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 Westminster
Air duct cleaning for a typical Westminster home runs $380-$620 for a full system, with most jobs completed in a single visit. Our crews are scheduled from our Denver office and carry Rotobrush and Nikro equipment directly to Westminster properties, including rural homes on unpaved roads east of 104th Avenue where prairie dust loads systems faster than standard metro intervals.
We’ve been driving these routes since 2013. We know the difference between a 1985 ranch off Church Ranch Boulevard with original fiberglass duct board and a 2019 build near Standley Lake with flex-duct runs that sag in crawlspaces. That local knowledge changes what equipment we load, what problems we expect to find, and what we tell you before we write a price. Call (720) 315-7291. Estimates are free, and the price you sign is the price you pay - Haven Standard Clause 1.
Why CleanRun Air Duct Cleaning Littleton Is Westminster’s Preferred Air Duct Cleaning Company
Westminster homeowners research before they call. They want to see what was found, not hear that it was “pretty dirty.” Our Documented Photo Record shows the inside of every duct run, before and after, as a standard deliverable on every job. No manager approval needed. No extra charge.
Our Air Duct Cleaning crews are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is written on every invoice, not just stated in a brochure. If the work isn’t right, we make it right.
We don’t do coupon pricing. A $79 “whole house special” can’t cover proper negative-pressure extraction with HEPA filtration, and Westminster’s double particulate load - plains dust plus foothill smoke - demands more than a shop vac and a brush. We put our written price next to any competitor’s quote with our Free Second Opinion.
Tomas Reyes has led CleanRun since its founding. The company remains independently owned and operated under the Haven Standard, with 52,000+ homes served and every one documented.
Our Air Duct Cleaning Services in Westminster
Residential Duct Cleaning
Westminster’s 1978-1998 suburban build-out left thousands of homes with fiberglass duct board rated for 25-30 years. That material is now delaminating in attics and crawlspaces across neighborhoods from Walnut Creek to Hidden Lake. Our residential service starts with a video inspection so you see the condition before we write a scope. We use Rotobrush agitation tools with negative-pressure extraction - the brush loosens debris while a vacuum maintains suction at the collection point, so nothing escapes into your living space.
Commercial Duct Cleaning
Westminster’s commercial corridors along 120th Avenue and Federal Boulevard include medical offices, retail, and light industrial with hybrid HVAC systems that mix older ductwork with newer equipment. We clean these with Abatement Technologies negative-air machines and document compliance-ready photo records for facility managers. Pricing for commercial systems in Westminster typically runs $1,200-$3,800 depending on square footage and access.
Supply Duct Cleaning
Supply ducts push conditioned air to your registers. In Westminster’s semi-arid climate, with relative humidity regularly at 15-25%, fine particulates cling electrostatically to supply duct walls. A standard vacuum pass misses this bonded layer. We use mechanical agitation - brushes, whips, or compressed-air tools depending on duct material - followed by HEPA-filtered extraction. For a typical Westminster ranch with 8-12 supply runs, supply-only cleaning runs $220-$340.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in Westminster they’re the entry point for both prairie dust from the east and wildfire smoke from the west. Return duct cleaning is where we most often find the gray-black ash that surprises homeowners who kept windows closed during smoke events. The return system was pulling contaminated air through leaky connections in unconditioned spaces the entire time. Return-only cleaning in Westminster typically runs $180-$290; we recommend pairing it with video inspection to locate those leaks.

Common Air Duct Cleaning Problems We See in Westminster Homes
- Fiberglass duct board delamination in 1980s-1990s tract homes. The binder holding fiberglass duct board together breaks down after 30 years. We open systems in Westminster neighborhoods built during the 1985-1995 boom and find loose fibers circulating in the air stream. Vacuuming the trunk line without addressing the failing board leaves a continuing source of particulate.
- Electrostatic particulate bonding in low humidity. Westminster’s 15-25% relative humidity creates static charge inside metal ductwork. Fine dust, pollen, and wildfire ash adhere to walls instead of moving toward the filter. Standard brush-and-vac without agitation tools leaves a bonded layer that re-releases when humidity shifts.
- Sagging flex-duct in western Westminster crawlspaces. Newer developments near Standley Lake use flex-duct runs that develop sags and gaps at connections. These trap debris and create bypass paths that pull unfiltered air from crawlspaces. Cleaning without sealing means re-contamination within a season.
- Post-wildfire ash accumulation in return systems. The 2021 Marshall Fire corridor generated demand waves that hit Westminster harder than most northern metro cities. We still find gray-black fine ash in returns years later, particularly in homes with crawlspace duct runs that pulled smoke-laden air through leaks while windows stayed closed.

FAQs - Air Duct Cleaning in Westminster
Every 2-3 years, not the 3-5 year standard interval. The prairie dust load from unpaved roads and open eastern land measurably increases particulate accumulation in return systems, and Westminster’s low humidity electrostatically bonds that dust to duct walls. Call (720) 315-7291 and we’ll inspect your system and put a recommended interval in writing.
It may be. Fiberglass duct board was common in Westminster’s 1978-1998 build-out and is rated for roughly 25-30 years. At 35-40 years old, many of these systems are delaminating and shedding fibers into the air stream. Our video inspection shows you the condition before we write any scope or price.
Westminster sits at a geographic pinch point. Upslope winds carry prairie dust from the eastern plains; wildfire smoke funnels down from the foothills to the west. Cities 10 miles in either direction don’t face both sources equally. That double load, combined with 30-40 year old fiberglass duct board still in service, makes Westminster systems measurably more contaminated.
Source removal: mechanical agitation to loosen debris, negative-pressure extraction to contain it, and HEPA filtration so nothing escapes into your living space. For Westminster’s typical bonded particulate, we add aggressive agitation tools - brushes, whips, or compressed-air devices - because vacuum suction alone won’t release electrostatically clung dust. Every run is photographed before and after.
Your HVAC return system pulled smoke-laden air through leaky duct connections in unconditioned crawlspaces and attics. Windows closed doesn’t mean the building envelope was sealed. We recently worked a ranch home near Standley Lake where the homeowner had kept windows shut through two smoke seasons but still saw gray-black ash coating the return registers. Our tech ran a camera inspection and found sagging flex-duct runs in the unconditioned crawlspace pulling smoke-laden air past leaky connections; after source removal with agitation tools under negative pressure and HEPA filtration, we sealed the gaps and the blower motor amp draw dropped noticeably. Video inspection finds these breaches. Call (720) 315-7291.
