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.
Fast, Reliable HVAC Cleaning Across Castlewood
HVAC cleaning in Castlewood typically costs $450-$900 for a full system clean on a 2,000-3,500 sq ft home, and most jobs are completed in a single visit. CleanRun Air Duct Cleaning has been documenting the inside of Castlewood ductwork since 2013, and what we find here is different from anywhere else in the metro. The red-tan clay dust from the Dawson Arkose formation around Castlewood Canyon works its way into return-side ductwork and coats evaporator coils in a film that standard filter changes never touch. If you’re noticing weak airflow, a dusty smell when the heat kicks on, or registers that look dusted even after cleaning, call (806) 606-6902. We’ll give you a written price before a single panel comes off.
Why CleanRun Air Duct Cleaning Is Castlewood’s Preferred HVAC Cleaning Company
We didn’t start as a marketing company that happens to clean ducts. CleanRun has been running cameras through Castlewood ductwork since 2013, and every job ends with a documented photo record of every run we touched. Homeowners in Castlewood Pines, the Village at Castlewood, and the neighborhoods off Castlewood Canyon Road tell us the same thing: they picked us because we showed them what was actually in the ducts before we asked for a signature.
Our crews operate under the H.A.V.E.N. Standard. Haven Standard Clause 1 means a written price before any work starts. Clause 3 means background-checked, uniformed technicians identified by name before they step onto your property. We’re not vague about either. Every Castlewood job gets the same treatment whether the home is a 1994 tract build off Franktown Road or a newer place near the Canyon entrance.
Tomas Reyes, who leads our team, has always pushed the same practice: photograph the plenum, the register, the coil, and the blower wheel before and after. If you’re researching HVAC cleaning companies in Castlewood, that’s the standard you should hold anyone to. Dispatch and scheduling are coordinated from our Denver office, and our crews serve Castlewood locally.
Our HVAC Cleaning Services in Castlewood

Evaporator Coil Cleaning
Castlewood’s semi-arid climate means fine clay dust coats evaporator coils faster than in wetter parts of the metro. A coil caked in Dawson Arkose fines can’t transfer heat efficiently, so your system runs longer to hit the same thermostat setting. We clean coils with professional-grade equipment from Nikro and Rotobrush, then document the before and after on camera. Typical evaporator coil cleaning in Castlewood runs $250-$450 as part of a full system clean.

Blower Cleaning
The blower wheel is where Castlewood’s dust does its slowest damage. In the 1998-era systems we see throughout the community, blower motors have been spinning in drywall dust and red-tan clay fines since original construction. That grit grinds against motor bearings and unbalances the wheel. We remove the blower assembly, clean each blade, and photograph the result. Blower cleaning in Castlewood typically runs $200-$350 when bundled with full-system HVAC cleaning.

Condenser Cleaning
Your outdoor condenser sits in the path of Castlewood’s persistent winds off the Front Range. Cottonwood debris, clay dust, and wildfire particulate build up between the fins and choke airflow across the coil. A dirty condenser makes the compressor work harder and shortens its life. We clean the condenser coil, straighten bent fins where possible, and check the refrigerant line for signs of wear. Condenser cleaning in Castlewood runs $150-$300.

Air Handler Cleaning
Most of what we find in Castlewood air handlers is construction-era debris that never left. Drywall dust, insulation fibers, and clay fines settle into the cabinet, the filter rack, and around the coil. On a 2002 build near the Canyon, we pulled enough gypsum dust from the air handler to fill a 2-gallon bucket. Air handler cleaning runs $200-$400, and we recommend it as part of any full-system job because a clean duct system feeding a dirty air handler just re-contaminates itself.

Common HVAC Cleaning Problems We See in Castlewood Homes

- Builder-era debris in 1990s flex-duct runs: Most Castlewood tract homes were built before post-construction duct cleaning was common practice, and the original flex-duct runs have never been opened. We regularly find drywall dust and insulation fibers packed behind the first bend of supply runs, where they stay until negative-pressure extraction pulls them out.
- Red-tan Dawson Arkose clay dust: This is the signature Castlewood contaminant. The decomposed sandstone soils around Castlewood Canyon blow fine clay particles into leaky return ducts, where they bond with existing dust layers and form a crust that standard brush agitation alone won’t break loose. It takes negative-pressure extraction with HEPA filtration to remove it completely.
- Wildfire smoke particulate accumulation: Castlewood sits in a smoke corridor during Colorado’s fire season, and fine combustion particulates bind to the dust already coating your ducts. A system that accumulated 20 years of clay dust then gets a few seasons of smoke loads becomes a serious air quality problem inside the home.
- Leaky return-side ductwork: The flex duct used in 1990s Castlewood builds loses sealant at the joints over time. Once a return-side joint opens, the blower pulls attic air, crawlspace air, and whatever is floating in it directly into the system. We can identify these leaks during cleaning and seal them so the problem doesn’t return within months.

FAQs - HVAC Cleaning in Castlewood

Because the builders’ subcontractors may have sealed the registers but drywall sanding still forces fine gypsum dust through gaps in the duct runs, where it settles behind the first bend and never gets pushed out by normal airflow. A post-construction cleaning removes this debris before it gets baked onto the blower motor and evaporator coil. If you just closed on a Castlewood build, call (806) 606-6902 and we’ll run a camera through your ducts before you move a single box in.
The red-tan Dawson Arkose clay fines that blow off Castlewood Canyon coat the coil and act as an insulating layer, reducing heat transfer and forcing longer run times. Inside the air handler, the same clay dust mixes with construction debris to form an abrasive paste that wears blower bearings. One thorough cleaning restores coil efficiency and removes the grit so you’re not looking at a premature blower motor replacement.
Yes, you’ll see it on camera before we touch anything. We run an inspection scope through your supply and return runs and walk you through the footage in real time. When we find 3 inches of gypsum dust at the first elbow and clay fines coating the plenum, you’ll see exactly what we’re talking about. Then the before and after photo record becomes part of your job documentation.
Castlewood’s semi-arid terrain and position beside Castlewood Canyon expose homes to persistent fine clay dust that the rest of the metro doesn’t get in the same volume. Add 20-30-year-old flex-duct runs that were never post-construction cleaned and a wildfire smoke corridor, and you have a combination that produces some of the most heavily contaminated ductwork we document anywhere in the Front Range.
If the builder can’t produce a documented photo record of the inside of every duct run, they didn’t do it. Construction dust doesn’t show up in a walkthrough, but it shows up in airflow problems and premature blower wear months later. We offer a Free Second Opinion on any written estimate, including a builder’s scope of work. Bring us what they gave you, and we’ll put our own documented findings next to it.
