Rooms Not Warming Up? 2 Steps To See If Your Ducts Are The Culprit

Do you have rooms in your home that just never quite reach the right temperature? Do they feel stuffy or uncomfortable? Are you constantly trying to adjust the vents to make sure that room gets warm enough? If you answered "yes" to those questions, you probably have some leaky ducts somewhere in your home. Leaky ducts can make it impossible for the air to make through your entire home. In fact, if you have leaky ducts, most of your heated or cooled air could be escaping before it even makes it into the house. Here are some simple tips that will help you find and repair those leaky ducts.

Finding Leaky Ducts

The only way you can find a leaky duct is to inspect all the ductwork in your home. If you're not sure where it is, you're going to find it in the attic and in the crawlspace. If you don't have a crawlspace under your home, all of your ductwork will be in your attic. Before you start inspecting your ducts, you'll need to grab a few supplies.

  • Gloves – to protect your hands from getting cut on sharp edges
  • Safety goggles – to prevent dirt, dust and insulation from getting in your eyes
  • Flashlight – to get a good look at your ducts
  • Permanent marker – to mark the spots where you find damage

Once you have your supplies, you'll be ready to inspect your ductwork. Beginning at one end, and working your way along the ducts, look for signs of cracks, slices or pinholes. Mark each damaged area you find so that you can come back and make the necessary repairs.

Repairing the Leaks

After you've inspected your ducts and identified all the problem spots, you'll be ready to make the necessary repairs. You're going to use either metal tape or mastic sealant. If you're using metal tape, wrap the damaged area with the tape to securely seal the leak. If you're applying mastic sealant, apply a thick layer of the sealant to each damaged area you find and allow it to dry thoroughly. Once the area is dry, apply a second coat of sealant.

If you're having a hard time heating each room in your home, you probably have a problem with your ducts. Use the tips provided above to take care of those problem areas. If you continue to have problems, you should have your heating technician like one from Allright Plumbing Heating & Air Conditioning come out and inspect your ducts.
