Bothell, King County
Air duct cleaning in Bothell starts at $525 for a whole-house system. Vent count, run length and how easily we can reach the furnace and trunk lines decide where a given house lands above that. We put the system under negative pressure, agitate the dust loose from every run and pull it out through a sealed collection unit, so none of it lands back in the house.

Per Census estimates, utility gas is the main heat in roughly 46.5 percent of Bothell's occupied homes and electricity in about 51 percent. Wherever that heat travels through a forced-air system, the same ducts move air year after year, and they carry whatever the house breathes in: dust, pet hair, construction debris after a remodel, and smoke on bad air days.
Burn bans exist because wood smoke builds up on still winter days. Home wood heating, according to Puget Sound Clean Air Agency's 2024 numbers, drove fine-particle readings past the agency's health target on up to four winter days, up from a maximum of three in 2023.
For Snohomish County, which takes in north Bothell, the agency counted 261 good days, 105 moderate and none unhealthy in 2024. The good days far outnumber the bad, but a forced-air system recirculates what gets inside during the few bad ones, which is one reason clean ducts and a good filter matter.
Every air duct cleaning we do in Bothell includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe requests we get most are after a remodel, when drywall dust has gone into the returns, after buying a place where nobody remembers the ducts being opened, and after a summer of smoky weeks. We also see return grilles and filter slots packed with debris, which starves the furnace of air and makes the rest of the system work harder.
WeatherSpark finds muggy conditions essentially absent from Bothell's year, yet the winter air is anything but dry. The Western Regional Climate Center reports that in the inland valleys west of the Cascades, a January morning sits near 87 percent humidity and the afternoon only dips to about 78.
Damp outdoor air is pulled into the house every time a door opens or a return draws from a crawl space or garage. Where ducts run through those cool spaces, dust in them can hold moisture and start to smell; cleaning removes the dust that gives the smell something to cling to.
We locate every supply and return, the trunk lines and the furnace, and note anything blocked or disconnected.
The collection unit is connected and the ducts are put under negative pressure before any cleaning starts.
Each run gets agitated with brushes and compressed-air whips, while the registers are scrubbed and put back.
The blower area is vacuumed, a fresh filter goes in and the photos we took inside the ducts are yours to keep.

It starts at $525 for a whole-house system. Larger homes, more vents, long runs or hard-to-reach trunks raise the price, and the quote shows the count before we start.
Clean ducts help the filter do its job, but the Puget Sound Clean Air Agency's advice for smoky days is a HEPA filter and a closed clean-air room. We can clean the ducts before the season so they start clear.
There is no fixed interval. Good triggers are drywall work, a newly purchased older home, or debris you can see in the registers.
