AfterHow Much Does Air Quality & Sanitizing Cost in Boulder?
Air quality and sanitizing work in Boulder typically runs $350 to $1,400 for a home, depending on square footage, how many duct runs are involved, and whether the job is routine cleaning with a treatment or a contamination-level project that calls for negative-air containment. A single-system whole-home cleaning with a Guardsman protective treatment usually lands between $400 and $700. Projects that include filtration upgrades or mold-spore remediation push toward the top of the range.
Homeowners and property managers around Boulder tend to book this work after a trigger: allergy season, a renovation that left fine dust in the returns, or a dryer that’s been running hot. If you’re weighing a quote, call (877) 550-7147 for a free estimate. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday.
Key Takeaways
- Routine whole-home air duct cleaning with a sanitizing treatment in Boulder usually costs $350 – $700.
- Contamination-level work using Abatement Technologies equipment (mold spores, fine particulates) can run $900 – $2,500 depending on scope.
- Air duct repair, when damaged runs are found, adds $150 – $600 on top of cleaning.
- Dryer vent cleaning as a standalone fire-safety service is typically $125 – $225.
- Your written estimate sets the final price. Free estimates, no surprises.
Air Quality & Sanitizing Cost Breakdown (2026)
Here’s what the line items look like for a typical Boulder home. These are estimated ranges; the written estimate you receive after we look at your system is what sets the final price.
| Service / Line Item | Typical Estimated Range (Boulder, 2026) |
|---|---|
| Whole-home air duct cleaning (up to ~2,000 sq ft, up to 12 runs) | $350 – $650 |
| Additional duct runs beyond 12 | $15 – $30 each |
| Sanitizing / antimicrobial treatment (per system) | $100 – $250 |
| Guardsman protective treatment (full-service scope) | $80 – $175 |
| Dryer vent cleaning (standalone fire-safety service) | $125 – $225 |
| Air duct repair (per damaged run or joint) | $150 – $600 |
| Contamination-level cleaning with negative-air HEPA containment (Abatement Technologies) | $900 – $2,500 |
| Honeywell or Aprilaire filtration system service or filter change | $75 – $300 |
What pushes the number up: square footage, the number of supply and return runs, whether the ductwork is accessible or buried behind finished ceilings, and whether the system has visible contamination (mold spores or heavy fine particulate) that warrants Abatement Technologies equipment and negative-air containment. What pulls it down: a small home with a tight, accessible duct system that only needs standard contact cleaning with a Rotobrush machine and no repairs. We clean and we repair, so if a joint is failing or a run has separated, we fix it in the same visit rather than clean around a problem.
Routine Cleaning vs. Contamination-Level Work
These are two genuinely different jobs, and the pricing reflects that. Routine cleaning is contact cleaning with a Rotobrush system plus a Nikro negative-air HEPA machine holding dust down while we work. It’s appropriate for a home that just wants clean air and a fresh treatment. Contamination-level work, by contrast, is for situations where mold spores or fine particulates have colonized the system. That’s where Abatement Technologies equipment comes in, and it’s where the price climbs into four figures. A good contractor will tell you which one you actually need. We’d rather quote you the right job than the biggest one.
If you’re not sure which you’re dealing with, Boulder Duct Cleaning starts with a look at your system before any estimate.
What Affects Air Quality & Sanitizing Pricing in Boulder
- Home size and duct count. Most Boulder homes have between 8 and 20 supply and return runs. The price scales directly with the number of runs, since each one gets contact-cleaned individually with the Rotobrush.
- Duct accessibility. Ductwork in a finished basement ceiling or a tight crawlspace takes longer to reach. Older homes with retrofitted systems are often the slowest jobs.
- Filtration system type. Homes running Honeywell or Aprilaire whole-home filtration are usually in better shape and need less remediation, but servicing those systems requires the right parts and familiarity. We’re trained on both brands, so we don’t hand it back to you.
- Dust source after a renovation. Boulder has a lot of older homes that get gut-renovated. Drywall dust and construction particulate get pulled straight into the returns and settle deep in the runs. Post-renovation cleaning is its own category, and it costs more than a routine clean because there’s simply more to remove.
