Air Duct Installation and Repair in Asheville, NC

Signs include rooms that never reach the thermostat setting, unusually high energy bills, dust buildup around vents, or a musty smell coming from vents connected to a crawl space or attic. A pressure test during a Bullman visit confirms exactly where air is escaping. Some leaks are obvious at a disconnected joint, while others only show up under testing.

Most duct sealing and repair work happens from the attic, crawl space, or basement where ductwork is exposed, not by cutting into finished walls. Bullman assesses access points during the initial visit and explains what the repair will involve before starting. Walls only come into play on rare jobs involving ducts fully enclosed in finished space.

Duct sealing closes gaps and reconnects loose joints on ductwork that is otherwise in good condition, while replacement is needed when sections are crushed, corroded, or too degraded to hold a seal. Bullman recommends the less invasive option whenever the existing ductwork can support it. A technician will show you the condition of the ducts before recommending either approach.

Sealed ducts stop conditioned air from escaping into unconditioned spaces, which means your furnace or AC does not have to work as hard to maintain the temperature you set. The amount of savings depends on how much leakage existed beforehand, since a system with minor leaks will see a smaller change than one with major gaps. A pressure test before and after the work gives you a direct comparison.

Yes, Bullman designs and installs new duct runs for additions, finished basements, and other spaces added to an existing home. The new ductwork is sized to match the load of the space being added, and connects into your existing system rather than requiring a separate unit in most cases. A technician will run a load calculation, meaning a measurement of the heating and cooling demand for that specific space, before finalizing the design.
