AfterHow Much Does Air Duct Cleaning Cost in Boulder?
Air duct cleaning in Boulder typically costs $350 to $750 for a standard home, with most single-family houses landing in the $450 to $600 range. Larger homes with multiple systems, heavy contamination, or added services like dryer vent cleaning run $750 to $1,200. The final number depends on your home’s square footage, how many duct runs you have, and how much build-up the system is carrying.
Boulder County homes deal with a specific mix of dust sources: dry Front Range air, spring pollen from the foothills, and fine particulate that settles after wildfire smoke events along the Flatirons. That combination means duct cleaning here often addresses more than simple household dust. We approach every job with professional equipment, not consumer vacuums dressed up as duct-cleaning rigs, and we’ll tell you plainly what your system actually needs.
Key Takeaways
- Typical air duct cleaning in Boulder runs $350 to $750 for most homes.
- Add-ons like dryer vent cleaning and air duct repair move the total toward $750 to $1,200.
- Number of vents, system size, and contamination level drive most of the price difference.
- We clean and we repair, so damaged ductwork doesn’t get cleaned around and left in place.
- Free estimates, and the written estimate sets the final price.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how the line items stack up for Boulder homeowners. These are typical ranges for the local market; your written estimate pins down the exact figure once we’ve seen the system.
| Service | Typical Price Range | What It Covers |
|---|---|---|
| Standard air duct cleaning (whole home) | $350 – $750 | Contact-cleaning of supply and return runs, registers, grilles, and main trunks |
| Base cleaning for smaller homes (under ~1,200 sq ft) | $300 – $450 | Fewer runs, single system, routine dust load |
| Larger homes or multiple HVAC systems | $650 – $1,000 | More runs, multiple air handlers, longer trunk lines |
| Negative-air HEPA setup for heavy contamination | $150 – $300 added | Abatement Technologies and Nikro negative-air equipment for mold spores, renovation dust, fine particulate |
| Dryer vent cleaning (separate service) | $120 – $225 | Full lint removal from vent run and termination, dedicated fire-safety service |
| Air duct repair (sealing, reconnecting, patching) | $200 – $900 depending on scope | Fixing disconnected joints, crushed flex runs, leaks, and damaged sections |
| Protective treatment (Guardsman) | $80 – $200 added | Optional protective application after cleaning, part of the full-service scope |
What pushes a Boulder job toward the high end? Usually one of four things: more vents than average, a second HVAC system, visible contamination (mold spores, drywall dust after a remodel), or ductwork that’s damaged and needs repair before or after cleaning. A run-of-the-mill home with a single system and routine dust should land well within the standard range. We use Rotobrush contact-cleaning systems on every job, so the cleaning itself is consistent – the variable is the scope of your particular system.
What Affects Air Duct Cleaning Pricing in Boulder
No two Boulder homes have identical ductwork, and the price reflects that. Here are the factors that move the number most:
- Number of vents and runs. A 1,200-square-foot home might have 8 or 10 supply registers; a 2,800-square-foot house in a neighborhood like North Boulder or Table Mesa might have 18 or more. Each run takes time and equipment, so vent count is the single biggest driver.
- System size and how many air handlers. Homes with two HVAC systems (common in larger properties and finished basements) take roughly double the work. This shows up clearly in the larger-home range above.
- Contamination level. Routine household dust is straightforward. Post-renovation drywall dust, mold spores from a moisture problem, or heavy fine particulate from wildfire seasons need negative-air HEPA equipment – that’s where Abatement Technologies and Nikro machines come in. We pull the contaminants out rather than blowing them into the living space.
- Ductwork condition. Crushed flex runs, disconnected joints, and leaks aren’t just inefficiency – they let dust back into the airstream. If we find damage during cleaning, we’ll flag it and quote the repair separately so you can decide. That’s why air duct repair is its own service for us.
- Accessibility. Ducts in tight crawlspaces, behind finished ceilings, or in older homes with unusual routing take longer to reach and clean properly. Boulder’s mix of mid-century homes and newer builds means we see a wide range of layouts.
