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.
Air Duct Cleaning Company in Boulder, CO
Linden Air Duct Cleaning is the air duct company for Boulder homeowners who want to know exactly who’s coming to the door, exactly what the job costs, and exactly what happens if anything falls short. Boulder ductwork faces a dual threat you won’t find the same way even 30 miles south in Denver: Chinook downslope windstorms driving fine grit into return-air pathways, and recurring wildfire smoke infiltration that has become a seasonal reality since the December 2021 Marshall Fire burned through Superior and Louisville. Add in a housing stock dominated by 1950s – 1970s ranch homes with original sheet-metal ductwork, and Boulder jobs demand a level of care most duct companies never plan for. Call us at (980) 447-2498 for a written estimate before any work begins.
Why Boulder Homes Are Different
Boulder sits at 5,430 feet in a semi-arid climate, and that elevation changes how ductwork behaves. Forced-air heating runs much of the year in very low humidity, which means fine particulate matter bonds faster and more stubbornly to duct interiors than it does at lower, more humid elevations. The Chinook winds that regularly exceed 100 mph strip exceptionally fine clay and loess dust off the Front Range foothills and drive it into return-air pathways. Then there’s the smoke factor. The mountain-valley wind pattern causes wildfire smoke to pool and linger in the Boulder Valley, increasing the volume of smoke particulates that infiltrate duct systems during fire season. After the Marshall Fire, we saw HVAC systems throughout the Boulder Valley coated in ash, and that remediation demand has become a recurring seasonal expectation here in a way it simply hasn’t in Fort Collins or Colorado Springs.
Boulder’s housing stock compounds the problem. The city’s open space acquisition program and building height Blue Line have constrained new residential development for decades, so a disproportionate share of homes are 1950s – 1970s ranch-style properties in Table Mesa, Martin Acres, and Baseline, many with original sheet-metal ductwork that has never been professionally serviced. Around The Hill, the dense concentration of aging CU-adjacent rental properties means high tenant turnover, and those duct systems routinely go 20 – 40 years between cleanings. Technicians working older South Boulder homes regularly find that original 1960s-era return-air plenums were built with gaps at the subfloor level, pulling decades of crawlspace dust, radon-laden soil air, and post-Marshall-Fire smoke particulates directly into the duct system rather than just recirculating indoor air. That’s a Boulder-specific condition we check for on every older home we service.
Our Main Boulder Services
Boulder homeowners call us most often for two things: cleaning duct systems that have accumulated decades of dust and smoke particulates, and repairing the aging ductwork that came with their ranch homes. Here’s what each job involves in Boulder specifically.
Air Duct Cleaning in Boulder
Our Air Duct Cleaning in Boulder service uses negative-pressure extraction, which means we pull air backward through the duct system under vacuum while agitating the interior walls to release bonded particulate. In Boulder, that particulate is often a stubborn mix of Chinook-driven clay dust and wildfire smoke residue, so we run longer agitation passes on older systems than we would in more humid Front Range cities. We cover supply and return ductwork, the main trunk line, and the return-air plenum, and we photograph the interior before and after so you can see the work was actually done. No per-vent pricing, no bait-and-switch; the price is written down before we start.

Dryer Vent Cleaning in Boulder
Boulder’s dry climate pulls a lot of moisture out of laundry loads, but lint traps don’t catch everything, and the fine particulate from the same Chinook dust that fills your ductwork also accumulates in dryer exhaust runs. We offer Dryer Vent Cleaning in Boulder that clears the full run from the dryer connection to the exterior termination, using rotary brushes and compressed air to break through packed lint. In many Boulder ranch homes, dryer vents run long horizontal distances through crawlspaces, which creates more friction and more lint buildup than short vertical runs on newer builds. A blocked dryer vent isn’t an inconvenience; it’s a fire hazard, and we treat it that way on every job.

Air Duct Repair in Boulder
When your Boulder home’s ductwork has the original 1960s plenum gaps we described, or seams that have separated after decades of thermal cycling, cleaning alone won’t fix the problem. Our Air Duct Repair in Boulder service seals, reconnects, and where necessary replaces damaged sections of ductwork, including subfloor return-air plenums that are pulling crawlspace air into the conditioned space. Every repair comes with a written guarantee and a free second visit if the repair does not hold. We inspect the full accessible duct run, show you photos of what we found, and give you a written price for the repair before any work begins.

Pricing for Air Duct Cleaning Company in Boulder, CO
| Service | Typical range in Boulder |
|---|---|
| Single furnace / air handler duct system cleaning | $300 – $500 |
| Each additional furnace / air handler system | $200 – $300 |
| Dryer vent cleaning (one vent, standard run) | $75 – $150 |

What pushes a Boulder quote toward the higher end of these ranges is usually the age and condition of the ductwork itself: original 1960s sheet-metal systems with plenum gaps or separated seams take longer to clean properly and may need repair alongside the cleaning. Whatever the number, the price is put in writing before we start, and that figure does not change unless you approve additional work in writing first.

FAQs About Air Duct Cleaning Company in Boulder
Most Boulder appointments are scheduled within a week, and we work around your availability once we confirm the job. We don’t promise same-day service because we believe in doing the work carefully, not fast. Call (980) 447-2498 and a live person will schedule a time that actually works for you.
