How Do I Check My Home For Air Leaks?

Don’t Let Air Leaks Affect Your Energy Bills

When outside air gets into your house or climate-controlled indoor air escapes, your heating or cooling system has to work extra hard to maintain the proper temperature. To avoid this problem, it’s smart to find and fix any leaks.

Check These Spots for Leaks

You’re most likely to find air leaks in spots where two building materials meet. Air often escapes through cracks or gaps between the materials. Spots to check include:

  • Around doors and windows
  • Along outside corners
  • At the top of the foundation
  • Where utility lines enter the house
  • Along the base of the chimney

You can use an incense stick to test for leaks. First, close up your house by shutting and locking all exterior windows and doors. Turn on all your exhaust fans and the dryer. Shut every vent or damper.

After that, light an incense stick. Hold it near all suspect spots. If you notice the smoke moving, that’s a sign that you have a leak there.

Don’t Forget Your Ductwork

You can also have air leaks in your home’s ductwork. These typically occur at spots where two pieces of ductwork meet. Extra dust inside your home and inefficient heating or cooling can be signs of leaks in the ductwork.

To detect a major leak, you can hold your hand by the duct while the system is running. If you feel air blowing on your hand, there’s a leak. Additionally, you can use the incense test to identify smaller leaks.

Fix Air Leaks

To stop air from getting into small cracks, seal them with caulk. Spray foam can be useful for larger ones. It may be better to fill some large cracks with sections of drywall or insulation. For ductwork leaks, you can wrap foil tape or insulation around the affected joint.

For the most thorough detection and repair of air leaks, you should rely on a professional. To get started, contact the experts at Barker's Heating & Cooling in College Station, TX, today.
