Residential Duct Cleaning in Miami, FL

Residential Duct Cleaning in Miami, FL

Air Duct Cleaning in Miami typically costs between $350 and $750 for a full single-family home, depending on square footage, the number of vents, and how long it’s been since the last cleaning. Most jobs take 3 to 6 hours and can be scheduled within the same week. At Hollis Air Duct Miami, we run a negative-air system that pulls debris out of your ductwork rather than blowing it through your living space, and every job comes with a written price before we start and our 365-Day Done Right Promise in writing.

If your home still has its original ductwork from a 1990s or early 2000s build, or you’ve remodeled recently and drywall dust got pulled into the returns, this is the service you’re looking at. You can read more about how it fits into the broader scope of Air Duct Cleaning in Miami on our main service page, or call (850) 660-3272 and talk to a live person about your house specifically.

We’ve been doing this since 2004, and Roy Castellanos runs the Miami location under The Garrison Standard. That standard is not a slogan. It means we arrive inside the quoted window, the price is on paper before we touch a single vent, the crew is background-checked and uniformed, and the site is left clean when we leave. Those are operational rules, not adjectives.

When You Need Residential Duct Cleaning

Ductwork does not fail loudly. It accumulates. The signs are usually slow and easy to dismiss until you notice more than one of them at the same time. Here is what pushes Miami homeowners to call us most often:

• Dust returns to surfaces within a day or two of cleaning. If you can wipe a shelf clean and see a film back by the weekend, the ducts are likely recirculating particulate every time the AC cycles.
• Your AC runs longer than it used to to hold the same thermostat setting. Restricted airflow from built-up debris on the blower and evaporator coil makes the system work harder, and Miami summers already push units hard enough.
• You notice a musty or stale smell when the system kicks on but the odor fades after a few minutes. That pattern usually points to microbial growth or accumulated organic debris inside the plenum or trunk lines, common in Miami’s humidity.
• Renovation work happened recently. Drywall dust, sawdust, tile grout fines, and paint overspray get pulled into return ducts and then redistributed through every room for months.
• A new pet joined the household or someone in the home has unexplained allergy symptoms that improve when they leave the house for a few days.
• You bought the house and have no record that the ducts were ever cleaned. In South Florida, where AC runs practically year-round, we recommend checking the system at least once and then cleaning every 3 to 5 years after that, more often if you have pets or recent construction.

If any two of those sound familiar, a cleaning is probably overdue. And if the system has never been cleaned and the home is older than 15 years, the amount of material we pull out on the first pass tends to surprise people.

Our Residential Duct Cleaning Process

We do not bring a shop vac and call it duct cleaning. We use negative-air extraction, the same method commercial buildings rely on, paired with rotary brush agitation and Return Duct Cleaning where the duct layout allows it. Here is the sequence, in order, every time:

1. Site walk and written quote. Roy or one of our lead techs walks the home, counts vents and returns, checks the plenum access, and writes the total price on paper. That number does not move once the work starts. If we find something unexpected, we stop and show you before any additional charge is discussed.
2. System inspection and protection. We set drop cloths around each register, cover your flooring with corner guards where needed, and inspect the blower, coil, and return cavity for visible mold, pest activity, or debris that would change the scope.
3. Negative-air setup. A Nikro negative-air machine is connected to the duct system to create continuous suction. This puts the ducts under negative pressure so anything we dislodge gets pulled toward the containment unit, not pushed into your living room.
4. Rotary brush agitation of the supply and return trunks. We run a Rotobrush rotary brush system through the main trunk lines and each branch run to mechanically scrub the duct walls. A rotating brush knocks loose the film and debris that suction alone will not remove, especially in older metal or flex duct.
5. Register and grille cleaning. Every supply register and return grille comes off, gets cleaned, and goes back on. These are the surfaces you actually see, and they collect a layer of dust and cooking grease that a duct-only clean would leave behind.
6. Post-clean airflow check and site cleanup. We verify static pressure and airflow at the returns before we pack up, then vacuum any debris around the work area and leave the house the way we found it. Written summary of what was done, what was found, and the date for the next recommended service goes with you.

