AfterHow Much Does Air Duct Cleaning Cost in Miami?
Air duct cleaning in Miami, FL typically costs between $285 and $520 for a standard single-family home in 2026, with most homeowners paying around $390 for a full-system cleaning. Homes with larger square footage, multiple AC units, or heavy dust and mold buildup can run $600 to $900 or more. At Hollis Air Duct Miami, we give you a written price before any work starts, so the number you approve is the number you pay.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what we’re seeing across Miami-Dade County this year. These are real ranges pulled from the jobs we quote every week in neighborhoods like Kendall, Hialeah, Coral Gables, and Doral.
| Service | Typical Price Range | What’s Included |
|---|---|---|
| Basic duct cleaning (up to 10 vents) | $250 – $380 | Supply and return ducts, registers, main trunk line |
| Full-system cleaning (11 – 20 vents) | $350 – $520 | All ducts, plenum, blower compartment, registers, return air chase |
| Full-system cleaning (20+ vents or two AC units) | $520 – $850 | Everything above, plus second air handler and extended duct runs |
| Dryer vent cleaning (add-on or standalone) | $89 – $165 | Full lint removal from dryer to exterior termination |
| Duct sealing (per access point) | $95 – $210 | Aeroseal or mastic sealing at joints and connections |
| Sanitizing fog treatment (optional) | $95 – $220 | Antimicrobial fog applied after mechanical cleaning |
Most Miami homes fall into that $350 – $520 band. If a house has never been cleaned and the previous owners had pets, expect the higher end. Newer construction in Doral or Pinecrest with tight, accessible ductwork usually lands at the lower end.
What Affects Air Duct Cleaning Pricing in Miami
No two houses price out the same. Here’s what actually moves the number:
- Number of vents and returns. Every supply register and return grille adds time. A 1,400-square-foot townhouse in Brickell might have 8 vents. A 3,200-square-foot house in Palmetto Bay could have 22. More vents means more hose pulls, more agitation, more labor.
- Number of air handlers. Miami homes with two AC systems, one upstairs and one downstairs, require a second full cleaning cycle. That’s not a small upcharge; it’s essentially cleaning two separate systems.
- Access to the air handler. Attic installations in older Coral Gables or Coconut Grove homes are often tight, hot, and slow to work in. Closet units in newer Kendall construction go faster. Labor time is the single biggest cost driver.
- Duct condition and buildup. We pull before-and-after photos on every job. If the ducts have a quarter inch of gray fuzz and construction debris from a renovation, that’s real time with the rotary brush and negative-air machine. Light dust clears in one pass. Years of neglect doesn’t.
- Mold or moisture issues. Miami’s humidity means we see mold more than most markets. If we find visible microbial growth, we’ll tell you, show you the photo, and quote a sanitizing treatment as a separate line item. We don’t fold it into the base price and we don’t scare you into it.
- Whether the home has flex duct or rigid metal. Older Miami homes often have rigid metal ductwork that stands up to aggressive brushing. Flex duct needs a gentler touch and different tools, which changes the time and sometimes the price.
One thing that should never affect the price: what kind of car is in your driveway. We quote the job, not the customer. That’s part of The Garrison Standard we run on, written pricing before work begins, every time.
How Much Does Air Duct Cleaning Cost by Home Size in Miami?
Square footage is a decent starting point, but vent count matters more. Still, here’s a realistic guide for Miami’s housing stock:
- Condo (under 1,200 sq ft, 4 – 8 vents): $230 – $330. Most Miami condos in Edgewater, Brickell, and Midtown fall here. The duct runs are short, but building access can add a trip charge if the association requires specific entry windows.
- Small single-family home (1,200 – 1,800 sq ft, 8 – 12 vents): $300 – $420. Common in Kendall, Westchester, and Cutler Bay.
- Mid-size home (1,800 – 2,600 sq ft, 12 – 18 vents): $380 – $540. This is the sweet spot for most Miami suburbs like Doral, Fontainebleau, and Country Walk.
- Large home (2,600 – 4,000 sq ft, 18 – 28 vents): $520 – $780. Think Pinecrest, Palmetto Bay, and parts of Coral Gables. Two air handlers become common at this size.
- Estate or multi-zone home (4,000+ sq ft or 3+ AC units): $750 – $1,100+. Custom pricing after an on-site walkthrough.

Is Air Duct Cleaning Worth It in Miami?
In this climate, yes, and more than most places. Miami runs air conditioning 10 to 11 months out of the year, which means your ducts move air constantly. That constant operation pulls in dust, pet dander, and the fine particulate that settles on every surface in a Miami home.
What we pull out of the average duct system in Miami-Dade on a first-time cleaning is consistently worse than what we see in dryer climates. The humidity compounds it. Dust that would stay dry and loose in Phoenix becomes sticky and matted in Miami. It clings to the duct walls and doesn’t break free without mechanical agitation.
Roy Castellanos, who leads Hollis Air Duct Miami, puts it plainly: “In Miami, your ducts are working harder than any other system in the house except maybe your roof. We’ve cleaned systems in Kendall that hadn’t been touched since the house was built in 2002. The amount of material we removed would fill a five-gallon bucket. Twice.”
How Do We Clean Ducts? The Method Matters
You’ll hear a lot of terms thrown around in this trade. Here’s what they mean in plain English and why they affect your price.
Negative-Air Method
This is the industry-standard approach and what we run on every job. A large vacuum unit creates negative pressure in the duct system while we agitate the duct walls with rotary brushes. The dust we dislodge gets pulled directly into the vacuum’s HEPA filtration, not blown into your living room. A Nikro negative-air machine is the backbone of this setup. If a company quotes you without mentioning negative air, ask them how they plan to contain the dust. The answer tells you a lot.
