The Junction, King County
Air duct cleaning in the Junction starts at $535. The number of supply and return registers, how many furnaces or air handlers the house has, and how easy the main trunks are to reach decide the rest. A powerful vacuum is connected at the trunk line so the whole system sits under negative pressure, and then each branch is brushed or whipped with compressed air so loosened dust travels toward the collector instead of into your rooms. Pictures taken inside the ductwork at the start and at the finish go into your report.

Postwar families filled the streets around the Junction. Southeast of the business district, Fairmount Park school opened on September 7, 1955 as rows of portables for 248 pupils and moved into a permanent brick building in fall 1964, HistoryLink records; Wikipedia places Fairmount Park along Fauntleroy Way between SW Edmunds and SW Graham streets. A house built in those years may still have much of the ductwork it was built with, and seventy winters of dust collect in places a filter never reaches.
Every air duct cleaning we do in The Junction includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowSmoke comes in from outside, too. In its data summary for 2024, the regional clean air agency counted a pair of July days when fireworks pushed fine particles past its health target, and as many as four winter days when chimney smoke did the same. Its advice for smoky spells is to set aside one room as a refuge and filter its air, using a HEPA cleaner, or failing that a box fan strapped to a MERV-13-grade (or better) furnace filter. A duct system full of old dust works against that effort every time the blower kicks on.
Registers are tallied, the trunks traced back to the furnace or air handler, and any damaged runs noted.
Floors and furniture near the registers are covered, and every register is sealed except the one being worked on.
The collector is connected at the trunk so dust moves toward it rather than out into the rooms.
Brushes and air whips work through every run, one register at a time, from the far end toward the trunk.
Registers go back clean, the blower area is vacuumed, and the system is run to confirm airflow.
Cleaning sometimes uncovers a duct that has separated at a joint or been crushed in a crawl space. Seattle's 2021 residential code, in the exemption list of section R105.2, lets minor repairs and alterations go ahead without a building permit when their combined value over six months stays below the code's ceiling and no load-bearing part is removed, cut, altered or moved. Reattaching or replacing a short section of duct normally fits that description.
The city's next code cycle is still pending (SDCI puts completion of the 2024 adoption at May 2027 at the earliest), so the 2021 editions remain the yardstick for this work. If a repair grows beyond a small fix, such as rerouting a trunk or adding a system, we ask SDCI about your address before quoting it.

The Junction is the commercial heart of West Seattle, named in 1907 when two streetcar lines met at California Avenue SW and SW Alaska Street, with brick and terra cotta storefronts from the 1910s and 1920s on California Avenue and residential blocks on every side. We work every part of it — the Alaska Junction included.

From $535. Registers, systems and how reachable the trunks are drive the total, and it is fixed in writing before any vacuum is switched on.
No. Baseboard heaters have no ducts. Only forced-air systems, from a furnace, heat pump or air handler, have ductwork to clean.
Most houses take a few hours. Larger homes with two systems can take most of a day.
They are priced apart. Ducts get their own quote; the chimney visit stays at $99 plus tax per stack.
