Apex Air Duct Cleaning Service Miami has served Miami since 2015. We’re owner-operated and owner-present — Michael Brown arrives as the lead technician on every job, not a rotating subcontractor. Our 11 years of single-trade focus means we’ve worked inside virtually every duct configuration this city’s housing stock can produce, from 1950s concrete block with original in-slab supply lines to post-Hurricane Andrew rebuilds with attic-routed flex duct. We carry professional-grade Rotobrush and Nikro equipment on every van, and we don’t leave until we’ve shown you before-and-after documentation of your own system.

Why Miami Homes Are Different

Miami’s near-continuous, year-round AC operation combined with ambient relative humidity that rarely drops below 70% creates active mold colonization inside ductwork at a pace and scale unlike virtually any other major U.S. city. Every duct cleaning job in Miami is fundamentally a microbial remediation job first and a dust-removal job second — antimicrobial treatment isn’t an upsell here, it’s the baseline necessity that separates a competent contractor from one who leaves the root problem untouched.

A large share of Miami-Dade’s residential stock is 1950s–70s concrete block construction in neighborhoods like Hialeah, Little Havana, and Miami Shores, with many of those homes featuring original in-slab ductwork — supply lines cast directly into the concrete floor — that is chronically exposed to groundwater seepage from Miami’s extremely shallow water table. In older Hialeah and West Miami homes, technicians routinely pull debris that is visibly wet or muddy, not from a leak, but from decades of groundwater wicking through the slab directly into the duct channel. Post-Hurricane Andrew homes in South Dade were largely rebuilt with attic-routed flexible ductwork that degrades rapidly in attic temperatures exceeding 140°F, compounding condensation and mold issues. Miami AC systems deliver 55°F supply air into attic spaces that regularly exceed 140°F in summer, creating persistent condensation on flex duct exteriors — a thermal stress cycle that happens daily, year-round, with no natural dry-season interruption.

Air Duct Cleaning in Miami

Air duct cleaning in Miami demands more than standard vacuum extraction. Our ambient humidity and continuous cooling operation create microbial loads that seasonal-climate contractors don’t recognize, and our housing stock presents failure modes — groundwater-wicked slab ducts, heat-degraded flex duct — that simply don’t exist in markets with basements or crawl spaces. We approach every Miami job with video inspection first, so we’re quoting honest work based on what your system actually needs.

Our Air Duct Cleaning service covers residential and commercial systems across Miami-Dade, from single-family homes in Flagami to multi-zone rooftop units in Coral Gables. Here’s how we break down the work:

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. A standard residential duct cleaning for up to 12 vents runs $350–$650; with antimicrobial treatment included, most Miami homes fall in the $450–$850 range. 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. Commercial per-zone cleaning typically runs $400–$800 per zone depending on system complexity and access.

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. Full system cleaning with video inspection runs $650–$1,100 for most Miami homes. We won’t charge you for cleaning what we know will recontaminate within weeks.

Why do my in-slab ducts in Hialeah keep getting muddy even after cleaning?

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 inspect your system with a borescope camera to confirm whether this is what’s happening in your home.

Is antimicrobial treatment really necessary for every duct cleaning in Miami?

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.

Dryer Vent Cleaning in Miami

Dryer vent cleaning in Miami typically costs $149–$289 for a standard residential job, with most appointments completed in 60–90 minutes. Miami’s humidity fundamentally changes what’s inside your vent — the constant 70%+ relative humidity creates mold-colonized lint and dense, damp clogs that don’t occur in drier climates. We’ve extracted nests that completely blocked airflow and created fire hazards in homes near mature tree canopies in Westchester and Allapattah.

Our Dryer Vent Cleaning service addresses these Miami-specific conditions with professional equipment and honest assessment:

Vent Cleaning & Lint Removal

We clean with a Rotobrush rotary brush system combined with Nikro negative-pressure vacuum extraction. This matters in Miami because lint here isn’t just dry and fluffy — the ambient humidity above 70% year-round creates dense, partially damp lint clumps that cling to duct walls and resist less aggressive methods. We’ve seen centrifugal fans fail under the load of this Miami-specific lint density. Our process breaks it loose and extracts it completely, then we verify with a second camera pass. Standard dryer vent cleaning for a single-family home with accessible venting runs $149–$189.

Vent Rerouting

When a vent run is too long, too convoluted, or routed through compromised slab ductwork, rerouting is often the correct fix. We reroute through attic spaces or exterior walls using rigid metal ducting, never the flexible foil or plastic that degrades in Miami’s attic heat. Every reroute we install is calculated to meet or exceed local code for maximum run length and termination requirements. Vent rerouting with rigid metal ducting typically runs $289–$449 depending on the new path length and access points.

Bird Guard Installation & Vent Cap Replacement

This is where Miami’s storm exposure becomes critical. Standard vent caps fail in tropical storm conditions, allowing wind-driven rain directly into the duct. We install wind-rated caps with integrated bird guards — the mesh prevents nesting, and the cap design deflects wind and water. For homes in Westchester and Allapattah near mature tree canopies, bird guard installation isn’t optional. Bird guard or wind-rated vent cap installation runs $89–$149 when done with cleaning.

