Air Duct Cleaning in Miami - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Miami, FL

Dryer vent cleaning in Miami is a different job than anywhere else in Florida because half the city’s clothes dryers vent through concrete walls or into under-slab duct cavities that predate modern building code. We see lint accumulations that turn into wet paste within weeks during the June-to-October rainy season, and that paste is the leading cause of dryer fires in Miami-Dade’s 1950s-1970s CBS housing stock. Call (806) 606-6902 and Tomas Reyes or one of our Miami crew leads will walk you through what we’ve found in homes like yours.

Why Miami Homes Are Different

Miami’s AC systems run essentially 365 days a year and the outdoor humidity routinely sits above 80%, even at night. That means ductwork never fully dries between cooling cycles. The result is persistent condensation inside ducts, which accelerates fiberglass liner breakdown in attic flex duct and feeds mold growth in under-slab runs. Any small leak or insulation gap stays wet for months, not days.

Most of Miami-Dade’s residential stock is CBS concrete block built between the 1950s and 1970s. Many of those homes have ducts running beneath the concrete slab or flex duct strung through attics that hit 150°F in summer. After a heavy afternoon thunderstorm, low-lying neighborhoods like West Miami and parts of Hialeah see standing water back up into under-slab ducts, where it sits in 90°F heat. That turns into a mold reservoir that blows spores into living spaces. High-rise condos in Brickell and Downtown are a separate story entirely: they run fan-coil units rather than central ducted systems, so the cleaning focus shifts to coils and drain pans.

Technicians working Little Havana and the older streets off Coral Way regularly find original under-slab ductwork that has never been opened since the house was built. Duct cleaning in Miami, in other words, is not routine maintenance here. It’s the only way to see what forty or fifty years of humidity and stormwater have left inside the system.

Our Main Miami Services

Two services account for most of the calls we take from Miami homeowners, and each has its own dedicated Miami page where we lay out local pricing and the specific conditions our crews find here.

Air Duct Cleaning in Miami

The service covers full-source removal from the plenum through every duct run to the registers, using negative-pressure extraction with equipment from Rotobrush and Nikro. In Miami the work often turns up what high humidity leaves behind: fiberglass particles, mold on the inner liner, or debris from under-slab water intrusion. Full details and pricing are on the Air Duct Cleaning in Miami page.

HVAC Cleaning in Miami

HVAC cleaning here targets the blower, coil, drain pan, and plenum, not just the ducts. In Miami’s year-round run cycle, drain pans accumulate biofilm that feeds on the constant moisture, and coils in high-rise fan-coil units need a different approach than trunk-line systems in single-family CBS homes. Read what’s involved and what it costs on the HVAC Cleaning in Miami page.

Dryer Vent Cleaning in Miami

Dryer vent cleaning in Miami starts with a camera inspection of the full run from dryer to exterior termination. In CBS homes the vent often runs through a masonry wall and out a stucco soffit, which is a longer, harder run than the short straight vents common in newer construction. When humidity stays above 80% for months, lint behind the dryer and inside the run absorbs moisture and hardens into a compacted layer that restricts airflow and keeps the dryer running long past its normal cycle time. That’s when we see Miami homeowners calling with dryers that take two or three cycles to dry a normal load. Our Dryer Vent Cleaning crews document every run with before and after photos as part of the standard job record.

Dryer Vent Inspection

Signs you need it

Clothes come out damp after a full cycle, or the outside vent hood does not open clearly when the dryer is running.

What it costs in Miami

A standalone inspection runs $95-$145 in Miami, and the fee is credited toward cleaning if we do the work the same visit.

How we do it

We run a camera from the dryer connection to the exterior termination and record the full run, then hand you a written scope with photos of every obstruction we found.

Lint Removal

Signs you need it

Visible lint caked around the dryer connection, longer dry times, or a faint burning smell when the dryer has been running for a while.

What it costs in Miami

Full lint removal runs $120-$180 in Miami depending on run length and access, paid as one flat price before we start.

