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 Denver
Air duct cleaning in Denver typically costs between $380 and $680 for a full system on a standard 3-bedroom home, and the work usually takes 4 to 6 hours from setup to final photo documentation. We serve every Denver neighborhood, from Harvey Park to Montbello to Central Park, with crews that know exactly what 50-to-70-year-old ductwork looks like when it’s never been touched. If you’re noticing dust on every surface within days of cleaning, a musty smell when the furnace kicks on, or rooms that never quite reach temperature, call (806) 606-6902 and we’ll give you a written price before any work begins.
Why CleanRun Air Duct Cleaning Is Denver’s Preferred Air Duct Cleaning Company
Denver homeowners call us because we show them what’s inside their ducts before we ask them to believe a word we say. Every visit includes a camera inspection of the plenum, trunk lines, and branch runs. You see the debris. You see the disconnect. You see the before photo, and when we leave, you see the after photo. That’s the whole pitch. No one in Denver should pay for duct cleaning without seeing the inside of their own system first.
Our Air Duct Cleaning team works under the H.A.V.E.N. Standard, which means background-checked, uniformed technicians who arrive identified by name. Tomas Reyes leads our crews and has built the company’s reputation on one principle since 2013: a written price before a single panel comes off, and a Documented Photo Record of every duct run delivered as part of the standard job record. You don’t have to trust us. You just have to look at the photos.
We’re not the company that quotes $79 over the phone and then finds $900 worth of “problems” once the van is parked in your drive. We price by the system, in writing, before work starts, under Haven Standard Clause 1. Denver homeowners who’ve been burned by bait-and-switch duct cleaners tell us that single practice is why they called us instead of the next coupon in the mailer.
Our Air Duct Cleaning Services in Denver

Residential Duct Cleaning
Most Denver homes we clean are ranches and split-levels built between 1950 and 1975, and they share a common profile: original galvanized sheet-metal ductwork, decades of accumulated dust, and at least one disconnected run somewhere in the system. We clean the full length of every run, from return boot to supply register, using negative-pressure extraction with HEPA filtration so debris is pulled out, not blown into your living room. After the clean, you get photos of every run. If we find crushed or separated ductwork, we tell you what it costs to fix before we touch it.

Commercial Duct Cleaning
Denver’s office buildings, clinics, and retail spaces along corridors like Colorado Boulevard and Federal Boulevard accumulate a different kind of buildup: higher foot traffic means more skin cells, carpet fibers, and paper dust cycling through the HVAC. We schedule commercial work around your operating hours and provide the same written pricing and photo documentation we give residential customers. No vague line items. No surprises at invoice time.

Supply Duct Cleaning
Supply ducts are the runs that carry conditioned air from your furnace out to each room. In Denver’s dry climate, fine mineral dust loads these runs quickly because there’s no humidity to settle it out of the air stream. We camera every supply run before cleaning to check for collapsed sheet metal or cracked flex duct in newer homes. Then we clean the full length of the run, not just the first few feet from the register. The camera goes back in after the clean, and you see the difference.

Return Duct Cleaning
Return ducts are the forgotten half of most Denver duct systems. They pull air back to the furnace, and in older ranches in neighborhoods like Barnum and Westwood, that return path often runs through unfinished basements where it’s collected dust, pet hair, and in some cases, wildfire ash from the 2021 Marshall Fire. Return plenums are where we find the worst buildup, because nothing filters the air before it reaches the furnace. A clean supply side means little if the return side is still caked. We clean both, and we photograph both.

Full System Cleaning with Video Inspection
Our video inspection is the difference between paying for work and proving work was done. We run a camera through the main trunk, every branch, and the boots at each register. You see what we see, in real time or in the photo record afterward. For Denver’s older homes, this inspection often reveals problems that have nothing to do with dirt: separated boots, crushed runs, gaps behind drywall. The cleaning fixes the dirt. The inspection finds the air leaks that are stealing airflow from your bedrooms.

