Air Duct Cleaning Company in Longmont, CO
If a room in your Longmont house never gets warm, or the register whistles and rattles when the furnace kicks on, the problem is usually the ductwork itself, not the furnace. Air duct repair in Longmont means finding where the system lost its seal or its shape and fixing it rather than cleaning around it. This city is hard on ducts. A semi-arid high-plains climate throws wind-driven grit at every intake, spring cottonwood pollen packs the returns, and a big share of the housing stock has now been running builder-grade flex duct for two decades. We run contractor-grade equipment: Rotobrush brush agitation paired with Nikro HEPA extraction. Call (866) 361-9658.
Why Longmont Homes Are Different
Longmont sits where the plains meet the foothills, and the wind corridors along the west side carry grit off open farmland straight into intake plenums. That fine reddish-brown dust never really shows up in the tighter, newer subdivisions farther from ag land. Add heavy cottonwood pollen in spring and the dry, low-humidity air that comes with forced-air heating, and return systems here load up faster than in wetter Colorado towns.
The housing divides into two very different repair problems. The 1990s to 2000s tech-boom tract subdivisions were built with flex-duct runs and undersized filter grilles, and those materials are now more than twenty years old, sagging, kinked and separated at the collars. Closer to downtown and along the St. Vrain river corridor, the 1950s to 1970s ranch homes have galvanized trunk lines with taped joints that dry out and let air escape into crawlspaces and wall cavities. Neither problem responds to a vacuum alone. Permits vary by job scope, so confirm with the city before structural duct changes.

Our Main Longmont Services
Most Longmont homeowners reach us for one of two things: a full-system duct cleaning, or a dryer vent that has quietly clogged. Both are handled by the same trained technicians.
Air Duct Cleaning in Longmont
A full cleaning here means brush agitation through every branch run plus negative-pressure HEPA capture at the main trunk, so dislodged debris leaves the system instead of settling in the next room. On Longmont’s older ranch homes we pay close attention to the galvanized trunks, where decades of dry air have hardened the tape and left gaps that trap dust. On the 1990s subdivisions we work the flex runs carefully, since brush pressure has to be matched to the material. We can also supply and install Honeywell and Aprilaire filtration on the same visit.
For the full breakdown of the process, see air duct cleaning.
Dryer Vent Cleaning in Longmont
Longmont’s dry climate does not stop lint from building up, and the long vent runs common in two-story subdivisions give it plenty of room to collect. A clogged dryer vent makes the dryer work harder, lengthens dry times and raises fire risk. We run the full length of the vent, clear the termination hood and confirm airflow at the end. If the run is crushed behind the dryer or kinked at an elbow, we flag it the same visit.
Details on scheduling and what we check are on our dryer vent cleaning page.
Air Duct Repair in Longmont
Air duct repair in Longmont is mostly a story about two eras of construction and one very dry, windy climate. The 1990s to 2000s subdivisions were built fast with flex duct and small filter grilles, and those runs are now old enough to sag, separate and leak at the collars. Older ranch homes near downtown and along the St. Vrain corridor have galvanized trunks whose taped joints have dried out. Spring wind pushes fine grit and cottonwood fluff through every gap, and once that material is inside the system it keeps recirculating. Repairing the ducts is what stops the cycle. Our full Air Duct Repair work covers sealing, re-running and replacing sections of the system, and it is handled by the same technicians who clean it.
Ductwork Repair
Signs you need it
You notice whistling or a rattle at a register, a room that never warms, visible tape peeling off a joint in the basement, or dust settling on surfaces right after a cleaning.
What it costs in Longmont
Most ductwork repairs land in the typical range of $200 to $650, with the written estimate setting the final price once we see the run.
How we do it
We pressure-check the system, locate the separation or crushed section, then re-seal joints with mastic or replace the damaged span and confirm airflow at the registers.
Air Duct Replacement
Signs you need it
The flex duct has collapsed or torn through in several places, or a run is so kinked and patched that repair would cost nearly as much as replacing it.
What it costs in Longmont
Air duct replacement typically runs from $450 to $1,800 depending on how many runs are involved and how accessible the attic or crawlspace is, with the final price set by the written estimate.
How we do it
We disconnect the failed run, pull it out, install new duct sized to the register, seal every collar and joint, and check static pressure before we call it done.
What Air Duct Repair Costs in Longmont
| Item | Typical range in Longmont |
|---|---|
| Ductwork repair (sealing, reconnecting, patching) | $200 – $650 |
| Air duct replacement (per run) | $450 – $1,800 |
| Full-system air duct cleaning | $350 – $700 |
Can duct repair fix a room that never gets warm?
Often, yes. A cold room usually points to a disconnected run, a crushed flex duct or a leaking joint dumping air into an attic. We pressure-check the system to find it, and the written estimate sets the price before work starts. Call (866) 361-9658 for a free estimate.
Do you repair ducts you did not install?
We do. We work on builder-grade flex duct, galvanized trunks and everything between, whatever the original installer used. Our technicians have up to 10 years of experience with both materials, and we photograph the before and after so you can see what changed.
Brands We Service in Longmont
Our equipment roster centers on Rotobrush and Nikro for cleaning, Abatement Technologies for filtration when a job involves contamination, and Guardsman in the service mix. We also supply and install Honeywell and Aprilaire filtration products. We don’t stock parts locally, so turnaround depends on the job. See our brands.
