How Do I Check My Home for Air Leaks

Keeping your home cool in the summer and warm in the winter is very important. While you can have a quality HVAC system installed, you may still have a hard time achieving your desired temperature if you have air leaks in your home. Even small air leaks could greatly alter the temperature of your home, which could also lead to an increase in your energy bills. Fortunately, there are several ways to identify air leaks and to repair them.

Check Windows and Doors

One of the most common ways that air will leave your home is through cracks in your windows and doors. Over time, even quality windows and doors will continue to contract and expand, which will eventually cause small leaks. If you are able to see daylight around the window or door frames, then it is a clear sign that there is a leak. Also, if your windows can be shaken easily, it is also likely that there is an air leak. Smaller leaks such as these can normally be repaired with caulk or by replacing the weather stripping.


Another common place for air leaks is in your ductwork. If there are leaks in your ductwork, it will prevent treated air from reaching your vents and the rest of your home. One of the best ways to identify the location of a leak is through a smoke machine. These machines will release smoke into your ducts. You should then be able to clearly see the smoke sneak out through leaks and cracks in your ductwork. These cracks can often be temporarily sealed with duct tape but may require you to have them professionally sealed and insulated.
