How Much Does Air Duct Cleaning Cost? (2026 Prices)

The short answer

A typical professional cleaning runs $270 to $500, with a national average of $389, per NerdWallet. NADCA, the industry’s trade association, puts a thorough cleaning for an average-sized home at $450 to $1,000, and This Old House lands in the same band. These are typical ranges from published 2025-2026 research, not quotes for your house.

The detail almost every published range skips: it assumes a typical home with one HVAC system. A home with two furnaces or air handlers has two separate duct networks, and operators price the second one as nearly a second job. One operator in our 2026 pricing research publishes $550 to $700 per furnace with 10% off the second; across the providers in this directory, a full two-system cleaning commonly lands at $800 to $1,000. That’s normal pricing, not a markup.

Typical 2026 prices

Figures below come from national research published by NerdWallet, This Old House, and NADCA, plus our own 2026 pricing research across the providers in this directory.

What you’re pricing	Typical cost
One HVAC system, national average	$389
One HVAC system, common range	$270-$500
Thorough cleaning, average-sized home (one system)	$450-$1,000
Two-system home (our directory research)	$800-$1,000+
Per supply vent	$25-$50
Per return vent	$40-$75
Per square foot of home	$0.15-$0.40
Dryer vent cleaning, added to the visit	$100-$150 (about $75-$340 booked alone)

Some providers price per vent or per square foot instead of per system. None of these bases is a red flag by itself. What matters is that the basis is stated before the crew shows up.

What moves the price

The number of HVAC systems matters most. Each furnace or air handler feeds its own duct network, and each network is a separate job with its own setup and its own hours. A whole-house price that doesn’t say how many systems it covers isn’t a price yet.

Home size comes second. More square footage means more vents and more trunk line, which is why per-square-foot pricing exists at all. A 3,500 sq ft house takes longer than a 1,400 sq ft house even on a single system.

Access is the quiet cost driver. Ducts above finished ceilings, runs through a tight crawl space, or an air handler wedged into a closet all add hours. Hours are what you’re paying for.

Then there’s what’s actually in the ducts. Construction debris after a remodel, or signs of animals, means containment work and slower progress. Expect the high end of the range, and get the reason on the quote.

Region shifts all of the above. In our pricing research, high-cost coastal metros run about 10% to 40% over the national midpoints, while much of the Midwest and South runs 10% to 25% under.

The $49 special, explained

The $49 whole-house ad is not a price. It’s below what it costs to send a truck and a crew to your address, which means the visit has to make its money another way. It usually goes one of two directions. The crew “finds mold” and the job jumps to $500 to $2,000 on the spot. Or you get 45 minutes of register dusting that leaves the actual ductwork untouched.

The math is the tell. A real cleaning uses truck-mounted or portable HEPA negative-pressure vacuums, and NerdWallet’s published estimates put a full professional job at three to eight hours, with labor at $90 to $125 an hour. Even the shortest honest job carries more labor cost than $49 covers, before the truck and the equipment. NADCA itself warns against suspiciously low offers, which tend to skip the air handler, the blower fan, and the coils. Anything whole-house under about $200 is an ad for an upsell. Read it that way and move on.

Before you pay: is it even worth it?

It depends on what’s actually going on in your ducts, and knowing that before you book is how you avoid paying for the wrong job. The EPA doesn’t recommend cleaning on a fixed schedule — its position is that duct cleaning has never been shown to prevent health problems — so the smart move is to match the job to a real trigger, not a calendar.

The real triggers are specific. The EPA’s list: visible mold growth inside the ducts or on other parts of the system, a rodent or insect infestation, or ducts clogged with enough debris that it’s blowing into your rooms. Construction dust after a remodel behaves the same way. If one of those describes your house, the job is worth doing — request quotes from a couple of providers and have them show you what they find before and after. If none do, start with a filter change and save the cleaning for when a real trigger shows up.

How to pay a fair price

1. Get the price per system, in writing, before anyone shows up. Ask directly: is that for one system or the whole house, and how many systems do I have? A provider who won’t put it on paper is telling you how the visit will go.
2. Make the inspection come before the final number. A fair provider looks at your ducts, then prices the job. A firm number quoted sight unseen is a guess. A $49 number quoted sight unseen is bait.
3. Bundle the dryer vent. Booked alone, dryer vent cleaning runs $75 to $340. Added to a duct cleaning visit, it typically drops to $100 to $150.
4. Request quotes from two or three providers near you and put the same questions to each. Check that every quote prices the same scope: how many systems, which vents, what equipment.
5. Skip add-ons without a stated, shown reason. Mold claims deserve photos and, per the EPA, expert or lab confirmation, since plenty of things look like mold and aren’t. Sanitizer fogging, “antimicrobial treatment,” and UV lights are upsells until someone explains what problem in your ducts they fix.
