HVAC Duct Sealing

Sealing your ductwork can lower your cooling and heating bill by up to 25% or more!

HVAC Duct Sealing & Repair

25% to 40% of HVAC energy output is lost through duct systems. Sealing ductwork is DE’s top priority in improving energy efficiency and comfort.

Countless studies prove that a duct leakage test is one of the most crucial aspects in determining the energy efficiency, energy costs, moisture problems, and health and safety concerns in the home. Our goal is to reduce duct leakage as much as possible. Unfortunately, a recent study by a highly respected national laboratory found that a 25% loss of efficiency due to ductwork issues is typical.

Why Does Duct Sealing Matter?

The reason sealing leaky ducts is such a priority for us across the Gulf South is simple. Due to pressure imbalances, the amount of conditioned air that is leaking out of a building’s ducts will inevitably be replaced by the intrusion of the same amount of extreme (hot/humid) outside air. If the ductwork leakage is excessive the result can be extreme humidity levels in the home, buckling sub-floors, condensation around ceiling vents, mold/mildew, and water-saturated attic insulation/sheetrock, among other issues.

Having your duct-work properly sealed is one of the home energy efficiency improvements with the fastest, highest and longest paybacks. Airtight ductwork can save up to 25% or more on your cooling and heating bills. These savings will go on for many years, providing ongoing savings that pay off in multiple ways – You keep more money in your pocket. Your HVAC equipment will last longer and operate more efficiently. And, you will enjoy increased comfort and improved indoor air quality [IAQ].
