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.

Why CleanRun Air Duct Cleaning Is Highlands Ranch’s Preferred HVAC Cleaning Company
Highlands Ranch homeowners tend to research before they call. They want to see a written price, documented results, and a company that can show what it did. That’s how we’ve operated since Tomas Reyes founded CleanRun in 2013, and it’s the reason our HVAC Cleaning work in Highlands Ranch comes with a Documented Photo Record on every visit. You see the inside of every duct run before and after, not just a final invoice that says “cleaned.”
Highlands Ranch customers call us because they’ve either been burned by a low-ball coupon price or watched a tech run a shop vac through one register and call it a day. We don’t do either. The 365-Day Done Right Promise is in writing on every job: if it’s not right, we make it right. No manager approval required. That promise matters in a community where homes are large, duct runs are long, and the difference between a real clean and a surface wipe is hard to see without a camera.
When something goes wrong with your HVAC in Highlands Ranch, it’s usually not an emergency in the middle of the night. What it is: an airflow problem, a dust problem, or a coil that’s been strangling your system for years. We respond to Highlands Ranch service calls on a scheduled basis with honest time windows, and we show up when we say we will.
Our HVAC Cleaning Services in Highlands Ranch
Evaporator Coil Cleaning
We see this constantly in Highlands Ranch. The evaporator coil sits in the air handler and does the actual cooling. After years of pulling Front Range air across it, the coil gets caked with a gray film of fine particulate that acts like insulation and kills efficiency. A typical evaporator coil cleaning in Highlands Ranch runs $180-$280 as part of a full system clean. Homes near Wildcat Mountain and along McArthur Ranch Road tend to run dirtier coils simply because of how much the AC cycles in summer.
Blower Cleaning
The blower wheel is what pushes air through your ducts. If the wheel blades are loaded with dust, the whole system works harder to move less air. In Highlands Ranch homes with finished basements, we often find the blower pulling air from spaces where drywall dust settled years ago and never left. Blower cleaning in Highlands Ranch typically runs $120-$200. It’s not glamorous work, but it’s where a lot of the noise and inefficiency lives.
Condenser Cleaning
Your outdoor condenser sits through everything Highlands Ranch weather throws at it: hail, cottonwood fluff in June, dust from open lots during construction season. A proper condenser cleaning means pulling the fan, clearing debris from the coil fins, and flushing the unit so it can reject heat again. In Highlands Ranch, condenser cleaning runs $130-$220 depending on unit size and access. Homes on larger lots near Roxborough Park Road often have more debris accumulation because of the open space and wind patterns.
Air Handler Cleaning
Air handler cleaning is where Highlands Ranch’s finished basement layout really matters. In most production-built two-story homes, the air handler sits in the basement or a utility closet, and the duct branches run up through walls and across ceiling joists. When we open the air handler cabinet, we see what’s been bypassing the filter for years: construction dust, pet hair, sometimes drywall chunks from the original build. Air handler cleaning in Highlands Ranch typically runs $160-$260 as part of a full HVAC cleaning package.

BeforeAfterTrusted Brands We Service in Highlands Ranch
Highlands Ranch homes run equipment from all the major manufacturers, but the older stock leans heavily toward Carrier, Trane, Lennox, and Rheem systems installed during the 1990s and 2000s build-outs. We service all of them. For the cleaning itself, we use Rotobrush and Nikro negative-pressure extraction equipment, and when coil treatment is part of the job, we use Guardsman products that can be independently verified. We don’t use homeowner-grade equipment. We use professional gear that does in four hours what a filter change can’t do in four years.
Common HVAC Cleaning Problems We See in Highlands Ranch Homes
- Disconnected flex duct in finished basements. Homeowners finish the basement, someone adds a duct branch to a bonus room, and the connection wasn’t sealed properly. Years later, that run is dumping conditioned air into the joist cavity. The homeowner just knows the basement room never gets warm or cold enough. We find these on camera, reconnect them, and seal the joints with mastic.
- Crushed flex runs behind drywall. The 2000-2006 build wave in Highlands Ranch moved fast. Lots of homes have flex duct that got kinked or crushed during construction when drywallers or electricians pushed it out of the way. That crushed run stays that way for 20 years, restricting airflow and trapping debris. A camera inspection is the only way to see it without opening the wall.
- Evaporator coils loaded with fine Front Range particulate. At 5,900 feet elevation with low humidity, fine dust stays airborne longer than at sea level. Every cooling season, that dust plasters itself onto the coil. By July, your system is working against itself. Coil treatment alone won’t fix it if the ductwork upstream is still feeding debris onto the coil.
- Construction dust from the 2000s still in the ducts. Homes built during the peak construction wave in southern and eastern Highlands Ranch were often occupied while adjacent lots were still being framed. Drywall dust, concrete particulate, and loose-fill insulation fibers were pulled into brand-new duct systems before the first owner even moved in. In many of those homes, it’s still there. We see it on camera. The homeowner sees it in the before photos.

