Techniques to Check Your Home for Air Leaks
March 1, 2019
Your home should be a secure setting that is comfortable in each season of the year. Many homeowners are unaware of air leaks that may be present. These can cause the HVAC system to work harder than necessary to keep the interior setting warm or cold. If you’re ready to seal your home, there are a few techniques and tips for discovering where the leaks are.
Look in the Right Places
Although leaks can be challenging to detect, there are still common places where they are most likely to be. These are the spots where you should begin your inspection. Cracks and holes commonly form on knee walls that support attic rafters. They also appear near plumbing vents, recessed lights, air ducts, plumbing vents, and wiring holes. Use a flashlight to perform a thorough visual inspection. You can have someone stand on the outside of the building at night to find cracks where the flashlight may be shining through the walls. During the test, use blue tape to mark areas that need to be sealed.
Use an Air Leak Detector
Air leak detectors are useful devices that offer a high level of accuracy in finding where leaks are present. Professional smoke pencils produce a fog that will allow you to check for where air may be entering the building.
Light a Candle
Close the doors, windows and chimney flue in your home to seal the house of air that may enter the building. Walk around the perimeter of each room with a candle while placing the flame close to areas where leaks may be present. Keep a close eye on the flame, which will begin to flicker or move horizontally if air is entering the building. To ensure you know the areas that need to be sealed, take note of places where the candle flickers. This will help reduce the demands put on your heating system.
