The Energy Drain Hiding in Your Walls and Attic

The Department of Energy reports that the average home loses 20 to 30 percent of its conditioned air through leaky ducts. That can mean a full third of your heating and cooling dollars is being dumped into the attic, crawl space, or wall cavities — areas you are not trying to condition. In Western North Carolina, where utility costs for heating and cooling are substantial, duct sealing ranks among the highest-return energy improvements available.

Why Duct Tape Fails and Professional Sealing Succeeds

Its name notwithstanding, duct tape is a poor choice for sealing ductwork — it breaks down quickly in the temperature extremes where ducts run. Professional duct sealing relies on mastic sealant, a thick and durable adhesive, along with UL-listed foil tape applied at every joint, connection, and boot. We seal the system from the inside wherever accessible, concentrating on the biggest leak sources: supply and return plenums, branch takeoffs, register boots, and the air handler cabinet itself.

Results You Can Measure

Once sealing is complete, we can run a duct leak test to quantify the improvement. Most homeowners feel the difference immediately — previously uncomfortable rooms reach the right temperature, the system cycles less often, and energy bills decline. Duct sealing pairs naturally with a maintenance tune-up or a full ductwork evaluation as part of a whole-house efficiency upgrade.

HVAC Challenges in Asheville

Asheville's mix of historic homes in Montford and North Asheville — many built before central HVAC existed — creates unique retrofit challenges. These older homes often have limited ductwork space, uneven heating across floors, and single-pane windows that strain heating systems. Meanwhile, newer South Asheville construction demands properly sized high-efficiency systems to handle the area's 4,400+ heating degree days per year.

Seasonal Tip for Asheville Homeowners

Asheville's elevation means nighttime temperatures can drop into the 20s even in early spring. We recommend keeping your heating system serviced through April and scheduling AC maintenance by mid-May to prepare for the humidity that builds through summer.
