Air Duct Cleaning Cost Breakdown (2026)
Here’s how the line items stack up for a typical St. George home. These are estimated ranges for our market; the exact figure depends on what we find when we inspect the system.
| Service | Typical Estimated Range | What It Covers |
|---|---|---|
| Single-system air duct cleaning (up to 10 vents) | $300 – $450 | Supply and return cleaning with rotary brush contact cleaning and HEPA vacuum capture |
| Larger home (11 to 20 vents) | $450 – $650 | Same method, more runs and more registers |
| Large or multi-zone system (20+ vents) | $650 – $900 | Multiple zones, longer trunk lines, more access points |
| Heavy buildup or post-renovation cleaning | Add $100 – $300 | Drywall dust, construction debris, decades of settled dust |
| Air duct repair (disconnected or crushed run) | $150 – $600 | Reconnecting, re-sealing or replacing a damaged section |
| Dryer vent cleaning | $90 – $165 | Full lint removal from the vent run, fire-safety focused |
| Second system or separate HVAC unit | Add $250 – $450 | Homes running two air handlers |
| Filter and IAQ consultation | Included with cleaning | Walkthrough of Honeywell and Aprilaire filtration options |
What pushes a quote toward the top of those ranges? Vents you can’t easily reach, a system that’s never been cleaned, flex duct that’s collapsed in an attic run, or a home with two separate HVAC systems. What keeps it low is straightforward access, a moderate vent count, and ductwork that’s structurally sound. If you’re weighing a full clean against a quick patch, our air duct cleaning page covers the method in detail.
The method matters to the price and to the result. We use Rotobrush contact-cleaning systems, which means a rotary brush physically contacts the duct walls while a Nikro HEPA vacuum captures what gets dislodged. That’s the difference between cleaning and blowing dust back into your living room. Operators running a consumer-grade blower can quote lower because they’re doing less.
What Affects Air Duct Cleaning Pricing in St. George
St. George has some specific conditions that shape duct cleaning quotes. Here’s what actually moves the number.
- Vent count and system size. A 1,400 square foot home with eight vents and a 3,200 square foot home with eighteen vents are different jobs. Most pricing scales with the number of registers and the length of the trunk runs, not just square footage.
- Dust volume and local conditions. Washington County sits in a high-desert basin where spring and summer wind carries fine dust that finds its way into return registers. Homes near open lots, dirt roads or ongoing construction in the St. George valley tend to need more aggressive cleaning, which adds $100 to $300.
- Duct condition. Flex duct that’s sagging, crushed, or disconnected at a joint is common in attics here, where summer attic temperatures are extreme. Cleaning a duct system with a broken connection just spreads dust into the attic. Repair has to come first, and that’s a separate line item.
- Accessibility. Vaulted ceilings, tight attic spaces, and registers tucked behind furniture all add labor time. Homes in neighborhoods like Bloomington and Little Valley often have multi-level layouts that slow the work down.
- Whether the system has ever been cleaned. A first-time cleaning on a home that’s had years of dust accumulation takes longer than a maintenance clean on ductwork serviced regularly.
- Added services. Dryer vent cleaning, second systems, and filter upgrades each add to the total. We quote them separately so you can see exactly what you’re paying for.
How Much Does Air Duct Repair Add to the Bill?
Air duct repair typically adds $150 to $600 to a cleaning job, and it’s often the reason a cleaning alone won’t fix the problem. A disconnected duct in an attic or crawlspace means conditioned air is escaping before it reaches your rooms. You’ll see it on your energy bill before you see it anywhere else.
We treat repair as a core service, not an upsell. When we find a crushed flex run or a joint that’s pulled apart, we quote the repair alongside the clean so you’re not paying for a second visit later. Sealing it properly afterward is part of finishing the job. Ductwork that leaks is ductwork that will collect dust again faster, and that’s true in St. George’s dry climate as much as anywhere.

How Much Does Dryer Vent Cleaning Cost in St. George?
Dryer vent cleaning in St. George typically runs $90 to $165. It’s a small line item next to a house fire, which is the reason we include it in our service mix even though many HVAC-only cleaners don’t.
Lint accumulates in the vent run and restricts airflow. A dryer that takes two cycles to dry a load is a dryer that’s telling you the vent is clogged. In a hot, dry climate like ours, that heat has nowhere to go. We clean the full run, not just the section behind the dryer, and we check for crushed or kinked venting while we’re in there. If you’re already having the ducts cleaned, bundling the dryer vent into the same visit is the sensible way to handle it.
What Affects the Price of Duct Cleaning in a Rental or Commercial Property?
Rental properties and commercial spaces are priced per system and per vent count, same as a home, but the variables shift. Multiple units under one roof, repeated turnover cleanings, and shared ductwork between suites all change the scope. Property managers in St. George with a portfolio of rentals often want a consistent baseline clean between tenants, and we quote those jobs system-by-system so the numbers are predictable.
For commercial spaces, containment-level work sometimes comes into play. We work with Abatement Technologies equipment when the air quality challenge goes beyond routine maintenance, which lets us handle jobs that a standard duct cleaning setup can’t.
How to Save on Air Duct Cleaning
There’s no coupon needed to lower your price. A few practical moves do more than any promotion.
- Bundle the dryer vent. Having the dryer vent cleaned during the same visit costs less than scheduling it separately, since the equipment and travel are already there.
- Fix repair issues at the same time as the clean. A disconnected duct found during cleaning is cheaper to fix on that visit than to book as a return trip. It also means the cleaning actually holds.
- Keep filters changed. A clogged filter forces the system to work harder and pushes more dust into the ductwork. Changing it on schedule is the cheapest maintenance you can do.
- Address the source, not just the symptom. If you’re near construction or a dirt lot, sealing return registers and keeping windows closed during windy periods reduces how fast dust accumulates again.
- Get a written estimate before work begins. It costs nothing, and it prevents the surprise line items that low-bid operators add once the job starts.
We don’t run limited-time promotions. We give you a straight estimate and you decide. Call (855) 419-9402 for a free one.
Is Air Duct Cleaning Worth the Cost in St. George?
For most homes, yes, if there’s a real reason to do it. Visible dust blowing from registers, a recent renovation, a musty smell when the system kicks on, or ductwork that’s never been cleaned in a home you just bought are all legitimate triggers. Cleaning with a contact method and HEPA capture also lets us find repair problems that wouldn’t surface otherwise.
If your ducts were cleaned two years ago and you keep up with filters, you probably don’t need it yet. We’ll tell you that on the estimate rather than sell you a cleaning you don’t need.
Why the Method Matters More Than the Quote
Two quotes that differ by $200 often differ by the equipment behind them. A blower with no real vacuum attachment stirs dust loose and leaves it in the system. Our technicians have up to 10 years of experience and work with Rotobrush contact-cleaning systems, Nikro HEPA vacuums, and Abatement Technologies equipment, which is the same class of tooling used in commercial and remediation work. That’s part of why we hold the line on method. We also work with Guardsman protective products so the surfaces we clean stay protected afterward.
We’re also fluent in the filtration side. If you’re considering a Honeywell or Aprilaire system, we can talk through what fits your ductwork and your goals alongside the cleaning visit. And because we handle cleaning, repair, and dryer vent safety under one roof, you’re not coordinating three contractors for problems that connect to each other.
