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.

Call (720) 799-2292 for a free written estimate.
We’ve been in Westminster homes since 2013, and the pattern is consistent: houses built between 1975 and 1995 make up the bulk of the housing stock, and most have never had their ductwork professionally cleaned. That decades-long gap between construction and the first service call is what defines our work here. The prairie dust from open Adams County land to the north, the Chinook winds that press it through every gap, and the wildfire seasons that have become routine rather than exceptional - all of it loads Westminster ductwork faster than systems in calmer climates. We don’t guess at what’s inside. We photograph it.
Why CleanRun Air Duct Cleaning Denver Is Westminster’s Preferred Air Duct Cleaning Company
Westminster homeowners find us the same way most people find any service now: they search, they read, and they look for what a company can show them rather than what it claims. We built our process around that behavior. Every job starts with a written price under Haven Standard Clause 1, and every job ends with a Documented Photo Record of every duct run - before and after - delivered as a standard part of the job record, not an upsell.
Our technicians are background-checked, uniformed, and identified by name before arrival. Haven Standard Clause 3: Verified Crews. The license number is published on this page. The equipment roster - Rotobrush, Nikro, Honeywell, and Aprilaire among others - is named here so customers can verify what will be used before agreeing to any price. The 365-Day Done Right Promise is backed in writing on every job, not stated in marketing copy and forgotten.
Dispatch and scheduling are coordinated from our Denver office, with crews serving Westminster locally. We don’t subcontract. We don’t send a different company in a different truck. The technician who quotes the work does the work, and the photos on the invoice match the ducts in that specific home.
Our Air Duct Cleaning Services in Westminster
Residential Duct Cleaning
Most Westminster residential calls come from the 1970s-1990s ranch-style and two-story tract homes along the US-36 corridor and around 92nd Avenue. These systems often have original fiberglass duct board plenums that fray internally over decades, releasing glass fibers into airflow if cleaned without first verifying structural integrity. Our process starts with a video inspection - we look before we touch. If the plenum is intact, we proceed with negative-pressure extraction using HEPA-filtered equipment. If it’s degraded, we document the finding and quote repair or replacement before any agitation begins.
Commercial Duct Cleaning
Westminster’s commercial base includes medical offices near Westminster Boulevard, retail along 120th Avenue, and professional buildings in the Orchard Town Center area. Commercial systems run longer hours and accumulate particulate on different schedules than residential. We quote commercial work by the system, not by the vent, with a written scope that specifies which runs will be accessed, which will be photographed, and what the deliverables are. The same Documented Photo Record applies: every run, before and after.
Supply Duct Cleaning
Supply ducts push conditioned air into living spaces, and in Westminster’s semi-arid climate they tend to accumulate fine mineral dust rather than the mold or mildew seen in humid regions. The supply side is also where we most often find disconnected or crushed flex duct runs in older homes - damage from storage in crawl spaces or attic work done by other trades. We photograph these conditions and include repair options in the written quote. No work proceeds without customer authorization.
Return Duct Cleaning
This is where Westminster’s housing stock gets specific. Return ducts pull air back to the air handler, and in many 1975-1995 Westminster homes, the return-air chase was framed directly into wood-stud walls with drywall acting as the duct surface. No metal liner. Decades of prairie dust, drywall particulate from construction, and accumulated debris cake the cavity. Standard duct-cleaning equipment can’t reach this. We make small access cuts, run agitation tools under negative pressure with HEPA filtration, then seal and patch. The alternative - leaving the dirtiest part of the system untouched - is what happens when crews don’t understand local construction methods.
In the 92nd Avenue corridor, our tech pulled a return grille in a 1983 ranch and found the chase was just unpainted drywall between studs - 40 years of prairie dust and drywall fines had compacted into a gray felt layer no shop vac could touch. We made two small access cuts, ran agitation tools through the cavity under negative pressure with HEPA filtration at the unit, then dropped a camera inspection to confirm the blower motor and air handler were finally breathing clean. The homeowner’s complaint of dust puffing from registers on windy Chinook days stopped within a week.

