Air Duct Cleaning: The Full Process Explained

Before any equipment runs, the crew walks the home, identifies every supply and return, and lays down floor protection from the door to the air handler.

The system is put under negative pressure with a HEPA-filtered vacuum. Then each individual run is agitated with brushes or compressed-air whips so the debris pulls toward the vacuum rather than scattering into the home.

A real cleaning includes the evaporator coil and the blower wheel — that's where most of the residue sits. The job finishes with a fresh high-MERV filter and before/after photos of every component cleaned.
