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-$720 for a full residential system, with most jobs completed in a single visit and every price delivered in writing before we touch a panel. We’re CleanRun Duct Repair & Cleaning, and our Denver office coordinates crews across the metro every day. Call (719) 259-4520 for a written estimate with no obligation.
Denver’s housing stock tells its own story. In Harvey Park, Barnum, and Westwood, we’re still finding original sheet-metal ductwork from the 1950s and 60s that has never been professionally cleaned. In Capitol Hill and Baker, retrofitted runs snake through wall cavities never meant for forced air. Our Air Duct Cleaning team treats every job as a diagnosis first - because what we find inside determines what actually needs to happen.
Why CleanRun Air Duct Cleaning Parker Is Denver’s Preferred Air Duct Cleaning Company
We’ve served over 52,000 homes since 2013, every one with a written price before work started and a documented photo record when the crew left. That practice hasn’t changed. Denver homeowners can verify our license number on this page, and every technician arrives background-checked, uniformed, and identified by name - Haven Standard Clause 3: Verified Crews.
Our Denver office handles scheduling and dispatch locally. Crews know the difference between a 1950s ranch crawl space in Montbello and a pre-WWII retrofit in Baker, and they carry the right equipment for both. The 365-Day Done Right Promise applies to every job we do in Denver - backed in writing, not buried in a policy manual.
We publish our pricing ranges openly because Haven Standard Clause 1 requires it. No “call for a quote.” No coupon that balloons once the truck arrives. Bring us a competitor’s written estimate and we’ll deliver a Free Second Opinion, our number next to theirs, no charge.
Our Air Duct Cleaning Services in Denver
Residential Duct Cleaning
Denver’s dry climate and 5,280-foot elevation keep dust, pollen, and wildfire particulates suspended longer than in humid markets, which means residential systems here accumulate debris faster and differently. A typical full residential cleaning in Denver runs $380-$620 depending on system size and accessibility. We use negative-pressure extraction - a vacuum system that pulls debris out while agitation tools loosen it - with HEPA filtration on every job. The photo record shows you what came out of every run.
Commercial Duct Cleaning
Commercial systems in Denver’s mixed-use buildings along Colfax, in the RiNo district, and through the Cherry Creek corridor face unique loads: restaurant grease particulates, construction dust from constant renovation, and the same wildfire smoke infiltration that hits residential neighborhoods. Commercial pricing starts around $890 for small systems and scales with square footage and duct complexity. We schedule around business hours and deliver the same written price, same photo documentation, same 365-Day Done Right Promise.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Denver’s older homes they’re often the most visibly problematic - dust on registers, weak airflow to second-story rooms, temperature swings between the living room and bedrooms. But supply-only cleaning misses half the system. We price supply duct cleaning in Denver at $220-$380 as a standalone service, though we typically recommend it only as part of a full system evaluation. If your return trunk is disconnected in a crawl space, cleaning supplies alone won’t fix the dust problem.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Denver’s 1950s-70s ranches they frequently run through unconditioned crawl spaces where we’ve found them crushed, disconnected, or breached by rodents. Return cleaning runs $240-$420 in Denver, but the real issue is often structural - a disconnected trunk pulling crawl-space air straight into your system. Our crews photograph the full return path before recommending any work. If we find a breach, we quote the repair in writing before proceeding.
Full System Cleaning
This is what most Denver homes actually need. Full system cleaning covers supply ducts, return ducts, the plenum (the main distribution box above your furnace), and the air handler cabinet - the entire air path from intake to register. In Denver, a full system cleaning typically costs $480-$720 for homes under 3,500 square feet. We include video inspection of inaccessible runs, negative-pressure extraction with Rotobrush and Nikro equipment, and the complete before-and-after photo record. If we find disconnected or damaged ductwork, we quote sealing or repair separately, in writing, before any additional work.
Video Inspection
Denver’s retrofitted pre-WWII ductwork and buried crawl-space runs make camera inspection essential, not optional. Our video inspection service - $140-$220 as a standalone, or included in full system cleaning - lets us see inside wall cavities and underground trunks that agitation tools can’t reach blindly. We’ve found collapsed elbows, rodent nests, and standing water in Denver crawl spaces that no standard cleaning would have touched. The footage becomes part of your documented job record.

