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.

AfterFast, Reliable Air Duct Cleaning Across Miami Gardens
Air duct cleaning in Miami Gardens typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. Our crews are dispatched from our Miami office and cover all of Miami Gardens, from the neighborhoods around Hard Rock Stadium to the residential blocks near Carol City and Norland, usually arriving inside a two-hour window.
We’ve been working in Miami Gardens long enough to know what we’re walking into: a 1960s CBS home with the air handler stuffed in a garage closet, original flex duct in a low attic that’s seen forty years of heat, and a family that’s been running the AC nonstop since March. That specific combination, repeated across thousands of homes in this city, is why we don’t treat Miami Gardens like every other South Florida market. Call (361) 326-5060 for a free written estimate.

HVAC Duct Cleaning in Miami Gardens
HVAC Duct Cleaning in Miami Gardens means addressing a system that runs nearly every day of the year, pulling humid outdoor air through ductwork that may have been installed when the house was built in 1967. The job involves source removal: we seal the supply and return plenums, apply negative pressure with HEPA filtration, and use rotary agitation tools to dislodge debris from the full length of each run. A typical residential HVAC duct cleaning in Miami Gardens runs $350 – $550 for a single-system home, with larger homes or dual-zone systems reaching $650.
Negative-Air Method with HEPA Containment
We connect a Nikro negative-air machine to your trunk line, creating suction that pulls dislodged debris through the system and traps it in HEPA filtration before it re-enters your home. In Miami Gardens’s year-round humidity, this matters: without contained extraction, disturbed mold spores and coral-rock dust simply resettle in the ducts or blow back into the living space.
Camera Inspection Before and After
Our Rotobrush video inspection lets you see what we’re seeing: crushed flex runs, disconnected sections, or the fine layer of coral-rock dust that still coats ducts in older CBS homes. The after footage shows the difference source removal makes, not just a surface wipe.
Vent Cleaning in Miami Gardens
Vent Cleaning in Miami Gardens is often what homeowners notice first: dark buildup around supply registers, reduced airflow from certain rooms, or a musty smell when the AC kicks on. But the visible vent is only the endpoint. Real vent cleaning here means tracing the problem back through the duct run to the plenum, because in these older homes the issue is rarely the register itself. A standalone vent cleaning service in Miami Gardens typically runs $150 – $250 if we’re already on site for full system work, or $200 – $350 as a targeted service for isolated problem areas.
Supply vs. Return Vent Assessment
Supply vents push conditioned air into your rooms; return vents pull it back. In Miami Gardens’s 1970s-era homes with short return plenums in garage closets, we often find return vents pulling unfiltered attic or garage air through gaps in the plenum seal. Cleaning the vent without sealing the plenum is temporary at best.
Register Removal and Deep Cleaning
We remove each register, clean the boot and adjacent duct section with contact agitation tools, and treat for mold or mildew if the humidity has caused biological growth. The registers go back sealed and aligned, not forced into stripped screw holes.
Trusted Brands We Service in Miami Gardens
Our equipment roster includes Rotobrush rotary brush systems for contact agitation, Nikro negative-air machines for contained debris extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common replacement components for Miami Gardens homes, including register boots, flex duct connectors, and mastic sealant for plenum repairs. That means when we find a disconnected run or a crushed section in your attic, we can often address it during the same visit rather than scheduling a return trip. For homeowners near the commercial corridors along NW 27th Avenue or in the residential blocks between NW 183rd and NW 207th Streets, that local parts availability translates to faster completion and fewer interruptions to your cooling schedule.
Common Air Duct Cleaning Problems We See in Miami Gardens Homes
- Crushed or disconnected flex duct in low attics. The 1960s – 1980s CBS homes that dominate Miami Gardens have flex duct runs tucked under shallow rooflines where decades of heat cycling and rodent activity compress or separate the material. A surface vacuum of the registers won’t catch a supply run that’s dumping attic air into your bedroom.
- Coral-rock construction dust still coating original ductwork. Miami Gardens was built on coral rock fill, and the fine dust generated during original construction often remains in ducts that have never been properly opened. Every time your AC cycles, that dust re-entrains into your living space.
- Mold and mildew from year-round humidity with no drying season. Without a heating period to drop indoor humidity, evaporator coils and duct interiors stay wet. We frequently find mold speckling around registers in homes where the air handler runs constantly but the ductwork was never designed for moisture management.
- Poorly sealed return plenums pulling unconditioned air. The common garage-closet or hallway-closet air handler installation in Miami Gardens homes often has a return plenum with gaps or missing sealant. Your system pulls hot, humid garage or attic air straight into the return side, overworking the AC and circulating contaminants.
Pricing for Air Duct Cleaning in Miami Gardens, FL
A typical full-system residential duct cleaning in Miami Gardens runs $350 – $650, depending on system size, accessibility, and condition. Single-zone homes with straightforward attic access fall at the lower end; homes with dual AC systems, crushed duct runs requiring repair, or significant mold remediation needs fall at the higher end. Commercial duct cleaning for small retail or office spaces in Miami Gardens typically starts at $800 and scales with linear footage of ductwork.
We do not quote per-vent pricing. That model invites bait-and-switch: a low teaser rate that balloons once the technician is inside your home. Hollis provides one flat price per system, agreed in writing before any work starts. The price does not move at the door. Free estimates are available by phone or in person, and we encourage you to compare our written quote against any competitor’s.
Factors that affect your specific price: the number of AC zones, whether the ductwork is accessible or buried in a slab, the presence of mold or biological growth requiring antimicrobial treatment, and whether we find disconnected or crushed runs that need repair to restore proper airflow. Call (361) 326-5060 for an exact quote for your Miami Gardens home.

FAQs About Air Duct Cleaning in Miami Gardens
Every 3 – 5 years for original ductwork in these homes, and sooner if you notice reduced airflow, musty odors, or visible mold around registers. The coral-rock dust from original construction and the year-round humidity mean these systems accumulate debris faster than ducts in newer construction or drier climates. Call (361) 326-5060 to schedule an inspection and we’ll tell you where your specific system stands.
Yes. Miami Gardens’s concentration of 1960s – 1980s CBS homes with original flex duct, low attic access, and garage-closet air handlers creates a specific set of problems: crushed runs, poorly sealed plenums, and coral-rock dust that newer cities with post-2000 construction simply don’t face. Our crews are trained to these conditions.
Cooling alone doesn’t control humidity inside the ductwork. In Miami Gardens’s climate, evaporator coils and duct interiors stay damp year-round, especially when the return plenum pulls humid outdoor or attic air through gaps. The mold grows on the duct surface and shows at the registers first. Cleaning the registers without addressing the moisture source and duct interior is temporary.
Real duct cleaning seals the system, applies negative pressure with HEPA containment, and uses rotary agitation tools to dislodge debris from the full length of each run. We provide before-and-after video inspection from our Rotobrush camera system so you see the difference. A surface vacuum of the registers takes twenty minutes; our full process takes 3 – 5 hours for a typical Miami Gardens home.
Yes, when source removal is done correctly. Removing accumulated coral-rock dust, mold spores, and construction debris from the full duct network reduces the particulate load your AC circulates. In homes where we’ve sealed return plenum gaps and cleaned evaporator coils, homeowners report less dust accumulation on surfaces and reduced musty odors within 24 – 48 hours. Call (361) 326-5060 for a free estimate.
