AfterHow Much Does HVAC Cleaning Cost in Boulder?
HVAC cleaning in Boulder typically runs $350 to $650 for a standard single-system home, with most households landing near $475 once the main trunk line, supply registers, and return drops are cleaned. Larger homes with two systems, finished basements, or heavy renovation dust often reach $700 to $1,100. Dryer vent cleaning is priced separately at $120 to $195, and duct repair is quoted after an inspection because it depends on what’s actually damaged.
These are typical estimate ranges for the Boulder market in 2026, not a fixed rate card. Every job gets a written estimate before any work begins, and that written estimate is what sets the final price. If you’re comparing bids and one is dramatically lower than the rest, ask what equipment they’re bringing and whether repair is part of the scope. A clean-only visit that leaves crushed flex duct and disconnected joints behind isn’t a bargain.
HVAC Cleaning Cost Breakdown (2026)
Here’s how the pieces usually add up for a Boulder home:
| Service | Typical Range |
|---|---|
| Air duct cleaning, single HVAC system (up to ~15 vents) | $350 – $550 |
| Air duct cleaning, larger home or second system | $550 – $850 |
| Heavy renovation or construction dust cleanup | $650 – $1,100 |
| Dryer vent cleaning (standalone) | $120 – $195 |
| Dryer vent cleaning, long or complex run | $195 – $325 |
| Air duct repair (reconnect, seal, replace flex run) | $200 – $700 |
| Whole-home filtration system service (Honeywell / Aprilaire) | $150 – $400 |
What pushes a job toward the top of a range? Mostly access and volume. A Boulder bungalow with a short, straight trunk line comes apart fast. A 1970s split-level with a finished basement, a second system in the attic, and flex duct that snakes around three corners takes longer and uses more of the machine’s reach. Renovation dust is its own category: fine drywall particulate settles everywhere and needs the higher-volume negative-air setup that Abatement Technologies equipment is built for. Duct repair adds cost only when we actually find something broken, and we show you what we found before quoting the fix.
What Affects HVAC Cleaning Pricing in Boulder
- Number of systems and vents. A single furnace-and-coil setup with a dozen registers is the baseline. Add a second system for a basement or addition and the price moves up accordingly. Two-system homes here often sit closer to $700.
- Duct material and layout. Rigid sheet-metal trunk lines are straightforward to contact-clean. Long runs of flexible duct, especially older flex that’s sagging or kinked, take more time and sometimes turn into a repair conversation.
- Contamination level. Routine household dust is one thing. Mold spores, rodent debris, or post-renovation particulate calls for negative-air containment and HEPA filtration, and that’s a longer, more careful job.
- Access. Crawlspaces, low attic clearances, and registers buried behind built-ins all slow a crew down. Boulder’s older housing stock in neighborhoods like Mapleton Hill and Whittier has plenty of tight, finished spaces that fall into this bucket.
- Dryer vent length and routing. A short rear-vent run is quick. A vent that travels up through the wall and out the roof takes longer to clean properly, and it’s the one we never skip because of what lint buildup can do.
- Filtration system type. If your home runs a Honeywell or Aprilaire whole-home filter, servicing it alongside the ductwork is a separate line item from a standard register-and-trunk cleaning.
One Boulder-specific factor worth mentioning: this is a dry, windy climate with a long heating season and plenty of spring pollen. Homes here pull in a lot of fine airborne material over a year, and furnace filters load up faster than in more humid regions. That doesn’t change the price of a cleaning, but it does shape how often a home actually needs one. If you’ve just finished a kitchen remodel or a basement finish, the renovation dust is the trigger, not a calendar date.
Boulder sits at the base of the Flatirons, and the seasonal swing between dry winter air and dry summer air matters to your ducts more than you might think. Low indoor humidity in winter means joints and seams can open slightly, and any gap that opens is a place for dust to bypass the filter. We check for that as part of the inspection, and if we find loose connections we can fix them rather than cleaning around them. That dual capability – cleaning and repair – is the difference between a service call and a lasting one. See the full scope of Boulder Duct Cleaning services if you want the broader picture.
How to Save on HVAC Cleaning
A few practical ways to keep the number down without cutting corners:
- Bundle services when it makes sense. If your dryer vent is due for cleaning and your ducts haven’t been touched in years, getting both in one visit usually costs less than two separate appointments. Ask for it in the estimate request.
- Get the free estimate first. We quote before we start. Call (877) 550-7147 and we’ll talk through your home’s size, system count, and any recent renovation, then give you a written range so there are no surprises on the invoice.
