AfterHow Much Does Air Duct Cleaning Cost in Miami?
Our Air Duct Cleaning services in Miami typically cost between $350 and $700 for an average single-family home, which lands right at the national midpoint of about $450. Larger homes above 2,800 square feet, older systems with heavy buildup, and jobs that include dryer vent cleaning or duct sealing will push that number toward $900 or more. You can get a firm written price before any work starts by calling Hollis Air Duct Miami at (850) 660-3272.
Those ranges are real numbers for the Miami market in 2026, not a teaser rate that changes once a crew shows up. The price you’re quoted is the price on the invoice. We put it in writing before we touch a single vent.
Key Takeaways: Miami Air Duct Cleaning Costs (2026)
- Typical single-family home (up to 2,000 sq ft): $350 – $500
- Larger home (2,000 – 3,500 sq ft): $450 – $700
- Full system with dryer vent and sanitizing: $600 – $900
- Duct sealing add-on: $300 – $800 depending on duct count and access
- Most Miami jobs: completed in 3 to 6 hours, same day
Air Duct Cleaning Cost Breakdown (2026)
Here’s what a Miami homeowner should expect to see on a written estimate. These are line-item ranges based on what we price across the metro area, from Kendall and Doral up through Miramar and Homestead.
| Service Line Item | Typical Cost Range in Miami |
|---|---|
| Full air duct cleaning (up to 10 vents) | $350 – $500 |
| Each additional vent beyond 10 | $15 – $25 per vent |
| Main trunk line cleaning (included in full service) | $0 – $150 if quoted separately |
| Dryer vent cleaning (standalone or add-on) | $100 – $175 |
| Air handler / blower compartment cleaning | $100 – $175 |
| Sanitizing fog treatment | $150 – $300 |
| Duct sealing (mastic, per duct run) | $35 – $65 per run |
| Whole-home duct sealing package | $300 – $800 |
Two things move the price more than anything else in Miami: the size of the system and how long it’s been since the last cleaning. A three-bedroom house in West Kendall that hasn’t had its ducts touched in a decade will take longer and cost more than a two-bedroom condo in Brickell cleaned two years ago. Access matters too. Attic ductwork in a 1950s Coral Gables house with a low-pitch roof runs slower than a 2015 build in Doral with a walk-in attic.
The negative-air method is the professional standard for air duct cleaning. A Nikro negative-air machine connects to the duct system and pulls a vacuum on the entire network while agitation tools loosen debris inside the runs. That’s what you’re paying for: capture and removal, not just blowing dust around. Hollis runs Rotobrush rotary brush systems alongside negative-air units, which gives us the mechanical agitation to break loose the crusted-on film that builds up inside AC ducts in humid climates.
What Affects Air Duct Cleaning Pricing in Miami
- Home size and vent count. More square footage means more duct runs, more registers, and more time on the job. The county average home in Miami-Dade runs between 1,200 and 2,500 square feet, but a Pinecrest estate with 20 vents is a different job than a Little Havana bungalow with 8.
- How long since the last cleaning. The National Air Duct Cleaners Association recommends cleaning every 3 to 5 years. Homes that have gone 10 or more years, especially with pets or recent renovation work, typically need a second pass on the main trunk line.
- Mold and humidity. Miami’s humidity is aggressive. Duct interiors that stay damp become a growth surface. If our technicians find visible mold on the interior of the ductwork, that changes the scope: some components may need replacement rather than cleaning, and we’ll show you what we found before we recommend anything.
- Access conditions. Attic access, crawlspace depth, and whether the air handler sits in a closet or the garage all affect labor time. A townhouse in Edgewater with the air handler in a tight interior closet takes longer than a suburban single-story with garage-mounted equipment.
- System condition. Leaky ducts with disconnected joints or separated runs need repair work before cleaning makes sense. Cleaning a duct system that’s leaking 30% of its airflow into the attic is wasted effort. That’s why we assess seal integrity first.
- Add-on services. Dryer vent cleaning, sanitizing fog, and duct sealing each add to the ticket. Bundle them with a full cleaning and you pay less than scheduling each one separately.
Is Duct Sealing Included in Air Duct Cleaning?
No. Duct sealing is a separate service that can run $300 to $800 on top of a cleaning, depending on how many runs need mastic and how accessible they are. Duct sealing uses a brush-on or spray-on mastic compound to close gaps at joints, elbows, and takeoffs where conditioned air leaks into unconditioned space. In a hot attic in July, a leaking duct is dumping cooled air into 130-degree heat. Sealed ducts move the air you’re paying to cool into the rooms where you actually live.
Hollis includes a duct-integrity check with every cleaning. If we find leaks, we’ll show you the gaps with a camera and give you a sealed-duct price in writing. You decide whether to do it same-day or schedule it later. Either way, the price doesn’t change from what’s on the paper.
How Much Does Air Duct Cleaning Cost in Miami?
