Trusted Air Duct Cleaning for Miami Homeowners
Air duct cleaning in Miami means removing the dust, mold spores, and debris that build up inside your ductwork and then recirculate through your home day after day. In a climate where humidity stays above 70% for most of the year, ducts in neighborhoods like Kendall, Coral Gables, and Doral collect more than dust: they collect moisture, which turns into a breeding ground for mildew and allergens. Hollis Air Duct Miami has cleaned thousands of residential and commercial systems across Miami since 2004, and we back every job with our 365-Day Done Right Promise, written into your invoice. Call (850) 660-3272 to schedule a cleaning or simply ask us a straight question about your system.
Air Duct Cleaning Services
Air Duct Cleaning Services cover the full scope of what builds up inside the ductwork that carries conditioned air from your HVAC unit to every room in your house. In Miami, that means dust, pet dander, construction debris from older homes in Little Havana, and the kind of humid-air residue that turns into mold film on duct walls. Hollis Air Duct Miami provides complete air duct cleaning services using negative-air machines from Nikro paired with rotary brush systems from Rotobrush, which loosen and extract debris rather than just pushing it around. A Full System Cleaning for a typical Miami home runs between $350 and $700 depending on the number of returns, the length of the duct runs, and how long it has been since the last cleaning. Every quote is written down before any work begins, and it does not move at the door.
Full-System Extraction
We connect a Nikro negative-air machine to your ductwork to create continuous suction throughout the entire system. Then we run a Rotobrush rotary brush through each supply and return line to dislodge caked-on dust and debris. The extraction pulls it all into a HEPA-filtered containment unit, not back into your living room.
Supply and Return Line Clearing
Miami homes with central AC often have returns pulling air from shared hallway spaces, which means they collect more traffic dust than systems in cooler climates. We clear both supply and return lines completely, including the boots behind each register. That is where the bulk of the debris usually sits, and it is the part most one-truck outfits skip.

Styles & brands we work with
HVAC Duct Cleaning
HVAC Duct Cleaning refers specifically to cleaning the ductwork that is part of your heating and cooling system, not the dryer vent or the bathroom exhaust. In Miami, where air conditioning runs nearly year-round, the HVAC ducts move more cubic feet of air per year than systems in almost any other U.S. city, which means they collect proportionally more of whatever is in your air. Hollis Air Duct Miami cleans HVAC ductwork as a distinct service with a defined scope: every supply register, every return, the main trunk lines, the plenums, and the blower compartment on the air handler. Pricing for HVAC duct cleaning in a single-family Miami home typically falls between $350 and $650, with larger homes in areas like Pinecrest or Palmetto Bay running toward the top of that range. The price is written before we start, and it is the price you pay.
Air Handler Compartment Cleaning
The blower wheel and housing inside your air handler collect a layer of grime that reduces airflow and forces your system to run longer. We remove the access panel, clean the blower assembly, and wipe down the interior surfaces of the handler. That step is included in our standard HVAC duct cleaning, not billed as an add-on.
Plenum and Trunk Line Decontamination
The plenum is the metal box that sits directly above your air handler, and it is often the dirtiest part of the entire system because all return air passes through it. We open the plenum, clean both the supply and return sides, and inspect the evaporator coil for dust loading. A dirty coil costs you money every month in lost efficiency.
Vent Cleaning
Vent Cleaning addresses the visible parts of your system: the registers and grilles mounted in your floors, walls, or ceilings, along with the boots and the first few feet of duct behind them. Many Miami homeowners call us because they can see dust built up on the register slats or dark streaks on the wall above a vent, and they want it gone. Hollis Air Duct Miami includes thorough vent cleaning in every whole-system job, and we also offer it as a standalone service for homeowners who recently completed renovations, which are common in neighborhoods like Shenandoah and Buena Vista. Standalone vent cleaning for a typical Miami home runs between $150 and $300 depending on the number of registers. You get the entire register, boot, and visible duct opening cleaned, not just the slats wiped down.
Register and Grille Deep Clean
We remove every register from its opening and clean both sides with a degreasing solution that cuts the film that plain dusting leaves behind. Built-up grime on registers is one of the first places mold starts in a humid climate. Clean registers mean the air moving past them is not picking up contamination on the way out.
Boot and Duct Opening Cleaning
The boot is the transition piece that connects the register to the duct run, and it collects a ring of packed dust where air velocity drops. We clean each boot down to the main duct line using a powered whip or brush attachment. That gives you the full benefit of the cleaning instead of just the cosmetic part.
