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 HVAC Cleaning Across Denver
HVAC cleaning in Denver costs between $390 and $780 for a full system on a typical single-family home, with coil cleaning and blower cleaning running $180 to $340 as standalone services. We work across Denver’s older ranch neighborhoods and newer infill developments weekly, from Harvey Park to Central Park. If your system is short-cycling, blowing weak air, or carrying a stale odor that gets worse with heat, the ductwork and components likely carry years of compacted dust and smoke particulate. Call (806) 606-6902 for a written price before any work begins.
Why CleanRun Air Duct Cleaning Is Denver’s Preferred HVAC Cleaning Company
CleanRun Air Duct Cleaning has served the Denver metro since our founding in 2013, completing documented HVAC cleaning work in 52,000+ homes across the Front Range. Our Denver customers keep coming back for one reason: we show them the inside of their ductwork before and after, with a photo record included on every visit. Tomas Reyes, who leads our team, built the company on written pricing and verifiable results, not phone estimates that change when the van arrives.
We answer every call with a live person, day or night, and our technicians arrive in uniform, background-checked, identified by name before they walk in the door. For Denver homeowners who bought between 2015 and 2025 at Front Range prices, that level of documentation matters. You’re not getting a shop-vac pass and an invoice. You’re getting a written scope, a camera inspection, and a photo record of every duct run we touch.
Our crews know Denver’s housing stock the way a general contractor does. We know what a 1962 ranch in Harvey Park looks like inside its ducts versus a 2018 build in Central Park. That local knowledge changes what we recommend and what we quote.
Our HVAC Cleaning Services in Denver
Evaporator Coil Cleaning
Denver’s dry, dusty air loads evaporator coils faster than humid climates do. A coil caked with compacted mineral dust can’t transfer heat properly, which means your AC runs longer and your electric bill climbs. We clean coils with professional-grade equipment from Rotobrush and Nikro, restoring airflow without damaging fins. In Denver, we recommend coil cleaning as part of any full HVAC cleaning, especially in homes near major arteries like Federal Boulevard or Colfax where road dust is constant.
Blower Cleaning
The blower motor and fan wheel in a Denver furnace accumulate fine particulate that compacts into a hard crust over heating season. A dirty blower wheel throws off balance, strains the motor, and can cut airflow by 20 percent or more. We remove the blower assembly, clean the wheel and housing, and document it all. For older Denver homes with original blowers from the 1970s, this service often pays for itself in the first season of reduced strain on the motor.
Condenser Cleaning
Outdoor condenser units in Denver sit in a high-desert environment with constant wind-driven dust plus cottonwood and sage debris. We clean condenser coils and fins, clear the surrounding area, and verify the unit is pulling air properly. Homes in western Denver neighborhoods like Barnum and Westwood, which sit closer to open space and prevailing westerly winds, tend to have the heaviest condenser loading.
Air Handler Cleaning
The air handler is the lung of your HVAC system, moving every cubic foot of conditioned air through your Denver home. We clean the blower, the housing, and the evaporator coil as a unit, then treat the interior surfaces to resist microbial growth. For Denver homeowners with allergies or homes downwind of recent wildfire burns, this cleaning makes the most noticeable difference in daily air quality.

Common HVAC Cleaning Problems We See in Denver Homes
- Compacted mineral dust in original galvanized ductwork. Denver’s average 14 inches of annual precipitation leaves dust airborne far longer than in humid cities. In 1950s-1970s ranch homes from Harvey Park to Montbello, that dust compacts into hard deposits inside original sheet-metal ducts that have never been professionally cleaned.
- Crushed or disconnected duct runs in older basements. Decades of settling in Denver’s expansive clay soils shift foundations and crush duct runs routed through unfinished basements. We find disconnected returns in roughly one in four older Denver ranches we inspect.
- Wildfire smoke oils absorbed into return plenums. After the December 2021 Marshall Fire, we began finding smoke oils soaked into flex-duct liners and plenum surfaces across the metro. Standard vacuuming does not remove these oils; they require encapsulant treatment or they re-emit during heating season.
- Rapid recontamination after cleaning without sealing. Denver’s frequent 40-to-70-degree daily temperature swings force HVAC systems to cycle constantly. If we clean ducts but skip sealing gaps and crushed runs, the system pulls dirty air right back in within months.