This is the short answer to How Much Does Air Duct Cleaning Cost in Miami Gardens, FL? (2026 Price Guide): $350 to $700 for most single-family homes in Miami, with larger homes and heavier buildup pushing toward $900 or more. Condos and townhomes with shorter duct runs often come in under $400. The only way to get an exact number for your house is a quick assessment of your system size, vent count, and access setup.
Hollis Air Duct Miami air duct cleaning gives free estimates by phone. Tell us your square footage and vent count, and we’ll give you a price range before we ever schedule the visit. The written quote you get before the job is the price you pay when we’re done. No door-knock repricing, no surprise “mold treatment” upsell once the blower’s pulled.
How Much Does Dryer Vent Cleaning Cost in Miami?
Dryer vent cleaning in Miami runs $100 to $175 as a standalone service, and $75 to $125 when bundled with a full Air Duct Cleaning Near Me in Miami, FL. Clogged dryer vents are a leading cause of house fires in the U.S., and Miami’s humid air makes lint stick to vent walls faster than in dry climates. It’s not a fire risk anyone should gamble on, and it’s a cheap service relative to what it prevents.
Our technicians run a rotary brush through the full vent length and check the exterior termination point. In condo buildings along Brickell Avenue or in older Miami Beach structures, vents often run 15 to 30 feet with multiple bends. Those take longer and cost toward the top of the range.
How Often Should You Clean Air Ducts in Miami?
Every 3 to 5 years for most Miami homes. If you have pets that shed, a smoker in the house, recent drywall or flooring work, or anyone with allergies or asthma, lean toward every 2 to 3 years. Coastal homes face one more factor: salt air. Salt crystals build up on duct interiors faster in Miami Beach, Key Biscayne, and anything east of US-1, which means those homes often need cleaning a year sooner than inland neighborhoods.
The 3-to-5-year cadence is the same window the National Air Duct Cleaners Association uses. It’s a guardrail, not a rule. A homeowner in Doral with two German shepherds and a 12-year-old AC system should be on the shorter end. A part-time snowbird in Aventura who’s only in the unit four months a year can stretch it longer.
What Are the Signs Your Ducts Need Cleaning?
- Dust returns within days of cleaning surfaces. If you wipe down a dresser and it’s coated again in 48 hours, the ducts are recirculating debris.
- Vents show visible dust buildup or black streaks. The streaks around register edges are typically dust particles blown outward by airflow.
- You smell a musty odor when the AC kicks on. That’s organic material in the ducts or air handler, common in Miami’s humidity.
- You’ve had renovation work done. Drywall dust, paint overspray, and flooring debris get pulled into the return ducts and coat the entire system.
- Your energy bill crept up without a matching rate increase. Restricted airflow forces the blower to run longer, which costs money every month.
- Family members have unexplained allergy symptoms indoors. Dirty ducts circulate pollen, pet dander, and dust mite debris through every room.
Any of those signs is a reason to call for an assessment. Not all of them are a reason to clean that week. A good technician will tell you the difference, and that’s exactly how Hollis trains our people to operate.
Negative-Air vs. Rotary Brush: What’s the Difference and Does It Matter for Cost?
Two main methods dominate professional air duct cleaning. The negative-air method connects a powerful vacuum unit to the duct system, creating suction that pulls dislodged debris into a HEPA-filtered capture system while agitation tools scrape the duct walls. The rotary brush method feeds a spinning brush through each run to mechanically scrub the interior, with a negative-air unit capturing what comes loose.
In Miami, where humidity combines with fine dust to create a stubborn film on duct interiors, the strongest approach is both. That’s what Hollis runs: Rotobrush rotary brush systems for mechanical agitation paired with Nikro negative-air machines for capture. You get the scrubbing benefit of a brush with the containment of a vacuum. Cookie-cutter companies that only run a vacuum line without agitation will leave behind the film that’s actually holding the dust in place, and you’ll be paying for another cleaning in two years.
Does the method change the price? Not significantly. A thorough job with either method should fall in the $350 to $700 range. The difference is in the result, not the invoice. A cheap vacuum-only pass is why Miami has so many homeowners who say duct cleaning “didn’t do anything.”
How We Price Jobs: The Garrison Standard
Hollis Air Duct Miami runs on the Garrison Standard, which is the operating rulebook for every business in the Garrison Partners family. The short version: written prices before work begins, technicians who arrive inside the quoted window, jobs completed by the book, and a site left clean when we leave. There’s no fine print hiding a trip charge that appears on the final invoice, and no “manager approval” moment halfway through the job.
Roy Castellanos leads our team, which has been pricing duct cleaning in Miami since 2004. The company has spent two decades building the kind of reputation that makes a written quote mean something. Roy’s operational rule is simple: if we can’t describe the price and scope clearly enough for you to repeat it to a neighbor, we haven’t done our job.
We’re part of the Garrison Partners family, but Hollis Air Duct Miami is independently owned and operated. That means local accountability, local technicians, and local scheduling. The tools we run are professional-grade: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman for Commercial Duct Cleaning. These are the same machines commercial crews use on office buildings and hospitals, not hardware-store equipment.