Does Miami’s humidity affect dryer vent cleaning more than other cities?

Yes — Miami’s humidity fundamentally changes what’s inside your vent. The constant 70%+ relative humidity creates mold-colonized lint and dense, damp clogs that don’t occur in drier climates. In a Little Havana home with 1950s concrete block construction, we found the dryer vent clogged not just with lint but with a slimy biofilm from moisture wicking through the slab. After a deep Rotobrush clean and installing a new bird guard, airflow returned to manufacturer specifications. Call (833) 628-3661 for a camera inspection of your vent.

How often should Miami homeowners get their dryer vents cleaned?

Most Miami homes need dryer vent cleaning every 12 months minimum; homes with large households, pets, or older vent configurations often need service every 6–8 months. The combination of high humidity and year-round heavy dryer use accelerates both lint production and microbial growth. We recommend annual inspection even if you don’t suspect a problem — camera verification catches issues before they become fire hazards or moisture damage. Schedule your inspection by calling (833) 628-3661.

HVAC Cleaning in Miami

HVAC cleaning in Miami typically costs $280–$650 for residential systems, with most jobs completed in a single visit. If your vents are pushing musty air or your energy bills are climbing, the problem usually isn’t just dust — it’s microbial growth thriving in our unique climate. We’ve spent 11 years working inside the duct systems that keep this city breathing, from Little Havana’s 1950s concrete block homes to the post-Andrew rebuilds in South Dade.

Our HVAC Cleaning service targets the components where Miami’s conditions cause the most damage:

Evaporator Coil Cleaning

The evaporator coil is where Miami’s humidity battle is won or lost. In our climate, coils become coated with biofilm — a living layer of bacteria and mold that standard brushing won’t remove. We use foaming cleaners followed by low-pressure rinsing, then apply antimicrobial treatment formulated for high-humidity environments. A dirty coil in Miami can reduce system efficiency by 30% or more, and we’ve measured that drop in homes from Westchester to Coral Way. Evaporator coil cleaning typically runs $180–$340.

Blower Cleaning

Blower wheels in Miami collect more than dust. They trap skin cells, pet dander, and mold spores that circulate through your home every time the system cycles. We remove the blower assembly, clean each blade with compressed air and solvent, and balance the wheel before reinstallation. In older Miami systems running 3,000+ hours annually, blower buildup is often the hidden cause of weak airflow. Blower cleaning runs $150–$280.

Air Handler Cleaning

The air handler is the central station of your HVAC system, and in Miami it’s also a condensation factory. We clean the drain pan, treat the cabinet interior with antimicrobial coating, and verify that condensate drainage isn’t backing up into the system. Standing water in an air handler is a mold incubator; we’ve found it in systems less than three years old. Air handler cleaning typically runs $200–$380, and full HVAC system cleaning including coils, blower, handler, and ducts runs $450–$850.

My Miami home has original in-slab ductwork from the 1960s. Is cleaning effective, or should I replace the ducts?

Cleaning is often ineffective for 1960s in-slab ductwork in Miami because the concrete channels chronically wick groundwater from our shallow water table. We recently serviced a 1960s concrete-block home in Miami Shores where the original in-slab ductwork was chronically wicking groundwater; when we pulled the registers, we found wet, muddy debris that had been accumulating for decades. After diagnosing that cleaning alone would be futile, we recommended sealing the slab runs and routing new flex duct. Call (833) 628-3661 for an honest assessment of your system.

Why does my flex duct in the attic feel damp after cleaning, even when I just had it serviced?

Your flex duct feels damp because Miami AC systems deliver 55°F supply air into attic spaces that regularly exceed 140°F in summer, creating persistent condensation on flex duct exteriors and at connections — a thermal stress cycle that happens daily, year-round, not seasonally. If your previous cleaner used standard vacuum techniques without inspecting for condensation damage or applying antimicrobial treatment at connections, they likely missed microbial colonization that’s now actively growing. We diagnose this with thermal imaging and scope inspection. Call (833) 628-3661 for a proper evaluation.

Duct Repair & Sealing in Miami

Duct repair and sealing in Miami typically costs $280–$750 for most residential jobs, with flex duct replacement running $180–$340 per run and full mastic sealing of an attic system ranging $450–$900. We’re owner-operated and owner-present in Miami — Michael Brown arrives as the lead technician on every job, not a rotating subcontractor. After 11 years and 867 verified reviews, we’ve learned that honest assessment matters more than selling the easiest fix.

Our Duct Repair & Sealing service addresses the specific failure modes Miami’s climate creates:

Duct Sealing with Mastic Sealant

Standard foil tape fails in Miami attics. We’ve pulled off tape that turned to powder after two summers at 140°F. That’s why we seal every connection with mastic — a fiber-reinforced, water-based compound that remains flexible and airtight through thousands of thermal cycles. In Miami’s humidity, mastic is the only sealant that maintains its bond when condensation forms on duct exteriors. A typical mastic sealing job for an attic system in Miami runs $450–$900 depending on access and duct count.