Why Denver’s Wildfire Smoke Changes Everything About Duct Cleaning
Denver sits at the base of the fire-prone Front Range, and the December 2021 Marshall Fire changed what we find inside ductwork across the entire metro. Smoke from that fire pushed fine particulate and volatile oils into homes from Boulder County to Aurora. What’s different about Denver versus a city that gets occasional wildfire haze: those smoke oils absorbed into return plenums and flex-duct liners, and they don’t come out with standard source-removal vacuuming.
We learned this the hard way, the way every honest contractor learns anything. On a 1962 ranch in Harvey Park, our technician’s camera inspection revealed a disconnected return run in the basement and decades of compacted mineral dust from Denver’s dry, windy air. We performed source removal under negative pressure with HEPA filtration, then sealed the crushed duct. The homeowner mentioned lingering smoke odor from the Marshall Fire, so we treated the return plenum with an encapsulant designed for smoke oils. Six months later, the odor held. Without that treatment, she’d have called us back by heating season.
Denver also sits in a high-desert basin prone to temperature inversions that trap the “brown cloud” of Front Range pollution. That means homes recirculate dirtier outdoor air through ducts year-round. Combine chronic inversion pollution with acute wildfire events, and you get duct contamination that is both a seasonal crisis and a slow-burning problem unique to this geography.
What We Find in Denver’s Older Ranch Homes
Denver’s post-WWII building boom produced thousands of ranch-style homes from the 1950s through the 1970s, concentrated in Harvey Park, Barnum, Westwood, and Montbello. Those homes almost universally feature original galvanized sheet-metal ductwork routed through unfinished basements, now 50 to 70 years old. Most have never been professionally cleaned.
What we find inside those systems is specific to Denver. The original duct runs often show crushed sections from decades of foundation settling in our expansive clay soils. Disconnected returns are common where the original sheet-metal joints worked loose. And the Colorado dust itself behaves differently than dust in, say, Houston or Atlanta. Denver’s dry air keeps mineral dust airborne longer, and it compacts into hard, caked deposits inside duct runs rather than flushing out with seasonal moisture. A shop-vac pass will loosen the surface layer and leave the compacted material behind.
That’s why we frame older Denver homes differently. Cleaning is step one. Sealing is step two. If we clean your Harvey Park ranch and leave a disconnected return open, Denver’s constant HVAC cycling pulls dirty basement air right back into the system within months. You’ll be calling us again next year wondering why the air still feels stale. We’d rather fix it right the first time and document what we did.

FAQs - HVAC Cleaning in Denver
Denver’s position at the base of the fire-prone Front Range means wildfire smoke from events like the December 2021 Marshall Fire penetrates duct systems across the metro and leaves smoke oils that standard vacuuming cannot remove. Those oils absorb into return plenums and flex-duct liners, then re-emit during heating season. In Denver, we routinely recommend encapsulant treatment for homes with smoke exposure history, not just source-removal cleaning. Call (806) 606-6902 if your home had smoke odor after the Marshall Fire and it’s coming back when the furnace runs.
Denver averages about 14 inches of precipitation per year, which leaves fine mineral dust and allergens airborne far longer than in humid markets. That dry, windswept air loads return ducts with particulate that clumps and compacts instead of getting flushed out by moisture. Rapid temperature swings of 40 to 70 degrees within a single day also force HVAC systems to cycle far more frequently, drawing in dirtier air and depositing more debris throughout the duct system.
Denver’s 1950s-1970s ranch homes in neighborhoods like Harvey Park, Barnum, and Westwood commonly feature original galvanized sheet-metal ducts routed through unfinished basements, now 50 to 70 years old. We regularly find crushed or disconnected runs from decades of foundation settling, and those failed connections draw dirty basement air into your living space. Cleaning alone won’t fix a disconnected return; sealing the ductwork is often the real repair.
Smoke odor returns because the oils from wildfire smoke absorbed into return plenums and flex-duct liners are not removed by vacuuming alone. These oils re-emit when the furnace heats up, which is why many Denver homeowners report the smell “coming back” with the first cold snap of fall. The fix is encapsulant treatment applied directly to the affected surfaces. If you had a cleaning after the Marshall Fire and the smell returned, we can inspect and treat the plenum. Call (806) 606-6902 for a camera inspection and a written scope.
Yes. CleanRun Air Duct Cleaning follows NADCA standards for source-removal HVAC cleaning, including negative-pressure extraction with HEPA filtration on every Denver job. We use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we document every duct run with before-and-after photos as part of the standard job record.
