How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?
The fastest way to seal a leaking air duct is to have our team locate and seal the leaks during a professional duct inspection. We use specialized equipment and materials to reach hidden gaps that traditional methods can’t. Sealing keeps conditioned air in the ducts, improves comfort, and can cut energy bills by up to 20%. Leaky ductwork can reduce HVAC efficiency by up to 30%. Pair sealing with duct cleaning and IAQ testing for best results. Priority Plan members receive longer warranties.
