Leaky ducts waste air you have already heated or cooled and can pull dusty attic air into the house. We inspect the runs, reconnect and seal joints, replace damaged sections and check that each register gets the airflow it should.

Attic Ducts in Ranch Homes and Crawl Spaces in Bungalows

Post-war ranch tracts in Clairemont, Bay Park and Allied Gardens usually have flexible ducts snaking through the attic from a furnace in the hall closet or garage. Years of summer attic heat break down the duct jacket and tape, and joints pull apart, so cooled air spills into the attic instead of the bedrooms. Older raised-foundation bungalows in North Park and Mission Hills may have ducts in the crawl space, where rodents and moisture do their own damage. In two-story homes in Eastlake and Otay Ranch, long runs to upstairs rooms often explain hot spots.

Air Duct Repair FAQ for San Diego, CA

How do I know if my ducts are leaking?

Signs include rooms that are hard to cool or heat, weak airflow at some registers, a dusty house and energy bills that keep climbing. We inspect the duct runs and connections and show you what we find.

Can crushed ducts cause my AC to freeze up?

Yes. When ducts are crushed, kinked or blocked, the system can't move enough air across the indoor coil, and the coil can get cold enough to ice over. Repairing the duct often fixes the freezing and helps the AC cool better.

Do you repair ducts in crawl spaces?

Yes. We repair ducts under raised-foundation homes as well as in attics and garages, and we look for rodent damage and moisture while we're down there.
