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 Air Duct Cleaning Across Castlewood
Air duct cleaning in Castlewood, CO typically costs between $390 and $690 for a full system on a 2,000-square-foot home, with most jobs completed in a single four-to-six-hour visit.

Call (806) 606-6902 for a price that is set in writing before a single panel comes off.
Why CleanRun Air Duct Cleaning Is Castlewood’s Preferred Air Duct Cleaning Company
Castlewood is not Denver. The houses here were mostly framed and finished during Douglas County’s big suburban push in the 1990s and early 2000s, and that matters for ductwork. Builders left drywall dust, insulation fibers, and cut-offs of flex duct inside the runs at handover. Homeowners assumed new meant clean, so the debris stayed. Two decades later it has combined with the canyon’s fine clay dust into a compacted layer that standard vacuum noise won’t remove. We know this because our technicians document it. Every visit includes a camera inspection before work starts and a Documented Photo Record of every duct run after, so Castlewood customers see precisely what was removed.
Tomas Reyes, who leads our crews, started this company in 2013 on a simple rule: write the price down, show the evidence, and stand behind the work for a full year. That rule is the 365-Day Done Right Promise, and it is written on every Castlewood job, not just mentioned in marketing copy. When we arrive at a home off Castlewood Drive or near the canyon access roads, our technicians are background-checked, uniformed, identified by name, and operating under Haven Standard Clause 3: Verified Crews.
We answer the phone with a live person, not a menu. And we give Castlewood homeowners something the industry avoids: a Free Second Opinion on any written estimate. Bring us a competitor’s quote and we will put our number next to it in writing. If the price is not right, you keep the comparison and we leave no obligation behind.
Our Air Duct Cleaning Services in Castlewood

Our Air Duct Cleaning team covers the full range of residential and light commercial systems in Castlewood. These are the four services Castlewood homeowners ask for most.
Residential Duct Cleaning
Full system cleaning for forced-air homes throughout Castlewood, from the 1990s tract-home stock east of the canyon to the larger custom builds on larger lots. We run negative-pressure extraction with agitation tools, which means the ductwork is put under vacuum and the debris is physically broken loose and pulled out, not just stirred around. The price for a typical Castlewood home runs $390 to $690, written before work starts under Haven Standard Clause 1.

Commercial Duct Cleaning
Castlewood is mostly residential, but we do clean the few small commercial properties near the retail pads and office spaces that serve the community. Commercial pricing depends on system size and access, but a small office or retail unit in Castlewood typically runs $600 to $1,100. The same written-price rule applies and the same photo record is delivered to the property manager.

Supply Duct Cleaning
Supply ducts are the runs that carry conditioned air from the furnace or air handler to each register. In Castlewood we routinely find a hard, compacted layer of red-tan clay dust coating the inside of these runs, distinct from the gray dust typical of the broader Denver metro. That dust is characteristic of the decomposed Dawson Arkose formation around Castlewood Canyon and enters through leaky return-side connections. Standard vacuuming will not remove it. Source removal with rotating agitation brushes does. Expect supply duct cleaning as part of the full system price, not a separate charge.

Return Duct Cleaning
Return ducts pull air from your living space back to the blower. Castlewood’s persistent canyon winds push fine mineral dust against the exterior of homes, and any unsealed return-side connection becomes an entry point. Our crews document these leaks with the inspection camera, then clean and seal what is accessible. Return duct cleaning in Castlewood is where much of the chronic dust problem actually lives, which is why we treat it as a first-priority part of every full system job.

Full System Cleaning and Video Inspection
Full System Cleaning means supply runs, return runs, plenum, and the air handler. Video Inspection is the before-and-after record. We run the camera, show you the screen while it is happening, and then deliver the photo record as part of the standard job file. In Castlewood, that camera usually finds one of three things: original construction debris, red-tan dust accumulation, or wildfire smoke residue bonded to an existing dust layer. You see all three on screen before we touch anything. That is the difference between real work and an estimate written from the driveway.

