Patch Up & Wrap Up Air Ducts for a More Affordable Furnace Season

Posted on October 19, 2015 by Chris Lancaster

Insulate Air DuctsThe air ducts are the single biggest energy wasters in your home. This also means they are wasting a lot of your money in  heating and cooling bills every month. By sealing and insulating them, you can improve their efficiency by 20% or even more. Here’s how to figure out if your ducts are performing poorly, and how to get started sealing and insulating them now so you’re more comfortable once the cooler weather sets into Kansas City for good.

Signs Your Ducts Are Performing Poorly

Do you experience some of these telltale signs of poorly performing air ducts?:

  • you have rooms that are difficult to heat and cool

  • you have high summer and winter utility bills

  • you have stuffy rooms that never seem to feel comfortable

  • you find tangled or kinked flexible ducts in your system

  • your ducts are located in an attic, crawlspace, or the garage

How to Seal Your Ducts Correctly

Start off by using the correct materials to seal your air ducts. The best product to use is mastic sealant or metal tape. Do not, we repeat, DO NOT use duct tape. Check all of the ducts that you can access, such as those in attics, crawlspaces, unfinished basements, and garages, and seal those first – those are the places where they are most vulnerable. Then, check that the connections at the vents and registers are well sealed where they meet the floors, walls, and ceiling. These are also spots where leaks and disconnections are often found.

Insulate Your Ducts Where They Need It Most

Hit spots in attics, crawlspaces, unfinished basements, and garages first where air ducts are most likely to experience temperature differences. Use a foil-faced fiberglass insulation with an R-6 or higher insulation value. Seal with metallic foil duct tape to hold the insulation in place. Check the foil surface of the insulation and make sure it is free of dust before applying the tape.

If you’ve tried sealing and insulating your air ducts and don’t see a difference in your heating and cooling bills, it might be time to install a new furnace system.
