When most homeowners think of HVAC maintenance they typically think of physical things like cleaning and replacing the air filter. One of the biggest things you can do to help your HVAC system perform well is to seal the leaks between your home and the outdoors. Even though this doesn’t always involve components of your heating or cooling system, leaks can force your system to work harder and less effectively.
Finding Air Leaks in Your Home
While modern homes are much better than older homes when it comes to air sealing, newer homes can still have significant issues. You can check for leaks by yourself, it just takes some time and effort. Go to the places in your home that are likely to have leaks and either feel around or use something like an incense stick that will alert you to any air that is entering/exiting.
The worst leaks are typically located:
- Around doors and windows
- Where HVAC piping enters the home
Sealing Air Leaks in Your Home
Once you have found any leaks it’s time to seal them. Once again this is a simple task, you will need caulking, weatherstripping and possible spray foam. Caulking is usually used for small leaks on stationary components of windows and doors. Weatherstripping is designed for moveable components, like in the joint of a door. Spray foam is able to seal large holes or cracks, often on the outside of the home.
If you need to improve your attic insulation, you may be able to do it on your own, but calling in a professional to get the best seal is recommended. Using either fiberglass or cellulose, your attic can be sealed from the rest of your home.
