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 Boulder
Air duct cleaning in Boulder typically costs between $450 and $850 for a full residential system, depending on home size, duct condition, and whether wildfire smoke remediation is needed. Most jobs are completed in four to seven hours, and we schedule Boulder appointments Monday through Saturday. If you’ve been putting this off because you don’t want a stranger in your house, that’s the exact problem we built Linden Air Duct Cleaning to solve.
We’ve worked Boulder homes since the Marshall Fire sent smoke and ash through thousands of HVAC systems in the Boulder Valley in December 2021. We know this city’s ducts, its dust, and its housing stock better than any company driving up from Denver for the day. Call (980) 447-2498 and you’ll get a real person on the line, not a voicemail tree.
Why Linden Air Duct Cleaning Is Boulder’s Preferred Air Duct Cleaning Company
Boulder homeowners keep calling us back for one reason: we tell them exactly who is coming to the door before that person shows up. Every technician is background-checked and identity-verified under The Threshold Standard. You get the tech’s name and photo sent to you before the visit. When they arrive, they show a photo ID badge at the door. No unmarked vans, no mystery contractors.
Our crews work Boulder neighborhoods every week: Table Mesa, Martin Acres, Baseline, The Hill, Wonderland Hills, Gunbarrel, and up into the foothills subdivisions. We understand what 1960s tract construction means for duct systems, how Chinook winds load return-air pathways with fine grit, and why apartments near CU have dryer vent stacks that haven’t been properly cleared in a decade.
Marcus Veale, who leads our Boulder operations, grew up working on Colorado’s Front Range and has spent years diagnosing duct failures in aging ranch homes. He trained our Boulder crews to look for the problems other companies drive past: subfloor return-air gaps, poorly sealed plenums, and smoke residue that general-purpose cleaners never touch. When you book with Linden, you’re getting a crew that knows this city’s specific duct failure modes by heart.
Vent Cleaning in Boulder
Vent cleaning in Boulder homes is a different job than it is in Denver or Colorado Springs because of what Boulder’s wind patterns push into your supply registers. Chinook downslope windstorms routinely exceed 100 mph along the mountain-plains interface, and they carry exceptionally fine clay and loess dust stripped from the Front Range foothills. That dust settles into supply vents, coats register covers, and works its way back into the duct branches when your blower cycles. A surface wipe doesn’t touch it.
Our Air Duct Cleaning team runs what we call a full-vent source removal on Boulder jobs: we pull each register, use negative-pressure extraction through the supply side, and HEPA-filter the outlet air so we’re not just stirring dust around your living room. Typical vent cleaning as part of a full system job in Boulder adds $80 to $150, depending on the number of registers. A standalone vent cleaning for a single-story ranch runs $200 to $350.
Supply and return register detailing
Boulder’s semi-arid climate means register grilles collect a baked-on film that household cleaners won’t budge. We remove each cover, degrease it with a commercial coil cleaner, and hand-detail the fins before reinstalling. It’s the difference between clean air flowing through a dirty grille and actually clean supply air.
Chinook dust mitigation
After major wind events in March and November, we get a wave of calls from Boulder homeowners whose registers are blowing visible dust into the room. The fix isn’t just cleaning; it’s checking whether your return-air plenum is pulling in outside dust, which is the underlying problem in a surprising number of older Boulder homes.
Ductwork Cleaning in Boulder
Ductwork cleaning in Boulder starts with a question most companies never ask: how old is your home’s original return-air design? Boulder’s open space program and building height Blue Line have constrained new residential construction for decades, so a huge share of the housing stock is 1950s to 1970s ranch-style homes in Table Mesa, Martin Acres, and Baseline with original sheet-metal ductwork. Much of it has never been professionally serviced. Not once.
Our full-system ductwork cleaning uses Rotobrush and Nikro equipment with negative-pressure extraction, meaning we pull air backward through the ducts while loosening debris from the walls, trapping everything in a HEPA-filtered collection system. No blow-through shortcuts. No dirty air recirculating into your home. Full system cleaning for a typical Boulder ranch runs $500 to $850. Two-story homes and homes with crawlspace duct runs on the upper end of that range.
