Fast, Reliable Air Duct Cleaning Across Miami
Air duct cleaning in Miami typically costs $350–$850 for a standard residential system, with most jobs completed in a single visit. For homes with in-slab ductwork or active microbial contamination, full system restoration can run $1,200–$2,800 — and in those cases, cleaning alone often isn’t the right starting point.
We’ve been working in Miami for 11 years, and our Air Duct Cleaning team knows the difference between a straightforward maintenance job and a situation where the ductwork itself has failed. From Allapattah to Miami Shores, we carry Rotobrush and Nikro equipment that matches what commercial restoration contractors use — because in this climate, residential duct cleaning demands that level of capability.

Why Apex Air Duct Cleaning Service Miami Is Miami’s Preferred Air Duct Cleaning Company
Owner Michael Brown serves as lead technician on every Miami job. That’s not a marketing line — it’s how we operate. When you call Apex, the person accountable for our 867 verified reviews at 4.9 stars is the same person who shows up at your door. No rotating subcontractors, no franchise crew where you never see the same face twice.
Our response time to Miami neighborhoods — Flagami, West Miami, Westchester, Allapattah — is built around being local and owner-operated. We’re not dispatching from Fort Lauderdale or sending crews who need GPS to find Coral Way. Michael knows the housing stock: which blocks in Hialeah have original 1950s slab construction, which post-Andrew rebuilds in South Dade have flex duct baking in 140°F attics, and why those differences completely change what “duct cleaning” needs to mean.
That local knowledge saves Miami homeowners from wasted money. We’ve seen competitors charge for full cleaning when a two-minute video inspection would have shown groundwater intrusion making cleaning pointless. We’ve seen crews skip antimicrobial treatment because they treat Miami like Atlanta — as if mold here were seasonal, not perpetual. Our reviews reflect that we don’t do that.
Our Air Duct Cleaning Services in Miami
Residential Duct Cleaning
Most Miami homes we service run their AC 10+ months a year, pushing conditioned air through ductwork that never gets a dry-season break. Our residential process starts with negative-pressure extraction using Nikro portable HEPA systems, followed by rotary brush agitation with Rotobrush equipment — the same gear restoration contractors use after water damage. In Miami’s humidity, we treat antimicrobial application as baseline, not upsell. For homes near Biscayne Bay or in low-lying areas like parts of Allapattah, we also check for salt-air corrosion on metal register boots and connections.
Commercial Duct Cleaning
Miami’s commercial buildings — from Coral Gables medical offices to Little Havana restaurants — face accelerated duct contamination from continuous occupancy and kitchen exhaust proximity. We scale our Nikro negative-pressure systems to handle multi-zone rooftop units common in Miami’s flat-roof commercial stock. Our 11 years of single-trade focus means we understand how Miami-Dade’s energy codes affect commercial HVAC configurations, and we clean without disrupting tenant operations. Owner Michael Brown personally scopes commercial jobs to determine whether after-hours scheduling or sectioned cleaning makes more sense.
Supply Duct Cleaning
Supply lines carry 55°F air into your living space — and in Miami, they’re where we most often find active mold colonization. In slab-on-grade homes from the 1950s–70s, supply ducts cast directly into concrete can wick groundwater from Miami’s shallow water table, making the debris we pull out visibly wet or muddy. That’s not a cleaning problem; that’s a duct failure. Our supply duct service includes video inspection to distinguish between contamination that can be cleaned and intrusion that requires sealing or replacement. We won’t charge you for cleaning what can’t be cleaned.
Return Duct Cleaning
Return ducts pull air back to the handler, and in Miami they act as the system’s lungs — constantly drawing in humid, particle-laden air. Returns in older Miami homes often use wall cavities or unlined chases that harbor decades of accumulation. Our rotary brush and negative-pressure combination reaches the full return path, including plenum connections where Miami’s high humidity causes condensation pooling. For homes in Flagami or West Miami with original construction, we pay particular attention to return pathways that may have been modified or damaged during decades of renovation.
Full System Cleaning
Full system cleaning means every component: supply ducts, return ducts, plenums, registers, grilles, and the air handler cabinet. In Miami, this is often the right scope because partial cleaning leaves active contamination that simply recolonizes the cleaned sections. Our full-system jobs include before-and-after video documentation — particularly important when we’re documenting groundwater intrusion or flex duct degradation for insurance or real estate disclosure purposes. From cleaning to repair to sanitizing, it’s handled in one visit by the same technician.
Video Inspection
We recommend video inspection for every Miami job involving older construction or suspected moisture issues. Our borescope cameras navigate duct interiors to show you — and us — exactly what we’re dealing with before we quote work. In a 1950s Hialeah home with original in-slab ductwork, we pulled wet, muddy debris from a supply register. After video inspection showed groundwater intrusion through the slab, we recommended sealing the runs and installing new attic-routed flex ducts — the only way to stop recurring microbial growth. That honesty is why we have 867 reviews at 4.9 stars. Video inspection in Miami typically runs $150–$250 as a standalone service, or it’s included with full system cleaning.

