Places to Check for Leaking Air Prior to Furnace Service in Your St. Louis Home

October 21, 2015

As you get ready for your annual furnace maintenance this year, take a minute to consider breaking down the amount that you spend on heating and cooling throughout the year. Then, think about the last time you’ve taken a walk around and searched for leaky doors and windows. It’s something that practically all homes have to put up with, but there is a significant portion of money slipping between the cracks, going out the window – literally. 

However, the majority of the cracks and leaks can be easily handled on your own, helping you save money year-round. Plus, it can help you increase the bonuses of your annual furnace service too, helping you potentially hold on to more heat while helping to boost energy efficiency and your comfort. 

So where should you check for those irritating leaks? 

The attic.

Attics are well-known for allowing the most air out of your home, so view these specific areas while up in your attic:

  • Stud cavities around your home can be open, or uninsulated, meaning air can easily leak out, leaving you with a less-than-comfortable home and greatly diminishing your energy efficiency as well. If you are wanting to get the most out of your annual furnace service, make sure you fill these cavities to better insulate your home.
  • Recessed lights typically have vents that open in to the attic, which leaves the door open for heat loss. Make sure your lights come already sealed or add an airtight baffle to solve 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 get in to your attic.

All house openings.

Windows and doors are usually the key culprits for lost heat, and rightfully so.

  • Check to make sure the weatherstripping on all of your doors is in working order and isn’t cracked or torn. If it is, replace it.
  • Check the border 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 openings you notice.
  • If your home has a chimney, make sure any gaps around the flue or chimney itself are properly covered with aluminum flashing to inhibit air flow.

The number of ways you can get the most out of your annual furnace service dollars is awfully long, but if you take a little time to tackle the recommendations we’ve outlined, you can probably make your home more efficient and more comfortable.
