Quick answerAir duct cleaning in Spokane uses a truck or portable vacuum to put the duct system under negative pressure while brushes and air whips loosen dust and debris from every supply and return run. A typical house takes three to five hours. It makes the most sense after a remodel, heavy smoke exposure, pests or visible buildup at the registers.

When duct cleaning is worth doing
We clean ducts when there is a reason to: drywall dust after a remodel, visible buildup on the return grille, pet hair and dander in a newly bought house, signs of rodents, or a smoky smell that returns every time the furnace runs. Without a trigger like that, a good filter usually matters more.
The job is only as good as the containment. We seal off the registers, connect a vacuum to the main trunk so everything loosened is pulled out of the house, and clean the returns, supplies, blower compartment and the coil surface we can reach. Then we fit a fresh filter so the system does not reload itself.
Duct cleaning jobs we handle
Post-smoke duct cleaning
After a heavy smoke season, fine particles settle on duct walls, the blower wheel and the filter rack, and the smell can come back each time the system starts. We clean the full supply and return system under negative air, pay particular attention to the return side where smoke enters, and clean the blower wheel because smoke residue sticks to its blades. We also recommend a higher-grade media filter going forward, since the next smoke season will load the ducts the same way.
Dryer vent cleaning
A clogged dryer vent is a fire hazard and makes every load take longer. Lint builds up in the long runs that older homes and upstairs laundry rooms use, and in vents with crushed or foil flex sections. We brush and vacuum the full run from the dryer to the exterior hood, clear the hood's flap, and replace crushed flex with smooth rigid duct where needed. If the run is longer than the dryer manufacturer allows, we tell you and explain the options.
Pre-move-in cleaning
A house that sat empty, housed pets or went through a renovation before you bought it can carry years of someone else's dust in the ducts. Cleaning before you move furniture in is the easiest time, because every register is reachable and nothing needs moving. We inspect with a camera first, clean supply and return runs, check for rodent activity or damage, and replace the filter. If the camera shows the ducts are clean, we say so and skip the job.

Smoke seasons in Spokane and the Okanogan
In August 2026 homes across Spokane and Spokane Valley sat in smoke from the Old Trails, Autumn Lane and Fairview fires, and Omak, where our head office sits, sees its own heavy smoke periods from wildfires in the Okanogan. A furnace or AC that ran through those weeks with a basic filter pulled smoke through the returns, which is when we see the most requests for duct and blower cleaning.
