Testing HVAC Ductwork for Leaks Can Save Energy

Having the heating and cooling ductwork in your home tested for leaks, then repairing any leaks that are found, can reduce your heating and cooling bills significantly and save energy in your home. Watch this video to find out more.

Ever hear the saying, “What you don’t know can’t hurt you”? I can’t say I totally agree with that. A good example is if you have unknown leaks in your heating and cooling duct system, it can cost you a lot of money.

When you have leaks, it dumps expensive conditioned air into the attic and can pull outside air into the house, along with dust and mold spores. Having a duct test is one of the smartest things you can do.

These tests are very similar to the way a plumber can find leaks in the water pipes by pressurizing the duct work with a calibrated fan and measuring the air flow with precision gauges to determine how much air is leaking.

Once you know where the leaks are, it’s a simple matter of sealing the ducts properly with a special tape and mastic. And the cost for this test is insignificant compared to the energy and money you’ll save afterwards.

      It sounds like there is a leak somewhere in the ductwork.
      We recommend having a professional check it out.
      Good luck!
