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.

AfterAir Duct Cleaning in Denver, CO
HVAC cleaning in Denver runs $280-$520 for a full system, with air quality and sanitizing services adding $180-$440 depending on method and home size. At 5,280 feet with wildfire smoke funneling off the Front Range, Denver’s thin, dry air keeps particulates suspended longer and drives them deeper into duct systems than at lower elevations. CleanRun crews coordinate dispatch from our Denver office and serve homeowners across the metro with written prices before any work starts and a Documented Photo Record of every duct run. Call (719) 259-4520 for a free estimate.
Why Denver Homes Are Different
Denver’s position at the base of the Front Range means wildfire smoke from Colorado’s increasingly severe fire seasons funnels directly into the metro, infiltrating home ductwork with fine ash and combustion particulates. At 5,280 feet, the low-humidity, thin atmosphere keeps those particulates suspended longer and drives them deeper into duct systems than at lower elevations - making post-smoke-event duct cleaning both more urgent and more necessary than in most US markets.
The housing stock compounds this. Inner-ring neighborhoods like Harvey Park, Barnum, Westwood, and Montbello are dense with 1950s-1970s ranch-style homes whose original sheet-metal ductwork has often never been professionally cleaned and runs through unconditioned crawl spaces vulnerable to rodent intrusion and ground moisture. Pre-WWII neighborhoods like Capitol Hill and Baker frequently have ductwork retrofitted into wall and ceiling cavities not purpose-built for forced air, creating irregular geometry that traps debris and complicates access.
Winter temperature inversions - Denver’s documented “brown cloud” episodes - trap vehicle exhaust and industrial pollutants for days, forcing HVAC systems to recirculate heavily contaminated air. Technicians working western suburbs like Wheat Ridge, Lakewood, and Arvada consistently find heavier fine particulate loads than expected, a signature of proximity to both the wildfire smoke corridor and the inversion zone.
Our Main Denver Services
Denver homeowners call us most often for these three services. Each has its own dedicated Denver page with full pricing and scope details.
Air Duct Cleaning in Denver
Full-system cleaning of supply and return ductwork, registers, and the main trunk line, with negative-pressure extraction to pull debris out rather than redistribute it. In Denver’s 1950s-1970s ranch stock, we regularly find original ductwork that has never been cleaned, running through crawl spaces where rodent activity and ground moisture add biological contamination to ordinary dust loads. Every job includes a written price before work starts and a Documented Photo Record of every duct run. Air Duct Cleaning in Denver has complete pricing and scope.
Dryer Vent Cleaning in Denver
Complete cleaning of the dryer exhaust run from appliance to exterior termination, with airflow testing before and after. Denver’s dry climate accelerates lint accumulation, and longer vent runs common in ranch-style homes with exterior laundry rooms create more friction points where buildup occurs. We document the full run with before-and-after photos and provide a written scope and price upfront. See Dryer Vent Cleaning in Denver for full details.
Duct Repair & Sealing in Denver
Repair of disconnected or damaged duct runs, sealing of leaks at joints and plenum connections, and replacement of degraded flex duct. Denver’s temperature swings and dry air degrade tape and mastic faster than in humid climates, and crawl-space ductwork in older neighborhoods suffers from rodent damage and corrosion. Every repair is photographed, priced in writing before work begins, and backed by our 365-Day Done Right Promise. Full details at Duct Repair & Sealing in Denver.

BeforeAfterHVAC Cleaning in Denver
Full HVAC cleaning in Denver addresses the reality of a system that has been pulling wildfire particulates, brown-cloud exhaust, and high-altitude dust through its components for years. In neighborhoods like Harvey Park and Westwood, we regularly open air handlers to find evaporator coils clogged with fine debris that standard filter changes never reached, and blower wheels caked with material that reduces airflow by 30 percent or more. HVAC Cleaning covers our full equipment and methodology.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow from registers, or cooling bills rising despite unchanged thermostat settings.
What it costs in Denver
Evaporator coil cleaning typically runs $180-$340 in Denver.
How we do it
We access the coil through the plenum - the main distribution box - apply foaming cleaner approved for indoor air handler use, rinse with low-pressure water capture, and photograph the coil before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, weak airflow despite clean filters, or dust puffing from registers at startup.
What it costs in Denver
Blower cleaning and balancing typically runs $160-$280 in Denver.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and contact-safe solvents, balance the assembly, and document with before-and-after photos.
What HVAC Cleaning Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$280 |
| Full system HVAC cleaning | $280-$520 |
How do I know my HVAC system needs cleaning, not just my ducts?
If your ducts are clean but rooms still heat unevenly, your coil or blower is likely clogged. We inspect both with a camera before quoting. Call (719) 259-4520 for a free estimate.
Does wildfire smoke damage HVAC components permanently?
Smoke particulates coat coils and blowers, reducing efficiency, but professional cleaning restores performance unless corrosion has set in. We photograph everything and tell you what cleaning will fix versus what needs replacement.
Air Quality & Sanitizing in Denver
Air quality and sanitizing in Denver addresses the specific contamination profile of a high-altitude metro at the wildland-urban interface: fine ash from Front Range fires, brown-cloud particulates trapped by winter inversions, and biological growth in crawl-space ductwork from older neighborhoods. After the December 2021 Marshall Fire blanketed the entire metro in ash for several days, demand for smoke-contamination duct cleanings spiked across Denver in a way that has no parallel in neighboring plains cities. Air Quality & Sanitizing details our full protocol.
Mold Treatment
Signs you need it
Musty odor from registers, visible growth around duct joints, or allergy symptoms that worsen when the system runs.
What it costs in Denver
Mold treatment typically runs $220-$400 in Denver.
How we do it
We apply EPA-registered antimicrobial through the duct system using a fogging device, with dwell time per manufacturer specification, then ventilate and document with before-and-after photos.
UV Light Installation
Signs you need it
Recurring biological growth after cleaning, or persistent odor that sanitizing alone does not resolve.
What it costs in Denver
UV light installation typically runs $340-$580 in Denver.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the air handler’s 24-volt circuit, and verify irradiance at coil surface with a meter.
What Air Quality & Sanitizing Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Mold treatment | $220-$400 |
| UV light installation | $340-$580 |
| Bacteria sanitizing | $180-$320 |
Is UV light worth it in Denver’s dry climate?
Yes - dry air does not prevent biological growth on coils and in drain pans, and UV-C addresses the mold and bacteria that survive despite low humidity. Call (719) 259-4520 for a free assessment.
Can sanitizing remove wildfire smoke odor from ducts?
Odor removal requires combination treatment: particulate extraction first, then oxidizing sanitizer for absorbed combustion compounds. We photograph and test before quoting scope.

FAQs About Air Duct Cleaning in Denver
No permit is required for cleaning. Duct repair or modification may need a Denver building permit if it alters the HVAC system’s capacity or routing; we handle permit research and include any required fees in the written quote.
Demand spikes after major smoke events like the 2021 Marshall Fire. We maintain a priority list for smoke-contamination cleanings and schedule as capacity allows, typically within 5-7 days during elevated demand.
Most Denver HOAs regulate exterior modifications like UV light penetrations or condenser placement, not interior ductwork. We review HOA guidelines when exterior access is required and include any needed documentation in the job record.