Air Duct Repair
Air Duct Repair covers the physical damage that most Miami homes have somewhere in their duct system: separated joints, crushed flex runs, torn outer liners, or ducts that were poorly installed years ago and have been leaking ever since. In South Florida, where air handlers are often installed in attics that hit 120 degrees in July, flex duct degrades faster than in any northern climate, and duct tape applied by a previous homeowner or a careless contractor fails within a season or two. Hollis Air Duct Miami performs air duct repair using mastic sealant and mechanical fasteners, the same methods specified by the Florida Building Code, and we document every repair with before-and-after photos. Repair pricing depends on what we find during inspection, but most single-duct repairs in Miami run between $75 and $250 per joint or section. You approve the written price before we touch anything.
Leaking Joint and Seam Sealing
Duct joints are where sections of duct connect, and they are the most common leak point on every system. We seal seams with water-based mastic, which is flexible enough to handle the expansion and contraction of Miami’s hot attic conditions. A sealed joint can improve airflow to the farthest rooms by 15% or more, which you notice as a room that finally cools properly.
Crushed or Damaged Flex Duct Replacement
Flex duct gets crushed when someone steps on it in a tight attic, when it gets tied down too aggressively, or when it simply sags over years of heat. We replace damaged sections with new R-8 insulated flex rated for South Florida conditions. You get a written price per section before replacement begins, and the work is covered by our 365-Day Done Right Promise.
Ductwork Cleaning
Ductwork Cleaning is the broadest version of the service: it covers the entire network of ducts, plenums, and fittings that distribute air through your Miami home, including the hard-pipe trunk lines, the flex run-outs to each room, and every surface in between. The difference between “vent cleaning” and “ductwork cleaning” is depth: vent cleaning addresses what you can see, while ductwork cleaning addresses what you breathe. Hollis Air Duct Miami performs ductwork cleaning with professional-grade equipment from Rotobrush and Nikro, not the kind of hardware-store vacuum attachment that gives the whole industry a bad name. Complete ductwork cleaning for a standard three-bedroom Miami home runs between $400 and $750 depending on system size and accessibility. We provide a written line-item price for the whole job before anyone starts.
Main Trunk Line Cleaning
The trunk line is the large duct that runs the length of your attic or crawlspace, with branch lines tapping off it to each room. It accumulates years of dust because it is the highest-volume pathway in the system. We clean the entire trunk with a powered brush system and negative-air extraction running simultaneously.
Branch Run Cleaning
Branch runs are the smaller ducts that connect the trunk line to each register, and they are often the dirtiest because air slows down as it approaches the register. We clean every branch run on the system, not a representative sample. Rooms at the end of long runs get as much attention as the ones closest to the air handler.
Air Duct Inspection
Air Duct Inspection is what we do before we quote a cleaning, after a water event, or any time a Miami homeowner wants to know exactly what is inside their ductwork before committing to anything. We send a camera scope through the main trunk and representative branch runs, and we show you the footage on a tablet while we talk through what we are seeing. That means you are not taking our word for it: you are looking at the inside of your own ducts. A standalone air duct inspection with camera documentation in Miami costs between $150 and $250, and that fee is credited toward the cleaning if you book the work within 30 days. If we find nothing that needs cleaning, we tell you that plainly and leave.
Camera Scope Documentation
Our inspection camera feeds live video to a screen so you can watch the interior of your ducts in real time. We document findings with still images you can keep. No other step gives you as clear a picture of what is actually in there, whether that is routine dust, construction debris, or mold growth that needs a different kind of remediation.
Written Condition Report
After the inspection, you get a written report that documents the type of ductwork, its general condition, any leaks or damage we identified, and our recommendation. The recommendation can include a flat-price quote for cleaning or repair on the same page. You take your time deciding; we do not push for a signature in the driveway.
Residential Air Duct Cleaning
Residential Duct Cleaning is the core of what we do in Miami: cleaning the systems inside single-family homes, condos, townhomes, and apartments so the air your family breathes is moving through clean ductwork. Homes in Miami collect more dust indoors than people expect, partly because windows stay shut through the long summer and partly because construction is constant in growing neighborhoods like Doral and Aventura. Hollis Air Duct Miami approaches residential work with the same protocol every time: written quote, arrival inside the scheduled window, uniformed and background-checked technicians, full cleaning by the book, and a clean site when we leave. A standard residential cleaning in a Miami home runs from $350 to $700, depending on the number of units your home has and how many returns the system pulls from. We recommend having your air ducts cleaned in Miami every two to three years, more often if you have pets, have recently renovated, or live near active construction.
