Air Duct Repair in Lenexa, KS

Air duct repair in Lenexa homes

One room stays hot. A register barely breathes. You hear a whistle near the furnace, or you smell basement every time the blower starts. Those are duct faults, not equipment faults. A new condenser will not fix any of them.

In pre-1985 homes the trunk and branch is galvanized sheet metal in the basement ceiling, with round pipe and crimped takeoffs. Takeoffs work loose. Joints open at the seam. Panned floor-joist returns are the worst offender here, because the joist cavity itself is the duct. Framing gaps pull dust, insulation fiber and basement moisture straight into return air. Repair means sealing the pan edges and the rim, not cleaning it.

Newer builds run R-6 or R-8 flex off sheet metal plenums, often through unconditioned attics. Summer attic temps reach 130–150°F up there. Flex gets crushed under stored boxes, kinked at tight turns, or sags between supports until airflow dies. Boots sweat and stain ceilings. Fixes are re-supporting, shortening runs, and resealing the boot collar.

Crawlspace runs on the rural edge of town wick moisture from exposed soil. Sealing duct there without addressing ground cover buys you a year, maybe two.

We inspect first, then tell you which sections are worth saving and which should be replaced outright.
