 2). Getting a system that is too small. This usually happens when an air conditioning contractor recommends an oversized unit, telling you that “bigger is better.” Or when a contractor tries to sell you a smaller unit so that they can underbid other contractors and make sure they get the job by offering you a bargain.

Here's the truth: When it comes to central air conditioning systems, bigger isn't better; it’s just more expensive. And smaller may save you some money upfront, but you almost always get what you pay for.

Consider some of the problems you can get into from buying an oversized or undersized air conditioner...


Air Conditioner Too Big:

An oversized central air condtioning system will turn on and off much too frequently, which will wear down your equipment and waste electricity. Plus, the larger system will cost you more upfront and more to operate.

This frequent cycling on and off will also make your indoor temperatures fluctuate up and down more, resulting in a less comfortable environment. The oversize unit will lower temperature too quickly and then turn off before removing the appropriate amount of humidity. This is another reason why homes with oversize units feel cold and damp -- the humidity is never removed!

The EPA (Environmental Protection Agency) estimates that nearly half of all existing air conditioning equipment is over-sized They estimate that this costs homeowners 20% each year in wasted energy!


Air Conditioner Too Small:

An undersized central air conditioning system will cause your air conditioner to overwork and may fail to keep your home adequately cool. A small air conditioning unit will lower humidity, but will not lower the temperature enough, so the air will feel dry but warm. Pluse the air conditoning system will run constantly; over-running your central air conditioning equipment will lead to premature breakdowns and a short lifespan.

And even if you get the right size air conditioning equipment, you also have to beware of “buying too small” when it comes to your air duct or airflow system. According to the National Comfort Institute states, it’s not unusual to see return air systems undersized by 30-50%. In fact, many common central air conditioning equipment problems including compressor burnout, frozen indoor air conditioning coils -- are often a result of improperly placed and installed air distribution systems.


Be Like Goldilocks!

The central air conditioning system that is ideal for your home comfort and budget is neither “too big” nor “too small,” but is “just right”. When shopping for a new central air conditioning system, be sure that your air conditioning contractor performs a thorough analysis and measurement of your home from top to bottom -- including your air ducts and air flow system.

Also, as part of this analysis, make sure that your central air conditioning contractor performs a load calculation. This is a mathematical computation that allows a contrcator to precisely estimate the performance needed to adequately cool your home and the capacity that will be required for your new air conditioning equipment to deliver that performance. A load calculation is good way for you to make sure that the central air conditioning equipment you’re buying is not over-sized or under-sized. Be sure to ask for a copy of the load calculation to be submitted with the proposal; this will assure you that the contractor takes capacity design seriously and that he’s not just going through the motions.

Time for a new central air conditioning system? The average air conditioner lasts about 15 years, so if you live in your home for more than 10 years or so, there’s a good chance you’ll eventually have to replace your system. If you have central air conditioning that was installed back in the 1990s (or earlier), keep in mind that today's air conditioning systems provide significantly greater cooling power and energy efficency.

Installing a central air conditioning system is one of the most significant steps you can take in improving the overall comfort of your home. Central air conditioning will also add value to your home, as it’s a very attractive selling point for potential buyers.

That being said, a new central air conditioning system is a major household investment and not a purchase one should make without doing some serious homework. If you’re due for an air conditioning system upgrade, there are several important considerations that can help ensure you get the best possible performance, energy efficiency and value.

Before you commit to a new central air conditioning installation, think about the following:.

• Try Maintenance First. Have you been replacing the air conditioner filters according to schedule? Have you been scheduling a regular air conditioning tune-ups and cleanings? The problem may not be your air conditioner, but you! If your current air conditioning system seems to be operating at less than full capacity, have a professional air conditioning service technician come to your home to inspect it before you blow your savings on a brand new air conditioning system. Sudden changes in the function of an air conditioner that’s been performing just fine up to a point could mean that simple maintenance is in order, rather than a complete system overhaul. A certified professional can clean your system, run diagnostic testing, and make repairs or adjustments as needed. An experienced pro will also be able to tell you if it’s time to replace your central air conditioning system.


• Totally New vs. Upgrading Your Existing Air Conditioning. You may not need an entirely new central air conditioning system at all...just some modifications to your existing system to enhance its performance. Upgrading an aging central air conditioning system requires a much different set of considerations than installing a new one. You’ll want to make sure you match brands and models, and choose new components that are compatible with older ones. If you’ll be replacing an old air conditoning system completely, you may incur extra costs for removal and disposal of outdated parts.


• Air Conditioning Installation Circumstances. Be sure to communicate with your installation professional so he or she knows how best to approach your job. If your new air conditioning installation is part of a larger home renovation project, you may be able to save significantly by arranging for installation at a specific point in the job. Also, when your air conditioning professional is in the loop, he or she will be much better equipped to determine the best kind of system for your home and a much more accurate estimate.


• Air Conditioning Power Requirements. Central air conditioners measure cooling capacity in British thermal units (Btu) per hour. Generally, you need about 12,000 Btu per 1000 square feet of well insulated space or 400 square feet of inadequately insulated space. Your home’s structure, windows, sun exposure, and climate will all impact your cooling needs. The best way to get an idea of what you need for your home is to talk to an HVAC professional. While an air conditioning technician may suggest products or installation features that might cost you more up front, they will likely save you much more in the long run.