For homes with excessive humidity or visible microbial growth in the plenum, we discuss a Guardsman antimicrobial treatment or a duct sealing pass as a separate line item. Nothing gets added without your approval and a written price.

Residential Duct Cleaning Pricing in Miami

Miami pricing runs a little higher than national averages because most homes here have larger AC systems and longer runtimes, plus crawl-access or attic installations that affect labor time. Here is what we quote on a typical job:

Home Size	Vents / Returns	Typical Price Range
Up to 1,500 sq ft condo or townhome	6-10 vents	$350 – $450
1,500 – 2,500 sq ft single-family	10-16 vents	$450 – $600
2,500 – 3,500 sq ft single-family	16-22 vents	$600 – $750
3,500+ sq ft or multiple AC systems	22+ vents	$750 – $1,100

These are real ranges we quote from, not teaser numbers. What moves the price on any given house:

• Number of vents and returns, which is a better predictor than square footage alone.
• Access difficulty. Attic units in Coral Gables or Coconut Grove with low-slope roofs take longer than garage-mounted air handlers in Kendall. Crawlspace-only access in older Miami Shores or Shenandoah homes also adds time.
• Condition of the system. If the coils are matted with pet hair or the returns are packed with construction debris, the job takes longer. We quote for what we can see during the walk-through, and we show you photos of anything we find.
• Optional treatments. Antimicrobial application with Guardsman, duct sealing with mastic, or a filter upgrade to a Honeywell or Aprilaire media cabinet are separate line items with their own written prices.

Every quote is free and written down before you commit to anything. Call (850) 660-3272, tell us the rough square footage and how many vents you have, and we will give you an honest range over the phone. If you want an exact number, we schedule a walk-through and put it on paper on the spot.

Why Miami Homes Need Duct Cleaning More Often Than You’d Think

Miami’s climate works against ductwork in ways that don’t apply to a house in Ohio or Colorado. A few specifics worth knowing:

• Humidity and microbial growth. Duct interiors in Miami regularly see relative humidity above 70% during the summer. That is exactly the environment where mold and mildew establish on the dust film inside return ducts and plenums. Cleaning removes the organic material those organisms feed on. It is not a substitute for dehumidification, but it removes the food source.
• Year-round AC runtime. In most of the country, ducts get a winter break. In Miami, the AC can cycle 10+ months a year, sometimes 8+ hours a day from May through October. More runtime means more air moving through the system, which means more particulate accumulation per month than a northern system sees in a year. The 3-5 year cleaning interval we recommend is based on that runtime, not a national brochure number.
• Coastal salt air and metal duct corrosion. Homes within a few miles of Biscayne Bay or the ocean see accelerated corrosion on exposed metal duct components. We regularly see rust scaling inside return plenums in Brickell, Edgewater, and Key Biscayne homes. That scale breaks loose and ends up in the airstream, and a rotary brush pass removes a significant amount of it.
• Construction density. Miami has been in a near-constant building boom for the last two decades. Even if you never remodeled, the drywall dust from a neighbor’s project, or road construction particulate, or the fine silt that blows off demolition sites gets pulled into the returns. Homes in Westchester, Doral, and the areas around the Brightline corridor see this more than most.

None of this is alarmism. It is what our techs see when they pull the return grille off a house that has not been cleaned in 10 years. The first pass with a negative-air system pulls out what most people would describe as a small pillowcase worth of gray-brown material, which is why we also offer Video Inspection so you can see the condition firsthand. You breathe the air that moves through that every single day.

