PROJECT SPOTLIGHT

Post-Renovation Duct Cleaning in Richardson

A single-story Richardson home coated in fine white drywall dust after a kitchen and living-room remodel. Because the home uses flexible ducting, the job called for a gentle, camera-guided cleaning that would not damage the lines.

How the job went

Every project, the same way: look, show, fix, prove.

01

The call

After the remodel, a chalky white film kept settling on the family’s new quartz counters and hardwood floors. The HVAC system had been left running during the final drywall sanding, so fine gypsum powder bypassed the filter and coated the inside of the flexible supply lines.

02

What the camera found

Drywall dust is highly abrasive. Beyond the ducts, it had worked into the blower and settled on the fine aluminum fins of the evaporator coil, where it acts as an insulating layer that chokes cooling, forces longer run cycles, and puts extra strain on the compressor during North Texas summers.

03

The work

Flexible ducting is a thin liner over a wire helix, so rigid metal brushes were off the table. We mapped the runs with a fiber-optic duct camera, then used ultra-soft nylon spinning brushes on flexible rods that expand gently to the pipe diameter and loosen the gypsum from the ribbed liner without stressing the wire frame. We tapped our dual-HEPA negative-air system into the return plenum to pull the fine powder straight out of the house, then hand-cleaned the blower wheel, cabinet, and coil.

04

The result

Every trace of gypsum was cleared from the flexible ductwork and furnace cabinet, and cleaning the coil brought the system’s temperature split back to its normal range. The recurring white film on the home’s surfaces was gone, and the family could finally enjoy the remodel.

Questions about this job

What homeowners ask when they see a project like this one , answered straight.

Why is drywall dust such a problem for my HVAC system?

Drywall dust is fine and abrasive. It coats the evaporator coil and works into the blower, which chokes cooling and forces the system to run longer, so it needs to be removed properly.

Yes. Flexible ducts are a thin liner over a wire frame, so we use soft nylon brushes and camera guidance instead of rigid metal tools that would tear the lining.

It should. Once the gypsum powder is pulled out of the ducts, coil, and blower, there is no longer a hidden source pushing it back into the rooms.

As soon as the dust settles. The sooner it comes out, the less it works into the coil and blower where it does the most harm.

Both. On a job like this we hand-clean the blower wheel, cabinet, and coil, since that is where the fine dust does the real damage.
