Air Duct Replacement in Lenexa, KS

When duct replacement beats another cleaning

Pull a floor register and look down. If you see wood joist on three sides, that is a panned return. Lenexa's older ranches north of 87th are full of them. The joist cavity is the duct. Nails, drywall dust and insulation fiber sit in there. A brush cannot seal raw lumber. That run gets rebuilt in hard pipe.

Crawlspace trunk tells on itself from below. Look for rust blooms on the bottom seam. Soil moisture wicks up and eats metal from the underside first. Tape fails before the metal does. Fabric-backed tape turns to brittle ribbon and peels.

Attics change the math. Flex squashed under blown-in cellulose is throttled, not dirty. Check the dips. A long sagging belly holds condensate and sheds it onto the ceiling. Internally lined older duct sheds too; look for gray fuzz at the boot.

What moves the job is access and run count, not duct footage. A walkable attic with a center trunk is straightforward. A crawl with eighteen inches of clearance and ductwork over a sump is not. We will tell you plainly when cleaning buys you several more years. Replacing sound galvanized because a camera found dust is not work worth doing.
