Fast, Reliable Air Duct Cleaning Across Miami
Air duct cleaning in Miami typically costs $350 – $650 for a full single-family home system, and most jobs are completed in 4 – 6 hours. The real issue here isn’t just dust. It’s humidity, salt air, and ductwork that has been pulling in moist, corrosive air since before most of our techs were born. If you live in Coral Gables, Brickell, Kendall, or anywhere else in Miami, you’re fighting a climate that turns ordinary duct grime into something biological. We’re Hollis Air Duct Miami, founded in 2004 as part of the Garrison Partners family. Roy Castellanos runs our crews, and every job starts with a written price before any work begins.

Why Hollis Air Duct Miami Is Miami’s Preferred Air Duct Cleaning Company
We do not compete on the lowest teaser price. We compete on written standards. Every Hollis Air Duct Miami technician is background-checked and uniformed. The price is written down before we touch a vent. If the work fails within 365 days, we come back at no charge and make it right. That’s the 365-Day Done Right Promise, and it’s in writing on every job, not implied in a handshake.
Miami’s housing stock demands a local crew. High-rise condos in Edgewater and Brickell require building coordination, access through small closet ceilings, and sometimes permission from property management before we can even set up equipment. Older Coral Gables homes have original galvanized ducts that rusted through years ago. A crew driving in from out of market doesn’t know that. We do, because we work these buildings every week.
Our trucks carry Rotobrush rotary brush systems and HEPA-filtered negative-air machines. We stock filtration products from Honeywell and Guardsman for Miami customers who want better air after the clean. And when you call, a live person answers. No voicemail loop, no callback queue.

HVAC Duct Cleaning in Miami
HVAC Duct Cleaning in Miami means removing the accumulated salt dust, mold, and fibrous debris from every reachable section of your supply and return duct system. For a typical 2,000 sq ft home in Miami, that job runs $350 – $650 depending on the number of returns and the condition of the runs. The work involves negative-pressure extraction at the air handler with a HEPA-filtered vacuum (ours come from Nikro), mechanical agitation inside the ducts with a Rotobrush system, and a camera inspection before and after to verify what actually left the system.
Source Removal, Not Surface Wiping
The way a duct gets clean is by creating negative pressure and brushing debris loose so it’s pulled out, not pushed around. We do not wipe down registers and call it done. In single-family Miami homes, that method leaves behind the salt-and-dust paste that coats duct walls in this climate. Our process removes it.
Air Handler Cleaning and Filter Seating
In Miami, the air handler sits in a closet, attic, or outdoor platform where humidity concentrates. We clean the blower, evaporator-facing surfaces, and the filter housing, and we check that the filter actually seats properly. A loose filter lets dirty air bypass the entire system, which is common in older Miami homes.
Vent Cleaning in Miami
Vent cleaning in Miami usually refers to the supply registers, return grilles, and visible duct openings throughout the home. A supply and return vent cleaning alone runs $150 – $300 and takes about two hours. But in this market, vent cleaning rarely makes sense without cleaning the full connected duct run, because the vent is just the visible end of a long hidden passage filled with accumulated debris.
Supply Registers and Return Grilles
We remove each register, clean the boot behind it, and re-seat it with proper screws or gaskets if the opening has been painted over or warped. In Miami’s humidity, painted-over registers often trap condensation, which turns to rust and drips down the wall. We see it constantly in 1950s and 60s single-family homes in Miami neighborhoods like Shenandoah and Allapattah.
High-Rise Vent Access
Condo vent cleaning in Miami is different. In buildings like those along Brickell Avenue, many registers open into chases shared with neighboring units. We cannot safely agitate those runs without confirming the path is isolated. That’s why we use remote camera verification before and after cleaning, so we know what we reached and what we didn’t.
Trusted Brands We Service in Miami
We work on systems and with equipment from brands Miami homeowners and building managers already trust. That includes air handlers paired with Honeywell filtration, Guardsman filter media, Rotobrush cleaning systems, and Nikro negative-air platforms. Because we service these brands regularly, we know their filter dimensions, access points, and the failure modes common in Miami’s humid, salty air. You don’t need to explain your system to us. We’ve likely already worked on a dozen like it this year. For a deeper look at what a full Air Duct Cleaning job includes, our service hub explains the process step by step.

AfterCommon Air Duct Cleaning Problems We See in Miami Homes
- Mold on register boots and duct interiors. Miami’s year-round humidity keeps duct surfaces damp, especially near supply registers in air-conditioned rooms. By the time you see black spots on a ceiling vent, the duct behind it has been wet for months.
- Rusted-through galvanized duct runs. Original metal ducts in 50s to 70s Miami homes have been exposed to salt air for decades. We regularly find runs rusted through behind walls and in attics, pulling in insulation and attic dust even after a fresh cleaning.
- Crushed or disconnected return ducts. In older Miami homes with slab foundations, return runs under the slab collapse or crack over time. One crushed return can drop total airflow dramatically, and no amount of cleaning will fix it until the run is repaired or replaced.
- Shared riser contamination in high-rise condos. In Brickell and Edgewater buildings, a single unit’s ducts often connect to a shared riser. If a neighbor has had construction dust, pest treatments, or their own duct neglect, it can migrate into your system through gaps in the riser.
Pricing for Air Duct Cleaning in Miami, FL
In Miami, a full system air duct cleaning for a single-family home typically runs $350 – $650. Condo units with shared risers and limited access run $300 – $500 per unit, depending on the number of registers and the access points available. Vent-only cleaning runs $150 – $300. What moves the price is the number of returns, the presence of inaccessible sections requiring camera verification, and whether we find damage that requires sealing work. We give you a written price before any work starts, and that price does not move at the door. Call (850) 660-3272 for a free estimate on your specific system.

FAQs About Air Duct Cleaning in Miami
Because Miami’s humidity and salt air create biological growth inside ducts that Orlando’s drier inland air does not. Condensation forms on duct walls whenever cold AC air meets warm, moist outdoor air, and Miami’s sea breeze adds salt particles that mix with dust into a damp, corrosive paste. An Orlando home might go several years between cleanings without visible mold. In Miami, we see mold regrowth within 12 months if the air handler and blower are not addressed at the same time as the ducts. Call (850) 660-3272 for an exact assessment of your system.
We coordinate with building management, determine which sections of duct are dedicated to your unit versus shared, and use HEPA-filtered negative pressure to prevent cross-contamination during cleaning. Many Miami condo associations require this protocol, and we follow their rules exactly. We also use remote cameras to verify that the runs we could not physically reach were not dislodging debris into shared risers.
It means the galvanized coating on the inside of the duct has failed after decades of salt air exposure, and the metal has rusted through to open holes. Those holes pull attic insulation, salt dust, and humid air into the duct stream, and they let conditioned air leak out. Cleaning alone doesn’t fix a rusted-through run. The holes must be sealed with mastic or the section replaced before the system will stay clean.
Yes. We clean your unit’s dedicated duct runs from inside your own space using negative air pressure and rotary brush agitation. If your risers connect to shared sections, we verify with cameras and coordinate with building management to ensure no debris is pushed into a neighbor’s system. Our HEPA-filtered negative pressure machines meet the standard most Brickell buildings require for exactly this reason.
Salt air corrodes the aluminum fins on the air handler coil and can rust the blower motor housing and wheel over time. The corrosion roughens surfaces, which then hold dust and biological growth more readily. Cleaning the blower wheel and coil removes the debris that adheres to corroded surfaces, and it can restore measurable airflow. It will not reverse the corrosion, but it slows the decline and gives you a clear picture of what’s salvageable. Call (850) 660-3272 for a free estimate.