How we do it

We brush the full run and extract the loosened lint with a HEPA-filtered vacuum, then photograph the interior at the start, middle, and end of the run.

Vent Rerouting

Signs you need it

The existing vent run is over 35 feet, has more than two elbows, or terminates into a soffit or roof jack that traps lint and moisture.

What it costs in Miami

Rerouting typically runs $220-$400 in Miami, determined by run length, wall material, and the number of new termination penetrations.

How we do it

We map the shortest allowable route, cut the new termination through wall or roof, install rigid-metal duct, and seal each joint with mastic.

Bird Guard Installation

Signs you need it

You hear birds or scratching inside the vent hood, or you’ve pulled nesting material out of the exterior termination.

What it costs in Miami

Bird guard installation runs $80-$120 in Miami when added to a cleaning or rerouting job, and slightly more as a standalone visit.

How we do it

We mount a stainless steel or galvanized guard over the termination opening and photograph the finished installation for your record.

What Dryer Vent Cleaning Costs in Miami

Every price above is written before work starts, under Haven Standard Clause 1, so there is no per-foot upcharge discovered after the crew arrives.

How often should a dryer vent be cleaned in Miami?

Every 10 to 12 months in a single-family Miami home, and every 6 to 8 months if the dryer is used daily or the vent run is long or has multiple elbows. Miami’s humidity turns loose lint into a paste faster than in drier climates, so an annual date on the calendar is the minimum for most households. Call (806) 606-6902 to schedule and we will give you a written scope before the work begins.

Does cleaning actually reduce fire risk in a Miami home?

Yes, because the leading cause of dryer fires is accumulated lint inside the vent run, and in Miami that lint stays damp and dense longer than it would in a dry climate. A camera-tested clean run restores airflow to manufacturer specifications. We photograph the before and after so you can verify the work, and the 365-Day Done Right Promise covers it in writing.

Duct Repair & Sealing in Miami

Duct repair and sealing in Miami starts with finding where the system is leaking. In under-slab ductwork from the 1950s-1970s CBS era, the leaks are often cracks in the concrete shell or failed joints where the slab has settled. In attic flex duct, the leaks are usually loose or missing zip ties, punctured outer jackets, or fiberglass liner that has broken down after years of 150°F attic heat. The humidity here makes every leak visible fast: a cold duct blowing conditioned air into a damp attic space produces condensation and mold on the outside of the run. Our Duct Repair & Sealing crews find these leaks with a pressure test before any repair is quoted, so the written scope reflects what’s actually leaking, not a guess.

Flex Duct Repair

Signs you need it

A collapsed or kinked flex run in the attic, or visible condensation and mold forming on the outside of the duct jacket.

What it costs in Miami

Flex duct repair runs $180-$350 per section in Miami, depending on run accessibility and whether the section is patched or replaced.

How we do it

We cut out the damaged section, install a properly stretched replacement, seal both ends with mastic and UL-181 tape, and photograph the finished joints.

Duct Sealing

Signs you need it

Rooms at the end of the run stay warm and muggy, energy bills creep upward, or a pressure test shows leakage over the allowable threshold.

What it costs in Miami

Duct sealing runs $300-$800 for a single-family Miami home, depending on total linear footage and how many joints require access.

How we do it

We seal each accessible joint with mastic and embed the photo record from inside the duct run before and after the work.

Mastic Sealant

Signs you need it

Gaps at the plenum connection, register boots, or around the air handler cabinet where conditioned air escapes into unconditioned space.

What it costs in Miami

Mastic sealing on its own starts at $150 in Miami and scales with the number of connections and linear feet treated.

How we do it

We apply a brush-grade mastic to every joint in the work scope, then photograph the sealed connections from inside the duct where access allows.

What Duct Repair & Sealing Costs in Miami

Every repair quote is a single written number agreed before any panel comes off, and the 365-Day Done Right Promise covers the work in writing.

