Air seepage happens when there are holes and cracks inside the house. When this occurs, electricity bills can soar as high as you hope they wouldn’t. To make matters worse, winters are expected to be colder than ever, and summers hotter even with the cooling systems turned on. Let us prevent excessive costs from burdening us by learning how to check for air leaks.
1. Use your eyes and skin to investigate for any failed caulking and gaps. Label these areas for later.
2. Close your doors and windows, turn any combustible devices off, and then open the bathroom and kitchen vents to allow outside air inside the house. This helps identify areas where there are cracks and openings.
3. Use an infrared thermometer, if you can afford one, to measure air temperature on windows and doors.