• Replacing an Aging Air Conditioning System. Like many other household appliances, central air conditioners have become significantly more energy efficient in the last ten years or so. If you’ve noticed a dramatic decrease in your system’s ability to cool your home—temperatures are inconsistent, the system seems to be coming on more frequently or running longer, or your monthly utility bills are steadily increasing—it may be time to replace your air conditioner. If your new air conditioner will be tied into an existing system in your home, talk to an air conditioning contractor about compatibility and installation options.


• Air Conditioning System Accessibility. Installing a central air conditioning system means your installation technician will need access to your home’s air ducts. The easier the access, the less you’ll be charged in hourly labor costs. If your home is older or has limited duct space, you might want to think about purchasing a mini-duct or ductless air conditioner. These alternative systems are a much better and more cost effective choice for homes where installing traditional ductwork would be prohibitive.


• Look for Energy Star Appliances. Choosing environmentally responsible products can be a challenge; for appliances and home electronics, the Energy Star program makes it easy. Simply look for the blue Energy Star label and know that you are getting the most eco-friendly, energy efficient air conditioner for your money. Air conditioning systems can have a huge impact on your summer utility bills, so it makes sense to look for an appliance that’s going to reduce your home’s overall energy consumption and save you money. Shop for air conditioners with a high SEER rating (most units range from 10 to 17). If you’re installing a central air conditioner, make sure your contractor knows your preferences and ask for a unit with the highest SEER rating possible.


• The Noise Factor. This is your chance to get rid of that noisy old air conditioning unit that rattles and hums every time it powers on. Inexpensive air conditioners—either window-mounted or central—can cause a lot of noise pollution, especially if you have to install them in a bedroom, living room, or near a deck or patio. Consider placement carefully, and avoid areas close to living areas, bedrooms, and close to the neighbors. To guarantee quiet operation, go with a higher-end, more expensive model.


• Sun Exposure. No matter how energy efficient your air conditioner, it will struggle to perform properly if it’s placed in direct sunlight. Try to install a new unit in an area of your home with plenty of shade, or plant shrubs or small shade trees close by.


• Consult an Air Conditioning Pro. A professional HVAC technician will be able to answer any questions you have about installing a new central air conditioning system in your home...from proper placement to energy efficiency ratings to correct sizing for your square footage. If you are unsure about any aspect of air conditioning system purchasing or installation, call your local air conditioning contractor for advice.

What You Can't See May Be Costing Hundreds of Dollars in Wasted Heating and Air Conditioning Bills!

Your heating and cooling systems use more energy than any other system in your home. Typically, 46% of your entire utility bill goes for heating and air conditioning alone. For many homeowners, a large chunk of that heating and cooling bill may be completely wasted...and the culprit is hidden out of sight beneath your feet and over your head.

Your home’s air duct system is a complex network of tubes made of sheet metal, fiberglass or other materials that runs throughout your walls, floors, and ceilings, carrying heated or cooled air from your home’s furnace and central air conditioner to each room. But if these air ducts have leaks or are poorly insulated, as much as 60% of your heated or cooled air can be lost before it even reaches the registers in these rooms. That can result in a lot of wasted energy...and money. As well, ducts that are damaged or don’t work properly can create serious, life-threatening carbon monoxide (CO) problems in the home.

Sealing and insulating air ducts that are in unconditioned spaces -- such as an attic, crawl space or basement -- is extremely important and can be a great way to get a handle on out-of-control heating and cooling costs. Insulation if fairly easy to install on existing duct work. If you are buying a new duct system, consider one that comes with insulation already installed. Sealing your air ducts to prevent leaks is even more important if you want to save energy and money. If the supply ducts are leaking, large amounts of heated or cooled air can be forced out of holes or unsealed joints and lost. In addition, unconditioned air can be drawn into return ducts through unsealed joints. In the summer, hot attic air can be drawn in, increasing the load on the air conditioner. In the winter, your furnace will have to work longer to keep your house comfortable. Either way, your energy losses can cost you big bucks.

In most cases, air ducts in unconditioned spaces should be sealed and insulated by a qualified HVAC and duct work professional using appropriate sealing and insulation materials -- especially if the air ducts are concealed. If you're a handy do-it-yourselfer, here are a few simple tips to help with minor or temporary repairs to visible duct work.

• Check your ducts for obvious air leaks. Look for sections of duct work that should be joined but have separated, as well as for holes or punctures.


• If you use tape to seal your ducts, avoid the common cloth-backed, rubber adhesive duct tape that you can get at any old store. This garden variety duct tape tends to fail quickly. Instead, most HVAC and duct contractors recommend professional quality mastic, butyl, foil or other heat-resistant tapes. Look for tape with the Underwriters Laboratories (UL) logo.


• Be award that insulating ducts in the basement will make the basement colder. If the heat ducts are fully insulated, water pipes and drains in the basement could freeze and burst if the basement temperature gets too cold. Use electric heating tape wrap on your pipes to prevent this. Also consider insulating your basement walls to hold more heat in or installing heating in your basement.


• If your basement has been converted to a living area, hire a professional to install both supply and return registers in the basement rooms.


• Make sure that a well-sealed vapor barrier exists on the outside of the insulation on cooling ducts to prevent moisture from building up.
