Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Cleaning Across Spokane
Air duct cleaning in Spokane typically costs $350-$650 for a complete residential system and is scheduled by appointment with a written price confirmed before any work begins. Most Spokane homes need cleaning every 3-5 years, though homes in wildfire-exposed areas or with older ductwork often benefit from more frequent service.
We’re the Air Duct Cleaning team at Kestrel, and we know Spokane’s ductwork inside and out. From the craftsman bungalows on the South Hill to the ranch homes spreading across Spokane Valley, we’ve cleaned systems in every neighborhood this basin has to offer. Our crews are dispatched from our Seattle coordination office, but they live and work in the Spokane metro, which means they understand why a January furnace failure or an August smoke event changes what your ducts need. Call (469) 972-3151 and you’ll reach a live person, any time of day, who can book your free estimate and give you a real arrival window.
Why Kestrel Air Duct Cleaning Is Spokane’s Preferred Air Duct Cleaning Company
We’ve been operating under the Kingswell Guarantee since 2004, and that same written standard applies to every Spokane job we do. The four promises never change: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if anything fails within the guarantee period.
Spokane homeowners call us back because we answer the phone. Not a queue, not a robot. A live person, 24/7. Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. They show up in the window we gave you, put the guarantee in writing, and leave the place cleaner than they found it. That’s The Kingswell Way.
Our 365-Day Done Right Promise is documented on every single job. If the work falls short within that year, we return and make it right at no charge. No courtesy extensions, no discretion. It’s in the paperwork you sign.
Residential Air Duct Cleaning in Spokane
Residential Air Duct Cleaning in Spokane means source removal of accumulated particulate from your entire forced-air system, not a surface wipe or a scented fog. In this market, we see two distinct housing stocks that need very different approaches: the pre-1950 craftsman and foursquare homes on the South Hill and in Browne’s Addition, and the 1955-1980 ranch tracts in Spokane Valley and north-side neighborhoods. A typical residential cleaning in Spokane runs $350-$650 for a full system, with older or larger homes sometimes reaching $750-$900 if access is limited or multiple returns need dedicated cleaning.
Supply and Return Duct Cleaning
We clean both sides of the loop. Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In Spokane’s wildfire-heavy summers, both sides load up with fine PM2.5 that bypasses standard filters. Our Nikro negative-air machines maintain suction throughout the job so loosened debris exits the system instead of settling in your living room.
Full System Cleaning with Video Inspection
We run a camera before and after so you see what was in there. No guesswork, no trust-me claims. The before-and-after footage belongs to you, and it’s the proof that the job was actually done.
Commercial Air Duct Cleaning in Spokane
Commercial Air Duct Cleaning in Spokane serves offices, retail spaces, medical clinics, and multi-unit buildings with larger duct networks and stricter occupancy demands. Commercial systems in Spokane face the same wildfire and agricultural dust load as residential, but with longer run times and more complex zoning. A typical commercial cleaning in Spokane runs $800-$2,500 depending on square footage, system complexity, and access. We schedule these jobs to minimize disruption to your operation, including early-morning or weekend slots when needed.
Systematic Zone-by-Zone Cleaning
Commercial buildings have branch lines, fire dampers, and variable-air-volume boxes that residential crews rarely encounter. Our technicians map your system first, then clean each zone under contained negative pressure so one section doesn’t contaminate another.
Post-Cleaning Documentation for Facilities Managers
We provide written verification of what was cleaned, what condition we found, and what we recommend for maintenance intervals. This documentation supports your indoor air quality program and satisfies most insurance or regulatory review requirements.
Trusted Brands We Service in Spokane
We clean ductwork connected to every major HVAC brand, and we stock Honeywell, Aprilaire, and Guardsman filtration products for Spokane homeowners who want to maintain cleaner air between service visits. If your system needs a filter upgrade or an indoor air quality add-on, we can source and install it during the same appointment. No waiting on parts shipped from out of state. Our equipment lineup includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-pressure machines for debris extraction, and Abatement Technologies HEPA filtration to capture what gets loosened. These are professional-grade tools, not shop vacs with extra hoses.
