Crawl Space Ductwork in Triad Homes
Short answer: ducts in vented crawl spaces sit in damp, unconditioned air. Leaks pull that air in and waste cooled air. Sealing, insulating and sometimes encapsulating the crawl space improve comfort and efficiency.
Request an AC technicianWhy it matters
Leaky ducts can waste a large share of conditioned air.
Sweating ducts
Cold ducts in humid air drip water onto insulation and framing.
Disconnected runs
Pests, storage and age can knock ducts loose.
Sealing
Mastic and proper tape seal joints.
Insulation
Wrap ducts to prevent sweating.
Vapor barriers
A ground cover reduces moisture.
Encapsulation
A sealed, conditioned crawl space keeps ducts in drier air.
Mold
Musty smells may mean mold under the house.
Inspection
A contractor can crawl and inspect.
Testing
Duct testing measures leakage.
Rodents
Animals chew through flexible duct; seal crawl space openings.