Return-air plenum inspection
This is where Boulder’s 1960s tract construction creates problems you won’t find in newer Denver suburbs. The original subfloor return-air plenums in South Boulder and Table Mesa frequently have gaps at the subfloor level, a framing shortcut from that era. Those gaps mean your system has been pulling crawlspace dust, radon-laden soil air, and post-Marshall-Fire smoke particulates directly into the ductwork instead of just recirculating indoor air.
Camera verification
After source removal, we run a video inspection camera through your main trunk and branch runs to confirm the walls are clear and the plenum is sealed. You see the footage. It’s not a sales trick; it’s how we verify the job was done.
Trusted Brands We Service in Boulder
We run Rotobrush and Nikro source-removal equipment, the same professional-grade machines used in hospital and commercial duct systems. For air-quality products, we work with Abatement Technologies for HEPA filtration and Guardsman for antimicrobial surface protection after cleaning. We stock common replacement components locally for Boulder jobs: register covers, plenum patches, and filter housings. That means when we find a return-air gap under your subfloor, we fix it the same day instead of ordering a part and coming back two weeks later.
Common Air Duct Cleaning Problems We See in Boulder Homes
- Subfloor return-air gaps in 1960s tract homes. The original framing around return-air plenums in Table Mesa and Martin Acres was often left with open gaps at the subfloor level. Your blower has been inhaling crawlspace air for 50 years. We seal those gaps as part of the job.
- Marshall Fire smoke residue that won’t clear on its own. Smoke particulates from the December 2021 fire settled inside thousands of Boulder Valley duct systems. Recirculating air keeps pushing that residue back into living spaces until someone does real source removal.
- Chinook-driven loess dust bonded to older sheet metal. Fine clay and loess dust from the foothills bonds harder to aging duct walls at Boulder’s 5,430-foot elevation. A quick blow-through won’t remove it; negative-pressure source removal will.
- Shared dryer vent stacks in dense CU-adjacent housing. Apartments and older duplexes on The Hill often share a single dryer vent stack through the building. Cleaning one unit’s lint path isn’t enough; the shared stack keeps pushing lint back, and that’s a fire risk we take seriously.

FAQs About Air Duct Cleaning in Boulder
Boulder sits at 5,430 feet in a semi-arid climate with Chinook wind events that drive fine foothills dust into return-air pathways more aggressively than in Denver, which sits lower and more shielded from the strongest downslope winds. Add wildfire smoke events like the Marshall Fire, and Boulder systems accumulate particulate loads faster. Most Boulder homes need duct cleaning every three to five years, versus four to six in Denver. Call (980) 447-2498 and we’ll help you figure out what your system actually needs.
Yes. Smoke particulates measured in microns penetrate HVAC systems through return-air intakes, especially when systems are run continuously during evacuations or fires. The Marshall Fire deposited smoke and ash into duct systems throughout the Boulder Valley, and for homes with subfloor return-air gaps, smoke was pulled directly from outside air into the ducts. A standard cleaning won’t address that smoke residue; source removal with HEPA filtration is what it takes. We can inspect and quote the work specifically for your system.
We coordinate with building managers and HOAs for access to mechanical rooms, rooftop units, and shared duct risers. For individual units, we clean the accessible duct runs and supply registers, then verify what’s shared versus unit-specific so you know what was cleaned and what the building is responsible for. We also flag shared dryer vent stacks that need building-level attention, because single-unit cleaning won’t clear a shared lint pathway.
Older sheet-metal ductwork from the 1950s and 1960s runs differently than modern flex duct. The metal is often thinner, joints are looser, and the original return-air plenums frequently have gaps at the subfloor where they were framed incorrectly. We clean those systems at lower negative pressure to avoid damaging aging runs, inspect plenum integrity with a camera, and seal gaps before we finish. In Table Mesa, our tech once traced a stubborn dust complaint to an original 1960s subfloor return-air plenum with open framing gaps; the air handler’s blower motor was caked with foothills loess and post-Marshall Fire ash. We sealed the plenum gaps, ran source removal with negative pressure and HEPA filtration on the supply and return ducts, then camera-inspected to confirm the run was clear.
Shared dryer vent stacks in CU-adjacent rentals around The Hill and along Baseline mean one tenant’s lint isn’t the only thing clogging the line. Lint accumulates from multiple units into a single stack, and that shared pathway raises fire risk for the entire building, not just one apartment. If you rent or own in dense Boulder housing, ask us to inspect the vent path. We’ll tell you honestly whether it’s clean or whether the building itself needs attention.