Common Air Duct Cleaning Problems We See in Spokane Homes
- Wildfire PM2.5 saturation in duct linings. Spokane’s basin geography traps smoke from Idaho, Montana, and eastern Washington fires every summer. When AQI hits hazardous levels, residents seal windows and run AC continuously, driving fine particulate deep into duct walls where standard filters can’t reach it. This load accumulates year over year and re-enters the living space every time the blower cycles.
- Degraded flex duct and fiberglass duct board in Spokane Valley ranches. The 1955-1980 tract homes in this area used materials that break down over decades. Fibers shed into the airstream, visible as dust accumulation around vents and on furniture. Cleaning without proper negative pressure makes this worse, not better.
- Asbestos-wrapped duct remnants in South Hill and Browne’s Addition craftsperson homes. Gravity-furnace conversions from the 1940s-1960s often left asbestos insulation on original trunk lines. Our technicians are trained to identify this and stop work immediately for proper abatement referral. It’s a liability and code reality that comes up far more in Spokane’s older housing stock than in newer markets.
- Blower motor and air handler neglect after smoke events. Many cleaners stop at the vents and trunk lines, leaving the heart of the system contaminated. Fine particulate settles on blower wheels and evaporator coils, then re-circulates during the next high-AQI event. We clean the full path, including the air handler.
Pricing for Air Duct Cleaning in Spokane, WA
Most Spokane homes run between $350 and $650 for a complete residential duct cleaning. Smaller condos or apartments with simple systems sometimes fall in the $275-$400 range. Larger homes with multiple HVAC units, complex duct layouts, or significant accessibility challenges can reach $750-$900. Commercial systems start around $800 and scale with square footage and system complexity.
What moves the number: the number of supply and return vents, whether the system has been cleaned before (first cleans take longer), accessibility of the main trunk lines, and whether the blower motor and air handler need dedicated attention. We don’t price per vent. We give one flat price per system, agreed in writing before a single vent is touched. No surprises at the door. Call (469) 972-3151 for your exact quote; estimates are free.

FAQs About Air Duct Cleaning in Spokane
Spokane’s inland basin traps wildfire smoke from surrounding states and concentrates Palouse agricultural dust, creating a dual particulate load that accumulates in ducts faster than Seattle’s marine climate allows. Seattle’s wetter air settles dust before it reaches ductwork; Spokane’s dry, windy conditions drive it deep into the system. Most Spokane homeowners benefit from cleaning every 3-4 years rather than the 5-7 typical in coastal markets. Call (469) 972-3151 for an exact quote; estimates are free.
Source removal physically extracts the particulate causing the odor, while fogging only masks it with chemical fragrance that reactivates when humidity changes. In Spokane’s wildfire-heavy summers, we’ve seen fogging treatments fail within weeks because the underlying PM2.5 remains embedded in duct linings. Our negative-air extraction with brush agitation removes the material itself, and HEPA filtration prevents recontamination of your living space during the process. Call (469) 972-3151 for an exact quote; estimates are free.
Expect oversized, irregularly shaped sheet-metal trunk lines from old gravity-furnace conversions, often with limited access points and possible asbestos-wrapped insulation remnants from the 1940s-1960s. Our technicians inspect first with a camera, and if we encounter asbestos, we stop work immediately and refer you to a licensed abatement contractor before any cleaning proceeds. This is a code and liability reality specific to Spokane’s older housing stock. Once cleared, we use specialized agitation tools designed for non-standard duct geometry. Call (469) 972-3151 for an exact quote; estimates are free.
Look for excessive dust accumulation on vent covers and nearby furniture, visible fibers in the airstream when sunlight hits a supply vent, or a musty or “dirty sock” odor when the system runs. The 1955-1980 ranch tracts in Spokane Valley used fiberglass duct board and flex duct that degrades significantly after four decades. Cleaning these systems without adequate negative pressure can break loose more fibers and worsen indoor air quality. Our Nikro units maintain controlled suction throughout the job to prevent this. Call (469) 972-3151 for an exact quote; estimates are free.
Not necessarily every season, but heavy smoke years with multiple hazardous-AQI weeks warrant inspection. We recommend a camera look after any summer where your home sealed up and ran forced air continuously for more than ten days of hazardous readings. The particulate load in those years can exceed what a standard filter captures by an order of magnitude. For moderate smoke years, stick to your 3-4 year interval unless you’re noticing odors, increased dust, or respiratory irritation when the system runs.
