Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterHow Much Does Air Duct Cleaning Cost in Miami?
Air duct cleaning in Miami typically costs between $350 and $700 for a standard single-family home with one HVAC system, and most jobs land in the $400 to $550 range. Larger homes with two systems, heavy mold or mildew growth, or more than 15 vents usually run $700 to $1,200. Every job we quote comes with the price in writing before any work starts, so the number you agree to is the number you pay.
If you’ve been calling around Miami and getting “it depends” as an answer, that’s not a real quote. Below is what things actually cost here in 2026, what pushes a job up or down, and how to tell whether you’re being priced fairly or sold something you don’t need. For comparison, see How Much Does Air Duct Cleaning Cost in Nashville-Davidson, TN? (2026 Price Guide).
Key Takeaways
- Standard single-system home: $350-$700, most commonly $400-$550.
- Two-system or larger home: $700-$1,200.
- Dryer vent cleaning, when bundled with duct cleaning: $100-$175 (vs. $150-$250 on its own).
- Mold remediation inside ductwork adds $300-$900 depending on how far it spread.
- Miami’s humidity means ducts here grow biological growth far more often than in dry markets, so this isn’t a “maybe” inspection.
- You should get a written price before anyone starts. That’s not a courtesy. It’s the standard we hold ourselves to on every job.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how pricing breaks down line by line in the Miami market. These are real ranges, not teasers to get someone in the door.
| Service | Typical Miami Price Range | Notes |
|---|---|---|
| Standard air duct cleaning (1 system, up to 10 vents) | $350 – $550 | Includes supply and return lines, registers, and main trunk |
| Full home cleaning (2 systems, 11-20 vents) | $700 – $1,200 | Most common in Kendall, Palmetto Bay, and Doral homes |
| Additional vent beyond 20 | $15 – $30 each | Applies to larger properties |
| Dryer vent cleaning (bundled) | $100 – $175 | Add-on price when done with duct cleaning |
| Dryer vent cleaning (standalone) | $150 – $250 | Higher because of separate trip and setup |
| Mold remediation inside ductwork | $300 – $900 | Depends on square footage affected and severity |
| Air duct repair (sealing, reconnecting, patching) | $250 – $800 | Written guarantee included with every repair |
| HVAC coil cleaning add-on | $150 – $400 | Worth considering if the system hasn’t been serviced in 2+ years |
| Sanitizing / antimicrobial fogging | $100 – $250 | Used after mold treatment or heavy contamination |
Two things push Miami jobs toward the higher end more than anywhere else we work: humidity-driven microbial growth and the sheer size of some of the newer builds out west. Costs in Oakland run differently-see How Much Does Air Duct Cleaning Cost in Oakland, CA? (2026 Price Guide). A 4,000-square-foot home in Kendall with two systems and 22 vents is a different job than an 1,800-square-foot Coral Gables bungalow with one. The equipment time, the number of access points, and the amount of debris removed all change.
Third factor: how long it’s been since the last cleaning. A home that’s never had ducts cleaned since it was built in 2015 will take longer and produce more material than one cleaned three years ago, and that shows up in the labor line.
What Affects Air Duct Cleaning Pricing in Miami
- Number of HVAC systems. A single-system home takes roughly 2-3 hours. Two systems means two full air handlers, two return trunks, and typically double the supply runs. That’s why two-system homes start around $700.
- Vent count. The average Miami home has 10-15 vents. Above 20, expect a per-vent charge. Older Little Havana and Hialeah homes sometimes have fewer vents but tighter ductwork that’s harder to access.
- Humidity-related contamination. This is the big one. Miami’s year-round average humidity sits in the 70-80% range, and that moisture condenses inside ductwork during cool months when the AC runs less. In neighborhoods like Coconut Grove and South Miami, where homes sit under heavy tree canopy and stay shaded, we regularly find microbial growth on interior duct lining that wouldn’t happen in a drier climate. Mold remediation isn’t a scare tactic here, it’s a common finding.
- Duct material and age. Flex duct (common in homes built after 1990) is faster to clean. Rigid metal duct with internal insulation takes longer and requires gentler handling. Fiberboard duct, common in some 1980s construction, needs low-pressure methods so the board doesn’t break down.
- Access. If the air handler is in a tight attic or a second-floor mechanical closet with a foot of clearance, setup takes extra time. Miami homes with flat roofs often have less accessible attic space than homes with pitched roofs.
- Contamination severity. Pet dander, construction dust from a recent remodel, water intrusion after a storm, or visible debris around registers all add labor. A home that flooded during a named storm will need more work than one that didn’t.
We use professional-grade equipment from Rotobrush and Nikro, which pulls debris under negative pressure rather than blowing it around the room. That matters more in Miami than most markets because disturbed mold spores spread fast in high humidity. If someone shows up with a shop vac and a brush, that’s not our Air Duct Cleaning services.