- Whole-home filtration systems. If your home runs a Honeywell or Aprilaire system, we service and work with those, and cleaning needs to account for the filter housing and inline components rather than treating the ductwork as an isolated run.
One thing we won’t do is quote low and pad the bill later. The estimate is free, and the written estimate sets the price. You’ll know the scope before we start.
How to Save on Air Duct Cleaning
There’s no magic discount that beats a clear scope, but a few habits keep the cost reasonable:
- Clean at the right intervals. Most homes need duct cleaning every 3 to 5 years, not every year. If you just had a renovation, moved into a home with unknown history, or notice visible dust blowing from registers, that’s a better trigger than a calendar.
- Combine services when they’re actually due. If your dryer vent needs cleaning (and it should be checked as a fire-safety service, not an afterthought) and your ducts are due, doing both in one visit is more efficient than two separate appointments.
- Fix leaks while you’re at it. A duct system with disconnected joints is leaking the air you paid to heat or cool. Getting the repair done alongside cleaning saves you a second visit down the line.
- Change your filter on schedule. A clean filter keeps the system from loading up with dust as fast. It’s the simplest thing you can do between professional cleanings.
- Get the estimate in writing before you commit. Free estimates mean no cost to find out. Call (877) 550-7147 and we’ll walk through what your system needs.
Why Equipment Changes What You’re Paying For
A low bid often means a shop vac and a promise. Air duct cleaning done with the wrong tools can actually stir up debris and leave it in the system. We use Rotobrush contact-cleaning systems, which put a rotating brush and vacuum in direct contact with the duct walls, and Nikro negative-air and HEPA equipment to capture what’s loosened. It’s the same class of equipment restoration contractors use, and it’s what lets us handle contamination-level situations rather than just surface dust.
We also clean and repair. If a run is crushed or a joint has come apart, we can fix it – which means you’re not paying to clean a system that’s still leaking. And because we service Honeywell and Aprilaire whole-home filtration systems, we understand how the ductwork, filter housing, and equipment work together. See exactly what we use and why the next time you need air duct cleaning.
Should You Repair or Replace Damaged Ductwork?
In most cases, repair is the more sensible path. A disconnected joint, a crushed section of flex duct, or a leaking seam can usually be fixed for a fraction of what a full replacement would cost. Replacement makes sense when the ductwork is extensive damaged beyond repair or the layout itself is the problem. We’ll give you a straight assessment rather than steering you toward the bigger job.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Boulder?
Most Boulder homes fall between $350 and $750, with a typical single-family house running $450 to $600. Larger homes or multiple systems push it toward $1,000. Call (877) 550-7147 for an exact quote; estimates are free.
Is air duct cleaning worth the money in Boulder?
It’s worth it if you have a specific reason: recent renovation dust, allergy symptoms, a new home with an unknown history, or visible dust from vents. Routine dust alone is a judgment call. Given Boulder’s dry air, foothills pollen, and wildfire-season particulate, many homeowners find the fine dust load noticeable. Call (877) 550-7147 and we’ll tell you honestly whether your system needs it.
How long does air duct cleaning take?
A standard home takes about 2 to 4 hours depending on vent count and system size. Homes with heavy contamination, multiple systems, or add-on services like dryer vent cleaning or repair take longer. Call (877) 550-7147 to schedule and we’ll give you a time window.
Does duct cleaning include the dryer vent?
No, dryer vent cleaning is a separate service, typically $120 to $225. We keep it separate because it’s a fire-safety job with its own process and equipment, not a tacked-on upsell. If you want both, we’ll quote them clearly. Call (877) 550-7147.
Can you repair damaged ducts during the cleaning visit?
Often, yes. We identify damaged or disconnected ductwork while cleaning and can quote the repair. Scope varies from a simple reconnection to larger patches, typically $200 to $900 depending on what’s needed. Call (877) 550-7147 for a free 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."