- Deal with repair before it spreads. A disconnected flex run or a crushed section forces air into the wrong place. Fixing it during the cleaning, rather than discovering it later, saves you a second visit.
- Time it after the dust. If you’re mid-renovation, wait until the drywall is finished and the sanding is done. Cleaning before the last of the dust settles means paying twice.
- Keep up with filters. Changing furnace and return filters on a sensible schedule keeps your system from pulling heavily loaded air through the ducts. It’s the cheapest maintenance there is.
- Ask for the full-service scope up front. Guardsman protective treatments, where you want them, and any filtration service should all be in the estimate so you’re comparing complete numbers, not partial ones.
We arrive with professional-grade equipment on every job: Rotobrush contact-cleaning systems for the duct walls and Nikro negative-air/HPEA machines to hold the dust in containment while we work. That’s not a bonus tier – it’s the standard setup. If you’re curious about what a proper cleaning looks like versus a vacuum-and-leave operation, the Boulder service overview walks through the process. Because we run a negative-air machine, the cleaning captures what it dislodges instead of pushing it into your living room.
Dryer Vent Cleaning: The Separate Safety Line Item
Dryer vent cleaning in Boulder runs $120 to $195 for a typical rear-vent installation, and it’s priced separately because it’s a different job with different equipment. We treat it as a fire-safety service, not a convenience add-on. A clogged vent traps lint, and trapped lint is a documented cause of residential fires. We clean the full run, check for crushed or disconnected pipe, and confirm the exterior damper opens and closes properly. If your dryer is taking longer than it used to, that’s the signal to have it checked. Roof-routed vents and long runs fall in the $195 to $325 range.
Air Duct Repair: Priced After We Look
Duct repair typically ranges $200 to $700, and the final number depends entirely on what we find. Common problems include disconnected joints in the attic or crawlspace, crushed flex sections behind drywall, and seams that have lost their seal. We don’t quote repair blind. During the cleaning inspection we note anything damaged and show you before recommending a fix. A clean-only contractor will clean around a disconnected run and leave the problem in place; we fix it, then finish the cleaning. That’s the practical reason to work with a company that does both.
FAQs – HVAC Cleaning Cost
How much does HVAC cleaning cost in Boulder?
Most Boulder homes pay $350 to $650 for a standard single-system cleaning, with the typical figure around $475. Larger homes with two systems or heavy renovation dust run $550 to $1,100. Call (877) 550-7147 for an exact written estimate – estimates are free.
Is it cheaper to repair or replace damaged ductwork?
Repair is almost always the cheaper path when the damage is localized, typically $200 to $700 versus the cost of replacing entire runs. We inspect first, quote the repair after, and only recommend replacement when a section is beyond sealing. Call (877) 550-7147 to get an inspection and a written number.
How much does dryer vent cleaning cost in Boulder?
Dryer vent cleaning runs $120 to $195 for a standard rear-vent install, and $195 to $325 for long or roof-routed runs. It’s a fire-safety service and worth treating as its own line item. Call (877) 550-7147 to add it to your estimate.
Can you come today?
Same-day service is often possible depending on the schedule. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday. Call (877) 550-7147 and we’ll find the next opening for a free estimate.
Why is a $99 duct cleaning quote usually a red flag?
Because proper equipment costs real money to run. A Rotobrush contact-cleaning system and a Nikro negative-air machine aren’t consumer vacuums, and a low quote usually means one pass with inadequate suction and no repair scope. Ask what equipment is being used before you book. Call (877) 550-7147 to compare a complete quote with what you’ve been offered.
Why Equipment and Scope Drive the Number
This is the part most pricing pages skip. The difference between a $400 job and a $700 job is often not the size of the house – it’s what the crew is actually doing. Contact cleaning means the Rotobrush head physically agitates the duct wall to break loose adhered dust, while the Nikro negative-air unit keeps the system under vacuum so the dislodged material goes into HEPA filtration, not into your rooms. That’s the setup we use on every job. When contamination goes beyond household dust – mold spores after a moisture event, fine particulate after a renovation, rodent debris in a crawlspace run – we bring Abatement Technologies equipment rated for that level of work.
Our technicians have up to 9 years of experience, and they’re trained on Honeywell and Aprilaire whole-home filtration systems, which matters if your home runs one of those. Servicing a whole-home filter is not the same as cleaning a register. It’s a different component with its own service requirements, and we handle it as part of the wider scope. If you’re not sure what filtration setup you have, we can identify it during the estimate.

What Our Customers Say
"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
- Megan Parker"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Marisol Castillo"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."
