Swannanoa's valley position along the Swannanoa River makes it susceptible to morning fog and cold air pooling. The community's recovery from recent storm damage has increased demand for complete HVAC system replacements as homes are rebuilt or renovated. Many Grovemont-area homes built in the 1940s–60s have undersized ductwork that restricts airflow and reduces system efficiency.

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.
