If your house has smelled like a campfire this summer, you're not imagining it. Wildfire season in the Inland Northwest means smoke doesn't just hang around outside - it works its way into your home through open doors, windows, vents, and every tiny gap in your building envelope. Once it's in, that smoky smell can linger for weeks if it isn't dealt with properly.
We get a lot of calls this time of year asking about air duct cleaning for smoke odor. It's a great service, but it's usually not the first thing you should do - and it's rarely the only thing you need. Here's the order that actually works.
Before You Call for Air Duct Cleaning, Start Here
Smoke odor doesn't just sit in your ductwork. It settles on nearly every surface in your home. Work through these four steps first:
1. Replace Your HVAC Filter
This is step one for a reason. A smoke-saturated filter will keep circulating that odor through your whole house every single time your system kicks on, no matter what else you clean. It's cheap, it's fast, and it stops the problem from spreading further while you tackle everything else.
2. Clean Surfaces
Walls, ceilings, cabinets, and other hard surfaces all hold onto smoke residue. It's not just a smell sitting on top - it's a fine particulate film that clings to surfaces and keeps releasing odor until it's actually cleaned off.
3. Clean Fabrics
Carpets, upholstery, curtains, and area rugs are some of the biggest smoke odor traps in a house. Fabric fibers absorb smoke easily and hold onto it stubbornly - this is usually where lingering odor is coming from even after everything else looks clean.
4. Use an Air Purifier
Run a quality air purifier with a HEPA filter if you have one. It won't undo smoke damage that's already settled into your surfaces, but it helps clear out what's still floating in the air while you work through the rest of the list.
Quick gut check: if you've replaced your filter and cleaned your surfaces and fabrics but the house still smells smoky, especially when the HVAC system is running, that's a strong sign the smoke made it into your ductwork.
Then Consider Air Duct Cleaning
Air duct cleaning is an excellent final step if smoke particles have made their way into your HVAC system. Once smoke gets pulled into the return air and travels through your ductwork, it can keep reintroducing that odor into your home long after the outside air has cleared, which is exactly why it's worth addressing directly.
Did you know? Air duct cleaning alone will not remove smoke odor if the residue is still on your walls, furniture, and carpets. The best results come from addressing the entire home, not just the ductwork. That's why we always recommend working through surfaces and fabrics first, then finishing with the ducts.

Most homes affected by wildfire smoke need more than one type of cleaning to fully clear the odor. A typical approach looks like this:
- HVAC filter: Replace immediately, don't wait
- Carpet and upholstery cleaning: Deep extraction cleaning to pull smoke residue out of fibers, not just mask it
- Air duct cleaning: Clears smoke particles and soot sitting in your ductwork so your system stops recirculating odor
- Air purifier: Ongoing support while everything else settles
