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.
Trusted Air Duct Cleaning for Denver Homeowners
Air duct cleaning in Denver typically costs $450-$850 for a complete residential system and takes 3-5 hours from arrival to final photo documentation. CleanRun Duct Repair & Cleaning has served more than 52,000 homes since 2013, every job starting with a written price and ending with a Documented Photo Record of every duct run. Call (720) 799-2292 for a free estimate with no obligation to book.
Denver’s semi-arid climate, high altitude, and seasonal wildfire smoke create a specific debris profile inside ductwork. Dust from the Front Range foothills settles in return plenums (the main collection chamber where air enters the system). Pollen from the South Platte River corridor accumulates at register elbows. During summer fire season, fine particulate matter filters through even closed windows and deposits in supply runs (the pathways that push conditioned air into rooms). We’ve photographed these patterns in homes from Air Duct Cleaning in Denver to Thornton to Highlands Ranch. The buildup is real, it is measurable, and it affects how your HVAC system performs.
Our crews operate under the H.A.V.E.N. Standard, with Haven Standard Clause 1 requiring a written price before any work begins. No exceptions. Haven Standard Clause 3, Verified Crews, means every technician is background-checked, uniformed, and identified by name before arrival. Tomas Reyes established this protocol in 2013 after observing how the duct cleaning industry relied on verbal estimates that ballooned once the truck was in the driveway. The 365-Day Done Right Promise applies to every job, backed in writing, not subject to manager approval.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential Duct Cleaning covers the complete network of supply and return pathways in single-family homes, townhomes, and condominiums up to four units. In Denver’s older neighborhoods like Berkeley and Congress Park, we regularly find original galvanized ductwork from the 1950s with debris layers two to three inches thick at the plenum connection. Our process uses negative-pressure extraction (a vacuum system that pulls contaminants out while preventing their release into living spaces) combined with mechanical agitation from Rotobrush equipment. Every residential job concludes with a Documented Photo Record showing the interior of each duct run before and after cleaning, delivered as part of the standard job record.

Commercial Duct Cleaning
Commercial Duct Cleaning serves office buildings, retail spaces, restaurants, and multi-unit residential complexes throughout the Denver metro area. Commercial systems differ from residential in scale, access requirements, and code compliance - Denver’s building department requires post-cleaning documentation for certain occupancy types, particularly food service and healthcare-adjacent facilities. We schedule commercial work to minimize operational disruption, often performing cleaning during overnight hours or weekends. Our crews use Nikro and Abatement Technologies equipment sized for larger-diameter trunk lines and extended duct runs found in commercial plenums. The same written-price protocol and photo documentation apply; commercial clients additionally receive a scope summary suitable for insurance or regulatory filing.

Supply Duct Cleaning
Supply duct cleaning addresses the pathways that deliver conditioned air from your HVAC unit into individual rooms. These runs are pressurized during system operation, meaning any debris they contain is actively distributed into living spaces. In Denver homes with evaporative cooling (swamp coolers) converted to central air, we frequently find mineral scale and algae residue in supply lines near the former cooler location, particularly in neighborhoods like Villa Park and Westwood. Supply duct cleaning requires careful register removal and protective covering of finished surfaces - Haven Standard Clause 7, Property Respect, governs this protocol. We photograph each supply run from the register opening inward to document baseline conditions and final results.

Return Duct Cleaning
Return Duct Cleaning targets the pathways that pull air back to the HVAC unit for reconditioning. Because return ducts operate under suction, they accumulate the heaviest debris loads - pet hair, skin cells, cooking particulate, and outdoor dust drawn through gaps in building envelope. In Denver’s newer construction, particularly in Stapleton and Lowry redevelopment areas, we’ve documented return plenums packed with construction debris left by original builders: drywall dust, wood shavings, and insulation fragments. Return duct cleaning is often the most visually dramatic component of a full system service. The photo record typically shows the starkest before-and-after contrast here.

Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, the plenum, registers, grilles, and the accessible surfaces of the HVAC unit itself - blower motor, evaporator coil (the heat-exchange component that cools air in summer), and cabinet interior. This is the service we recommend for first-time CleanRun customers and for homes that have never had documented duct cleaning. In Denver’s climate, where heating runs six months and cooling runs three, a full system cleaning addresses the complete debris cycle. The written price for a full system cleaning is all-inclusive; we do not add per-vent charges or equipment-access fees after arrival. What we quote is what you pay.