Why are leaky ducts a bigger deal in Miami than in other Florida cities?

Because the AC runs year-round and the indoor RH rarely gets low enough to dry things out. A small duct leak in Miami produces continuous condensation for months, which becomes mold on the duct jacket and inside the attic insulation. Sealing the leak is the only repair that addresses the root cause. Call (806) 606-6902 and we will pressure-test the system and put the fix in writing.

Can you repair under-slab ducts in Miami without tearing out the slab?

Yes, in many cases we can line the existing under-slab run or route a new flex run through a chase or soffit rather than jackhammering concrete. The right approach depends on what the camera shows inside the slab and where the run sits relative to the foundation. The written quote you receive follows the same Haven Standard Clause 1 rule as every other job.

Air Quality & Sanitizing in Miami

Air quality and sanitizing in Miami is about what is growing inside the system, not just what is blowing through it. The flat limestone terrain and intense summer rainstorms make standing water inside under-slab ducts routine, and standing water in 90°F heat becomes a mold reservoir in a matter of days. High-rise condos in Brickell and South Beach have a different issue: fan-coil drain pans that never fully dry, producing biofilm and organic odor that recirculates through the unit. Our Air Quality & Sanitizing work starts with a camera inspection of the surfaces that can actually be treated, because sanitizing without seeing the contamination first is just spraying into the dark.

Mold Treatment

Signs you need it

A persistent musty or earthy smell from the registers, visible on the duct liner or grille, or recent standing water in under-slab runs.

What it costs in Miami

Mold treatment runs $250-$360 for a targeted section and $450-$900 for a full system in a Miami single-family home.

How we do it

We apply a registered antimicrobial to the affected surfaces after mechanical cleaning, then photograph the treated area and document the product batch in your job record.

Odor Removal

Signs you need it

The system smells like wet insulation, stale water, or something organic every time the blower kicks on, especially in older CBS homes after heavy rain.

What it costs in Miami

Odor removal runs $200-$375 in Miami, and is typically bundled with the cleaning or treatment that removed the source.

How we do it

We clean or replace the affected surface, then run an odor-neutralizing treatment through the system and verify with a post-treatment photo record.

UV Light Installation

Signs you need it

Mold or biofilm recurs within a year of cleaning, or the coil and drain pan stay wet continuously because the system never stops running.

What it costs in Miami

UV light installation runs $350-$600 per unit in Miami, depending on the lamp type and whether the coil, plenum, or both get coverage.

How we do it

We mount the lamp at the coil or upstream of it, wire it to a dedicated circuit, and document the installation with the lamp’s spec sheet in your record.

Air Purifier Install

Signs you need it

Household members with allergies or asthma report symptoms that improve away from home, or the home sits near a busy corridor where fine particulate loads are high.

What it costs in Miami

Air purifier installation runs $400-$750 in Miami, with the unit selected for the system’s airflow rather than a one-size-fits-all pick.

How we do it

We install the unit in the supply plenum or return, wire it to the blower control, and photograph the finished mount and electrical connection.

What Air Quality & Sanitizing Costs in Miami

Every one of those numbers is the full written price you sign off on before work starts, under Haven Standard Clause 1.

Is mold in Miami ducts dangerous for my family?

It depends on the species and the amount, and that’s exactly why we camera first and treat second. The spores from a mold reservoir inside an under-slab duct blow directly into bedrooms and living areas every time the blower runs. The camera image tells us whether what you are seeing is surface staining, active growth, or a deeper reservoir. Call (806) 606-6902 if you want that image before you decide.

Why does the musty smell come back after a regular duct cleaning in Miami?

Because the source was never treated. Cleaning removes loose debris but does nothing to kill mold embedded in duct liner or under-slab concrete. In Miami’s humidity, the colony regrows within weeks. The fix is a documented mold treatment on the affected surfaces after the cleaning, then a photo of the post-treatment surface so you can see the difference.