- Whether repair is needed. Loose joints, disconnected runs, and crushed flex duct all reduce airflow and re-contaminate a clean system. If we find damage during cleaning, repair adds to the bill but saves you from cleaning the same ducts twice.
- Broadband trigger. Homes that see a lot of windblown dust from the surrounding open space, or that burn wood in winter, load up faster and may need more frequent cleaning. That’s a scheduling decision more than a pricing one, but it changes what a fair quote looks like.
How to Save on Air Quality & Sanitizing
The single biggest lever is avoiding the wrong job. If your ducts only need routine cleaning, don’t pay for contamination-level remediation. And if the ducts are damaged, don’t pay to clean a system that will just re-soil in a few months. Getting an honest scope is where savings actually come from.
- Bundle dryer vent cleaning with air duct cleaning. Doing both in one visit saves the setup time and travel of two separate appointments. It’s a fire-safety service, not an add-on, and it makes sense to knock both out together.
- Fix repairs while we’re there. A damaged run discovered during cleaning is far cheaper to fix in that visit than to book a separate appointment later.
- Keep filters current. Regular filter changes protect your Honeywell or Aprilaire system and reduce the load the ducts carry. A $15 filter change beats a $500 deep clean every time.
- Get a written estimate before work starts. Free estimates let you compare honestly. Call (877) 550-7147 and we’ll put a scope on paper so you know exactly what you’re paying for.
Why Equipment Choice Changes the Price
A low bid and a serious bid for the same job usually differ in one place: the machine. Consumer vacuums dressed up as duct-cleaning rigs don’t generate the suction to lift settled dust from a 20-foot run, and they don’t contain what they dislodge. Our crews run Rotobrush contact-cleaning systems and Nikro negative-air HEPA equipment, the same grade of machines restoration contractors use. That’s why the pricing reflects a real clean. When contamination calls for it, Abatement Technologies equipment lets us handle mold-spore and fine-particulate jobs properly, with real containment instead of a promise.
Across Boulder, homes come with different duct layouts, different filtration setups, and different histories. What we bring to each one is the same: verify the system, match the equipment to the job, quote it fairly, and finish the work. If you’re in a different market, our Boulder pricing guide lays out the same cost structure we apply locally.
What We Check Before Quoting
A hands-on look before pricing keeps the estimate honest. It includes:
- Supply and return run count, and whether each is reachable.
- Signs of mold or fine particulate that would call for Abatement Technologies containment.
- The state of the filtration system, and whether it’s a Honeywell or Aprilaire setup.
- Joint integrity and flex duct condition, so we catch repair needs before we clean.
- Dryer vent routing if you want it cleaned in the same visit.
FAQs – Air Quality & Sanitizing Cost
How much does whole-home air duct cleaning cost in Boulder?
Whole-home air duct cleaning in Boulder typically costs $350 – $650 for a system with up to 12 runs, and $15 – $30 for each run beyond that. Sanitizing treatment adds $100 – $250. Call (877) 550-7147 for an exact quote, estimates are free.
When does air quality work need to cost more than routine cleaning?
It needs to cost more, often $900 – $2,500, when a system shows mold spores or heavy fine particulate that requires negativ-air HEPA containment and Abatement Technologies equipment. If the ducts just need routine Rotobrush contact cleaning, you shouldn’t be paying contamination-level prices. Call (877) 550-7147 and we’ll scope it honestly.
How much does air duct repair cost in Boulder?
Air duct repair in Boulder usually runs $150 – $600 per damaged run or joint, depending on access and whether the run is flex or rigid. Repair is a dedicated service, not an afterthought, and doing it before or during cleaning prevents re-contamination. Call (877) 550-7147 for a free repair estimate.
Is it cheaper to clean dryer vents alongside air ducts, or separately?
Cheaper together. Dryer vent cleaning on its own runs $125 – $225, and pairing it with air duct cleaning in the same visit avoids a second dispatch. It’s a fire-safety service with its own tools and process, so it’s worth doing right. Call (877) 550-7147 to schedule both.
How much does Honeywell or Aprilaire filtration service cost?
Servicing a Honeywell or Aprilaire whole-home filtration system typically costs $75 – $300, depending on the filter and the work involved. These systems need brand-appropriate parts, and we’re trained on both. 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."
