Air Duct Sealing
Are Your Ducts in a Row?
When is the last time that your air conditioning ducts have been checked for leaky connections, rodent damage, or kinks restricting proper air flow? Unfortunately, your air ducts are often out of sight either in the attic or under the house and don’t get the proper attention. We recommend a duct inspection at least once every year (so does NADCA).
We can tell you this; the duct system has a very critical part in the proper operation of your “home as a system” even though your duct system is “outta sight & outta mind.” When you purchase a new A/C system you want it to last as long as possible & you want to get maximum performance out of the system as well.
Facts about A/C and Heating Duct Leaks
Typical unsealed duct systems lose up to
Heating or Cooling Capacity
Leaky ducts make your HVAC system (Heating, Ventilation, Air Conditioning) have to work much harder
Leaks in your ducts equals higher utility bills
Duct leakage can potentially cause dust, mold, and health issues. Major leaks can be found around joints at ductwork connections, around the air handler, and near vents. Look for holes, tears, and loose joints.
Every unsealed joint is likely a small leak—even if a gap is not visible.
The Secret to a Long Life For Your A/C System!
The secret is to have a Sealed Duct System with documented test numbers – not a guess or a quick peek. Test the ducts & make sure that you are going the get all the performance you expect out of your new A/C equipment. The test is called a “Blower Door” test or “Duct Leakage” test; some people use the term “Duct Blaster“ test. Ask about the ‘Gulf Power Check Me program’ for duct sealing & an instant rebate provided through the utility company when you have your duct system sealed.
Since most duct work is located in attics or crawl spaces, the conditioned air that you paid for never gets into the house. Leaking supply ducts (where the A/C system blows air) can lose large amounts of cooled/heated air to these unconditioned areas. Leaking return ducts (where the A/C system sucks air in) can suck hot, cold, or dusty air into the conditioned space. Duct leakage significantly increases cooling and heating loads, sometimes beyond what the HVAC system can handle.