Video Inspection
Video inspection uses a borescope camera - a flexible, lighted instrument - to examine duct interiors without disassembly. We offer this as a standalone service for homeowners who want to verify whether cleaning is necessary, and as a preliminary step before quoting complex commercial or historic residential systems. In Denver’s Capitol Hill and Cheesman Park neighborhoods, where homes often have modified or non-standard duct configurations, video inspection prevents surprises and allows accurate written pricing. The video file becomes part of the job record, alongside the still photo documentation. A standalone video inspection in Denver runs $150-$250 and includes a written findings summary with recommended next steps if cleaning is indicated.

Brands We Service for Air Duct Cleaning

CleanRun crews are trained on equipment from Honeywell, Aprilaire, and Rotobrush, among other trade-recognized manufacturers. We’ve serviced hundreds of Honeywell electronic air cleaners integrated into Denver-area HVAC systems, particularly in homes built during the 2010-2018 construction boom in Stapleton, Green Valley Ranch, and Reunion. These units require specific handling during duct cleaning to avoid damage to ionizing wires and collector cells. Our crews document the condition of integrated air cleaning components as part of the standard photo record.
Aprilaire whole-house humidifiers, common in Denver installations due to our dry climate, are inspected for proper drainage and microbial growth during full system cleaning. We’ve replaced deteriorated water panels and cleaned mineral-deposited distribution trays in hundreds of homes from Air Duct Cleaning in Greenwood Village to Arvada. Whether your system includes Honeywell, Aprilaire, Rotobrush-compatible components, or any other make, we can service it. Our Free Second Opinion on Any Written Estimate applies to brand-specific recommendations too - bring a competitor’s quote that specifies equipment replacement, and we’ll put our assessment next to it in writing.
Before
AfterSigns You Need Air Duct Cleaning Right Now
- Visible dust emission from registers when the system starts. If a puff of particulate exits your supply registers at blower startup, the supply ducts contain loose debris that the air stream is mobilizing. This is not normal; properly cleaned ducts should not discharge visible material. The debris source is typically accumulation at register elbows or in the plenum, both addressable through professional cleaning with negative-pressure extraction.
- Uneven heating or cooling across rooms with no ductwork modifications. When a previously balanced system develops hot or cold spots, restricted airflow from debris buildup is a common cause. In Denver’s older ranch homes in Glendale and Cherry Hills Village, we’ve restored even airflow by removing debris blockages at duct transitions that reduced delivery to distant rooms by 40% or more.
- Persistent musty or stale odor when HVAC operates. Odors indicate microbial growth on debris substrates or in standing water near the evaporator coil. Denver’s low humidity generally suppresses mold, but swamp cooler conversions and humidifier malfunctions create localized moisture. Cleaning removes the organic material that supports odor production; sanitizing addresses residual microbial contamination.
- Increased frequency of filter clogging beyond seasonal norms. A filter that loads in two weeks instead of two months is capturing debris that should not be circulating - debris that entered the return duct upstream of the filter location. This pattern indicates return pathway contamination that bypasses or overwhelms standard filtration.
- Recent renovation or construction activity without post-project duct cleaning. Construction dust is fine, abrasive, and voluminous. Even with protective measures, drywall dust and particulate from flooring, painting, or demolition enter return pathways. In Denver’s active renovation market, particularly in Berkeley and Highland, we recommend duct inspection after any project involving wall penetration or significant dust generation.
Our Air Duct Cleaning Process - Step by Step

