Beacon Hill, King County
Air duct cleaning on Beacon Hill is priced from $525 for a house with a single forced-air system. Your final figure depends on three things: register count, trunk length, and access to the furnace cabinet. A second system, or ductwork buried behind finished ceilings, adds time, and the quote says how much.

Ducts on the hill mostly serve gas or oil furnaces. In ZIP area 98108, which includes part of Beacon Hill, the Census Bureau's 2020–2024 estimates put utility gas as the main heat in 33.8% of occupied homes and fuel oil in 4.8%; in ZIP area 98144, at the north end of the ridge, the shares are 32.7% and 2.2%. Many of these furnaces sit in houses built long before them. The city's historic context statement dates most detached homes in the stretch from McClellan Street down to Jefferson Park to 1910–1929, and a furnace installed today is many replacements removed from the one the builder chose. On a house of that age we check whether the runs were added or rerouted after construction, and look for old gravity-furnace ducts left in place, joints taped instead of fastened, and returns that draw from an unfinished basement.
The cool season at Boeing Field, the weather station below the ridge, lasts about 3.7 months, from November 12 to March 2, in WeatherSpark's summary, with December lows averaging 37°F. A furnace on Beacon Hill runs through all of it, and with it the blower that pulls room air back through the returns. Each of those months adds to whatever has settled in the ducts.
Windows stay shut through most of that stretch. In a lowland winter month, the Western Regional Climate Center finds that between four and eight days have clear or partly cloudy sky, so houses are seldom aired out between November and March. We schedule duct cleaning before the heating season starts or right after it ends, so the system begins a winter with clean runs and a fresh filter.

Book nowThe commonest thing we pull out of a Beacon Hill return duct is fine drywall and sanding dust, left by renovation work done while the heat was running. The second is plain neglect of the filter, which lets the blower push lint and pet hair into every branch. Electric heat, the main fuel in 57.0% of homes in ZIP area 98108 by the same Census estimates, does not always mean no ducts: a heat pump moves air through them just the same, so the system type is checked before any quote is given.
We identify the system, count registers, and run a camera into the main supply and return so the quote reflects what is inside.
Registers are covered and a negative-air machine with HEPA filtration is attached to the trunk, so loosened debris is pulled away from the rooms.
Air whips and brushes travel each branch back to the main line, register by register, on both the supply and the return sides.
The blower compartment is vacuumed and the filter slot cleared. Anything that needs a heating technician, such as a dirty coil, is noted in the report.
Grilles go back after washing, a fresh filter goes in and the camera repeats its first shots for comparison.
