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 Littleton
Air duct cleaning in Littleton, CO typically runs $380-$780 for a full residential system, with most jobs completed in a single visit and a written price delivered before any panel comes off. At CleanRun, we schedule Littleton homes from our Denver office and dispatch crews who know the difference between a downtown ranch on a crawl space and a two-story in Ken Caryl Ranch with original 1980s flex duct. We’re familiar with the long horizontal runs that slab-on-grade homes here require, the fine dust that 5,350 feet of elevation produces, and the wildfire smoke loading that settles into ductwork each summer. Call (720) 513-5159 for a written estimate, or keep reading to understand why Littleton’s conditions change how often you actually need this done.
Why CleanRun Air Duct Cleaning Aurora Is Littleton’s Preferred Air Duct Cleaning Company
We’ve served Littleton homeowners since adding the area to our route schedule in 2013, and the pattern is consistent: residents here research before they call, and they decide based on what we can show them, not what we claim. Our Air Duct Cleaning team arrives with documented credentials, background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and every technician is identified by name before arrival.
The 365-Day Done Right Promise applies to every Littleton job in writing, not as a policy subject to manager approval. If the work is not right, we make it right. That guarantee, combined with our Documented Photo Record on every visit, is why Littleton customers who initially found us through a Free Second Opinion on a competitor’s estimate often become repeat clients. They see the before-and-after images of every duct run, delivered as a standard job record, and they understand the difference between vacuum noise and actual source removal.
Dispatch and scheduling are coordinated from our Denver office, but crews serve Littleton locally and carry the full equipment roster: Rotobrush agitation systems, Nikro and Abatement Technologies negative-pressure extractors, and Honeywell filtration components. Parts are stocked for common Littleton systems, so turnaround on repairs or resupport work is same-visit when possible.
Our Air Duct Cleaning Services in Littleton

Residential Duct Cleaning
Littleton’s semi-arid air at 5,350 feet produces unusually fine dust that stays airborne far longer than in humid Midwest cities, so duct systems here load with particulate roughly twice as fast between cleanings. A typical residential cleaning in Littleton runs $380-$620 for a single-system home, with the final price set in writing before work begins under Haven Standard Clause 1. We use negative-pressure extraction (a vacuum system that pulls debris out while containing it, rather than blowing it around) combined with mechanical agitation from Rotobrush tools to dislodge buildup from the duct walls. Every run is photographed before and after.

Commercial Duct Cleaning
Littleton’s commercial base includes medical offices along Broadway, retail near the Aspen Grove shopping district, and professional buildings in the Denver Tech Center corridor that spills into the northeast part of the city. Commercial systems in Littleton typically range from $890-$2,400 depending on square footage, number of air handlers, and access complexity. We work after-hours to avoid disrupting operations, and the same Documented Photo Record applies: every trunk line and branch is imaged before and after source removal.

Supply Duct Cleaning
Supply ducts (the lines that carry conditioned air from your furnace or air handler to each room) in Littleton homes often show the heaviest loading at the far reaches of the system, particularly in Ken Caryl Ranch and Columbine Valley properties where 30-to-40-year-old flex duct has sagged at hangers. Supply-only cleaning runs $280-$450, but we flag this upfront: cleaning supply lines without addressing return-side contamination or sagged ductwork is incomplete work, and we won’t quote it that way without explaining why.

Return Duct Cleaning
Return ducts (the lines that pull air back to the HVAC unit for reconditioning) are where wildfire smoke particulate concentrates in Littleton homes. We were called to a 1980s two-story in Ken Caryl Ranch where the homeowner had sealed the house and run the HVAC all summer through wildfire smoke season - their return side was pulling ash straight off the blower motor. Camera inspection found sagged flex duct pocketing ash and construction debris at the joist hangers, and we had to resupport two runs before negative-pressure source removal and HEPA filtration could clear the system. After agitation tools worked the supply and return ducts and we swapped their filters to a proper MERV rating, airflow at the far registers jumped noticeably. Return-duct-focused cleaning starts at $320-$520; full system cleaning is typically the better value.

Full System Cleaning
Our most common request in Littleton, and the service we recommend for first-time customers. Full system cleaning covers supply ducts, return ducts, the plenum (the main distribution box connected to your furnace), registers, and the blower motor compartment. Pricing runs $380-$780 for typical Littleton homes, with the upper end reflecting larger square footage, multiple systems, or access issues like crawl-space runs. Every component is photographed. The written scope specifies what is included before work starts.

