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 704-873-1749 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.

Air Quality

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

Fair Prices, Great System Engineering, and an Excellent Crew

A great company to work with! Fair prices, great system engineering, and an excellent crew. I put a major challenge to Griffin to find a way to come up with a new hot water heating and HVAC system that would free up more room in the attic for a new room. We also wanted to get better control of the air flow through the house and a quieter condenser outside in our backyard so that we could enjoy our new deck. Challenge accomplished on all fronts and the quality of work and detail to attention was outstanding! Hot water heater moved from the attic to the outside (tankless), and the new Carrier Infinity system allowed them to reposition the duct work in the attic and the main unit to make much more space for the expansion. The new system is nearly silent, much better flow throughout the 3 zones in the house, and my energy bill has been nearly cut by at least 1/3 to 1/2! The price at the end was exactly what was quoted, and I know that they put more work into the project than initially projected.
