5 Signs Your Home has Poorly Performing Ducts
When looking for ways to make your home more comfortable and energy efficient, drafty doors and windows are an obvious place to start. But did you know that 20-40% of the air moving through the duct system (air you are paying to heat and cool) is lost to leaks, either through holes or poor connections? That’s right! Your once comfortable home may be less comfortable, and you are likely spending more on high utility bills for less comfort, as a result of leaky ducts.
How do you know that your home has poorly performing ducts?
If you’ve been regularly adjusting the thermostat, chances are good that the problem is with the air ducts. Here are 5 more telltale signs:
1. You have high summer and winter utility bills
Leaks in the ductwork cause your HVAC system to work harder in an effort to maintain the proper temperature. The furnace or air conditioner run constantly, increasing energy costs without maintaining comfort because a significant portion of the heated or cooled air being generated never makes it into the living spaces.
2. You have rooms that are difficult to heat and cool
As heated or cooled air escapes into crawl spaces, certain rooms may always be too hot or too cold. Raising or lowering the temperature to compensate can negatively impact the comfort in other areas of your home.
3. You have stuffy rooms that are never comfortable
Compromised air flow can leave some rooms feeling as if they never have fresh air circulating in them.
4. Your ducts are located in the attic, crawlspace or the garage
Because most ductwork is out of sight and difficult (or impossible) to reach, most homeowners are unaware of the problem.
5. You find tangled or kinked flexible ducts in your system
Much like a kinked or tangled garden hose prevents water from flowing, kinked air ducts can prevent proper air flow and also create weak spots that eventually lead to leaks.
Benefits of Duct Sealing
A properly designed and installed duct system (one that has secure connections and no leaks) contributes to the overall comfort, safety and energy efficiency of a home. While it is possible to tackle duct sealing as a do-it-yourself project using mastic sealant or metal tape, you will only be able to access a portion your home’s ductwork. Sealing your ducts from the inside is the most cost-effective way to save money on your energy bills.
Aeroseal of Colorado uses an innovative, patented technology — developed at U.C. Berkeley with funding from the Environmental Protection Agency and the U.S. Department of Energy – that stops leaks from the inside out. In fact, this breakthrough technology is so effective that the Department of Energy included Aeroseal among the most beneficial energy technological advances ever developed. Aeroseal has also been honored with Popular Science Magazine’s “Best of What’s New” and the Department of Energy’s “Energy 100” award.