AfterTrusted Brands We Service in Denver
We work on systems from every major manufacturer, and we stock replacement parts locally for Denver’s most common configurations, including Honeywell and Aprilaire filtration components. For sealing and encapsulant work on smoke-exposed duct liners, we use Guardsman encapsulant products and Abatement Technologies HEPA filtration equipment. If your system has a specific brand or configuration, ask us when you call; if we need to order a part, we’ll tell you the timeline before you commit to anything.
Common Air Duct Cleaning Problems We See in Denver Homes

- Decades-old galvanized ductwork in 1950s-1970s ranches. Homes in Harvey Park, Barnum, and Montbello almost universally have original sheet-metal ducts that have never been professionally cleaned. The metal itself is often sound, but the interior is loaded with 50-plus years of compacted dust, coal-era residue, and wildfire particulate.
- Crushed or disconnected runs in unfinished basements. Original ductwork in older Denver basements often pulls apart at the boots or collapses under slab settling. Air being cleaned never reaches the bedrooms, and homeowners blame the furnace when the real issue is a gap behind drywall.
- Wildfire smoke residue in flex duct liners. After the Marshall Fire and subsequent Front Range smoke events, homes across Denver absorbed smoke oils into return plenums and flex-duct liners. Vacuuming alone won’t remove it. Without encapsulant treatment, the campfire smell returns with the first heating cycle in October.
- Extreme dryness accelerating particulate loading. Denver averages about 14 inches of precipitation per year, which means dust stays airborne far longer than in humid markets. Rapid temperature swings, 40-to-70°F shifts within a single day are routine, cause HVAC systems to cycle constantly, pulling more airborne dust into the ducts with every cycle.
Pricing for Air Duct Cleaning in Denver, CO
A full residential system cleaning in Denver runs $380 to $680 for most homes up to 3,000 square feet. Larger homes with multiple systems or extensive flex-duct runs can run $700 to $950. Commercial pricing is quoted per system based on square footage and duct configuration. Here’s what affects your number:
- Number of systems. A single-furnace ranch costs less than a two-furnace two-story.
- Access difficulty. Finished basements with enclosed ductwork take longer than open unfinished basements.
- Condition of existing runs. If we find crushed or disconnected ductwork that needs sealing or re-supporting, that’s additional work we quote separately, in writing, before touching it.
- Smoke or odor treatment. Post-wildfire encapsulant work adds $150 to $300 depending on the number of affected runs.
The price we quote is the price you pay. One flat price per system, agreed before work starts. No per-vent pricing, no add-on surprises. Call (806) 606-6902 for a written estimate.

FAQs - Air Duct Cleaning in Denver

The honest answer is you won’t know until someone puts a camera inside the ducts. If the sheet metal is intact and connected, a full source-removal cleaning is all you need. But if the camera shows separated boots, gaps at the plenum, or crushed runs where sheet metal collapsed under settling slab, sealing and re-supporting are the real fix. We include the video inspection with every job precisely so you can see which situation you’re in. Call (806) 606-6902 and we’ll find out together.
Because vacuuming removes particulate, not smoke oils. After the 2021 Marshall Fire, smoke oils permeated flex-duct liners and return plenums across Denver. Those oils cling to the duct interior and release odor when heated. A standard cleaning pulls out the ash and soot, but the liners need encapsulant treatment to seal the oils in place. If you had a cleaning after the fire and the smell returned with heating season, that’s almost certainly what happened. Call (806) 606-6902 and we’ll explain the encapsulant process and what it costs.
Dry air reduces mold risk, yes, but it does the opposite for dust accumulation. Denver’s average 14 inches of annual precipitation means fine mineral dust stays airborne far longer than in humid markets. It settles into ducts, compacts over time, and resists normal airflow from dislodging it. Most Denver homes we clean have zero mold, but significant particulate buildup. The dry air doesn’t make cleaning unnecessary. It makes the problem different. And it’s still worth cleaning.
Flex duct is more fragile than sheet metal. Denver’s extreme dryness and daily temperature swings cause the plastic liner to become brittle, and we regularly find cracked flex runs in newer construction that’s only 10 or 15 years old. Cleaning flex duct requires lower air pressure and different tools than rigid metal. We also camera every flex run before cleaning because cracks can widen under cleaning pressure if we’re not careful. The process works. It just requires treating the material for what it is, not what it looks like from the register.
In most cases, yes. We access the ductwork through the existing registers, the furnace plenum, and any accessible basement runs. We don’t cut into ceilings or walls. If a specific run is crushed or separated behind finished drywall, we’ll show you the camera footage and explain your options. Sometimes the fix is simple; sometimes it requires opening a small access point. But you’ll know exactly what’s needed and what it costs before we do anything beyond the cleaning itself.
