Of all the air that circulates in an average home, 25 percent of it passes into the attic through supply duct leakage. This escaped air has already been filtered and treated by your heating or cooling system and you have already been charged for the energy used to do this. So, in effect, 25 percent of your heating or cooling costs are literally money out the window! But that's just the beginning and it's a great reason why you should call a professional Las Vegas HVAC contractor like Air Doctor Inc. to help reduce your energy costs..
When circulating air is constantly leaking into the attic, the home is in a state of negative pressure and the attic is in a state of positive pressure. You are basically losing more air from inside the house than you are putting back in. Meanwhile, your cooling or heating systems are running on overtime to replace lost air.
Even worse is that your home will resolve the air pressure imbalance by trading air with the attic. Air from the attic is loaded with nasty dust, allergens, dust mites and fiberglass particles.
There are many causes for leaky or cracked air ducts. The most common cause is exposure to regular temperature extremes. Air ducts are concealed within walls and tucked into other inaccessible spaces within your home. Ducts are usually not covered with insulation or protected by other barriers that shield most of your house from outside elements.
The older ductwork gets, the more likely it is to suffer fissures, leaks and small cracks. These blemishes continue to get worse and to increasingly compromise the quality of your indoor air. New air ducts can also be afflicted. They may have been improperly installed or the workmanship might have been second-rate. If you suspect air duct leakage, schedule a consultation with Las Vegas HVAC contractor Air Doctor Inc. whether your ductwork is old or new. If your air ducts are leaky, having them properly sealed is a very wise investment!
Air ducts are like soldiers who keep fresh, clean, heated or cooled air circulating within the perimeter of your living space. These "sentinels" also keep contaminated air from entering your home, thus protecting you from toxic airborne particles.
When air ducts develop cracks or leaks, they can no longer perform properly, and your family is exposed to harmful airborne particles on a daily basis. The only way to correct this problem is to have cracked ducts professionally sealed so they can function correctly and preserve the quality of your air. With sealed air ducts, it's much harder for airborne contaminants to invade your air circulation system. Those that do are easily filtered out by your air cleaner.
In order to work properly the ductwork system must be precisely pressure-balanced. Fissures, cracks or breaks, even very small ones, can disrupt the pressure balance completely. When air ducts are leaking, heated or cooled air within your home cannot circulate properly.
What's more, air from outside will be absorbed into the house through the air duct cracks. This contaminates indoor air even more. It also makes your home heating and cooling systems work harder to compensate for the influx. The result is that these systems cost more to run.
When air ducts are professionally sealed by an HVAC contractor in Las Vegas, your heating and cooling systems will function much more efficiently, maintaining optimal temperatures throughout the house. Even better, you'll save a considerable amount on your energy bill because the system won't have to overwork to keep pace with disruptions in the air flow or negative pressure. Finally, your heating and cooling system will last longer and develop fewer problems along the way.
Having leaky ducts professionally sealed can increase the property value of your home and help to avoid expensive heating and cooling system breakdowns in the future. If you suspect that air duct leaks are causing uneven heating and cooling or you notice that your heating or cooling systems are working harder than they should, you may have ductwork leaks. Another indication of air duct leakage is a monthly power bill that keeps going up, even though energy usage seems to remain the same.
