Easy Ways to Check Your Home for Air Leaks


Loose doors, broken weather stripping, and wall cracks can all create drafts throughout a home. These air leaks cost you money on heating and cooling. The drafts force your air conditioner or furnace to work harder to counteract the air loss. Your comfort will decrease as well because your system might fail to maintain a consistent temperature.

Spot Problems With a Visual Inspection

Many air leaks are easy to locate and repair yourself with fresh caulk, insulation, weather stripping, or replacement doors and windows. To complete a thorough indoor and outdoor inspection of your home, look for gaps or cracks in the following areas: 

  • Exterior building corners 
  • Around water faucets 
  • Where walls meet the foundation 
  • Electrical outlets and light switches 
  • Around doors and windows 
  • Window air conditioners 
  • Dryer vent 

While you’re sealing leaks, you can also benefit from a seasonal inspection of your heating and cooling system. In the Phoenix area, Collins Comfort Masters provides residential AC tune-ups that will improve performance and enable more efficient power usage. This service also has the potential to extend the life of your equipment.

Perform a Building Pressurization Test

Professional companies perform a test that seals a home and attaches a blower to a door to alter internal air pressure. You can mimic this pressurization test with a few simple steps. 

  1. Shut down gas-burning appliances. 
  2. Close doors, windows, and fireplace flues.
  3. Turn on your ventilation exhaust fans and clothes dryer.
  4. Light an incense stick and travel slowly through every room.
  5. Smoke movement will reveal air leaks.

This method can be very effective at finding air leaks that cannot be easily detected with a visual inspection.
