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 runs $350 – $650 for a full residential system and is usually scheduled within a few business days, with dispatch coordinated from our Denver office and crews serving Boulder directly. If you’re noticing more dust settling on your North Boulder countertops, or your family is sneezing through juniper pollen season despite windows staying shut, the problem is likely circulating through your ductwork.
We’ve been cleaning ducts across the Front Range since 2004, and Boulder presents a specific set of challenges you won’t find in every Colorado market. The combination of wildfire smoke from the surrounding foothills, intense spring pollen loads, and the city’s widespread use of swamp coolers means your system is working harder than comparable homes in less exposed areas. Our crews know the difference between standard forced-air ductwork and the separate cooler ducts common in Table Mesa and South Boulder neighborhoods. When you call (361) 326-5060, you’ll reach a live person who can schedule your free estimate and explain what your particular setup needs.

Air Duct Inspection in Boulder
Air Duct Inspection in Boulder starts with understanding whether your home has one duct system or two. Many Boulder residences, especially in older neighborhoods like Table Mesa and parts of South Boulder, still run swamp coolers through separate ductwork from their winter furnace systems. Our inspection identifies which ducts serve which function, checks for mold in cooler lines, and maps debris accumulation from local pollen and wildfire ash.
A typical inspection in Boulder runs $150 – $250. We use video inspection equipment to show you what we’re seeing inside your galvanized or flexible ductwork, whether it’s original 1960s material or newer construction from North Boulder developments.
When to Schedule
Book an inspection if you’ve noticed uneven airflow, musty smells when the cooler starts up, or visible dust puffing from registers after windstorms off the Flatirons. These are early indicators that your system is circulating more than just temperature-controlled air.
What the Report Includes
You’ll receive a written assessment with photo documentation, a clear diagram of your duct layout, and a flat-price quote for any recommended cleaning. No open-ended estimates, no pressure to commit on the spot.
Residential Air Duct Cleaning in Boulder
Residential Air Duct Cleaning in Boulder addresses the specific contamination patterns this city’s climate produces. Our rotary brush systems from Rotobrush and negative-air machines from Nikro dislodge and extract fine ash particles from wildfire smoke, compacted juniper pollen, and the mineral deposits that swamp coolers leave behind in duct walls.
A full residential cleaning in Boulder typically costs $350 – $650 depending on system size, accessibility, and whether we’re servicing one duct network or two. Homes in older neighborhoods with original galvanized ductwork often require more time, as seams deteriorate and trap debris newer systems would shed.
Swamp Cooler Duct Considerations
Cooler ducts in Boulder run constantly through dry summers and accumulate moisture that supports mold growth. We treat these lines with specific protocols, checking the pads, reservoir, and blower assembly as part of a complete job.
Post-Cleaning Verification
After cleaning, we run a second video pass so you can see the difference. Before-and-after footage is yours to keep, along with written documentation of the work for your records.
Trusted Brands We Service in Boulder
Our equipment roster includes professional-grade rotary brush systems from Rotobrush, negative-air extraction units from Nikro, and filtration products from Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use on larger Boulder County jobs, not hardware-store attachments. We stock common replacement parts locally, so if our inspection turns up a damaged register boot or deteriorating flex connection in your Gunbarrel home, we can often address it during the same visit rather than rescheduling. For specialized components or older system configurations common in Boulder’s 1950s – 1970s housing stock, we source quickly through our Denver coordination office and return promptly.
Common Air Duct Cleaning Problems We See in Boulder Homes
- Wildfire ash accumulation in return ducts. Smoke from Front Range fires introduces fine particulate that standard furnace filters don’t catch. Over seasons, this ash compiles in return lines and recirculates whenever the blower cycles.
- Mold in swamp cooler supply lines. The moisture evaporative coolers add to airflow creates ideal conditions for mold growth in duct walls, especially in the dry climate where systems run continuously from May through September.
- Collapsed flexible ductwork in older homes. Many Boulder neighborhoods built between 1950 and 1970 used early flexible duct products that have degraded, sagging or separating at seams and creating both blockages and contamination points.
- Pollen loading from juniper and foothills vegetation. Boulder’s spring pollen counts rank among Colorado’s highest, and particles small enough to pass through standard filters settle in ductwork, aggravating allergies even indoors.

FAQs About Air Duct Cleaning in Boulder
Most Boulder appointments are scheduled within 3 – 5 business days, with dispatch coordinated from our Denver office and crews traveling directly to your address. Peak pollen seasons and post-wildfire periods may extend this slightly. Call (361) 326-5060 to check current availability.
We work across all Boulder neighborhoods including North Boulder, Table Mesa, South Boulder, and Gunbarrel, plus the hillside homes near Chautauqua and the canyon-adjacent properties west of Broadway. Our crews are familiar with the access challenges and duct configurations specific to each area.
We don’t classify duct cleaning as an emergency service, but our phones are answered by a live person 24/7. If you’re experiencing severe airflow issues, visible mold, or post-fire contamination that affects breathing, we’ll prioritize your scheduling and often accommodate next-day service when capacity allows.
Boulder pricing runs roughly comparable to Denver, sometimes 10 – 15% higher for homes with dual swamp cooler systems or difficult hillside access. The specific contamination challenges, wildfire ash and heavy pollen loads, can also mean more intensive cleaning cycles in some cases.
Every job is backed by our 365-Day Done Right Promise in writing. If the cleaning fails, if mold returns in treated cooler ducts, or if workmanship issues appear within a year, we return and make it right at no charge. This includes a free second visit, not a partial credit or negotiation.
