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.

AfterCommercial Duct Cleaning in Denver, CO
Commercial duct cleaning in Denver typically runs between $800 and $4,500 depending on building square footage, duct configuration, and how long it has been since the last documented cleaning. Most mid-sized commercial jobs in Denver are completed in a single day, and every CleanRun job ends with a written photo record of every duct run – before and after – so building owners and facility managers have something concrete to show a health inspector, a tenant, or their own ownership group.
Commercial ductwork carries the same particulate load as residential duct systems, just at a much larger scale. In Denver’s climate, that means construction dust from the constant renovation cycle across the metro, pollen from the Front Range’s dry spring seasons, and debris accumulation inside plenum boxes – the central distribution chambers that feed air to multiple zones simultaneously – that can go unnoticed for years. If the last cleaning your building received was a $79 coupon job with a shop vac, what you got was noise. What CleanRun delivers is documented negative-pressure extraction using professional-grade equipment from Rotobrush and Nikro, with photographs of every duct run as a standard job deliverable, not an add-on.
Tomas Reyes founded CleanRun in 2013 and has since overseen documented cleanings in more than 52,000 properties across the Denver metro. Commercial work is handled under the same H.A.V.E.N. Standard that governs every job: written price before work starts, background-checked uniformed technicians identified by name before arrival, and a 365-Day Done Right Promise backed in writing.

When You Need Commercial Duct Cleaning
- Visible dust discharge at supply registers. If tenants are reporting a fine grey film on desks near air registers, particulate is moving through the duct system and being deposited at every diffuser. In older LoDo and Capitol Hill commercial buildings, this is often compounded by deteriorating duct liner that sheds fibrous debris into the airstream.
- Occupant complaints about air quality or odors. When multiple people in different zones report the same musty or stale smell, the duct system is the common denominator. The camera usually finds the cause: moisture intrusion at a flex duct connection, bio-film on a cooling coil, or debris that has compacted into a damp mass at a low elbow point.
- Post-construction or post-renovation cleanup. Denver’s construction market runs year-round, and drywall dust, joint compound particulate, and insulation fibers are pulled directly into return air grilles during any active renovation phase. If the system ran during the build-out, it needs cleaning before full occupancy.
- Routine compliance documentation for commercial tenants or property managers. Institutional tenants, medical offices, and food-adjacent businesses in Denver increasingly require written evidence of duct cleaning as part of lease compliance. The Documented Photo Record CleanRun provides meets that requirement; a verbal assurance from a previous contractor does not.
- HVAC efficiency loss and rising utility costs. When duct walls carry a significant debris load, static pressure increases across the system – meaning the air handler works harder to move the same volume of air. Facility managers in Denver’s Cherry Creek and Stapleton commercial corridors have reported measurable reductions in utility costs after documented duct cleaning restored design airflow.
- More than three to five years since the last verified cleaning. If you cannot produce documentation – a written scope, an invoice, or a photo record – from a prior cleaning, it is reasonable to treat the system as uncleaned. The NADCA standard recommends cleaning commercial systems every three to five years under normal occupancy; high-traffic spaces warrant more frequent service.
Our Commercial Duct Cleaning Process
- Pre-job inspection and written scope delivery. Before any equipment comes off the truck, a CleanRun technician walks the system with a camera – starting at the air handling unit, through the plenum, and to each supply and return branch. What the camera shows gets documented. A written price is then delivered based on actual system configuration, not a per-vent formula that ignores duct diameter and run length. Haven Standard Clause 1: no work starts without a written price in your hand.
- System isolation and negative-pressure setup. Negative-pressure extraction means the duct system is placed under controlled suction using professional-grade collection equipment from Nikro – a HEPA-rated industrial vacuum unit that maintains the system under negative pressure throughout the cleaning. This prevents dislodged debris from being pushed back into occupied spaces. Supply and return sides are worked separately to maintain directional control.
- Mechanical agitation of all duct runs. Rotobrush rotary brush systems are used to mechanically break the bond between built-up debris and duct walls before extraction. The brush diameter is matched to the duct size – a 6-inch brush in a 6-inch round run, for example – to ensure full contact without damaging the duct liner. Every branch from the main plenum is agitated and extracted individually; no runs are skipped.
- Register and grille cleaning. Every supply register and return air grille is removed, inspected, and cleaned before being reinstalled. In commercial settings, diffusers often carry a separate debris load from the duct run itself due to turbulent airflow patterns at the outlet. This step is included in the standard commercial scope – it is not a line-item add-on.
- Post-cleaning camera documentation. Every duct run is photographed after cleaning with the same camera used during the pre-job walkthrough. The before-and-after photo record is organized by zone or branch and delivered to the building owner or facility manager as part of the standard job package. This is the deliverable that distinguishes documented work from vacuum noise.
- Final system check and written job record delivery. The air handling unit is returned to normal operation, static pressure is observed, and the technician walks the building with the customer before leaving. The written job record – including scope, pricing, technician identification, and the full photo documentation – is delivered on the day of service. The 365-Day Done Right Promise then covers the work from that date forward.
BeforeAfterCommercial Duct Cleaning Pricing in Denver
Commercial duct cleaning in Denver is priced on system size and configuration, not on a flat per-vent rate. A per-vent price sounds simple but routinely misrepresents the actual scope because it ignores duct diameter, run length, number of plenums, access constraints, and whether the system includes flex duct, hard metal, or a combination. CleanRun prices commercial jobs on a written scope delivered after a pre-job inspection – every time, no exceptions, per Haven Standard Clause 1.
The ranges below reflect actual completed jobs in the Denver commercial market. Use them to benchmark a competitor quote or to plan a maintenance budget.
| Building Size / System Type | Typical Denver Price Range | Notes |
|---|---|---|
| Small commercial suite (under 2,000 sq ft, single-zone) | $800 – $1,400 | Common in older Capitol Hill and LoHi commercial buildings; single air handler, limited branch runs |
| Mid-size office or retail (2,000 – 6,000 sq ft, multi-zone) | $1,400 – $2,800 | Multiple plenums, rooftop units common in Denver’s Cherry Creek corridor; access complexity often a factor |
| Large commercial floor or multi-tenant (6,000 – 15,000 sq ft) | $2,800 – $4,500 | Multiple air handlers, complex return-air configurations; day-of-service photo documentation included |
| Post-construction deep clean (any size) | Add $300 – $800 to base range | Drywall dust and construction particulate require additional agitation passes; common in Denver’s RiNo and Sunnyside development zones |
| Sanitizing treatment (optional add-on) | $150 – $400 depending on system size | Applied after mechanical cleaning; appropriate for systems with confirmed bio-film or odor-producing organic accumulation |
What moves a job toward the higher end of any range: restricted attic or ceiling return duct cleaning access that requires additional setup time, systems that have not had documented cleaning in more than five years and carry a heavy debris load, rooftop unit configurations common across Denver’s mid-century commercial stock, and buildings with asbestos-wrapped ductwork that requires abatement-protocol handling before standard cleaning can proceed.

