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 Air Duct Cleaning Across Castle Rock
Air duct cleaning in Castle Rock typically costs between $425 and $780 for a full system on a 2,500 to 4,500 sq ft home, and most jobs are completed in one afternoon. The real question isn’t whether your ducts need attention after a decade or two of Palmer Divide winds, it’s whether the company you hire can show you what was actually inside them. We can. Every job includes a documented photo record of every duct run before and after, so you see exactly what you paid for. If you’re noticing dust settling on registers within days of cleaning, or you’ve never had your ducts touched since buying a home in The Meadows or Terrain, call us at (806) 606-6902. Tomas Reyes and our Castle Rock crews bring professional-grade Rotobrush and Nikro equipment to every job, with a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Castle Rock’s Preferred Air Duct Cleaning Company
Castle Rock homeowners don’t respond to coupon mailers. They research. That’s why our approach here has always been evidence-first: we photograph the inside of every duct run before we touch it, and we photograph it again when we’re done. The homeowner keeps that record. It’s not a marketing gimmick; we’ve done it since our first job in 2013, and we’ve now served over 52,000 homes. The H.A.V.E.N. Standard governs every visit: written pricing before work starts (Clause 1), background-checked and uniformed technicians identified by name (Clause 3), and the 365-Day Done Right Promise, in writing, on every job. If something isn’t right, we make it right. That’s the entire point.
We also know Castle Rock specifically. Our crews are familiar with the flex-duct layouts in Plum Creek, the zoned systems in Founders Village, and the fine grit problem that plagues eastern subdivisions like Cobblestone Ranch. Dispatch is coordinated from our Denver office, but the technicians cleaning your ducts live and work in the Castle Rock area. You won’t wait days for a callback, and you won’t get a crew that has to ask you where Founders Parkway is.
Our Air Duct Cleaning Services in Castle Rock
We clean the entire system, not just the registers. Here’s what that means in a Castle Rock home, where long flex-duct runs and multi-zone setups are the norm.
Residential Duct Cleaning
Most Castle Rock homes fall between 2,500 and 4,500 square feet, built in subdivision phases from the late 1990s through the 2010s. Those homes have long flex-duct runs serving three, four, sometimes five zones. Debris accumulates at elbows and transitions, not evenly along the run. Our residential service uses negative-pressure extraction with HEPA filtration, pulling debris out rather than blowing it around. We clean every supply and return run, plus the plenum, blower compartment, and registers. A full residential job in Castle Rock runs $425 to $780 depending on square footage and system complexity. You get the written price before a single panel comes off.
Commercial Duct Cleaning
Castle Rock has a growing commercial corridor along Founders Parkway and around the Outlets, plus medical offices, dental practices, and small retail throughout downtown. These spaces often share HVAC infrastructure and run systems far more hours per day than residential units. We schedule commercial work in Castle Rock around your operating hours, not ours, and the same documented photo record applies. Commercial pricing depends on system size and access, but a typical single-tenant office or retail space in Castle Rock runs $900 to $2,200. Written quote first, always.
Supply Duct Cleaning
Supply ducts carry conditioned air from your air handler out to every room. In Castle Rock, supply ducts pull in whatever the blower pushes, which means the finest particulates from the Palmer Divide winds end up coating the walls of these runs first. We see it constantly in Terrain and Crystal Valley: a fine reddish-tan film that thickens over time. Cleaning supply ducts properly means agitating the buildup mechanically, not just vacuuming through a register. We use Rotobrush agitation tools under negative pressure so dislodged debris is captured, not pushed into your living space. Supply-only cleaning in Castle Rock typically runs $225 to $400 depending on the number of runs.
Return Duct Cleaning
Return ducts are the unglamorous half of the system, and they’re the half most homeowners never see. That’s a mistake. In Castle Rock’s windy, semi-arid environment, return ducts accumulate debris faster than supply ducts because they pull directly from the home’s intake points, which are pulling in dust from open land, unpaved roads, and construction grading. Skipping the return side leaves your system unbalanced and half the debris still in the loop. Return duct cleaning in Castle Rock runs $200 to $375 depending on runs and access. We clean both sides. Always.
Full System Cleaning
This is the service we recommend for most Castle Rock homes, especially those built between 1995 and 2015 that have never had ducts cleaned. Full system cleaning covers supply and return ducts, the plenum, blower, coils (if accessible), and registers. It’s the only way to actually reset your system rather than partial-clean it. For a 3,000 sq ft two-story in The Meadows, plan on $550 to $720. For a 4,500 sq ft multi-zone home in Terrain, you’re looking at $680 to $780. The written quote we provide before starting is the price you pay. No per-vent pricing, no add-ons discovered mid-job.
Video Inspection
Before we clean, we inspect with a camera. Not just because it documents the before state, but because Castle Rock systems have specific failure patterns, collapsed flex runs, disconnected joints, rodent intrusion in outbuildings, that you need to know about whether or not you proceed with cleaning. Video inspection is part of every full system cleaning at no extra charge. If you want an inspection without cleaning, that’s $129, and the footage is yours to keep.