Trusted Brands We Service in Miami
We operate professional-grade Rotobrush and Nikro equipment — rotary brush systems and negative-pressure vacuums built for commercial restoration work, not consumer shop vacs with duct attachments. For air quality improvements, we work with Honeywell and Aprilaire filtration and purification products, and we stock Guardsman antimicrobial treatments formulated for high-humidity applications. Miami’s climate destroys equipment that isn’t built for it; we’ve selected brands that hold up. Parts and treatments are carried on our service vehicles, so most Miami jobs don’t wait on ordering.
Common Air Duct Cleaning Problems We See in Miami Homes
- Groundwater wicking into in-slab ductwork. In Hialeah, Little Havana, and Miami Shores, original concrete-embedded supply lines draw moisture from Miami’s shallow water table. The debris we extract isn’t dusty — it’s wet and muddy. Cleaning these ducts without first sealing or abandoning the runs wastes your money; the moisture returns within weeks.
- Post-Andrew flex duct degraded by attic heat. Homes rebuilt after Hurricane Andrew with attic-routed flexible ductwork now have insulation jackets and inner liners breaking down from years of 140°F+ summer temperatures. Severely kinked or collapsed sections can’t be cleaned effectively — they need replacement, and we’ll show you on video exactly where.
- Active mold colonization treated as “dust.” Miami’s year-round humidity and continuous AC operation create microbial loads that seasonal-climate contractors don’t recognize. Skipping antimicrobial treatment means the problem returns. We don’t treat it as an upsell because in Miami, it’s the actual job.
- Condensation at supply connections. Where 55°F supply air meets Miami’s 140°F attic spaces, thermal stress creates daily condensation cycles. We find rusted boots, separated flex connections, and water-stained ceiling drywall — all signs that the duct system needs sealing and insulation repair, not just cleaning.

FAQs — Air Duct Cleaning in Miami
Groundwater from Miami’s shallow water table is wicking directly through the concrete slab into your duct channels — it’s not a leak you can fix, it’s the construction method itself. Cleaning removes the debris but does nothing to stop new moisture from entering, so the mud returns within weeks. The honest solution is sealing the slab runs and routing new flex duct through the attic or soffit. Call (833) 628-3661 and we’ll video-inspect to confirm the intrusion pattern — estimates are free.
Yes — in Miami’s climate, antimicrobial treatment is baseline, not optional. Our ambient humidity rarely drops below 70%, and year-round AC operation creates continuous condensation inside ductwork that supports active mold colonization. Cleaning without antimicrobial application leaves live spores that recolonize within days. We use Guardsman treatments formulated for high-humidity environments as standard on every Miami job. Call (833) 628-3661 for specifics on our treatment protocol.
Post-Andrew flex duct in Miami attics is actually more prone to degradation than mold specifically — the 140°F+ attic temperatures break down the insulation jacket and inner liner, creating tears and gaps where condensation collects and then microbial growth follows. The flex duct installed in the 1990s is now 30+ years old, past its designed service life in this climate. We video-inspect these systems to distinguish between cleanable contamination and duct that needs replacement. Call (833) 628-3661 to schedule an inspection.
We can clean them, but we often recommend against it if video inspection shows groundwater intrusion — in-slab ducts in Miami’s older neighborhoods like Hialeah and Little Havana frequently have this issue. Cleaning wet ducts is futile; the moisture source is the slab itself. Our honest assessment may be sealing those runs and installing new attic-routed ductwork. We’ve built our reputation on making this distinction, not on selling cleaning that won’t last. Call (833) 628-3661 for a free evaluation.
Miami’s near-continuous AC operation and ambient humidity above 70% create active mold colonization inside ductwork at a pace unlike virtually any other major U.S. city — there’s no dry-season interruption to break microbial growth cycles. Every duct cleaning job here is fundamentally microbial remediation first and dust removal second. Contractors who treat Miami like Atlanta or Houston miss this entirely. Our 11 years of single-trade focus in this market means we don’t. Call (833) 628-3661 to discuss your specific situation.
