Fixing air leaks in your home is the best way to ensure you are not wasting money. When air leaks out of your house, your AC uses more electricity and you feel less comfortable. Air leaks occur when holes, cracks or gaps in any part of your home let out air. Checking your home for leaks is a great way to bring down the cost of your monthly electrical bill.
Common Air Leak Locations
It is easy to notice when there is an air leak coming from your door or window. All you have to do is put your hand next to them on a windy day and you will know if air is leaking out. Not all air leaks are so accessible however, and many can be difficult to locate. Just because you don’t notice them doesn’t mean they aren’t costing you money. Some places you should check for air leaks include:
- Plumbing vents
- Basement rim joists
- Behind attic knee walls
- Recessed lights
- Electrical outlets
- Electrical boxes
- Air ducts
Test for Leaks
While in many cases you can just feel the air leaks by standing near them, this is not always the best way to located leaks. Some leaks you never go near and others are so small you may not notice them. For a more accurate check, use a lit incense stick or smoke pen. On a windy day, hold either of these next to the possible air leak. If the smoke blows sideways, then there is a leak.
How to Fix a Leak
Ductwork is delicate and precise, so it is important to contact an experienced HVAC technician to seal the leaks in your air ducts. However, sealing other household leaks yourself is easy and cost efficient.
Caulk will easily seal and fill gaps that are letting in air around your windows and doors. Purchase a caulking gun as well to evenly dispense the caulk. The caulk itself only costs around $2 a tube and the caulk gun is generally priced around $10.
Consider having your attic professionally air sealed and insulated for larger leaks. While it is possible to take care of some smaller attic leaks yourself, larger leaks can be difficult. Having the job professionally done will ensure it is done right, and you will no longer be wasting money.
