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.
Fast, Reliable Air Duct Cleaning Across Spokane Valley
Air duct cleaning in Spokane Valley typically runs $350 – $650 for a whole-home system, and most jobs are scheduled within a few days of your call. We’re the Air Duct Cleaning in Spokane Valley crew that shows up in uniform, prices the job in writing before touching anything, and stands behind it for a full year.
Dispatch and scheduling for Spokane Valley are coordinated from our Seattle office, but the technicians who arrive at your door live and work in the Inland Northwest. They know the difference between a 1978 rambler off East Sprague and a 1995 split-level near Mirabeau Park, and they know what fails in each. That matters because Spokane Valley’s building stock is remarkably consistent, entire neighborhoods were built from the same plans with the same materials, and the duct problems repeat block by block.

Why Hollis Air Duct Cleaning Is Spokane Valley’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning team operates under The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. In Spokane Valley, that standard means something specific. We know the semi-arid climate here drives heavy particulate accumulation, that spring dust storms from the Palouse deposit fine silt deep in return ducts, and that winter heating cycles redistribute that debris through homes built during the Valley’s 1970 – 2000 suburban expansion.
Our technicians are background-checked and uniformed. You know who is walking into your home before they arrive. Every job carries our 365-Day Done Right Promise in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.

Ductwork Cleaning in Spokane Valley
Ductwork Cleaning in Spokane Valley means more than vacuuming registers. It means addressing the original flexible ductwork installed in thousands of tract homes during the Valley’s build-out decades, duct that has now reached end of life in unconditioned crawlspaces and attics. Most Spokane Valley homes were built between 1970 and 2000 with rectangular floor plans and long trunk-and-branch runs. The original flex duct tears, disconnects at joints, and collects debris where homeowners cannot see it. Cleaning the visible supply vents while ignoring the crushed or disconnected runs below the floor is like washing a car with a broken hose: the work looks done, but the problem persists.
A typical residential ductwork cleaning in Spokane Valley runs $350 – $550 for a standard system, with larger homes or systems requiring more extensive agitation and negative-air extraction running toward $650. Commercial ductwork cleaning starts around $800 and scales with system complexity.
Supply and Return Cleaning
We clean both sides of the system. Supply ducts push conditioned air to your rooms; return ducts pull air back through filters that often miss fine Palouse silt. That silt settles in return trunks where standard household cleaning cannot reach it. We use rotary brush systems from Rotobrush and negative-air machines from Nikro to agitate and extract debris from the full run, not just the first few feet.
Crawlspace and Attic Run Access
Most Spokane Valley ductwork lives in unconditioned spaces. Our technicians access these runs, document what they find with video inspection, and show you before we quote any repair. No surprises. No work starts without your written approval of the price.
Air Duct Inspection in Spokane Valley
Air Duct Inspection in Spokane Valley is where we find the real problem. We were in a 1980s split-level off South Pines Road where the family had cleaned the vents for years but still saw dust film return within a week. Camera inspection from the air handler showed crushed original flex duct in the unconditioned crawlspace and a disconnected joint at the far trunk-and-branch run. We pulled the run under negative pressure, reconnected and sealed the joint, and the supply and return ducts finally held a steady flow instead of dumping silt from the Palouse into the registers.
An air duct inspection in Spokane Valley typically costs $150 – $250 as a standalone service, though we often waive or credit this fee toward cleaning when work proceeds. The inspection takes 45 – 90 minutes and covers the full system from air handler to register.
Video Documentation
We run cameras through your ductwork and show you what we see. Crushed flex, disconnected joints, rodent intrusion, or heavy silt buildup. You see it before we quote it. The price is written down before any work starts.
System Mapping
Many Spokane Valley homes share identical floor plans with neighbors. Our technicians map your specific trunk-and-branch layout, identify where original materials are failing, and note whether sealing with mastic or full run replacement is the appropriate fix. This prevents paying to clean a system that will just recontaminate.
Trusted Brands We Service in Spokane Valley
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use, not hardware-store gear, and we stock components for fast turnaround on Spokane Valley jobs. When inspection reveals a failed flex run or compromised joint, we can often seal or replace it during the same visit rather than scheduling a return trip. That efficiency matters in a market where entire subdivisions hit duct failure simultaneously, the same original flex runs in your neighbor’s crawlspace are failing in yours.
Common Air Duct Cleaning Problems We See in Spokane Valley Homes
- Crushed or torn original flex duct in crawlspaces. The flexible duct installed in 1970s – 1990s Spokane Valley tracts was not built to last 40+ years in unconditioned spaces. We find it collapsed under its own weight, torn by rodent activity, or disconnected at joints. Cleaning alone cannot fix this; reconnection and sealing are required.
- Fine Palouse silt deep in return ducts. Spring dust storms from surrounding agricultural areas deposit material that passes through standard filters and settles in return trunks. Standard household dust removal misses it. It re-enters the air on every heating cycle until extracted with negative-air equipment.
- Disconnected joints at trunk-and-branch transitions. The long runs typical of Spokane Valley’s rectangular floor plans create stress points where flex meets rigid duct. These separations dump conditioned air into crawlspaces and pull unfiltered air back into the system.
- Assuming replacement is the only option. Some competitors quote full system replacement when the real issue is a disconnected or crushed flex run that needs reconnection, sealing with mastic, and proper support. Inspection first. Replacement only when necessary.
Pricing for Air Duct Cleaning in Spokane Valley, WA
Whole-home residential air duct cleaning in Spokane Valley runs $350 – $650 depending on system size, accessibility, and whether sealing or repair work is needed alongside cleaning. A standard 1,500 – 2,500 square foot home with accessible crawlspace typically falls in the $350 – $450 range. Larger homes, commercial systems, or jobs requiring extensive negative-air extraction and rotary brush agitation run higher. We do not price per vent. One flat price per system, agreed in writing before work starts.
Air duct inspection is $150 – $250 standalone, credited toward cleaning when you proceed. Duct Sealing - Spokane Valley as an add-on typically runs $200 – $400 depending on the linear footage of compromised joints and runs. What affects cost: system size, crawlspace or attic accessibility, extent of debris buildup, and whether repair work is needed beyond cleaning. We do not bait with a low teaser and inflate at the door. The price you approve is the price you pay.

