Air Duct Cleaning in Preston Hollow, Dallas — Dust in Every Run We Opened

Bloom Air Duct Cleaning completed an air duct cleaning at a home in Preston Hollow, Dallas. We opened several duct runs during the inspection, and every one of them had the same problem: a coat of dust spread across the foil liner, settled into the folds all the way down the line.

What We Found

The first run was a foil flex duct with dust lying in every crease. In the photo at the top of this page you can see how the dust sits on the high points of the crinkled liner, which is exactly where moving air picks it up and carries it back into the rooms.

The second run looked the same, with a heavier layer near the opening:

The third was a smoother duct with a thick tan layer covering the walls, the kind of buildup that takes years to form:

How We Cleaned the System

We cleaned the whole system, not just the runs in the photos. A negative-air machine with a HEPA filter was connected to pull air through the ductwork, and each line was cleaned with rotary brushes and air whips while the machine carried the loosened dust out. Registers stay covered until their line is done, so the dust goes to the machine instead of the living room.

The homeowner received the before and after photos from inside their own ducts, the same ones shown on this page.

Why Larger Preston Hollow Homes Build Up More Dust

Preston Hollow homes tend to be large, often with long duct runs and more than one HVAC system. More ductwork means more surface for dust to settle on, and a system that runs most of the year in the Dallas heat keeps moving that dust around. Big trees and landscaped yards add pollen and outdoor dust that the return vent pulls in.

That is why we look at every system, not just one. If your home has two or three HVAC units, ask us to check each one during the visit.
