Costly Culprits: Common Spots in Your Home that Leak Cold Air

Last updated 6 years ago

Cooling your home isn't cheap, and that's why every responsible homeowner knows the importance of properly insulating a home. It's the key to keeping your monthly utility bills low. Once you've insulated your home, however, it's still important to check regularly for leaks.

To get a sense of where air is flowing in your home, light a stick of incense in each room and watch the way that the smoke flows. You can also splash some water on your hand and move it around an area you suspect has a leak; this will make your skin more sensitive to the flow of air.

The most common leak spots in a house include:

Exterior windows and doors. When closed, a window or door should provide airtight resistance to the outside world. Even if you have had your doors and windows weather-stripped, you should still check them for uneven areas, cracks, and other leak sources.

Light fixtures. Recessed lights often ventilate into attics, making them a prime source of home air leaks. To insulate your light, buy an airtight bulb or install an airtight baffle cone into your fixture before inserting your bulb.

Electrical outlets. An outlet installed on an exterior wall of your home can provide air with a ready escape route from your home, and the more outlets you have, the more air you lose. If you find a leak in an outlet, have all of your outlets checked by an electrical contractor.

Attics. Attics are often the most ineffectively insulated part of your home, which means you should have any entrances to your attic weather-stripped or caulked to keep air from trickling out. Check all the plumbing pipes, light fixtures, outlets, and other likely leak sources in your attic.