Condos and High-Rise Units
Condominium air systems in Miami present a specific problem: shared chases and building-wide returns mean your ductwork can pick up debris from adjacent units or common areas. We clean condo systems thoroughly, including the individual fan coil or air handler in your unit. Our technicians are experienced working inside the access constraints common in buildings like those along Brickell and Edgewater, and we leave the building’s common areas exactly as we found them.
Homes with Pets
Pet dander and hair move through the return side of your system and deposit on coil surfaces, blower wheels, and duct walls. Homes with dogs or cats in Miami, where doors and windows stay closed most of the year, usually need cleaning on the shorter end of the recommended range. We remove the dander and hair with powered agitation and HEPA extraction, which is the only reliable method for fine particulates.
Commercial Air Duct Cleaning
Commercial Duct Cleaning applies the same standard we use in homes to offices, retail spaces, medical suites, restaurants, and light industrial facilities across Miami. Commercial systems run longer hours, move more air, and often serve more people per square foot than residential systems, which means the consequences of dirty ductwork are multiplied. Hollis Air Duct Miami handles commercial projects with the same written pricing structure and the same 365-Day Done Right Promise we offer homeowners. Commercial pricing is quoted per project based on system size, access, and whether the work needs to happen after hours or on weekends, which many Miami business owners require. A small retail or office space might run from $800 to $1,800, while larger facilities are quoted after a walkthrough and an air duct inspection.
Offices and Retail Spaces
Office HVAC systems in Miami accumulate constant dust from foot traffic, paper products, and outdoor particulates tracked through entryways. We clean commercial ductwork on a schedule that works for your business, including night and weekend service, so we never disrupt your operation. Written scheduling, written pricing, and a crew that shows up in uniform is what you get on every commercial job.
Restaurants and Food Service
Kitchen exhaust and make-up air systems create a heavier grease and particulate load than standard commercial HVAC, which demands a more aggressive cleaning approach and more frequent service intervals. We clean ductwork serving dining rooms and food prep spaces to reduce grease residue and keep air systems compliant with local health expectations. Our negative-air extraction keeps contaminants contained while we work, so your kitchen stays operational.

AfterBrands We Service
We work on duct systems paired with all major HVAC equipment brands, and we know the specific quirks that come with each. Nikro and Rotobrush are the brands we run on the cleaning side: our negative-air machines from Nikro maintain continuous extraction, and our Rotobrush rotary brush systems provide the powered agitation that loose-brush methods cannot match. If you see those names in our truck, that is what they mean: commercial-grade cleaning equipment, not hardware-store kits.
On the filtration side, we service and recommend products from Honeywell, Aprilaire, and Guardsman. A Honeywell media filter cabinet installed on a Miami system does a real job, but only if the air moving through it has already been cleaned at the duct level. An Aprilaire whole-home purifier hooked to dirty ductwork is a waste of your money, and we will tell you that before we sell you anything. Whether you have a Guardsman UV system already installed or any other make, we can clean and service the full assembly.
Signs You Need a Pro Right Now
- Dust returns within days of cleaning your house. If surfaces in your Miami home are coated again within a week, the dust is not coming from the floor or the furniture. It is being pushed out of your registers every time the blower runs. That means the source is inside the ductwork, and no amount of surface cleaning will fix it.
- Visible mold or mildew growth around register openings. Dark staining around your vents in Miami’s humidity is usually mold growth where cool duct surfaces meet warm, moist indoor air. That growth can release spores into the air your family breathes. Get it inspected before it spreads into the ducts.
- You renovate or have work done inside the home. Drywall dust, sawdust, and construction debris get pulled into the return side of your system during any renovation, then blown back out for months afterward. In Miami neighborhoods where remodels are constant, like Coconut Grove and the Roads, post-renovation duct cleaning should be standard practice.
- Your energy bill rises with no change in habits. A thick layer of dust on the evaporator coil or a clogged blower wheel forces your system to run longer to hit the set temperature. Miami’s summer rates make that an expensive problem quickly. Cleaning the ducts and the air handler restores some lost efficiency.
- You have never had the ducts cleaned. If your Miami home is more than five years old and the ducts have never been cleaned, you can assume there is a significant debris load inside them. Marine-layer dust, construction particulates, and humid-air residue all accumulate year over year. The first cleaning is almost always the most dramatic difference.
Our Process, Step by Step
- 1
Written Quote Before Work Begins. We inspect your system and write down a firm price for the entire job, line by line. That price does not change at the door. You know exactly what you are approving before any equipment comes off the truck.