- 1
Written price delivered before work begins. Haven Standard Clause 1 requires that every customer receive a written, itemized price before any panel is removed or equipment is activated. For a typical Denver home, this price ranges from $450-$850 depending on system size, accessibility, and contamination level. The price does not change after delivery unless you request additional services.
- 2
Protective setup and access preparation. Technicians lay protective covering on floors and furniture near all work areas. Registers and grilles are removed with care for painted or finished surfaces. In Denver’s historic homes with original woodwork, we use non-marring tools and document pre-existing condition with photos.
- 3
Video or photo documentation of baseline conditions. A borescope camera or high-resolution still camera is inserted into each duct run to record pre-cleaning conditions. These images are time-stamped and become part of the Documented Photo Record included on every visit. Customers see what we saw before any cleaning begins.
- 4
Mechanical agitation and negative-pressure extraction. We deploy Rotobrush contact cleaning for duct interiors, combined with high-volume vacuum extraction from Nikro or Abatement Technologies portable collection units. The negative-pressure configuration ensures dislodged debris is captured at the point of disturbance, not released into your home. Supply and return runs are cleaned sequentially, with the plenum addressed last.
- 5
Post-cleaning photo documentation and system verification. Every duct run is re-photographed to verify cleaning completeness. Registers are reinstalled, protective covering is removed, and the HVAC system is operated through a complete cycle to confirm normal function. The photo record, written scope summary, and 365-Day Done Right Promise documentation are delivered before the crew departs.
How Much Does Air Duct Cleaning Cost in Denver?
A typical residential full system cleaning in Denver runs $450-$850. A partial service focused on supply or return ducts only runs $280-$450. Commercial systems start at $800 and scale with square footage and access complexity. Video inspection as a standalone service is $150-$250. These ranges reflect actual quotes delivered in writing to Denver-area homeowners during 2023-2024.
Several factors move a quote within or above these ranges. System size is the primary variable: a 2,000 square foot home with 12-15 registers requires less time than a 4,000 square foot home with 25+ registers. Accessibility matters - ductwork in finished basements or behind drywall requires additional access work. Contamination level affects time and disposal requirements; heavy construction debris or pest intrusion adds steps. Location within the metro area does not affect pricing; we do not charge mileage premiums for service to Thornton, Aurora, or Air Duct Cleaning in Englewood.
To avoid overpaying, reject any quote that lacks written confirmation or that advertises a per-vent rate. The industry’s bait-and-switch model relies on a low entry price - often $79-$149 - that expands dramatically once the technician is inside your home. CleanRun does not participate in this practice. Our written price is the price you pay. We also offer a Free Second Opinion on Any Written Estimate: bring a competitor’s written quote, and we’ll put our number next to it with no obligation.
Every estimate includes the complete scope of work, the equipment to be used, the photo documentation deliverable, and the 365-Day Done Right Promise. There are no additional fees for disposal, equipment setup, or photo delivery. Call (720) 799-2292 for a free estimate - we’ll provide a written price range based on your system description, confirmed in person before any work begins.

Frequently Asked Questions - Air Duct Cleaning in Denver

Air duct cleaning is the mechanical removal of accumulated debris from the interior surfaces of HVAC ductwork, including supply runs, return runs, plenums, and registers. It removes dust, pollen, pet dander, skin cells, construction debris, and in some cases microbial growth - the material that circulates through your home when the system operates. CleanRun’s process captures this debris using negative-pressure extraction rather than redistributing it; the photo record shows exactly what was removed from your specific system.
A typical residential full system cleaning takes 3-5 hours from arrival to final documentation. Partial services or smaller homes may finish in 2.5 hours; large homes with complex access or heavy contamination may extend to 6 hours. Commercial projects are scheduled with time estimates based on square footage and system configuration. We do not rush the documentation phase - the photo record is completed for every run, every time. Call (720) 799-2292 to schedule; we’ll confirm expected duration when delivering your written price.
Residential full system cleaning in Denver typically costs $450-$850, with partial services at $280-$450 and commercial systems starting at $800. The final written price depends on system size, register count, accessibility, and contamination level - not on how long the crew spends on site. CleanRun quotes one flat price per system, agreed before work starts, with no per-vent add-ons or post-arrival upsells. Call (720) 799-2292 for a free estimate with exact pricing for your home.
Yes. CleanRun crews are trained on Honeywell, Aprilaire, and Rotobrush equipment, and we service all major HVAC and air quality brands installed in Denver-area homes. We stock common replacement components for integrated air cleaners and humidifiers, and we document the condition of brand-specific equipment as part of the standard photo record. If your system includes specialized components, we’ll note them in the written scope and price any recommended service separately - never as a surprise.
We do not advertise same-day or emergency dispatch for air duct cleaning. Duct cleaning is a scheduled, planned service - it does not address acute HVAC failures that require immediate repair. If your system has stopped working entirely, we recommend contacting an HVAC repair contractor first; once operational, we can assess and clean the ductwork. For urgent air quality concerns following water damage or pest intrusion, call (720) 799-2292 and we’ll prioritize scheduling within our next available opening, typically 1-3 business days.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right. This is a written guarantee delivered with every job record, not a policy subject to manager approval. Haven Standard Clause 1 governs pricing accuracy; Haven Standard Clause 6 governs workmanship accountability. If you observe debris discharge, odor recurrence, or airflow issues within 365 days of service, we return to assess and correct at no charge. The photo record from your original service provides the baseline for any warranty evaluation.
Clear a path to all registers and the HVAC unit location; remove fragile items from shelves near work areas; and secure pets in a separate room. You do not need to cover furniture or move large items - our crew handles protective covering as part of standard setup. If you have specific concerns about original finishes, antique registers, or accessibility limitations, note them when scheduling so we can allocate appropriate time and tools. The technician will confirm any site-specific preparations when delivering the written price before work begins.
