You have high summer cooling bills
- You have rooms that are difficult to heat and cool (one room that is hotter than the rest during the summer)
- You have stuffy rooms that never seem to feel comfortable
- Your ducts are located in an attic, unfinished basement, crawlspace, or the garage
- You can find tangled or kinked flexible ducts in your system.
Sealing and insulating ducts can help with common comfort problems, such as rooms that are too hot in the summer of too cold in the winter.
Indoor Air Quality
Fumes from household and garden chemicals, insulation particles, and dust can enter your duct system, aggravating asthma and allergy problems. Sealing ducts can help improve indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home.
During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork in your heating and cooling system may cause “backdrafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks can minimize this risk.
Leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent. Sealing and insulating ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.
