The Hidden Energy Waste in Your Home

According to the Department of Energy, the average home loses 20-30% of its conditioned air through leaky ductwork. That means up to a third of what you're paying to heat and cool your home is being dumped into your attic, crawl space, or wall cavities — spaces you're not trying to condition. In Western North Carolina, where heating and cooling costs are significant, duct sealing is one of the highest-return energy improvements you can make.

Professional Sealing vs. Duct Tape

Despite its name, duct tape is terrible for sealing ducts — it deteriorates quickly in the hot and cold environments where ductwork runs. Professional duct sealing uses mastic sealant (a thick, durable adhesive) and UL-listed foil tape at all joints, connections, and boot connections. We seal the duct system from the inside where accessible, focusing on the highest-leakage points: supply and return plenums, branch takeoffs, register boots, and the air handler cabinet.

Measurable Results

After sealing, we can perform a duct leak test to verify the improvement. Most homeowners notice the difference immediately — rooms that were always too hot or too cold become comfortable, the system cycles less frequently, and energy bills drop. Duct sealing pairs perfectly with a maintenance tune-up or a ductwork evaluation as part of a whole-house efficiency upgrade.
