Fremont, King County
Air duct cleaning in Fremont starts at $525. The floor price is a compact forced-air system: one furnace, a modest number of supply registers, returns that are easy to open. Count of registers, number of levels and how the trunk lines can be reached are what raise it; a house with ducts in both a crawl space and an attic takes longer than one with everything in an open basement. First comes a tally of registers and a look inside the furnace cabinet; the figure quoted after that tally is the figure billed.

Only some Fremont homes have ducts at all. In ZIP area 98103, the Census area Fremont sits in, electricity carries the heating load in 56.7 percent of occupied homes, and electric heat can mean baseboards or wall units with no ductwork. Utility gas, the usual fuel of a forced-air furnace, leads in 39.6 percent, and fuel oil hangs on in about 350 households. Since the median home there dates from 1970 while more than a third were standing before 1940, duct systems in the area can be original to a recent building or fitted into a much older house long after it was built. We never assume a layout from the address.
Every air duct cleaning we do in Fremont includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowDucts in an older house tend to collect three things: construction dust from each remodel, debris that fell through floor registers, and whatever the return side pulled from a basement or crawl space. Smoke adds a seasonal layer. Wildfire smoke on a scale the region had not known has marked the period from 2015 on, the Clean Air Agency writes, while noting that 2024 brought none. Its advice for a smoky spell: a HEPA unit, or, as a homemade substitute, a MERV-13 panel fixed over the intake of a plain box fan, with the fresh-air intake shut. Clean ducts and a fresh filter are the part of that advice a forced-air household can prepare ahead of the season.
We locate every register, return and trunk, and find where the collector can be connected.
Registers are covered and the vacuum draws the whole network toward one point.
Compressed-air tools drive dust from the far end of every run into the airstream.
Access holes are patched to be airtight and you see the interior photos.

Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
We clean the blower compartment and the plenums as part of the duct system. Burner service and heat exchanger work belong to a furnace technician; SDCI requires a permit to replace or alter a furnace in this city, and we stay on the air side.
No. Without ducts there is nothing to clean, and we will say so on the phone instead of booking a visit.
No. That fee, $99 plus tax, concerns chimney inspections and is set against chimney work a customer approves. Duct cleaning is priced on its own after we count the registers.
