An important part of an energy-efficient AC system is a house that can keep the conditioned air in and the outside air out. Air leaks around your windows could be letting the air in your home draft out, costing you money and putting an extra strain on your AC. Here are some ways to detect window drafts – and the best solutions for fixing them.
Take A Closer Look
One of the easiest ways to detect a window leak is to inspect the windows visually. Check for damaged caulking around the windows outside your house, which indicates that the seal has failed. If you have single-paned windows, look for cracked or otherwise damaged glazing. (This is the putty that holds the glass in its place).
Inside the home, look for daylight through the window frame – and examine the weather stripping, making sure it’s in good shape. The Department of Energy recommends that you rattle windows to test for movement. If you can move the windows at all or can see daylight around the window frame, the window isn’t properly sealed.
Not all leaks are visible with just a visual inspection, so you might consider a building pressurization test or a smoke test. Begin by closing all windows and doors and turning off all combustion appliances, like a water heater or furnace. Then, turn on your kitchen and bathroom vents to create negative pressure in your house. This is so that air from outside enters through any leaks.
Check for drafts by lighting an incense stick and holding it around the window frames. If the smoke’s direction changes noticeably, wavering away from the window, there is a leak.
