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 Denver
Air duct cleaning in Denver typically runs $380-$780 for a full residential system, with most jobs completed in a single visit and a written price delivered before any panel comes off. We’re CleanRun Duct Repair & Cleaning, and our Denver office coordinates scheduling and dispatch for homeowners from Stapleton to Bear Valley, Golden Triangle to Montbello. If you’re on an unpaved road outside the metro core, or in a 1960s ranch near Sloan’s Lake with return-air chases that haven’t been opened in decades, the crew that arrives will have worked that exact setup before. Call (720) 513-5159 for a free written estimate.
Why CleanRun Air Duct Cleaning Aurora Is Denver’s Preferred Air Duct Cleaning Company
We’ve served over 52,000 homes since 2013, and a significant share of those jobs have been in Denver’s established neighborhoods where the housing stock tells its own story. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and every crew member is identified by name before arrival. Reviews from Denver customers consistently cite the photo record as the deciding factor - seeing the inside of their own ducts before and after, not a generic marketing image.
Dispatch from our Denver office means we’re routing crews through I-25, I-70, and Colfax corridor traffic patterns daily, not guessing at drive times from a distant call center. That local routing matters when you’re scheduling around work or managing a household with respiratory sensitivities. We know which Denver ZIPs see the heaviest post-wildfire particulate loading, and we adjust our HEPA filtration protocol accordingly.
Our license number is published on every estimate, not buried in a footer. Haven Standard Clause 1 requires a written price before any work starts - no exceptions, no “call for a quote” runaround. Bring a competitor’s written estimate and we’ll deliver a free second opinion, our number next to theirs, both in writing.
Our Air Duct Cleaning Services in Denver
Residential Duct Cleaning
Denver’s semi-arid climate keeps duct dust dry and mobile, so particulates stay suspended and recirculate through return-air systems rather than clumping and settling as they would in more humid metros. For homeowners in neighborhoods like Park Hill or Berkeley, where 1940s-1970s construction dominates, this means dust redistribution happens every time a Chinook drops temperatures forty degrees and your system cycles aggressively to catch up. Our residential service includes full negative-pressure extraction - we seal the system and draw debris out through a filtered vacuum collection point rather than blowing it into your living space - with a documented photo record of every duct run, before and after, delivered as part of your standard job record.
Commercial Duct Cleaning
Denver’s commercial buildings along Speer Boulevard, in the RiNo district, or near the Tech Center face a different contamination profile than residences: higher occupant density, more frequent filter changes that get skipped, and rooftop HVAC units that pull in particulates from I-25 and I-70 corridor traffic. We clean commercial supply and return systems with the same written-price protocol, scaling equipment to the building’s air-handler capacity. Before-and-after documentation is included on every visit, and we schedule around your operating hours to minimize disruption.
Supply Duct Cleaning
Supply ducts push conditioned air to your registers, and in Denver’s ranch homes - Lakewood, Wheat Ridge, older Aurora sections - these typically run through unconditioned crawl spaces or low attic chases where seams have opened over decades. We use Rotobrush agitation tools and negative-pressure extraction to loosen and remove debris without dislodging it into your home. The camera shows you the 3-inch debris build-up at the first elbow, or the open seam pulling crawl-space dust, before we quote the work.
Return Duct Cleaning
This is where Denver’s housing stock gets interesting. Return-air chases in 1960s ranches were often built from framed stud bays rather than sealed sheet metal - the “duct” is literally the gap between drywall and subfloor, open to the crawl space. In Wheat Ridge, a 1962 ranch’s return-air chase was built from open stud bays, so the ‘duct’ was literally the gap between drywall and subfloor; when our tech pulled the register, rodent nesting material and blown-in insulation were visible inside what the homeowner thought was a sealed system. We set up negative pressure, used agitation tools to loosen the debris, and ran HEPA filtration on the air handler while camera inspection confirmed the open seams feeding the return. The homeowner scheduled a follow-up before the next fire season. Return duct cleaning in Denver requires this level of inspection-first rigor - guessing at the duct configuration from the register alone misses the actual contamination pathway.
Full System Cleaning
After Front Range wildfire events - the 2020 Cameron Peak and East Troublesome fires, the December 2021 Marshall Fire in Boulder County - metro homeowners run HVAC systems continuously for indoor air filtration. That drives smoke particulates deep into ductwork where fine carbon debris embeds in existing dust layers and off-gasses for months. Cleaning supply ducts only after a wildfire smoke event but leaving the air handler and blower motor coated in fine carbon debris means the off-gassing continues. Our full system cleaning addresses the complete air path: return chases, air handler, blower motor, evaporator coil if accessible, supply trunks, and branch runs. We use professional-grade equipment from Abatement Technologies and Guardsman, brands you can verify independently.