Equipment We Run, and Why It Matters

We do not use hardware-store gear. Here is what that means in plain terms:

• Nikro negative-air machines create continuous suction at the ductwork level so debris is contained and collected, not recirculated into the room. This is the same principle hospital and commercial crews use for contamination control. For your house, it means we are not blowing dust around and calling it cleaning.
• Rotobrush rotary brush systems use a flexible spinning shaft to scrub the inside walls of your ducts. Suction alone will not remove the film that clings to duct surfaces, especially in Miami where humidity makes that film sticky. Mechanical agitation plus negative air is the difference between “vacuum around the edges” and an actual clean.
• Guardsman antimicrobial treatments are used when we find visible microbial growth or when a homeowner in a high-humidity area wants the added protection. It is applied after the mechanical clean and quoted separately in writing.

What the 365-Day Done Right Promise Actually Covers

Trade talk, stripped down: our warranty is one year, in writing, and it says exactly what happens if something goes wrong.

• If the cleaning fails within 365 days, meaning we missed a section, debris re-appears in the ducts that should have been removed, or a register was left loose, we come back at no charge.
• The return visit is free. Not discounted, not prorated, not conditional on buying something else. Free. It is written into the job paperwork.
• The price you sign is the price you pay. No discovery fee, no fuel surcharge, no “we found additional buildup” upsell once we are inside. If we find something that changes the scope, we show you photos, explain it, and get your signature before any additional work is discussed.
• Every tech on the job is background-checked and uniformed. You know who is walking into your home before they arrive, and we tell you the tech’s name when we confirm the appointment.

Roy Castellanos runs this location on that standard because he spent years watching customers get burned by no-shows and moving prices. The Garrison Code, which every tech at this location works under, requires the crew to arrive inside the window, wear the uniform, respect the home, answer questions directly, and leave the job site cleaner than they found it. If a tech fails any part of that, Roy wants the phone call.

FAQs – Residential Duct Cleaning

How much does residential duct cleaning cost in Miami?

Residential duct cleaning in Miami runs $350 to $750 for most single-family homes, and $350 to $450 for condos and townhomes under 1,500 square feet. Larger homes with multiple AC systems can run $750 to $1,100. The biggest price drivers are vent count, access difficulty, system condition, and whether you need Supply Duct Cleaning for multiple zones. Call (850) 660-3272 for a written quote specific to your house, free of charge.

How long does residential duct cleaning take?

Most single-family homes in Miami take between 3 and 6 hours from arrival to final walkthrough. Condos and smaller townhomes are usually done in 2 to 4 hours. If your system has significant buildup, multiple AC units, or difficult attic access, we will tell you before scheduling so you can plan the day. We arrive inside the quoted window, and the price is written before work begins.

Is residential duct cleaning worth it in Miami?

Yes, and Miami’s climate makes it more justified here than in most of the country. Year-round AC runtime, high humidity, and constant construction dust mean duct systems in Miami accumulate debris faster than systems in drier, cooler climates. If you have never had your ducts cleaned and the home is more than 10 years old, the first clean typically removes significant material. We show you before-and-after photos so you can see what you paid for, not just hear about it.

How often should I have my ducts cleaned in Miami?

For most Miami homes, we recommend every 3 to 5 years. Homes with multiple pets, recent renovations, or a household member with significant allergies should consider every 2 to 3 years. Coastal homes within a few miles of Biscayne Bay or the ocean may need more frequent maintenance due to salt air corrosion on older metal ducts. After your first cleaning, our tech will give you a written recommendation for your specific home based on what we found, not a generic schedule.

Do you clean the dryer vent at the same time?

We offer dryer vent cleaning as a separate service and can often schedule it the same day as your residential duct cleaning. The dryer vent is a separate run from the AC duct system, and we quote it as its own line item with its own written price. If you want both done, tell us when you call and we will build the quote accordingly.

Is it cheaper to clean my ducts myself?

You can buy a brush kit at a hardware store for under $100, but a brush kit cannot create the negative-air pressure that actually contains and removes debris from the full system. Without negative air, you are dislodging debris and hoping it gets caught somewhere before it re-enters your living space. The equipment we run, a Nikro negative-air machine paired with a Rotobrush rotary brush, is the same category of equipment commercial buildings require for contamination control. The cost difference buys you containment, actual removal, and a written guarantee.
