Maybe you've noticed dust coming back the day after you clean, and you're considering air duct cleaning. Or you saw an ad for "$99 whole-house air duct cleaning" and wondered what that price includes. Either way, before you book a cleaning, you want to know what a fair price looks like.
In this guide, ARS®/Rescue Rooter® breaks down typical prices, the factors that move them up or down, and when repairing your ducts makes more sense than cleaning them. If you're ready to talk to someone now, explore our air duct cleaning services or call 866-399-2885.
How Much Does Air Duct Cleaning Cost?
On average, homeowners pay between about $271 and $509 to have their air ducts cleaned. National cost averages from Angi, as reported by Servpro, put the typical price around $389. Larger homes, homes with more than one HVAC system, and heavily contaminated ducts can cost more.
A standard job usually covers your supply and return ducts, vent covers, and the main parts of the system that air passes through. Think of the national numbers as a starting point, not a quote. Your actual price depends on your home.
How Companies Price the Job
Duct cleaning companies don't all price the same way. Reported per-vent and hourly rates run $25 to $50 per vent and $90 to $130 per hour. Here are the most common pricing models you'll see:
- Per vent: You pay for each supply and return vent. This makes it easy to estimate if you count your vents.
- Hourly: You pay for time on the job. This is common when the scope is hard to predict.
- Per square foot: The price scales with the size of your home. Some companies use this for larger or unusual layouts.
- Flat rate: You pay one price for the whole system. Always ask exactly what that price includes.
Air Duct Cleaning Price Factors
Two homes with the same square footage can get very different quotes. That's because the price is mostly about labor, meaning how much time and equipment the job takes. Here's what moves the number.
| Price Factor | What It Means | How It Affects Cost |
|---|---|---|
| Home size and vent count | More rooms usually mean more vents and longer duct runs | More vents and ductwork mean more labor and a higher price |
| Number of HVAC systems | Some homes have a separate system for each floor or zone | Each system is cleaned on its own, so each one adds cost |
| Type of ductwork | Rigid metal, flexible, or fiberglass-lined ducts | Flexible and lined ducts need more careful handling, which may add time |
| Accessibility | Ducts in tight attics, crawl spaces, or wall cavities | Hard-to-reach ducts take longer, which raises labor costs |
| Contamination level | Light dust versus heavy debris, pests, or mold | Heavier buildup takes longer and may require added services |
| Your location | Labor rates differ from market to market | Prices tend to run higher in areas with a higher cost of living |
Add-On Services and Hidden Costs
Sometimes a technician finds a problem that a standard cleaning won't fix. Other times, a company offers extras you may or may not need. Here are the add-ons homeowners run into most.
- Mold: Visible mold inside the system calls for more than a basic cleaning. The moisture problem that caused it also needs to be fixed, or the mold may come back.
- Pests: Rodent or insect activity should be handled by pest control before the ducts are cleaned.
- Dryer vents: Many homeowners pair duct cleaning with a dryer vent cleaning service, since lint buildup is a separate issue.
- Air purification: If dust or odors keep coming back, a whole-home UV air purifier may help, working alongside your heating and cooling system.
Watch out for the "$99 special." Very low advertised prices often limit the number of vents or skip the main trunk lines, which are the large ducts that feed each room. Extra charges then show up once the crew is in your home. A reputable company provides a clear written estimate before work begins.
What's Included in a Professional Duct Cleaning
When ARS cleans your ducts, the work starts with an inspection. This helps our technicians understand the scope of the problem before they begin.
From there, a typical cleaning includes:
- HEPA-filtered vacuuming: A high-powered vacuum with a HEPA filter pulls dirt from your ductwork. A HEPA filter is designed to trap very fine particles.
- Roto brush cleaning: A rotating brush runs through the ducts to loosen stuck-on dirt.
- Compressed air: Air is used to dislodge any remaining debris so the vacuum can collect it.
- Component cleaning: The team also cleans the evaporator coil, vent covers, and blower motor. These are parts the air moves through every time your system runs.
Is Air Duct Cleaning Worth It?
Duct cleaning is worth it when there's a clear problem to solve, like mold, pests, or heavy dust. EPA duct cleaning guidance states, "EPA does not recommend that the air ducts be cleaned routinely, but only as needed." The EPA also advises getting written estimates from at least three different service providers before you decide.
Signs it may be time to schedule a cleaning:
- You can see mold growth inside the ducts or on other system parts.
- You've found evidence of rodents or insects in the ductwork.
- Dust or debris blows out of your supply vents.
- You recently finished a renovation or moved into a newly built home with leftover drywall dust.
How often you need it depends on your home. For many homes, cleaning every five to seven years on average may be enough. Pets, the number of people in the house, carpeting, and the type of filters you use can all change that timeline.
Clean, Repair, or Replace Your Ducts?
Cleaning removes dirt, but it won't fix a duct that's leaking, crushed, or falling apart. Before you pay for a cleaning, it helps to know which problem you actually have.
Leaks matter more than many homeowners realize. According to ENERGY STAR duct sealing guidance, "In a typical house, however, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts." Cleaning doesn't stop that loss. Sealing or repair does.
| Your Situation | Best Next Step |
|---|---|
| Dust, debris, or pests inside otherwise sound ducts | Clean the ducts |
| Rooms that won't heat or cool evenly, or gaps and loose joints | Repair or seal the affected sections |
| Crushed, torn, or disconnected runs in a few spots | Repair those sections |
| Widespread damage, very old ductwork, or a poor layout | Consider replacement, often alongside an HVAC upgrade |
According to ARS service data, ductwork repair or replacement typically runs between about $2,800 and $4,000 per job, depending on the extent of the work and your home's layout. That's a bigger investment than a cleaning, so an inspection is worth it first.

How to Hire a Duct Cleaner and Compare Quotes
The lowest quote isn't always the best value. Compare what each company will actually do, not just the bottom line.
Check each quote for:
- Scope: Does it include supply and return trunk lines, the blower, and every vent?
- Process: What equipment will they use, and will they show you the contamination before and after?
- Standards: Ask whether they follow NADCA's ACR cleaning standard, which, in NADCA's words, "provides comprehensive guidance for assessing and cleaning HVAC systems, and cleanliness verification."
- Claims: Be cautious of sweeping promises about health benefits. Also note that the EPA doesn't certify or endorse duct cleaning companies, so an "EPA-certified" claim is a red flag.
How to Save on Air Duct Cleaning
A few simple habits may help you keep costs down and stretch the time between cleanings.
Tips that work:
- Change your filter on schedule. Replacing it about every three months, as a general rule, may help keep dust out of your ducts. Here's how often to change filters based on your home.
- Bundle services. Ask about scheduling duct cleaning alongside an HVAC tune-up or dryer vent service.
- Ask about payment options. ARS offers flexible financing options for qualifying customers.
- Clean when needed. Following the "as needed" approach keeps you from paying for cleanings your home doesn't require.