FAQs – Commercial Duct Cleaning Denver
How long does commercial duct cleaning take in Denver?
Most commercial jobs in Denver between 2,000 and 8,000 square feet are completed in four to eight hours during a single visit. The pre-job camera inspection typically takes 30 to 60 minutes depending on system complexity, and that time is included in the job – it is not billed separately. Larger multi-floor systems or buildings with multiple rooftop units may require two days; that will be stated in the written scope before work begins. Call (720) 799-2292 to get a timeline estimate specific to your building’s configuration.
Does commercial duct cleaning cause disruption to tenants or business operations?
Air duct cleaning using negative-pressure extraction contains dislodged debris inside the duct system, so dust release into occupied spaces is minimal when the process is followed correctly. CleanRun can schedule commercial work during off-hours or weekends for tenant-occupied Denver buildings where daytime disruption is not acceptable – and that scheduling preference is noted in the written scope at no additional cost. The air handling unit is taken offline only for the portion of the job that requires it; zone-by-zone sequencing allows partial building occupancy in most cases.
What documentation does CleanRun provide after a commercial cleaning?
Every commercial job receives a full Documented Photo Record: camera images of every duct run before and after cleaning, organized by zone or air handler and delivered to the building owner or facility manager the day of service. The package also includes the written scope, the written price, technician identification (name and background-check status per Haven Standard Clause 3), and the 365-Day Done Right Promise in writing. This documentation is what institutional tenants and property managers in Denver need for compliance files; it is included as a standard deliverable, not an upgrade.
How often should a Denver commercial building have its ducts cleaned?
NADCA recommends commercial duct cleaning every three to five years under normal occupancy conditions. Denver-specific factors push that toward the shorter end: the city’s high-altitude dry climate accelerates dust accumulation in ductwork, construction activity across the metro regularly introduces heavy particulate loads into running systems, and any building that went through renovation or tenant build-out during the cleaning interval should be treated as due regardless of calendar date. If you cannot produce a documented record from the last cleaning – a written scope or a photo record – the reasonable starting point is to treat the system as uncleaned and schedule an inspection. Call (720) 799-2292 to arrange a camera inspection before committing to a full cleaning.
Why Denver Commercial Properties Work with CleanRun
The commercial duct cleaning market in Denver runs on the same coupons and vague assurances that drive full system cleaning on the residential side, just at a larger price tag. A building owner in the Highlands or a facility manager in Englewood who signs off on a $1,200 cleaning with no written scope and no documentation has no way to know whether the system was cleaned or the crew spent three hours making noise near the air handler. That is not a hypothetical – it is the feedback CleanRun hears from building owners who call after a prior contractor’s work fails a basic camera inspection.
CleanRun’s position is straightforward. The work either holds up to a camera or it does not. The 365-Day Done Right Promise means if it does not hold up – if the photo record shows a run that was not fully cleared, or a register that was missed – CleanRun returns and corrects it at no additional cost. That promise is written on the job record, not stated verbally and then subject to interpretation later.
Tomas Reyes built the H.A.V.E.N. Standard around one premise: a customer who can see the evidence does not need to trust the marketing. The Documented Photo Record is the evidence. The written price before work starts is the standard. The 365-Day Done Right Promise is the accountability. For commercial properties in Denver, those three things together are what a cleaning record actually looks like – and what a health inspector, an institutional tenant, or a property ownership group can actually use.
CleanRun serves commercial properties throughout Denver and the surrounding metro, including properties in Capitol Hill, LoDo, Cherry Creek, RiNo, the Highlands, Sunnyside, and Stapleton. If your building is in a neighborhood not listed here, call (720) 799-2292 – all calls are answered by a live person, and a written commercial estimate can typically be scheduled within 48 hours of the initial call.