Rotary Brush Systems
We use Rotobrush equipment, which spins stiff nylon or polypropylene brushes through the duct run while compressed air helps lift debris. This matters in Miami because dust here isn’t loose, it’s adhered. You need the mechanical action of a rotating brush to break that film of humidity-glued dust off the duct walls. Vacuum alone won’t do it.
Duct Sealing
After cleaning, we inspect for leaks at the joints and connections. Miami homes lose a measurable amount of conditioned air through unsealed ducts, especially in attic installations where the temperature differential is extreme. Sealing with mastic, a thick paste applied at each joint, closes those gaps. It’s not included in the base cleaning price because not every home needs it, but when we find leaks, we’ll show you photos and give you a written quote before touching anything.
What’s Included in Our Air Duct Cleaning in Miami?
Every Hollis Air Duct cleaning in Miami includes the same scope of work, priced in writing, whether you’re in a Little Haiti cottage or a six-bedroom house in Coral Gables:
- Full cleaning of all supply and return ducts
- Cleaning of the main trunk line and branch runs
- Air handler and blower compartment cleaning
- Removal and cleaning of all registers and grilles
- Return air chase and filter housing cleaning
- Before-and-after photos of the duct interior, every job
- Site left clean. No dust, no debris, no footprint trail.
What we don’t do: quote you a low number to get the appointment, then “discover” problems that double the price. The Garrison Standard we operate under doesn’t allow it. Written price before work begins means written price before work begins.
How Often Should You Clean Air Ducts in Miami?
Every 3 to 5 years is the rule for most Miami homes. Here’s when we’d recommend sooner:
- After a renovation. Drywall dust and construction debris get pulled straight into the return system. We’ve seen ducts in Coconut Grove renovation projects so packed with dust you couldn’t see the metal.
- Moving into a previously owned home. You don’t know what the last family’s lungs left behind. Pet dander, tobacco residue, candles, all of it is in the ducts.
- If anyone in the home has respiratory issues. Asthma, allergies, or COPD. Clean ducts won’t cure anything, but they remove one contributing layer of fine particulate.
- Visible mold or a musty smell coming from the vents. Miami humidity makes this more common here than almost anywhere in the country. Call us and we’ll tell you honestly if what you’re seeing is dust or microbial growth.
How to Save on Air Duct Cleaning
We’re not going to tell you to wait for a coupon. Here’s what actually saves money on duct cleaning in Miami:
- Combine services. If you’re getting your ducts cleaned, adding dryer vent cleaning at the same visit is the cheapest that service will ever be. The crew is already at your home with the equipment staged. It takes maybe 30 more minutes.
- Change your filters before we arrive. A clogged filter means the air handler has been pulling harder. It’s not a price factor for us, but a clean filter after cleaning keeps the ducts clean longer, which means you can stretch the time between cleanings.
- Know your vent count before you call. Count every supply register in the ceiling, floor, or walls. That’s a supply vent. Count the larger grille where the filter sits. That’s the return. Having accurate numbers gets you a tighter phone quote.
- Get the written quote before any work begins. All Hollis quotes are free. Calling (850) 660-3272 and getting a real number takes ten minutes. It costs you nothing.
FAQs – Air Duct Cleaning Cost in Miami
How much does air duct cleaning cost in Miami in 2026?
Most Miami homes pay between $285 and $520 for a full-system cleaning, with an average around $390. Larger homes or dual-AC systems run $520 to $900. Condos in buildings like those in Brickell or Edgewater typically come in at $230 to $330. Call Hollis Air Duct Miami at (850) 660-3272 for a written quote specific to your home, free, no obligation.
Is it cheaper to clean or replace air ducts?
Cleaning is dramatically cheaper. A full cleaning runs $285 to $520 for most homes. Replacing ductwork in Miami runs $3,000 to $8,000 or more depending on accessibility, material, and whether the ducts are in an attic or slab. Replacement only makes sense if the ducts are physically damaged, crushed, or severely rusted. We’ll tell you honestly which situation you’re in before recommending anything.
How long does air duct cleaning take?
Plan on 3 to 5 hours for a typical single-family home in Miami. Condos take 2 to 3 hours. Large homes with two air handlers can take a full day. We arrive inside the quoted window, and when we leave, the ducts are clean and the site is clean. That’s the operational standard.
Does air duct cleaning reduce energy bills?
A clean system moves air easier, which means the blower motor doesn’t work as hard. The savings are real but modest, most Miami homeowners see $5 to $15 per month in peak cooling season after a heavy cleaning. The bigger payoff is air that smells better, less dust settling on furniture, and a system that’s not circulating years of accumulated grime. If your ducts are sealed as part of the service, the efficiency gain is more substantial because you’re no longer losing conditioned air into the attic.
Can I clean my air ducts myself?
Not effectively, and in some Miami homes, not safely. The average duct run in a Miami attic is 15 to 25 feet with bends you can’t reach from the register. Household vacuums don’t generate the negative pressure needed to pull debris from the trunk line, and DIY agitation methods won’t break the film of humidity-glued dust that accumulates here. Professional equipment, like the Nikro negative-air machines and Rotobrush systems we run, exists for this exact job. Attempting it yourself will get the first two feet of duct and leave the rest untouched.
What is the 365-Day Done Right Promise?
Every job we complete in Miami is covered in writing for 365 days. If something we cleaned fails or wasn’t done right, we come back at no charge. That includes a free second visit, no negotiation, no fine print. If the work doesn’t hold up, we make it right. That’s the promise, and it’s on every invoice.
Do you offer free estimates in Miami?
Yes. Every estimate is free, and the price we give you in writing is the price you pay. No door swings, no add-ons unless we find something and you approve a separate written line item. Call (850) 660-3272 and you’ll talk to a live person, not a voicemail.
