Ductwork & Crawl Spaces · Greensboro, NC

Ductwork & Crawl Space HVAC in Greensboro, NC

In many Greensboro homes, the ducts run through a vented crawl space or a hot attic. Leaks there pull in damp air and send cooled air into the dirt.

Signs of duct trouble

Rooms that never cool, high bills, dust and a musty smell when the system runs.

Disconnected runs

Ducts under houses can come loose or be crushed.

Leaky joints

Sealing joints with mastic cuts losses.

Insulation

Uninsulated ducts in a crawl space sweat in summer.

Moisture

Damp crawl spaces can lead to mold on ducts and framing.

Encapsulation

Some homeowners seal and condition the crawl space; ask about the trade-offs.

Balancing

Dampers adjust airflow between rooms.

New ducts

Badly damaged ductwork is replaced.
