Air Duct Cleaning Company in Longmont, CO
Air duct repair in Longmont is where most homes here actually start, because the failures are structural before they are about dirt. Longmont sits right on the Front Range wind corridor east of the foothills, and that steady push of fine prairie dust finds every gap in a return trunk. Add a housing stock that runs from mid-century brick ranches near downtown to long flex runs buried in chases in the newer eastern subdivisions, and you get ducts that leak as much as they collect. We handle repair, cleaning and dryer vents with professional-grade equipment. Call (833) 467-7154 for a free estimate.
Why Longmont Homes Are Different
Most duct work we look at in Longmont is shaped by two things: when the house was built and which side of town it faces. The small brick and cinder-block ranches around old town, mostly in 80501, often still have undersized original sheet-metal trunks with flex lines spliced in later, and those splices are where leaks begin. East toward 80504, the 1990s-2010s two-story subdivisions tend to bury long flex runs in unconditioned chases, and those runs collect debris because nothing sweeps them out. Rural-edge homes in 80503 add their own problem: foothills-driven downslope wind events leave a visible fine grit film on the return grilles of west-facing rooms. That pattern rarely shows up on the sheltered side of town. The dry, windy, high-altitude climate runs furnaces hard from November through March, and the low humidity keeps debris light and airborne rather than caked, so a spring or fall cleaning pulls out more loose material than the same job would in a wetter place. It’s a dust-plus-dry-air combination more pronounced here than in sheltered Boulder or in Denver’s wetter neighborhoods.

Our Main Longmont Services
Two jobs come up again and again when Longmont homeowners call us, and they’re the two below.
Air Duct Cleaning in Longmont
Cleaning a Longmont system means more than running a vacuum down a trunk. We agitate the duct walls with a Rotobrush rotary brush, then pull the loosened debris out with Nikro HEPA-rated equipment, and we run Abatement Technologies air filtration for the whole job so what we dislodge stays contained instead of drifting through your rooms. In the older ranches near downtown, that agitation matters most on the return side, where grit settles into every seam. In the newer eastern builds, it matters on the long flex runs. Our technicians have up to 12 years of experience, and we quote one flat price per system before anything starts. Details are on our air duct cleaning page.
Dryer Vent Cleaning in Longmont
A dryer vent packed with lint is a fire risk sitting behind an appliance, and it’s one of the most overlooked maintenance items in a Longmont home. Dryer runs here often travel a long way through unconditioned space before they reach an outside wall, which gives lint more surface to cling to and slows airflow. We clear the full run and confirm the exhaust is actually moving, rather than just poking a brush into the first few feet. Our professional-grade equipment handles the whole line. See what the visit covers on our dryer vent cleaning page.
Air Duct Repair in Longmont
Air duct repair in Longmont comes down to how the house was built and what the wind does to it. The old sheet-metal trunks under downtown ranches develop seam gaps and disconnected joints, while the long flex runs in 1990s-2010s subdivisions east toward 80504 sag, tear, or pull loose from their collars. Either way, a leaky return pulls prairie dust in from a crawlspace or attic instead of from the rooms it’s meant to serve. Repair is the same team and the same visit as the cleaning. Our technicians have up to 12 years of experience, and it’s all handled by the same trained crew, not referred out. Learn how our Air Duct Repair work is handled when we find a problem mid-job.
Ductwork Repair
Signs you need it
You notice grit on return grilles, rooms that never seem to get their share of heat, or a whistling at a joint when the furnace kicks on.
What it costs in Longmont
Ductwork repair typically runs $150 to $450 in Longmont, depending on how much has to be sealed or reconnected, with the written estimate setting the final price.
How we do it
We seal gaps and reconnect loose sections with mastic and proper mechanical fasteners, then confirm airflow at the registers so the fix actually holds.
Duct Replacement
Signs you need it
Sagging or crushed flex runs, ductwork that’s torn or contaminated beyond cleaning, or an old undersized trunk that can’t keep up with the system.
What it costs in Longmont
Duct replacement typically falls between $1,200 and $4,500 for a Longmont home, depending on run length and access, and the written estimate sets the final price.
How we do it
We measure the system, remove the failed sections, and install properly sized replacement runs with sealed connections, then check the whole system’s airflow before we leave.
What Air Duct Repair Costs in Longmont
| Item | Typical range in Longmont |
|---|---|
| Ductwork repair (sealing, reconnecting) | $150 – $450 |
| Duct replacement (per-home range) | $1,200 – $4,500 |
| Air duct cleaning (whole system) | $350 – $750 |
Price in Longmont rises with access difficulty, the number of disconnected or crushed runs we find, and whether the work is in a tight crawlspace or a buried chase. We agree one flat price per system before any work starts, and the written estimate is what you pay.
Can you repair ductwork the same day you clean it?
Yes. If we find a disconnected joint or a crushed flex run during the cleaning, the same trained team handles the repair on that same visit rather than scheduling a return trip. We confirm the scope and the price with you first.
Why does my west-facing room collect so much grit in Longmont?
Downslope wind events coming off the foothills hit west-facing rooms hardest, and fine prairie dust pushes through any gap in a return or supply joint. Sealing those leaks usually solves it.
Brands We Service in Longmont
We work with and around the filtration and air-quality brands a lot of Longmont homes already have, including Honeywell and Aprilaire filtration equipment, and we handle systems compatible with Guardsman and other common components. We don’t claim stocked parts, and if a brand-specific part is needed, turnaround depends on supply. You’ll find the wider list on our brands page.

What Longmont Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Travis Ziegler"Something came loose about a month after the work. Called them, and they were back out the next day and fixed it at no charge. Didn't argue, didn't try to bill me for the trip."
- Laura Meyer"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
