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 runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. Our Air Duct Cleaning team dispatches from our Seattle coordination office and serves Spokane properties directly, from historic Browne’s Addition bungalows to rural spreads off the Palouse Highway. We know the valley’s conditions. Wood-heat soot, wildfire ash, and dust from unpaved county roads load Spokane ducts far heavier than standard estimates suggest. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Spokane’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Spokane customers return because we put the price in writing before touching the system. The 365-Day Done Right Promise covers every job: if the work fails within a year, we come back at no charge, including a free second visit. No negotiation, no runaround.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues. That’s The Garrison Standard, and it’s how we operate whether we’re driving to a South Hill ranch or a commercial kitchen in downtown Spokane.
Commercial Air Duct Cleaning in Spokane
Commercial Air Duct Cleaning in Spokane covers restaurants, medical offices, retail spaces, and multi-unit buildings where code compliance and occupant health are non-negotiable. Spokane’s winter inversions trap particulate for weeks, and commercial HVAC systems run longer hours than residential units, accelerating buildup in supply and return mains. A typical commercial duct cleaning in Spokane runs $800 – $2,400 depending on system size and access. We use Nikro negative-air machines to contain debris during cleaning, protecting occupied spaces.
Code Compliance and Documentation
Spokane County health inspectors and fire marshals increasingly ask for post-cleaning documentation. We provide written scope-of-work summaries and before-and-after photo documentation from our video inspection system. This protects your business record and satisfies insurer requirements.
Minimizing Downtime
We schedule commercial work during off-hours or zone the system so your operation isn’t interrupted. Our crew coordinates arrival with your facilities manager, works the agreed scope, and leaves the site clean. No surprises at the door.
Air Duct Cleaning Services in Spokane
Air Duct Cleaning Services in Spokane address the specific contamination patterns this valley creates. Winter temperature inversions trap wood-smoke particulate and dust for weeks, pulling it into HVAC systems that recirculate the same air 5 – 7 times daily. Hot, dry summers bring wildfire smoke from surrounding national forest. Rural properties on unpaved roads see additional loading from pollen and mineral dust. A typical residential system cleaning in Spokane runs $350 – $650; larger homes or systems with heavy contamination may reach $850.
Video Inspection Before and After
We run a camera through your ductwork before quoting and after completing work. You see what we see. This eliminates the bait-and-switch problem that’s plagued this trade: a low phone quote that balloons once the technician is inside your home.
Source Removal Methods
Our rotary brush systems from Rotobrush agitate debris from duct walls while negative-air collection captures it at the source. For the fragile galvanized and brick gravity systems common in Spokane’s pre-1950 housing stock, we adjust pressure and tool selection to prevent damage.

Trusted Brands We Service in Spokane
We clean and service systems connected to Honeywell, Aprilaire, and Abatement Technologies filtration and air handling equipment. Our Spokane crews carry common replacement parts for these brands, reducing return trips and wait times. If your system uses a Honeywell electronic air cleaner or an Aprilaire media filter, we inspect and reset the component during duct cleaning so it operates at rated efficiency. We don’t sell equipment you don’t need, and we explain what each component does for the air moving through your home.
Common Air Duct Cleaning Problems We See in Spokane Homes
- Wood-heat soot baked onto galvanized duct walls. Spokane’s long heating season and reliance on wood stoves creates a sticky creosote residue that standard rotary brushing alone won’t remove. We use agitation tools and solvent-free source removal to break it loose.
- Original octopus gravity furnace ducts in Browne’s Addition and similar historic neighborhoods. These massive, unsealed brick and galvanized systems from the 1900s haven’t been cleaned in decades. They require specialized negative-air equipment to handle volume without spreading contaminants through the house.
- Flex duct tearing and collapse in Moran Prairie and South Hill ranch homes. Mid-century flex duct degrades, creating debris traps and airflow restrictions. Our camera inspection identifies these failures before cleaning proceeds.
- Wildfire ash and pollen loading in rural properties on unpaved roads. Properties outside city limits near Airway Heights or Medical Lake pull in dust that settles in long, irregular duct runs. Without agitation tools and thorough camera verification, the far reaches stay dirty.
Pricing for Air Duct Cleaning in Spokane, WA
A typical residential air duct cleaning in Spokane runs $350 – $650 for a whole-home system with 10 – 15 supply and return vents. Larger homes, heavy contamination from wood heat or wildfire smoke, or systems requiring camera inspection and agitation tools for source removal may reach $750 – $850. Commercial systems start at $800 and scale with square footage and access complexity.
We do not quote per-vent prices. We quote one flat price per system, agreed in writing before work starts. The price does not move at the door. Every estimate is free, and every job includes before-and-after photos of your own ducts. Call (361) 326-5060 for an exact quote.

FAQs About Air Duct Cleaning in Spokane
Every 2 – 3 years, not the generic 3 – 5 year interval. Unpaved road dust, pollen from open land, and wood-heat soot load rural Spokane ducts faster than suburban systems. Properties with active agricultural operations or frequent wildfire smoke exposure may need annual inspection to determine timing. Call (361) 326-5060 to schedule a free camera inspection and we’ll tell you exactly what your system shows.
Yes, and this is specialized work we train for. These 1900s systems have massive, unsealed brick and galvanized runs that standard positive-pressure or shop-vac setups will contaminate rather than clean. We rig Nikro negative-air equipment to contain debris at the source, then use controlled agitation for source removal. We were called out to a 1908 bungalow near Browne’s Addition with original octopus gravity furnace ducts that had never been cleaned – a system so large and fragile we had to rig specialized negative-air equipment just to handle the volume. After camera inspection revealed decades of wood-smoke soot caked along the unsealed brick and galvanized runs, we used agitation tools for source removal and brought the return ducts back to clean bare metal. The homeowner immediately noticed better airflow and less of that persistent smoky smell on winter mornings.
Because wood-smoke particulate has adsorbed into your duct walls and recirculates whenever the blower runs. Spokane’s winter temperature inversions trap wood-smoke and fine particulate in the Spokane River Valley for weeks, making duct cleaning a seasonal health necessity here in a way that doesn’t apply to similarly sized cities outside the valley. The residue doesn’t leave on its own. Source removal cleaning with agitation tools breaks the bond and extracts it. Call (361) 326-5060 if you’re smelling smoke in months when no one nearby is burning.
Scale, access, and documentation. Commercial systems in Spokane have larger mains, more complex zoning, and code requirements for post-cleaning verification. Residential work focuses on occupant health and airflow restoration in smaller-gauge ductwork. Commercial jobs start at $800; residential at $350. Both receive written pricing before work starts and the same 365-Day Done Right Promise.
Yes. We clean ductwork in shops, barns, and detached outbuildings served by dedicated HVAC or heat pump systems. These long, irregular duct runs accumulate dust from unpaved roads and pollen from surrounding fields. We use camera inspection to verify the full length is reached, not just the accessible portions. Pricing depends on system size and access; call (361) 326-5060 for a written estimate.