Video Inspection
We offer standalone video inspection for Littleton homeowners who want to see inside their ducts before deciding on cleaning, or who need documentation for a real estate transaction or insurance claim. Camera inspection is $180-$280 and includes a walkthrough of the findings with the homeowner present. In slab-on-grade ranch homes near downtown Littleton, this is particularly valuable: long horizontal runs through unconditioned crawl spaces often hide rodent intrusion or debris that a visual register check would miss.

AfterTrusted Brands We Service in Littleton
CleanRun technicians arrive with professional-grade equipment from trade-recognized brands: Rotobrush agitation systems for mechanical dislodging of debris, Nikro and Abatement Technologies for negative-pressure extraction, and Honeywell filtration components. We stock Guardsman sanitizing products for Littleton customers who request antimicrobial treatment after source removal. These are not proprietary tools - customers can look up each brand independently to verify specifications. Parts for common Littleton HVAC configurations are carried on every truck, so if a camera inspection reveals a separated duct joint or failed hanger in a Ken Caryl Ranch home, repair can often proceed same-visit rather than rescheduling.
Common Air Duct Cleaning Problems We See in Littleton Homes

- Wildfire smoke particulate embedding in ductwork. Littleton sits directly at the foot of the Front Range, making it one of the first Denver-metro communities blanketed when westerly winds carry smoke from Jefferson County’s foothills and Pike National Forest. Fine particulate penetrates standard filters and settles in duct runs, requiring source removal rather than just a higher MERV rating at the return grille.
- Sagged flex duct at joist hangers in 1970s-1990s homes. In Ken Caryl Ranch specifically, technicians routinely encounter original late-1970s and 1980s flexible ductwork that has sagged and kinked at joist hangers over 35-plus years, creating low-point pockets where wildfire ash and construction debris pool. Cleaning without resupporting these sections redistributes the debris the first time the blower ramps up.
- Long horizontal runs in slab-on-grade ranch homes. The prevalence of 1950s-1970s ranch-style homes near Littleton’s historic downtown means supply and return runs often snake through unconditioned crawl spaces. Rodent intrusion, dust accumulation, and moisture staining are common findings that a register-level visual check will miss entirely.
- Accelerated dust loading from semi-arid elevation. At roughly 5,350 feet, Littleton’s exceptionally dry air produces very fine, lightweight dust particles that stay airborne longer and penetrate deeper into duct systems than in lower, more humid markets. The result is accumulation that outpaces standard NADCA recommendations for more temperate climates.

FAQs - Air Duct Cleaning in Littleton

Every 2-3 years for most Littleton homes, compared to the 4-5 year interval typical in humid Midwest markets. The combination of 5,350-foot elevation producing ultra-fine dust, extended wildfire smoke season from May through October, and older housing stock with degraded ductwork means systems here load faster and need more frequent attention. Homes on unpaved roads or with significant open-land exposure may need annual inspection to determine interval. Call (720) 513-5159 and we’ll assess your specific conditions in writing.
Standard filters catch some particulate, but fine smoke particles pass through and embed in ductwork, particularly on the return side where air is drawn back to the blower. In Littleton, where westerly winds deliver smoke from Jefferson County and Pike National Forest directly into the community, we’ve camera-inspected systems where the filter appeared clean but the plenum and return trunk showed visible ash layering. Source removal is the only way to extract embedded particulate; filter upgrades alone redistribute it. We document this with before-and-after photos on every job.
Yes, but often only after repair. The original flex duct in Ken Caryl Ranch homes has typically sagged at joist hangers over 35-plus years, creating low points where debris pools. Cleaning without resupporting these sections leaves pockets that recontaminate the system immediately. We camera-inspect first, quote any needed resupport or replacement in writing, then proceed with source removal once the line can actually be cleared. The combined cleaning and repair typically runs $620-$1,200.
Slab-on-grade ranch homes common near downtown Littleton have long horizontal supply and return runs through unconditioned crawl spaces rather than basements. These runs are inaccessible without specialized equipment, often show rodent intrusion or moisture staining, and rarely reveal their condition from a register-level check. We use camera inspection to assess these lines before quoting, and our negative-pressure extraction system is designed to reach the full length of horizontal runs without disassembly.
NADCA (National Air Duct Cleaners Association) standards require source removal of contaminants, protection of the HVAC system during cleaning, and verification that the system is clean and operational before departure. In Littleton, where wildfire smoke adds a distinct contaminant category and older ductwork requires careful handling, NADCA-compliant methods ensure fine particulate is actually extracted rather than redistributed, and that fragile flex duct isn’t damaged by aggressive tools. CleanRun follows NADCA protocols on every job, documented with the photo record you receive at completion.