Video Inspection
Every Denver job starts with camera inspection - not as an upsell, but as standard diagnostic practice. The video record shows you what we see: disconnected joints, rodent activity, fire-season carbon layering, or the open stud-bay construction that explains why your filters clog every six weeks. This footage becomes part of your documented photo record, timestamped and delivered with your invoice.

BeforeAfterTrusted Brands We Service in Denver
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - professional-grade tools customers can look up independently. We don’t claim performance beyond manufacturer specifications, and we name the brands so you can verify what will be in your home before agreeing to a price. For Denver’s older ranch housing stock, the combination of Rotobrush agitation and Nikro negative-pressure collection handles the debris volume we typically find in unsealed return chases and crawl-space supply trunks. Parts and consumables are stocked locally, so if your system needs a register replacement or a seal repair discovered during cleaning, turnaround is same-visit, not a return trip.
Common Air Duct Cleaning Problems We See in Denver Homes
- Neglecting return-air chases in older Denver ranches. Framed stud bays act as unsealed ducts that pull crawl-space dust, rodent detritus, and insulation into the living space. Homeowners change filters religiously but never realize the return path is open to the crawl space.
- Post-wildfire partial cleaning. Cleaning supply ducts only after a smoke event but leaving the air handler and blower motor coated in fine carbon debris that off-gasses for months. The system smells like smoke every time it cycles.
- Assuming low humidity means ducts stay clean. Denver’s dry air keeps particulates mobile, so they redistribute every time the system cycles through a Chinook-driven temperature swing. Dust doesn’t clump and settle here - it stays airborne and breathable.
- Unpaved road dust loading in rural fringe properties. Homes on gravel or dirt roads in unincorporated areas around Denver see pollen and mineral dust volumes that urban properties don’t. The cleaning interval for these properties is shorter, and the debris is more abrasive to blower motors and coils.
Pricing for Air Duct Cleaning in Denver, CO
A typical residential duct cleaning in Denver runs $380-$580 for a standard ranch or two-story home with 12-20 registers and a single air handler. Full system cleaning, including air handler and blower motor, ranges $520-$780. Commercial properties are priced by air-handler tonnage and duct complexity, with written estimates delivered on-site after video inspection.
What moves the price: register count, number of air handlers, accessibility of the air handler (attic vs. basement vs. crawl space), and whether we find open seams or disconnected joints that need sealing before cleaning is effective. Wood-burning stoves in foothills homes add a soot-debris component that requires additional HEPA filtration time.
Every estimate is a written price agreed before work starts - Haven Standard Clause 1. No per-vent pricing, no coupon that triples once the truck arrives. Call (720) 513-5159 for an exact quote; estimates are free.

FAQs - Air Duct Cleaning in Denver
Every 2-3 years, not the 5-7 year interval typical for paved-street urban properties. Unpaved roads generate mineral dust and pollen loading that filters capture incompletely; the excess migrates into return-air systems and accelerates blower-motor wear. Homes with gravel driveways or adjacent open land in areas like unincorporated Adams County or eastern Arapahoe County should schedule video inspection at the 2-year mark to assess debris volume. Call (720) 513-5159 to book a free inspection.
Yes. Wood heat generates fine particulate matter that bypasses stove-door seals and infiltrates return-air systems, especially in homes where the stove is the primary heat source and the HVAC fan runs continuously for distribution. The soot layer is more adhesive than standard household dust and requires longer agitation and HEPA filtration cycles. We’ve cleaned systems in Genesee and Evergreen where the blower motor housing held a quarter-inch of wood-soot deposit. Full system cleaning, not supply-only, is the appropriate scope. Call (720) 513-5159 for a written estimate.
Negative pressure contains the debris. In homes with open stud-bay returns or disconnected crawl-space joints - common in 1950s-1970s Denver construction - agitation without containment blows debris directly into living spaces or the crawl space. We seal the system and draw air through a filtered collection point, so what we loosen, we capture. The alternative is a shop-vac and a prayer, which is why we don’t do it. Call (720) 513-5159 to discuss your home’s duct configuration.
No. Low humidity suppresses mold, which is the primary driver in humid metros, but Denver’s 14-inch annual precipitation keeps particulates dry and mobile. They don’t clump and settle; they recirculate. Add Front Range wildfire smoke seasons, and you have a contamination cycle unique to this geography - fine carbon debris embedding in dust layers and off-gassing through the heating season. Duct cleaning here is a fire-season and rural-dust service, not an optional luxury. Call (720) 513-5159 for a seasonal assessment.
A technician feeds a lighted camera through your register openings and air-handler access points, recording the interior condition of every accessible duct run. You’ll see debris volume, joint integrity, and any rodent activity or insulation infiltration in real time. The footage is timestamped and included in your documented photo record, delivered with your written estimate or job invoice. There’s no charge for the inspection during a standard estimate visit. Call (720) 513-5159 to schedule.
