Finding In-home Air Leaks

Home » Finding In-home Air Leaks

If you’re a resident of San Diego or the surrounding areas, it’s important to make sure your home is properly airtight. Air leaks in your house can cause you to slowly lose significant amounts of heat or cool air without your even knowing it, resulting not only in a potentially high bill payment but also an inefficient method of cooling or heating your home. With winter on its way out and spring just around the corner, both situations are a very real, continuous problem if you have not found and fixed air leaks in your home.

Where to Find Air Leaks

Air leaks can be found most commonly both in and outside the house wherever two types of construction components interact or the sealant or caulking has disintegrated. Typical leakage areas are around doors and window frames, but many other lesser known places can contribute. When checking for air leaks, be sure to inspect outlets and light switch covers, baseboards/molding and DSL/cable/phone cord hook-ups in the walls, anywhere fan covers or vents (dryer and otherwise) are inserted into the wall or ceiling, washing machine hoses, piping, ductwork, outside dryer venting or water spigots, and points at which outside siding, bricks, or stone meet. As you can see the various possible locations for air leaks seem endless, but short of hiring a professional a few tests you can perform yourself should help you find many of them.

How to Find Air Leaks

Besides physically checking by eyesight any of the locations mentioned above for cracks, gaps, or spaces needing to be filled, you can shine a flashlight over them to see if any light filters through a potentially weak area. Tiny leaks are best found after depressurizing your house. On a blustery, cooler day, after closing all outside doors, windows, and vents, and shutting off all air conditioning or heating to prevent any air circulation/movement, turn on any exhaust fans in your home to force inside air out-of-doors. Using a lit candle or incense, pass it slowly over any area of your home that might have developed leaking; any place the smoke is forced in or out of the room or house probably indicates a leak. You can purchase a specific air leak detector device which functions much the same way. For best results, hiring a professional specialist to perform a blower door test will provide you with complete, accurate results.