Flex Duct Repair & Replacement

Post-Hurricane Andrew homes across South Dade and newer construction in West Miami were built with attic-routed flexible ductwork. That material degrades predictably in Miami: the inner liner softens and collapses, insulation delaminates and sags, and the vapor barrier tears where it contacts truss nails. We recently replaced a rotted flex duct run in a Hialeah home’s attic, where the 140°F heat had softened the insulation liner, causing a collapse that blocked airflow. We installed a new Honeywell insulated flex duct and sealed all connections with mastic to prevent condensation recurrence. Single flex duct run replacement runs $180–$340.

Metal Duct Repair

Older Miami homes in neighborhoods like Little Havana and Miami Shores often have galvanized steel trunk lines in attics or soffits. These corrode at seams and where dissimilar metals contact — accelerated by Miami’s salt air infiltration through attic vents. We fabricate patch panels on-site, seal with mastic, and reinforce with mechanical fasteners. Metal duct section repair typically runs $220–$480 per section, with full trunk line replacement at $800–$1,600.

Why do my duct seals keep failing in my Miami home’s attic?

They fail because standard foil tape and cloth-backed duct tape degrade at sustained temperatures above 140°F, which Miami attics exceed daily for months at a stretch. The adhesive volatilizes, the backing embrittles, and humidity-driven condensation at the joint accelerates corrosion of any metal contact. We remove all old tape and seal with mastic, which remains flexible through thousands of thermal cycles. Call (833) 628-3661 and we’ll inspect what’s currently installed and quote proper remediation.

My Hialeah home has original in-slab ducts. Can they be repaired?

Partially, but honestly: in-slab ductwork in pre-1992 Miami-Dade homes is typically beyond cost-effective repair. The concrete channels are chronically exposed to groundwater wicking from Miami’s shallow water table — often just 3–6 feet below grade. We’ve opened slab ducts that contained standing water and active mold with no detectable plumbing leak. Sealing the interior of a concrete channel is temporary at best; the water finds new paths. Our honest recommendation is usually abandoning the slab runs and routing new ductwork through the attic or soffit. Call (833) 628-3661 for a camera inspection and straight assessment.

Air Quality & Sanitizing in Miami

Air quality and sanitizing service in Miami typically runs $350–$850 for residential antimicrobial treatment, with mold remediation in slab-duct systems ranging from $1,200–$3,500 depending on contamination severity and whether duct abandonment is needed. Most Miami homes require prompt scheduling because active mold colonies spread rapidly in our climate. We’ve spent 11 years working in conditions where skipping antimicrobial treatment means callbacks within a month.

Our Air Quality & Sanitizing service is built around Miami’s microbial reality:

Mold Treatment

In Miami, mold treatment isn’t a specialty service — it’s the baseline. Our AC systems push 55°F air through ductwork in attics that exceed 140°F, creating daily condensation cycles that never pause for a dry season. Every duct cleaning we perform includes antimicrobial application because vacuuming alone leaves active colonies that re-inoculate within 48 hours in this humidity. For homes with visible mold at registers or persistent musty odor, we apply EPA-registered fungistatic treatments and, when necessary, recommend full duct abandonment for failed in-slab systems. Residential antimicrobial duct treatment runs $350–$850; mold remediation with in-slab duct assessment runs $1,200–$3,500.

Bacteria Sanitizing

Bacterial loads in Miami ducts compound faster than in any market we’ve compared notes with — the combination of year-round cooling, high humidity, and organic debris from degraded flex duct insulation creates a perpetual incubation environment. Our bacteria sanitizing service applies hospital-grade disinfectants through the full duct run, not just surface-wiped registers. We target the biofilm layers that standard cleaning misses, particularly at flex duct connections where condensation pools.

UV Light Installation

UV-C germicidal lights installed at the air handler treat the air stream and coil surface — they don’t reach deep into ductwork. We install Honeywell and Abatement Technologies UV systems for Miami customers, but we’re direct about limitations: UV at the handler won’t fix mold growing in a distant flex duct run. For comprehensive protection, we pair UV installation with full duct antimicrobial treatment and, in new attic-routed systems, specify UV-resistant duct materials that won’t degrade under combined thermal and UV stress. UV-C light installation at the air handler runs $450–$950.

Why is antimicrobial treatment considered baseline in Miami, not an upsell?

Because Miami’s ambient humidity rarely drops below 70% and AC systems run continuously, any mold spores left after mechanical cleaning re-colonize within 48–72 hours. In drier climates, thorough vacuuming might suffice; here, it’s incomplete work. We include antimicrobial treatment in every Miami duct cleaning quote — call (833) 628-3661 for pricing specific to your system.

Can I really need full duct replacement in a 1960s Miami home instead of cleaning?

Yes, if the home has original in-slab ductwork. In Hialeah, Little Havana, and Miami Shores, we’ve opened registers to find saturated, muddy debris from decades of groundwater wicking through the concrete — not from a plumbing leak. Cleaning removes the symptom; the groundwater source remains. Full abandonment and attic re-routing is often the only permanent fix. We assess this with camera inspection during our free estimate. Call (833) 628-3661 to schedule.