FAQs - HVAC Cleaning in Highlands Ranch
Because Highlands Ranch was built fast, mostly between 1985 and 2010, with production tract housing where finishing a basement meant running new flex duct through tight joist spaces while drywall went up at the same time. The result is branch connections that were never sealed properly and flex runs that got kinked or crushed during construction. Older Denver neighborhoods have more rigid metal ductwork and fewer post-build basement retrofits, so the failure modes are different. In Highlands Ranch, a camera inspection during an HVAC cleaning will find disconnected or crushed runs in a meaningful percentage of homes. Call (806) 606-6902 if your basement rooms stay dusty or never hold temperature.
Yes, and that particulate is exactly what source removal with HEPA-filtered negative pressure is designed to address. The 2020 fire season drove weeks of fine combustion particulate through homes across the Front Range, and Highlands Ranch took a heavy dose. That material settles inside duct runs, on blower wheels, and across evaporator coils. A standard filter change does not remove it. Our process involves agitating the duct interior while pulling negative pressure with HEPA filtration, then photographing the result. You’ll see the before and after. Call (806) 606-6902 to schedule a cleaning with a written price first.
Sealing a disconnected flex duct run in Highlands Ranch typically runs $150-$350 depending on access and whether we need to open drywall. If it’s a simple reconnect at a basement branch, it’s on the lower end. If the run was crushed and needs replacement, the cost goes up based on run length and accessibility. The key point: we show you the camera footage first, hand you a written price, and do nothing until you approve. That’s the Haven Standard, and it applies on every job without exception.
Highlands Ranch sits at about 5,900 feet, and the temperature can swing 40 degrees between noon and midnight during swing seasons. That means your HVAC system runs more hours per year than a comparable home at sea level. More run-hours means more air pulled through the system, which means more particulate deposited on coils, blowers, and duct walls. Homes in Highlands Ranch generally need HVAC cleaning on the same or shorter interval than lower-altitude suburbs, even with good filter habits. If your system hasn’t been cleaned in five years or more, you’re overdue.
Because they were occupied while surrounding lots were still under active construction. The peak 2000-2006 build wave in southern and eastern Highlands Ranch meant homeowners were living in their new houses while drywall crews, concrete trucks, and insulation installers worked next door. That dust was pulled into brand-new HVAC systems during move-in, and in many homes it has sat undisturbed for nearly two decades. We see it on camera: a fine gray coating on the duct floor near the first elbow, loose-fill insulation fibers caught on the registers, drywall dust caked onto the blower wheel. It’s not a maintenance failure. It’s the result of when and where the house was built. Call (806) 606-6902 to see what’s in your ducts.
We recently cleaned the HVAC system in a Richmond American two-story off Ranch Road where the finished basement’s bonus room had a secondary flex duct run added after the original build. During camera inspection, our tech found a disconnected supply duct behind drywall that had been dumping conditioned air into the joist cavity for years, and a crushed return line reducing airflow to the basement. We reconnected the run, sealed the joints with mastic, and then performed source removal with HEPA-filtered negative pressure. Dust levels in the home dropped noticeably within days, and the basement room finally held temperature. That’s what a real cleaning does in Highlands Ranch. It finds the problem, fixes it, and shows you the proof.
If you’re in Highlands Ranch and your ducts haven’t been cleaned in years, call (806) 606-6902. You’ll get a written price before any work starts, a camera inspection as part of the job, and a Documented Photo Record when we leave. That’s how we’ve done it since 2013, and it’s what Highlands Ranch homeowners deserve.
