Air duct cleaning for Seattle homes
Seattle has every kind of house, from Craftsman homes and bungalows in Ballard, Wallingford and Queen Anne to mid-century ramblers in Lake City and West Seattle, plus newer townhomes all over the city. In a lot of older homes the ductwork is decades older than the furnace or heat pump it is hooked to.
From October to May the windows stay shut and the heat runs most days, so the same air goes through those ducts over and over. Spring brings tree pollen, and some summers bring wildfire smoke. Dust, pet hair and pollen settle in the returns and trunk lines and get pushed back out every time the system kicks on.
Condo or townhome? If your home has its own furnace or air handler with ducts, we can clean it.
Since 2019, we have cleaned the air ducts in 2,945 Seattle homes.
Step by step at your Seattle home
- Floors get covered and doorways and wall corners get guards before any equipment comes in.
- A 10″ hose runs from our truck to your main trunk line, and the truck-mounted HyperVac pulls 12,000 CFM.
- Each supply line is scrubbed with soft high-pressure air tools that push the dust back to the trunk.
- Returns, trunk lines and the plenum are cleaned as well, and you get before & after photos by email.

“Jesus was professional, communicative, and attentive to small details. He took the time to explain to us what he was doing and educate us about air ducts and their maintenance.”

“Jesus from Alpine did an exceptional job with the cleaning of our heat ducts. He walked us through the process before he got started and answered any questions that I had. He kept everything clean and orderly during the process and when he was done walked us through the results and made recommendations for maintaining for the future. Thanks Jesus!”

“The Alpine team was efficient, effective, on time, and extremely professional. The work that their team does is inherently a little bit dirty, but they didn’t leave a trace behind by the time they had left. This is the second time that I have used them for duct cleaning, and it certainly will not be the last!”

“Very grateful for Alpine’s service. Our ducts were in bad shape and needed a serious deep clean. Steve was very thorough and took his time to do the best precision cleaning! He was also very friendly and personable. We’re very happy with our experience.”

Common questions from Seattle homeowners
What does air duct cleaning cost in Seattle? It starts at $474.95 for a home up to 1,500 sq ft ($75 off already applied, through December 31, 2026), plus sales tax. Bigger homes are priced by square footage, and you get the number in writing before we start.
Can you clean the ducts in an older Seattle home? Yes. We clean the supply runs, the cold-air returns, the trunk lines and the plenum, and we email you before & after photos so you can see what came out. If your tech sees anything that would add to the price, they walk you through it before any work starts.
We have a second furnace upstairs. Can you do both? Yes, in the same visit. Each additional furnace or air handler is $99.95 and shows on your written quote before we start.
How do you keep the dust out of the house? Floors, doorways and wall corners are covered before we start, and a powerful air scrubber runs while we work, filtering the air and capturing the dust that gets stirred up. The dust from your ducts goes out through the hose to the truck, not into your rooms.
Can you do our dryer vent too? Yes. Add it to your air duct cleaning for $99.95 and we do both in the same visit.
