Living room with brown and light green accessories


According to the U.S. Department of Energy’s Energy Star program, leaky ducts in attics or crawlspaces can account for 20 percent or more of a home’s heating and cooling energy losses. This results in higher utility bills for you and difficulty keeping your house comfortable.

A few signs you may have leaky ducts are if you have:

  • High utility bills in summer and winter
  • Difficult-to-heat-and-cool rooms
  • Stuffy rooms that never seem to feel comfortable
  • Attic, crawlspace, or garage ducts
  • Tangled or kinked flexible ducts in your system

What Can You Do About Leaky Ducts?

Run your system, and check all the ducts and joints you can access. You can seal these yourself with mastic or foil-backed tape. You should also seal around where the duct meets the wall. Duct tape is actually not recommended for ductwork, and any fabric-backed tape will deteriorate over time. If you have questions about appropriate tape call us at 865-689-5290 or talk to a representative at your local hardware store.

The following maintenance will require an HVAC professional:

Duct Insulation

We recommend insulating your ducts. This ensures that the air maintains the correct temperature as it travels to the living spaces in your home.

Duct Testing

You can have your ducts tested. One of our certified technicians will take a reading of the air pressure in your ducts and can analyze how much air you lose. From there we can make suggestions about how to improve efficiency.

Duct Cleaning

You should have your ducts cleaned. Over time, dust, mites, bacteria, and other things get sucked into your vents and build up in your ductwork. Imagine all the years of dust in your house getting blown around into the air you breathe.

You can also have an ultraviolet (UV) light installed in the ductwork. This uses UV radiation to sterilize air, destroying bacteria as well as mold and fungal spores. This serves to greatly improve your indoor air quality.

Air Quality

Indoor Air Quality, or IAQ, is very important to the health and well-being of you and your family.

“Chris and Patrick, along with all the AA Air people, are great. We had a large job of total duct replacement and a new unit installation. The job was well done and in a timely manner. At the end of each day they cleaned up and were always very respectful of myself and my home. I love the new unit and duct system. My home temperature has never been as well maintained. A tri-level home can be difficult to heat and cool and now I can be in my upper bedroom or basement and the temperature is the same. I would absolutely recommend.”
