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 air quality and sanitizing services adding $200-$500 depending on the scope. We dispatch crews from our Denver office to handle the specific conditions Front Range homeowners face: post-wildfire particulate loads, 1950s-1970s ranch ductwork with crawl-space return paths, and Chinook-driven temperature swings that keep debris circulating year-round. Every job starts with a written price before a panel comes off, and every duct run is photographed before and after. Call (720) 513-5159 for a free estimate.
Why Denver Homes Are Different
Denver sits in the direct smoke corridor of Colorado’s increasingly severe Front Range wildfire seasons. After the 2020 Cameron Peak and East Troublesome fires or 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-gases for months. This post-wildfire contamination cycle creates demand tied to Colorado’s fire calendar, not the conventional allergen schedule.
The housing stock compounds this. Across Lakewood, Wheat Ridge, older Aurora, and Englewood, 1950s-1970s ranches feature sheet-metal supply trunks through unconditioned crawl spaces and return-air systems retrofitted during AC additions decades later. Patchwork ductwork has open seams that pull crawl-space debris, rodent detritus, and blown-in insulation fragments directly into the air stream. In Wheat Ridge and older Englewood, framed stud-bay return chases - a 1960s Denver shortcut - mean the “duct” is literally the gap between drywall and subfloor, open to the crawl space. We find active rodent nesting material inside what homeowners believe is sealed.
Denver’s semi-arid climate keeps mold rare but fine particulates mobile. Low humidity prevents agglomeration, so dust stays airborne longer. Chinook temperature swings of 40-60°F in a single day force aggressive HVAC cycling, accelerating debris migration into return-air cavities.
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 local specifics.
Air Duct Cleaning in Denver
Full negative-pressure extraction of supply and return ductwork, register to plenum, with a documented photo record of every run. In Denver’s ranch stock, we pay particular attention to crawl-space trunk connections and stud-bay returns where debris concentrates. We use Rotobrush and Nikro equipment sized for residential systems. Air Duct Cleaning in Denver covers complete pricing and what we typically find in local homes.
Dryer Vent Cleaning in Denver
Lint evacuation from dryer terminal to appliance connection, with airflow verification and termination inspection. Denver’s dry climate produces brittle lint that fractures and compacts in vertical runs common in multi-story infill. We document blockage severity and material removed. Dryer Vent Cleaning in Denver has full details.
Duct Repair & Sealing in Denver
Sheet-metal repair, flex-duct replacement, and mastic sealing of supply and return systems. Denver’s temperature swings stress tape adhesives and expand contraction gaps at joints. We seal with materials rated for the cycling. Duct Repair & Sealing in Denver covers local repair scenarios.

BeforeAfterHVAC Cleaning in Denver
Full HVAC Cleaning in Denver addresses what the climate and housing stock create: wildfire particulate embedded in coils and blower assemblies, debris pulled through unsealed return paths, and accelerated component fouling from Chinook-driven cycling. In a 1960s Wheat Ridge ranch we serviced last spring, the camera showed a 3-inch debris build-up at the first elbow of a stud-bay return - cellulose insulation, rodent nesting material, and fine ash from the previous fire season packed together. The homeowner had run the fan continuously during smoke events, not realizing the return was open to the crawl space.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow at registers, or a musty odor when the AC first cycles on after winter.
What it costs in Denver
Evaporator coil cleaning typically runs $250-$450 in Denver, depending on accessibility and contamination level.
How we do it
We remove the access panel, apply foaming cleaner formulated for aluminum fins, 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, uneven airflow room to room, or dust puffing from registers at startup.
What it costs in Denver
Blower assembly cleaning in Denver generally falls between $200-$350 for standard residential units.
How we do it
We remove the blower wheel and housing, clean each vane with compressed air and solvent, inspect the motor bearings, and reassemble with torque verification.
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 (coil, blower, air handler) | $400-$800 |
How do I know my HVAC system needs cleaning, not just my ducts?
If you smell must when the AC starts, see ice on the coil, or feel weak airflow despite clean filters, the components need direct attention. Duct cleaning alone won’t reach the blower or coil. Call (720) 513-5159 and we’ll inspect both.
Does wildfire smoke residue stay in the HVAC components?
Yes. Fine carbon particulate from Front Range fires adheres to wet coil surfaces and blower vanes, then off-gases when heated. We find this in Denver systems every fire season. Component cleaning removes the source, not just the ducts.
Air Quality & Sanitizing in Denver
Air Quality & Sanitizing in Denver targets what Air Quality & Sanitizing elsewhere cannot: wildfire-specific particulate chemistry, rodent-borne pathogens from open stud-bay returns, and the bacterial load that accumulates when debris sits undisturbed in dry conditions. Denver’s low humidity suppresses mold but preserves other biological material in a desiccated, readily aerosolized state. When Chinook winds force sudden system cycling, that material distributes through the house.
Bacteria Sanitizing
Signs you need it
Persistent odor after duct cleaning, recent rodent activity in returns, or family members with unexplained respiratory irritation.
What it costs in Denver
Bacteria sanitizing for a full residential system in Denver typically runs $200-$400.
How we do it
We apply EPA-registered sanitizer through the duct system using a fogging manifold, with dwell time per manufacturer specification, then ventilate and verify with ATP testing.
UV Light Installation
Signs you need it
Repeated coil contamination between cleanings, allergy symptoms that persist despite filtration upgrades, or a home in a high-pollen Front Range corridor.
What it costs in Denver
UV-C lamp installation in Denver generally costs $300-$600 per air handler, including the lamp and power supply.
How we do it
We mount the lamp downstream of the coil with sight-glass access, wire to the blower relay for automatic operation, and show the customer the installation photo.
What Air Quality & Sanitizing Costs in Denver
| Item | Typical range in Denver |
|---|---|
| Bacteria sanitizing (whole system) | $200-$400 |
| UV-C lamp installation | $300-$600 |
| Combined sanitizing + UV installation | $450-$900 |
Does sanitizing remove wildfire smoke smell from ducts?
Sanitizing addresses biological odor sources; smoke odor requires oxidation treatment or physical removal of carbon deposits. We assess the source first, then specify the right method. Call (720) 513-5159 for an inspection.
How long does UV light treatment take to show results?
Coil surface contamination drops within one to two weeks of operation; airborne reduction depends on system runtime and takes four to six weeks to stabilize. We document baseline and follow-up with photo records.
Brands We Service in Denver
We stock parts and service equipment from Honeywell, Aprilaire, and Guardsman, with most common filters, UV lamps, and sanitizer concentrates available from our Denver office. Unusual Aprilaire media or Honeywell electronic air cleaner cells typically arrive next business day.

FAQs About Air Duct Cleaning in Denver
Standard residential duct cleaning and HVAC component cleaning do not require permits in Denver. Duct modifications, new returns, or furnace replacement do. We handle permit documentation when repair work crosses into modification scope, and we note permit status on the written scope before starting.
Demand spikes after major Front Range fires, but we do not artificially limit appointments. Call (720) 513-5159 for current availability; we maintain equipment inventory in Denver to avoid supply delays during high-demand periods.
Most Denver-area HOAs regulate exterior modifications like UV lamp power routing through common walls, not interior duct access. We review HOA documentation when exterior penetration is required and include compliance steps in the written scope.