BeforeAfterTrusted Brands We Service in Castle Rock
Castle Rock homes run a mix of builder-grade and upgraded HVAC equipment, and we service all of it. We work on systems with Honeywell controls, Aprilaire filtration, and Guardsman components, among others. We also service and clean systems where filtration has been retrofitted, which is common in Castle Rock homes where homeowners have tried to combat the dust issue with aftermarket filters. We stock common filters and replacement components for these brands on our trucks, so if we find a clogged filter or a worn component during cleaning, we can address it that day. No second visit, no waiting on parts. The brands we use on the cleaning side, Rotobrush, Nikro, and Abatement Technologies, are trade-recognized names you can look up independently before we arrive. That’s the point of naming them.
Common Air Duct Cleaning Problems We See in Castle Rock Homes
- The reddish-tan grit signature. Castle Rock sits on iron-rich Douglas County soil. Spring winds suspend those fine particulates and pull them into HVAC intakes. We see the same reddish-tan coating in nearly every system east of I-25, from Crystal Valley to Cobblestone Ranch. It’s a Castle Rock signature, and it shortens the realistic cleaning interval from 5-7 years down to 3-4 in many eastern subdivisions.
- Long flex-duct runs accumulating at elbows. The production-built homes in The Meadows, Plum Creek, and Terrain feature extended flex-duct runs to serve multiple zones across large footprints. Debris doesn’t distribute evenly; it builds at the first elbow after the plenum and at transition points. That’s exactly where our camera finds the thickest buildup.
- Construction dust from active subdivisions. Castle Rock is still expanding, and if you live near active grading or a new phase being platted, your ducts are pulling in more than the baseline wind-blown particulates. New construction dust is finer and more pervasive than standard household dust, and it works its way into the blower compartment quickly.
- Skipped return ducts from previous cleanings. We regularly follow up after a different company cleaned only the supply side. The homeowner reports no improvement because the return side, where Castle Rock systems accumulate the most debris, was never touched. A partial clean is a wasted invoice. We clean both sides every time, and the after photos prove it.
Pricing for Air Duct Cleaning in Castle Rock, CO
Here’s the honest range for Castle Rock’s market. A single system (one furnace/air handler) in a 2,500 to 3,500 sq ft home runs $425 to $625 for full system cleaning. A larger 3,500 to 4,500 sq ft home with multiple zones runs $550 to $780. If you have two systems, which is common in bigger Castle Rock homes, you’re looking at $700 to $1,100 total. What affects cost: square footage, number of duct runs, number of systems, and access (crawlspaces and tight mechanical rooms add labor). What doesn’t affect cost: the condition inside your ducts. We don’t price based on how dirty they are. You get the written price before work starts, and that’s the price. Always. Haven Standard Clause 1.

FAQs - Air Duct Cleaning in Castle Rock
Every 3 to 4 years for most Castle Rock homes, especially those east of I-25 near open parcels or active construction. The Palmer Divide creates persistent wind that suspends fine soil particulates year-round, and spring gusts over 50 mph accelerate the buildup. Homes in the western foothills or more sheltered neighborhoods may stretch to 5 years, but if you’re near Cobblestone Ranch, Crystal Valley, or any active grading, 3 years is realistic. Call (806) 606-6902 and ask for a camera inspection; the footage will tell you exactly where you stand.
Yes, wood heat adds fine ash and creosote particulates to the indoor air stream, and in homes where the fireplace or stove shares return air pathways, that material gets pulled into the ductwork. Rural Castle Rock properties that burn wood regularly will see faster particulate buildup on ducts, especially on the return side. We account for this in our cleaning schedule recommendations, not with an upcharge, but with a realistic interval. We cleaned a 3,800 sq ft two-story in the Terrain neighborhood where the supply and return ducts were coated with the distinctive reddish-tan grit from the adjacent graded lots; our camera inspection showed buildup over an inch thick on the return side. Using Rotobrush agitation tools under negative pressure and HEPA filtration, we completed source removal in a single afternoon, and the homeowner reported noticeably less dust on registers within days.
Two reasons. First, if your return ducts were skipped or only partially cleaned, dust from the return side keeps re-entering circulation immediately after cleaning. Second, Castle Rock’s semi-arid, windy conditions mean your home pulls in more airborne particulate than lower-elevation suburbs, so even a properly cleaned system will accumulate surface dust on registers faster. If you’re seeing heavy dust within weeks, not months, call us at (806) 606-6902 and we’ll camera-inspect to see what’s actually going on. Most often, it’s an un-cleaned return side from a previous partial job.
Yes. Many rural Castle Rock properties have detached shops, garages, or outbuildings with their own HVAC or ventilation systems. These spaces accumulate dust, wood debris, and sometimes rodent intrusion at a faster rate than the main house. We clean those systems with the same equipment and the same documented photo record. Pricing for outbuilding systems depends on the number of runs and access, but a typical shop or detached garage in Castle Rock runs $250 to $450. The written quote is still the written quote, no exceptions.
That’s the iron-rich soil particulate from Douglas County’s undeveloped land, and it’s the single most common thing we find in Castle Rock duct systems. The Palmer Divide’s wind events suspend fine reddish-tan soil and pull it into your intake, where it settles and bonds to duct surfaces. It’s harmless from a toxicity standpoint, but it’s abrasive, and over time it cakes onto the blower motor and coils, reducing system efficiency and pushing the blower to work harder. The fix is source removal, not surface vacuuming, which is why we use mechanical agitation under negative pressure. If you can see it on your registers, it’s far thicker deeper in the runs. Call (806) 606-6902 for a free camera inspection and a written quote.