What the 365-Day Done Right Promise Actually Covers
Every job Hollis completes in Miami is covered by a written 365-Day Done Right Promise. If the work fails within one year, we come back and make it right at no charge. That includes a free second visit. There’s no deductible, no “wear and tear” exclusion, and no negotiation about whether your problem counts. The promise is on paper with every invoice.
This matters in air duct cleaning because of how many operators disappear after a job. You call about a problem three months later, and the number you dialed is disconnected. That can’t happen with a written guarantee. The paper names the company, the date, the scope, and the remedy. If it’s not done right, we’re back at your door.
How to Save on Air Duct Cleaning in Miami
The honest ways to keep your price down are about timing and scope, not chasing a lowball bid that will balloon at the door.
- Bundle services. If your dryer vent and air ducts are both overdue, schedule them together. The dryer vent add-on drops to $75 to $125 when combined with a full cleaning.
- Clean on a regular cadence. A system cleaned every 3 years will cost less per visit than one cleaned once a decade, because the job goes faster and needs fewer passes.
- Change your return filters on schedule. A $15 filter changed every 60 to 90 days is the cheapest duct cleaning you’ll ever buy. Filtration products from Honeywell and Aprilaire that we install and recommend pay for themselves in longer intervals between cleanings.
- Do a vent inventory before you call. Count your supply registers and return grilles. Accurate information gets you an accurate quote over the phone, and an accurate quote means no repricing when the technician counts them.
- Get a written quote before the truck rolls. That’s standard practice at Hollis, not a “special.” A written price protects you from the most common Miami duct cleaning complaint: the quote said $99, the bill said $900.
Here’s the thing about the $99 whole-house duct cleaning offers you’ll see on Miami Facebook groups and postcards. That price covers maybe four vents and one return. Anything beyond that, the technician either skips or charges separately. By the time the real scope is priced, you’re often above what a straight-shooting company would have quoted you in the first place. If the Miami price sounds too low to pay for gas, insurance, trained labor, and professional equipment, it is.
How Long Does Air Duct Cleaning Take in Miami?
A typical single-family home in Miami takes 3 to 6 hours from arrival to final walkthrough. A condo with 6 to 10 vents can be done in 2 to 3 hours. Larger homes in Kendall or Pinecrest with 15-plus vents and two air handlers can run 6 to 8 hours.
The variable is the amount of buildup and the access layout. Attic ductwork in a South Miami ranch with a low-pitch roof is a crawl-space job with limited headroom. A Doral home with a walk-in attic and a single trunk line moves much faster. Either way, we schedule a window and we hit it. The Garrison Code says arrive inside the window, and our technicians are held to that standard on every job.
Is Air Duct Cleaning Worth It in Miami?
For most Miami homeowners, yes. The question is whether you’re paying for cleaning or you’re paying for the appearance of cleaning. A real negative-air and rotary brush job will pull pounds of debris from a system that hasn’t been touched in years. Homeowners we serve across Miami routinely tell us the dust load in the house drops noticeably within the first month, the musty smell from the vents goes away, and the AC cycles less often.
If you’re paying $350 for a thorough clean of a 2,000-square-foot house and you get 3 to 4 years of noticeably cleaner indoor air, that’s $7 to $10 a month. A cheap vacuum pass that leaves half the debris where it was is the one that isn’t worth the money, no matter the price.
Frequently Asked Questions: Air Duct Cleaning Cost in Miami
How much does air duct cleaning cost in Miami in 2026?
Between $350 and $700 for most single-family homes. Condos and smaller townhomes run lower; large houses with multiple air handlers can exceed $900. Call (850) 660-3272 for a written quote based on your square footage and vent count, free.
Is it cheaper to clean air ducts or replace them?
Cleaning is almost always cheaper. Full duct cleaning in Miami runs $350 to $700. Replacing ductwork can run $3,000 to $8,000 depending on home size. Most duct systems are cleanable, not replaceable, unless they’ve been crushed, water-damaged, or are so old the material is degrading. Hollis will show you camera footage of your duct interiors before recommending replacement.
How much does dryer vent cleaning cost in Miami?
Standalone dryer vent cleaning costs $100 to $175. Bundled with air duct cleaning, it drops to $75 to $125. Given that dryers cause thousands of house fires every year, it’s the cheapest fire prevention measure you’ll find. Call (850) 660-3272 and ask about bundling both services during one visit.
Can you clean air ducts the same day?
Yes, in most cases. Hollis Air Duct Miami schedules same-day and next-day appointments throughout Miami-Dade County based on technician availability. Morning slots fill fastest during summer, when AC systems are running hardest. Call (850) 660-3272 early in the day for the best chance of a same-day visit.
Does insurance cover air duct cleaning?
Homeowner’s insurance rarely covers air duct cleaning as a preventive service. Coverage exceptions apply after events like fires, floods, or mold remediation where duct cleaning is prescribed as part of the claim. If you’re cleaning ducts after water intrusion or a smoke event, ask your adjuster whether cleaning is included in the claim before paying out of pocket.
