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 typically runs $400-$800 for a full system, with most jobs scheduled within a week and completed in a single day. At this elevation, blower motors work harder and longer than at sea level, pulling more debris through ductwork with every cycle. CleanRun crews coordinate dispatch from our Denver office and serve homeowners across the metro with written prices delivered before any panel comes off, every job backed by our 365-Day Done Right Promise. Call (720) 799-2292 for a free estimate.
Why Denver Homes Are Different
Denver’s mile-high elevation means HVAC blower motors run significantly longer cycles to move the same volume of conditioned air, accelerating dust accumulation inside ductwork year-round. The Front Range’s intensifying wildfire seasons, including the December 2021 Marshall Fire that burned neighborhoods in Louisville and Superior just 20 miles from downtown, drive residents to seal windows and run systems continuously during smoke events, embedding fine ash deep into ducts.
West-side and south-central neighborhoods like Harvey Park, Barnum, and Westwood contain heavy concentrations of 1950s-1970s ranch homes whose original sheet-metal ductwork was sealed with asbestos-containing mastic or duct tape, requiring assessment before disturbance. Capitol Hill and Potter-Highlands retain early 1900s bungalows and Denver Squares with gravity-furnace “octopus” duct runs, large uninsulated trunks retrofitted for forced air that create dead-end sections packed with decades of compacted debris. Our semi-arid climate keeps prairie soil suspended rather than clumped, while low humidity cracks flexible duct liner, causing interior surfaces to shed material into airflow.
Our Main Denver Services
Denver homeowners call us most often for these three services, each with its own dedicated Denver page.
Air Duct Cleaning in Denver
We clean the full supply and return network, from plenum, the main distribution box, through every duct run, the individual pathways, to each register, the room vents. In Denver, we regularly photograph 2-3 inch debris build-up at elbows in older ranch homes and compacted material in octopus trunk dead-ends. Every job includes a Documented Photo Record of every run, before and after. Air Duct Cleaning in Denver
Dryer Vent Cleaning in Denver
Lint accumulation restricts airflow and creates fire risk, especially in Denver’s dry climate where static charge accelerates buildup. We use negative-pressure extraction, suction-based debris removal, combined with rotary brushing to clear the full vent path from appliance to exterior termination. A written price is set before work begins, and the 365-Day Done Right Promise applies. Dryer Vent Cleaning in Denver
Duct Repair & Sealing in Denver
We replace deteriorated flex duct, seal disconnected joints, and repair damaged plenum connections, with special attention to asbestos-mastic assessments required in mid-century Denver housing stock. Sealing is verified with pressure testing, and all materials meet current code. The full photo record documents every repair. Duct Repair & Sealing in Denver

BeforeAfterHVAC Cleaning in Denver
At 5,280 feet, Denver’s HVAC systems run extended cycles that coat evaporator coils and blower assemblies with fine Front Range particulates faster than sea-level equivalents. Wildfire smoke events embed ash particles that standard filtration misses, accumulating on wet coil surfaces and recirculating during every heating or cooling call. HVAC Cleaning addresses these Denver-specific conditions with equipment sized for high-altitude system configurations.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow from registers, or cooling that cannot maintain setpoint during Denver’s summer afternoons.
What it costs in Denver
Evaporator coil cleaning typically runs $250-$450 depending on accessibility and contamination level.
How we do it
We apply foaming cleaner, then rinse with low-pressure water capture to protect the drain pan, finishing with a photo of the cleared coil surface.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust puffing from registers when the system cycles on.
What it costs in Denver
Blower assembly cleaning typically runs $200-$350 for standard residential units.
How we do it
We remove the blower wheel and housing, clean each blade with compressed air and solvent, reassemble, and photograph the assembly before closing the panel.
What HVAC Cleaning Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower assembly cleaning | $200-$350 |
| Full system HVAC cleaning | $400-$800 |
How do I know my HVAC needs cleaning versus just the ducts?
If rooms heat or cool unevenly, the system runs longer than it used to, or you see ice on the coil in summer, the HVAC components themselves are likely contaminated. Call (720) 799-2292 and we’ll assess whether duct cleaning alone will solve it or if the coil and blower need attention too.
Can wildfire smoke damage my HVAC system?
Ash particles are fine enough to pass standard filters and adhere to wet coil surfaces, where they become a persistent contamination source. After significant smoke events in the Denver area, we recommend HVAC inspection even if duct cleaning was recently completed.
Air Quality & Sanitizing in Denver
Denver’s low humidity and extended HVAC cycles create conditions where biological material desiccates rather than washes away, embedding fragments in duct liner cracks. Wildfire smoke introduces carbon-based particulates that standard cleaning cannot fully neutralize, requiring targeted treatment. Air Quality & Sanitizing addresses these persistent contaminants with application-specific methods.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible spotting on registers or duct liner, or aggravated respiratory symptoms during heating season.
What it costs in Denver
Whole-system mold treatment typically runs $500-$900 depending on extent and accessibility.
How we do it
We apply EPA-registered antimicrobial through the full duct network, with focused saturation at known moisture points, then verify with post-treatment photo documentation.
UV Light Installation
Signs you need it
Recurring biological growth after cleaning, chronic allergy symptoms, or systems in basements with limited natural light and ventilation.
What it costs in Denver
UV light installation typically runs $400-$700 including unit and placement.
How we do it
We mount the UV-C lamp at the coil or air handler location per manufacturer specification, wire to system power, and photograph placement for the job record.
What Air Quality & Sanitizing Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Mold treatment (whole system) | $500-$900 |
| UV light installation | $400-$700 |
| Combined sanitizing package | $600-$1,100 |
Does UV light actually work in Denver’s dry climate?
UV-C lamps target biological growth on wet coil surfaces, which occur during cooling cycles regardless of ambient humidity; Denver’s dry air does not prevent condensation on evaporator coils. The lamp runs continuously when the blower operates, suppressing growth between cleanings.
Is mold treatment safe for older ductwork?
We assess duct material and condition before applying any treatment; asbestos-containing mastic in mid-century Denver homes requires modified application methods that avoid disturbance. The written scope specifies exactly what will be treated and how.
Brands We Service in Denver
We stock parts and service equipment from Honeywell, Aprilaire, and Rotobrush, with other professional-grade tools from Nikro and Abatement Technologies on every truck. Most replacement components are available same-day from Denver-area supply houses. See our brands for full coverage.

FAQs About Air Duct Cleaning in Denver
Standard residential air duct cleaning does not require a permit in Denver; duct repair or modification that alters the building envelope may. We assess permit requirements during our initial inspection and include any necessary documentation in the written scope if repair work is involved.
Standard appointments are typically available within 5-7 business days; we do not maintain emergency or same-day slots because proper cleaning requires preparation and equipment setup that rushed scheduling cannot accommodate. Call (720) 799-2292 for current availability.
Most Denver HOAs regulate exterior appearance and contractor parking, not interior maintenance work itself; we carry proof of insurance and licensing for any HOA that requests documentation. We recommend notifying your association of scheduled work date to avoid parking or access issues.
