Admiral, King County
Air duct cleaning in Admiral is priced from $535. Above that base, the price moves with how many registers you have, whether there is a second furnace, and how hard the main trunks are to get at. The house is put under suction from a large vacuum at the furnace, then each run is brushed or air-whipped toward it so dust travels into the collector and not into the rooms.

Not every Admiral home has ducts. In the Census ZIP code area covering this neighborhood, Alki, Genesee and north Seaview, electricity is the main heat for about 61.3% of occupied homes, utility gas for about 31.3% and fuel oil for about 4.7%. Baseboard and wall heaters need no ductwork. Furnaces do, whether they burn gas or oil, and an older furnace system may have decades of dust in its returns. We confirm what you have on the phone before quoting.
Every air duct cleaning we do in Admiral includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowReturn ducts collect the most: household dust, pet hair, construction debris left from a remodel. Supply ducts stay cleaner but gather fine dust at each boot. The regional air agency's 2024 summary reported no wildfire smoke that year, with its fine-particle health goal exceeded on a few winter days because of wood smoke. On days like those, whatever is in the air outdoors ends up in the return side of a forced-air system.
Registers are counted and the trunk lines traced so no branch is skipped.
The collector connects near the furnace and pulls the ductwork below room pressure.
With other registers covered, one run at a time is agitated from the room end back to the trunk.
Main lines are whipped through access openings, then the blower compartment is vacuumed.
Openings get screwed metal covers, registers go back, and you are shown what was collected.
Cleaning sometimes turns up a duct that has come apart or was crushed. For repairs of that size, the residential exemption list (R105.2) is the text to read: it exempts small repair or alteration work whose total value over six months stays within the threshold the section names, provided no loadbearing support is removed, reduced, altered or relocated. Seattle's adoption page confirms that these 2021 rules stay in force until the 2024 codes arrive, which the city puts at May 2027 or later.
Reconnecting a fallen run or replacing a short damaged section normally fits that description. Adding new runs or relocating equipment does not sound like it, and the same list warns that mechanical permits can apply on their own terms. If an Admiral job points that way, we stop at cleaning and tell you what to ask SDCI.
