Real work

Replacing a failed attic supply plenum

Fort Worth, TX, October 2026

Why they needed it

The supply plenum is the box on the air handler that feeds every supply duct. This one was fiberglass duct board, and its seam at the air handler collar had pulled completely apart, with the old foil tape and mastic split open. The lower seam had torn too, tight against the framing and the attic decking, so cooled air was blowing straight into the attic. A system in that state runs longer, cools the far rooms poorly, and pulls hot attic air into the house.

What we did

Disconnected the air handler from its power and control wiring, the overflow float switch and the condensate line, and shifted it on its platform to reach the whole collar. Tore out the failed duct board plenum and installed a new insulated 26-gauge sheet metal supply plenum with new start collars. Screwed it to the air handler flange every 4 inches, hung it and its take-offs on their own straps, and sealed every seam, collar and flange with fiberglass mesh and a continuous coat of duct mastic. Reconnected the system and checked static pressure.

About the price on this job: The starting prices on the AC repair page are for repair parts. This job was a different kind of work: the air handler was disconnected and shifted, and the duct board plenum was replaced with an insulated sheet metal one, then screwed, strapped and sealed. Plenum work is quoted in writing after a look in the attic, before any work starts.

FAQ

Common AC repair questions.

A system that runs without cooling usually points at the outdoor unit rather than the thermostat. A failed capacitor or contactor stops the compressor or condenser fan from starting, and a failed condenser fan motor lets the system run while shedding no heat. All three are separate repairs with their own starting price, so a diagnosis tells you which one applies.
No. The ECM blower motor price is all-inclusive and covers programming and calibration. There is no separate fee for it.