BeforeAfterTrusted Brands We Service in Denver
Our equipment roster includes Rotobrush agitation systems, Nikro negative-pressure extractors, and Honeywell media filters - brands customers can look up independently before agreeing to any price. We don’t make performance claims beyond manufacturer specifications. What we do guarantee is that the equipment matches the job: Rotobrush for light to moderate debris in accessible runs, Nikro HEPA systems for post-wildfire smoke remediation and fine particulate loads, and Honeywell filtration upgrades when Denver’s winter inversion events or summer fire seasons demand it. Parts and compatible media are stocked locally, so filter upgrades and component replacements don’t add delay.
Common Air Duct Cleaning Problems We See in Denver Homes
- Crushed or disconnected return trunks in crawl spaces. In Harvey Park, Barnum, and Westwood ranches built 1955-1975, original sheet-metal returns frequently sag, crush under floor joists, or pull completely free of the plenum. Our crew found exactly this in a 1948 ranch off Sheridan Boulevard - the return trunk crushed and pulling crawl-space dust straight into the air handler. Reconnecting and sealing the run fixed the homeowner’s persistent dust-on-register problem.
- Irregular retrofitted geometry in pre-WWII neighborhoods. Capitol Hill and Baker homes often have ductwork forced into wall and ceiling cavities never designed for forced air. Buried junctions and sharp turns trap decades of debris where standard agitation tools can’t reach without camera guidance first.
- Wildfire smoke particulate infiltration. Denver’s position at the base of the Front Range funnels June-September wildfire smoke directly into metro ductwork. At 5,280 feet, low humidity keeps fine ash and combustion particulates suspended longer, driving them deeper into systems than at lower elevations. Post-smoke-event cleaning requires HEPA-rated extraction, not standard vacuum equipment.
- Cleaning without sealing - the recurring failure. Crews remove debris from a system that’s still leaking crawl-space air and ground moisture back in through gaps at the plenum, register boots, and trunk connections. The debris returns within a season. We seal what we find, quoted separately in writing, because Haven Standard Clause 1 applies to the full scope of work needed.

FAQs - Air Duct Cleaning in Denver
A full system cleaning covers the complete air path - supply ducts, return ducts, plenum, and air handler cabinet - while supply-only cleaning addresses only the ducts pushing air into your rooms. In Denver’s older housing stock, we’ve found that supply-only jobs often miss the actual problem: disconnected return trunks in crawl spaces, crushed elbows in retrofitted wall cavities, and debris accumulation at buried junctions that only affect airflow when the full system is evaluated. Full system cleaning includes video inspection of inaccessible runs and the complete before-and-after photo record. Supply-only cleaning runs $220-$380; full system cleaning runs $480-$720. Call (719) 259-4520 for a written estimate on your specific system.
Denver’s dry, high-altitude environment and wildfire smoke exposure mean ducts here accumulate fine particulates faster than in humid climates, and those particulates stay airborne longer before settling into the system. We recommend video inspection every 3-5 years for Denver homes, with cleaning frequency driven by what the inspection finds - not by calendar alone. Homes in western suburbs closer to the Front Range wildfire corridor or with known crawl-space ductwork may need more frequent evaluation. Call (719) 259-4520 to schedule a camera inspection and written assessment.
The $79-$149 coupon offers in Denver typically cover a brief vacuuming of accessible registers with shop-vac equipment, no camera inspection, no photo documentation, and no evaluation of the return side or plenum. We’ve been called in after these jobs to find the same debris, the same disconnects, the same problems - because the “cleaning” never reached them. Our pricing reflects full negative-pressure extraction with professional Rotobrush and Nikro equipment, video inspection of buried runs, and the documented photo record that proves what was actually done. Haven Standard Clause 1 requires every price in writing before work starts, so you know exactly what you’re paying for before we begin.
Every CleanRun job in Denver concludes with a Documented Photo Record - before-and-after images from inside every duct run we accessed, delivered to you as part of the standard job record. Not a generic “after” shot of a clean register. Actual interior duct photography showing the condition we found and the condition we left. This practice has been standard on every one of our 52,000+ jobs since 2013. If a company can’t show you the inside of your own ducts, they can’t prove they cleaned them.
Yes - the 365-Day Done Right Promise applies to every job we perform in Denver and across our full service area.

This is Haven Standard Clause 5, and it’s why we publish our pricing, document our work photographically, and put every scope in writing before starting.