FAQs About Air Duct Cleaning in Spokane Valley
Because most Spokane Valley homes were built between 1970 and 2000 as clustered tracts with identical floor plans, entire subdivisions hit duct failure at the same time. The same original flex runs in your neighbor’s crawlspace are failing in yours. Cleaning removes accumulated debris, but if the duct itself is torn, disconnected, or poorly sealed, that debris returns immediately. We inspect first, then sequence cleaning and sealing so you don’t pay to clean a system that will just recontaminate. Call (361) 326-5060 to schedule an inspection.
Yes. We use video inspection cameras fed through existing register openings and the air handler access panel. In Spokane Valley’s typical trunk-and-branch systems, we can see the full run from air handler to vent, including crushed flex and disconnected joints in crawlspaces or attics. No drywall removal. No structural intrusion. The camera footage is shown to you before any work is quoted. Call (361) 326-5060 for a free estimate.
Because the source was never addressed. Standard cleaning of visible supply vents ignores crushed or disconnected flex duct in unconditioned crawlspaces, where the system pulls unfiltered air and redistributes it. Fine Palouse silt from spring dust storms also settles deep in return ducts beyond where household methods reach. We find the source with camera inspection, then clean and seal the full system so the dust stays out. Call (361) 326-5060 if you’re seeing dust return within days of cleaning.
Yes. The blower motor sits upstream of your ductwork. If it’s coated with debris, it contaminates clean ducts on the first cycle. During our inspection, we assess the air handler and blower assembly. If cleaning the blower is needed, we include it in your written quote before starting. We do not clean ducts and leave a dirty blower to re-soil them. Call (361) 326-5060 for an estimate that covers the full system.
Camera inspection tells us. We show you the footage. If your ducts are intact with normal accumulation, cleaning alone is appropriate. If we find crushed flex, disconnected joints, or failed seals, we quote the repair and sealing work separately, and you decide before any work proceeds. No pressure. No work starts without your written approval of the full price. Call (361) 326-5060 to schedule an inspection and get the full picture.