- 2
System Setup and Protection. We lay down floor protection from the entry to the work area, and we set up the Nikro negative-air machine at a main return or plenum opening. The continuous extraction creates negative pressure so debris loosened during cleaning is pulled out of the system, not blown into your rooms.
- 3
Powered Agitation Through Every Run. We run the Rotobrush rotary brush system through every supply and return line in your home, including branch runs that some companies skip. The rotating brush head scrubs the duct walls while the vacuum pulls the loosened material out through the filtration unit.
- 4
Plenum, Coil, and Blower Cleaning. We open the plenum boxes on both the supply and return sides, vacuum them out, and inspect the evaporator coil and blower assembly. If they are carrying a dust load, we clean them as part of the job, not as a separate bill. This is the step that separates a superficial cleaning from a real one.
- 5
Final Walkthrough and Documentation. We walk your home with you, show you before-and-after photos of the system, and reset every register to where it was. The site is left clean, the price matches the written quote, and the work is covered by the 365-Day Done Right Promise in writing.
How Much Does Air Duct Cleaning Cost in Miami?
A full air duct cleaning for a typical single-family Miami home runs $350 to $700. Smaller condos and apartments usually fall in the $300 to $450 range, while larger homes with multiple systems in areas like Pinecrest, Palmetto Bay, or Coral Gables commonly run $500 to $800 or more depending on the number of returns. Commercial spaces are quoted per project. What moves the price is the number of supply and return registers, the linear feet of ductwork, the accessibility of the attic or closet where the air handler sits, and the level of contamination present. A system that has not been cleaned in 10 years takes longer than one cleaned 3 years ago, and the quote reflects that in labor hours.
The best way to avoid overpaying in Miami is simple: demand a written line-item price before the work starts. Any company that quotes you a “per vent” price and then discovers “extra vents” once they are inside is working a bait-and-switch model. We give one flat price per system, not per vent, and it is written before the first register is pulled.

Frequently Asked Questions About Air Duct Cleaning in Miami
Air duct cleaning is the process of removing accumulated dust, debris, pet dander, and microbial growth from the interior surfaces of your HVAC ductwork, including the supply and return lines, plenums, registers, and the air handler itself. In Miami’s humid climate, duct cleaning is especially important because moisture promotes mold film and mildew growth inside ducts, which then circulates through your home. Hollis Air Duct Miami uses negative-air extraction from Nikro and powered agitation from Rotobrush to clean the full system, not just the visible register openings. A complete cleaning handles the entire network of ducts carrying conditioned air in your home.
For a typical single-family Miami home, a complete air duct cleaning takes between 3 and 5 hours from truck arrival to final walkthrough. Larger homes with multiple systems or heavily contaminated ductwork in older neighborhoods like Shenandoah or Coral Way can take 6 hours or more. We give you a clear time window before the job begins, and we arrive inside that window, not outside it. The job is done in a single visit.
Most Miami homes pay between $350 and $700 for a complete air duct cleaning, depending on the number of registers, the size of the system, and the level of contamination. Condos and smaller apartments generally run $300 to $450, while larger homes with multiple units or severely neglected ductwork can run $500 to $800. You get a written, line-item price before any work begins, and that price does not move at the door. Call (850) 660-3272 for a free estimate with a firm written number.
Yes. We service and clean complete systems that include filtration products from Honeywell, Aprilaire, and Guardsman, including media filter cabinets, electronic air cleaners, and UV purifiers. Those systems work properly only when the air moving through them has already been cleaned at the duct level, which is why we address the full path from return to register. If you have a specific model, mention it when you call and we will tell you exactly what we can do with it.
We handle urgent air quality situations in Miami, including post-water-event inspections, visible mold around registers, or systems blowing debris into a home. Our phones are answered by a live person 24 hours a day, 7 days a week, so you will always reach a human being, not a voicemail queue. If the problem requires a same-day or next-day inspection, we will tell you directly where we stand on dispatch availability. Call (850) 660-3272 and describe what you are seeing.
Every job we perform is covered by the 365-Day Done Right Promise, written onto your invoice. If you find a problem with the work within one full year, we return and make it right at no charge, including a free second visit. That covers dirt recurrence at the register level, missed runs, or any issue tied to the cleaning itself. You do not have to negotiate anything, because it is already in writing.
There is not much you need to do before our arrival. Clear a path to the air handler so our technicians can access it, and move any furniture that blocks registers so we can reach every boot. If you have pets, securing them during the visit helps the crew work faster. We handle everything else, from floor protection to final cleanup, and we will call or text when we are on the way.