Common Air Duct Cleaning Problems We See in Castlewood Homes

- Original construction debris still inside the runs. Most Castlewood homes were built between 1990 and 2005, when production builders rarely post-construction cleaned ductwork. Drywall dust, insulation fibers, and flex-duct scraps stay in the system for decades, hardening into a rough layer that attracts more dust.
- Red-tan clay dust from the Dawson Arkose formation. The canyon-edge exposure around Castlewood Canyon produces a fine, mineral-heavy dust that is visually distinct from Front Range gray dust. When our techs see it coating supply runs, it signals outdoor air infiltration through leaky return-side ductwork.
- Wildfire smoke residue bonding with existing dust. Castlewood sits in a smoke corridor during Colorado’s wildfire seasons. Combustion particulates settle onto existing dust and create a sticky, cement-like buildup that clogs air handler coils and cuts airflow in original duct systems.
- A persistent gritty film on registers despite regular filter changes. That film is the visible edge of a much larger accumulation upstream. Homeowners replace filters and still see dust on register faces within days. In Castlewood, that almost always traces to return-side leaks pulling canyon dust into the system.
Pricing for Air Duct Cleaning in Castlewood, CO
A full system cleaning for a typical Castlewood home runs $390 to $690. Larger homes with extensive duct runs run $700 to $950. Commercial spaces start around $600. What moves the number is system size, number of return drops, and the level of compacted buildup the camera shows. The price is written down before work starts. Always. That is Haven Standard Clause 1, and it has never had an exception since 2013. We also offer a Free Second Opinion: bring us a written estimate from any competitor and we will put our number next to it, in writing, on the spot.

FAQs - Air Duct Cleaning in Castlewood

The reddish-brown dust is fine mineral particulate from the decomposed Dawson Arkose formation exposed in Castlewood Canyon. The canyon-edge semi-arid exposure produces a clay-rich dust that is visually distinct from the typical gray household dust in the broader Front Range metro. When our techs find it inside your supply runs, it usually means outdoor air is entering through leaky return-side connections. Call (806) 606-6902 and we will show you exactly where the dust is coming from with a video inspection before any work begins.
If the ducts were never cleaned after construction, it is very likely that drywall dust, insulation fibers, and scraps of flex duct are still sitting inside the runs. Castlewood’s 1990s and 2000s production builders rarely post-construction cleaned ductwork before handover. The debris gets pulled into the system, compacts over time, and becomes part of the airflow problem. Our camera inspection shows you exactly how much is still in there. Call (806) 606-6902 to schedule an inspection and get a written price.
Yes. Castlewood sits in a smoke corridor during wildfire season, and smoke particulates enter through return duct leaks, exterior vents, and the natural negative pressure created by your blower motor. Those particulates bond with existing dust layers inside the ducts and form a sticky, cement-like buildup that clogs coils and reduces airflow. Keeping windows closed does not stop it. A full system cleaning removes the accumulated smoke residue, and sealing accessible return-side leaks reduces recurrence. Call (806) 606-6902 for an exact quote, written before any work starts.
The clearest signs are reddish-brown dust accumulating quickly on register faces, a gritty film you can feel on surfaces near supply vents, and a persistent musty smell when the blower motor first kicks on. In a 1998-built home off Castlewood Drive where the owners complained of exactly these symptoms, our camera inspection showed supply and return ducts lined with decades of red-tan clay dust mixed with drywall debris from original construction. We ran full negative pressure with agitation tools to break loose the compacted layer, then sealed the return-side leaks at the flex-duct connections. The register dust never came back that season. If that description matches your home, call (806) 606-6902 and we will verify it with a video inspection.
Only if the ductwork holds significant accumulated debris. A higher MERV filter will trap more particulates, but it cannot remove existing buildup from duct interiors. If the camera inspection shows compacted dust, construction debris, or hardened smoke residue, cleaning first makes sense. Then the higher MERV filter protects a clean system instead of a dirty one. Call (806) 606-6902 and we will show you on screen whether your Castlewood system needs cleaning before the filter swap. Estimates are free and written.
