Places to Check for Leaking Air Prior to Furnace Service in Your the Main Line Home10/21/2015 As you prep for your annual furnace maintenance this winter, take a second to consider calculating the amount that you spend on heating and cooling annually. Then, think about the last time you’ve walked around and checked for leaky doors and windows. It’s something that practically all homes have to deal with, but there is a large portion of money slipping between the cracks, going out the window – literally. However, most of the cracks and leaks can be easily taken care of on your own, helping you save money year-round. Plus, it can help you maximize the perks of your annual furnace service too, helping you potentially retain more heat while helping to increase energy efficiency and your comfort. So where should you check for those irritating leaks? The attic. Attics are known for allowing the most air out of your home, so look at these particular areas while up in your attic: Stud cavities around your home could be open, or uninsulated, meaning air can easily get out, leaving you with a less-than-comfortable home and considerably affecting your energy efficiency as well. If you are wanting to get the most out of your annual furnace service, make sure you fill these holes to better insulate your home. Recessed lights normally have vents that open in to the attic, which leaves the door open for heat loss. Make sure your lights come previously sealed or add an airtight baffle to take care of the problem on unsealed lights. Attic access doors usually aren’t thought of when you change or install weatherstripping to other windows or doors around your house but can let quite a bit of heat escape in to your attic. All house openings. Windows and doors are typically the main culprits for lost heat, and rightfully so. Check to make sure the weatherstripping on all of your doors is in working order and hasn’t been cracked or torn. If it is, replace it. Check the edge of all of your home’s windows, both in and outdoor, inspecting the caulking. It’s easy to use a caulking gun to plug any holes you find. If your home has a chimney, make sure any gaps around the flue or chimney itself are properly covered with aluminum flashing to prevent air flow. The number of ways you can get the most out of your annual furnace service dollars is pretty long, but if you take a little time to tackle the tips we’ve outlined, you can potentially make your home more efficient and more comfortable.