How to Save on Air Duct Cleaning
You don’t need to hunt for the cheapest quote in Miami. You need to avoid paying twice.
- Bundle dryer vent cleaning with duct cleaning. Doing both in one visit saves you the second trip charge, usually $50-$75. Dryer vent lint is also a fire risk, so it’s money well spent.
- Get the price in writing before work starts. This is the single best protection against a $400 quote turning into an $800 invoice. We put the price in writing on every job, no exceptions, and you should expect that from anyone you hire.
- Skip the upsells you don’t need. If your ducts aren’t mold-affected, antimicrobial fogging is optional. Ask what the technician found and whether the add-on addresses a real problem.
- Handle minor repairs during the cleaning visit. If a duct connection is loose or a run is disconnected, fixing it while the equipment is already set up costs less than a separate repair trip.
- Ask about a free second visit if a repair fails. Our written guarantee includes a free return visit if a covered repair doesn’t hold. That saves you from paying twice for the same fix, which is where real money gets lost.
- Time it around AC service. If your HVAC company is already coming out for a tune-up, coordinate the two visits. Less disruption, fewer scheduling gaps.
Free estimates are available any time you call (980) 447-2498, and a live person answers, day or night. No voicemail, no callback queue. If you want to know what your specific home will cost before you commit, that call takes about five minutes.
Is Air Duct Cleaning Worth the Cost in Miami?
For most Miami homeowners, yes, but not on the same schedule as the rest of the country. HVAC trade guidance suggests cleaning every 3-5 years. In South Florida’s climate, we see homes where 3 years is right and homes where 5 is fine, depending on humidity exposure, pets, and whether anyone in the house has allergies or asthma.
Signs that it’s time, regardless of the calendar:
- Visible dust puffing from registers when the AC kicks on
- A musty or damp smell when the system runs
- Allergy symptoms that get worse indoors, not better
- Recent water intrusion, roof leak, or storm flooding
- A recent remodel that put drywall dust into the return
- More than 5 years since the last cleaning
If two or more of those apply, a $400-$550 cleaning is cheaper than a neglected system that shortens the life of a $6,000-$10,000 HVAC replacement. That’s the real math.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Miami?
Air duct cleaning in Miami costs $350-$700 for a standard single-system home, with most jobs landing at $400-$550. Two-system homes and larger properties run $700-$1,200. Homes with mold growth or storm-related water damage can go higher. Call (980) 447-2498 for an exact quote on your home – estimates are free.
Why is air duct cleaning more expensive in Miami than in other cities?
Miami’s humidity drives the price up in two ways: microbial growth inside ductwork is far more common here, and removing it safely takes longer than a standard dust-and-debris cleaning. Jobs that include mold remediation run $300-$900 above a standard cleaning. Homes under heavy tree canopy in Coconut Grove and South Miami see this most often. Call (980) 447-2498 to schedule an inspection and get a written price.
Is it cheaper to repair or replace air ducts?
Repair is almost always cheaper. Sealing a disconnected run, patching a tear, or reconnecting a boot typically costs $250-$800, while full duct replacement can run $3,000-$8,000 or more. If more than about 30% of the duct system is failing, replacement starts to make sense. We’ll tell you which side of that line you’re on before any work begins – call (980) 447-2498 for a free estimate.
Does air duct cleaning really help with allergies in Miami?
Yes, and the effect is usually noticeable within a few days for homeowners with dust or mold sensitivities. Cleaning removes accumulated dander, pollen, and microbial growth that gets recirculated every time the AC runs. In Miami, where the system runs most of the year, that recirculation happens more often than in cooler markets. Call (980) 447-2498 to schedule a cleaning.
How often should Miami homes have their air ducts cleaned?
Every 3-5 years for most Miami homes, and every 2-3 years if you have pets, allergies, or a home that’s had water intrusion. Because the climate keeps moisture in the system longer, the short end of that range is more common here than in drier parts of the country. Call (980) 447-2498 and we’ll give you a straight answer for your specific home.
Can you come today?
Same-day and next-day appointments are often available, and our phone line is answered by a live person 24/7, so you’ll get a real answer when you call. The exact window depends on the day’s schedule. Call (980) 447-2498 and we’ll tell you what’s open.
What Happens If Something Goes Wrong
Every repair we make is covered by a written guarantee, and if a covered repair doesn’t hold, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job. We don’t consider a job finished until it’s working the way it should.
Before any technician arrives at your door, you’ll get their name and photo. They’ll be in a clean, marked uniform, and they’ll show a photo ID badge when you open the door. If you’re home alone, have young kids, or simply don’t like letting strangers in without knowing who they are, this is the part that matters. You’ll know exactly who’s coming before they knock.

What Our Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E.
