Air duct cleaning for Issaquah homes
Issaquah homes range from older houses around Olde Town and up Squak Mountain to the newer neighborhoods in the Issaquah Highlands, Talus and Montreux. Many of the newer homes are two and three stories, with long duct runs up to the bedrooms.
Between the forested hillsides, spring tree pollen and the occasional summer of wildfire smoke, a lot ends up in the returns. The furnace or heat pump then moves it from room to room.
How the visit goes
- Your price is confirmed before any work starts. If your tech sees anything that would add to it, they walk you through it first, and nothing is added without your okay.
- Slip-on shoe covers, floor tarps and plastic corner guards go down before our equipment comes in.
- Your tech cuts a small access port into the main trunk line, connects our 10″ truck hose and feeds high-pressure air tools down each vent line.
- The returns, trunk lines and plenum get cleaned too, and we email you before & after photos.
- The port is closed with a removable sheet-metal plate, screwed in place and sealed with foil tape made for ductwork.

“Wow. Got our ducts cleaner than I expected. After 40 years without any maintenance, I didn’t expect such a good result. The company and Anthony were excellent.”

Issaquah questions we hear a lot
What does air duct cleaning cost in Issaquah? 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.
We live in a newer home in the Highlands. Is it worth cleaning? Newer homes can hold construction dust in the duct runs and the returns, which is why we recommend cleaning sooner if you have had construction work. Text a photo of a register or two to 206-339-5684 and we will quote it before you book.
How often should we clean our ducts? Every 2 to 3 years is what we recommend. Clean sooner after construction work, smoke or pet issues, or if someone in the home has bad allergies.
Do you sanitize the ducts? We clean the duct runs mechanically with our truck system. No product is EPA-registered to sanitize the inside of ductwork, so we won’t claim that. What we do on Diamond is sanitize and disinfect every register and vent boot where most grime builds up.
Can you come on a Saturday or Sunday? Yes. Our duct crews work 7 days a week. The first appointment arrives between 8:00 and 8:30 am, and you get a text when your tech is on the way.
