Sammamish, King County
Duct cleaning is worth doing when there is something in the ducts, and not otherwise. That is our starting position, and we photograph the inside of your trunk lines before recommending anything. When the pictures show a mat of dust, construction debris or pet hair, cleaning the full system starts at $525. House size, the number of registers and how the ducts are reached set the final figure.

Two census numbers explain why the question comes up in Sammamish. Utility gas is the primary heating fuel in 72.1% of occupied homes, and where that gas feeds a furnace, the furnace moves air to every room through sheet-metal or flexible ductwork. And 12,121 of the city's housing units, about 53.6%, were built in the 1980s and 1990s. A duct system of that age has had thirty to forty-five heating seasons to collect what the filter missed, plus whatever was left inside when the house was built.
Every air duct cleaning we do in Sammamish includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWhat we find depends on the house's history. Drywall dust and sawdust in ducts that were open during construction or a remodel. Pet hair and dander packed at return grilles. Flexible ducts in the crawl space or attic that have sagged or come off their collars, so the system pulls unfiltered air. Occasionally evidence of rodents. A disconnected duct is a repair, not a cleaning, and we say so; cleaning a system that leaks at a joint just moves the dust.
We open a few registers and the main trunk, take pictures and show you. Clean ducts get a clean report and no sales pitch.
The vacuum is connected at the trunk, registers are covered, and floors and corners are protected.
Every supply and return run is worked toward the vacuum so loosened dust travels one way only.
Access openings are sealed, registers go back on, the filter is replaced and you get the after photos.
Smoke is a summer problem here. The Puget Sound Clean Air Agency ties wildfires to the hot, dry months, and the governor's emergency order of August 1, 2026 counted more than 1,000 fires across the state that year. In a house with forced air, the furnace fan and its filter are the largest air cleaner the household owns, if the filter is a good one and the return side is sealed.
Puget Sound Clean Air Agency's smoke guidance centers on filtration and on setting up a sealed clean room. Our part is narrower: we check that return ducts are connected and not drawing from the crawl space or garage, fit the filter the system can handle, and clean ducts that are carrying settled dust so the fan is not recirculating it. Sammamish's hazard annex, for its part, says the danger of wildfire west of the mountains is growing as droughts recur.

From $525 for a whole system. Larger homes with two furnaces or many registers cost more. The price is fixed in writing after we have looked inside the ducts, before any equipment comes off the truck.
No. It is condition-based. After construction work, after a rodent problem, or when photos show real accumulation, yes. A system that looks clean on camera can be left alone.
Filtration helps more. Clean-air officials for the Puget Sound counties point to a HEPA purifier or, as a low-cost option, a box fan carrying a MERV-13 filter. Cleaning removes what has already settled; the filter stops what is arriving.