BeforeAfterTrusted Brands We Service in Westminster
Our equipment roster includes Rotobrush agitation systems, Nikro HEPA-filtered negative-air machines, Honeywell media air cleaners, and Aprilaire whole-home purifiers. These are trade-recognized brands, not proprietary equipment customers can’t research. We stock common replacement media and components for Westminster installations, which means filter changes and component swaps during a cleaning visit don’t require a return trip. If your system includes a Honeywell electronic air cleaner or Aprilaire media cabinet, we note the model during the initial inspection and verify fitment before the truck leaves the shop.
Common Air Duct Cleaning Problems We See in Westminster Homes
- Drywall-lined return chases in older homes. Found throughout the 1975-1995 build era, these wall cavities have no metal duct liner. Decades of accumulation require access cuts and specialized tools. Crews that skip this step leave the dirtiest part of the system untouched.
- Degraded fiberglass duct board plenums. Original plenums from the 1970s-1980s fray internally, and cleaning without first verifying structural integrity can release loose glass fibers into supply and return ducts. We inspect first. Always.
- Construction debris in newer master-planned homes. Bradburn and Legacy Ridge systems are under 20 years old with modern sheet metal, but many were never sealed or cleaned after build. Drywall scraps, wood chips, and fastener debris remain lodged in runs until a blower motor overheats or airflow drops enough to notice.
- Wildfire smoke particulate loading. The 2020 Cameron Peak and East Troublesome fires deposited measurable fine ash into Westminster HVAC systems. That ash doesn’t break down or flush out on its own. It accumulates on blower wheels and in filter media, reducing efficiency until it’s physically removed.
Pricing for Air Duct Cleaning in Westminster, CO
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts, and that price should be grounded in what the local market actually costs.
| Service | Typical Range in Westminster |
|---|---|
| Full residential system cleaning (single furnace, up to 12 runs) | $380-$680 |
| Return duct cleaning with wall access cuts | $180-$340 additional |
| Video inspection only (no cleaning) | $120-$180 |
| Commercial system cleaning (per air handler) | $520-$940 |
| Dryer vent cleaning (bundled with duct cleaning) | $95-$145 |
What moves a job within these ranges: the number of duct runs, accessibility (crawl space vs. basement), whether return chases require wall access, and the condition found during video inspection. A system with intact modern sheet metal in an unfinished basement costs less than the same square footage with drywall-lined returns and a cramped attic location. We don’t know which you have until we look. The estimate is free. The written price is firm once quoted. Call (720) 799-2292.

FAQs - Air Duct Cleaning in Westminster
Yes. Homes from this era in Westminster frequently have return-air chases framed into wood-stud walls with bare drywall as the duct surface, plus original fiberglass duct board plenums that may have degraded. We start with video inspection to verify plenum integrity, and we budget for wall access cuts on the return side. Call (720) 799-2292 and we’ll quote based on what your specific construction requires.
Yes, measurably. The Cameron Peak and East Troublesome fires produced weeks of hazardous AQI across the northern metro, and fine ash particulate entered homes through intake vents, gaps in building envelope, and standard HVAC operation. That ash accumulates on blower wheels and in duct runs. It does not degrade or flush out on its own. We document its presence during video inspection and remove it with negative-pressure extraction and HEPA filtration.
Because the return-air chase in many 1975-1995 Westminster homes is a wall cavity with no metal duct liner. Standard duct-cleaning equipment can’t navigate a stud bay. We make small, precise access cuts - typically 4-6 inches - to insert agitation tools under negative pressure, then patch and seal afterward. Skipping this step means leaving the dirtiest part of the system untouched. We photograph the cavity condition before cutting and include repair photos in the job record.
Westminster’s semi-arid climate and Front Range position mean fine mineral dust and agricultural particulate from open land in adjacent unincorporated Adams County infiltrate year-round. Chinook downslope wind events accelerate this by creating pressure differentials that pull outdoor air through every gap in the building envelope. Your HVAC system then concentrates that dust - pulling it through return grilles, trapping it in filters, and eventually loading duct surfaces. Cleaning removes the accumulation; sealing the duct system reduces future loading.
Because construction debris often remains in systems less than 20 years old if they were never cleaned after build. In Bradburn and Legacy Ridge, we’ve found drywall scraps, wood chips, fastener debris, and loose insulation in runs that look new from the outside. Modern sheet metal doesn’t degrade like 1980s duct board, but it doesn’t clean itself either. A blower motor overheating or reduced airflow at distant registers are common first symptoms. Video inspection confirms whether debris is present before any cleaning is quoted.
