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.

We know the local building stock. The 1950s – 70s single-family homes and condo towers along Biscayne Boulevard and the Intracoastal often have original galvanized or flex duct systems that degrade differently than newer PVC or aluminum systems. That local knowledge changes how we inspect, how we clean, and when we recommend replacement instead.
Air Duct Repair in North Miami Beach
Air Duct Repair in North Miami Beach often starts with a camera inspection that reveals corrosion, separation at flex-duct joints, or mold growth on the interior of galvanized runs. We see this most in mid-century homes and older condo towers where salt-laden ocean air and year-round humidity have degraded the metal. Repair costs in North Miami Beach typically range from $200 – $450 for isolated section replacement, $450 – $850 for multiple runs, and $1,200 – $2,500 for full system replacement when corrosion is advanced.
Corroded Galvanized Duct Replacement
Original galvanized steel ducts in North Miami Beach homes from the 1960s and 1970s corrode from the inside out where condensation meets salt air. We cut out the compromised sections and replace them with sealed aluminum or fiberglass duct board, then seal all joints with mastic, not tape that will fail in the humidity.
Flex Duct Reconnection and Support
Flex duct in attic spaces sags, tears at connection points, or collapses entirely after years of heat cycling. We support new flex on proper strapping, seal with mechanical fasteners and mastic, and test static pressure before closing up so your system isn’t working harder than it should.
Ductwork Cleaning in North Miami Beach
Ductwork Cleaning in North Miami Beach is rarely just about dust removal. The tropical monsoon climate keeps HVAC systems running almost continuously, and the combination of humidity, salt air, and older duct materials creates conditions where mold and mildew colonize duct interiors year-round. A typical whole-system cleaning in North Miami Beach runs $350 – $650, with larger homes or heavily contaminated systems reaching $750 – $1,100.
Negative-Air Source Removal
We connect a Nikro negative-air machine to your trunk line, seal the registers, and use rotary brush agitation to dislodge debris while the vacuum pulls it out of the system. This prevents the contamination from circulating through your living space during cleaning, which is especially critical in North Miami Beach where mold spores are already prevalent.
Post-Storm Mold Remediation Cleaning
After water intrusion from hurricanes or summer downpours, ducts in low-lying areas like Eastern Shores and around the Oleta River often show visible mold growth. We set up contained negative pressure with HEPA filtration, perform source removal on affected supply and return runs, and document with before/after camera inspection for insurance submission.
Trusted Brands We Service in North Miami Beach
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for contained debris removal, and filtration products from Honeywell and Aprilaire that we install when homeowners want to maintain cleaner air between service visits. We don’t use hardware-store shop vacs or consumer-grade tools. The equipment we bring is the same gear commercial crews use in hospitals and schools, and we explain what each piece does while we’re working so you understand why it matters for your system.
Common Air Duct Cleaning Problems We See in North Miami Beach Homes
- Mold and mildew in original galvanized ducts. The salt-laden ocean air and near-constant humidity in North Miami Beach corrode the interior of galvanized ductwork from the 1960s and 1970s, creating pits where mold colonies establish and recirculate spores through central AC systems running year-round.
- Water intrusion in low-lying neighborhoods after storms. Ground-floor units in Eastern Shores and near the Oleta River frequently take on moisture during summer downpours or hurricane season, leading to musty odors and visible mold that requires documented cleaning for insurance claims.
- Flex duct degradation in condo towers. High-rise buildings along the Intracoastal and Biscayne Boulevard corridor often have original flex duct that has become brittle, sagging, or detached at joints after decades of heat and humidity cycling in unconditioned ceiling plenums.
- Inadequate previous cleanings that spread contamination. We find systems where previous crews failed to seal the air handler and blower motor during cleaning, blowing dislodged mold spores and debris into living spaces instead of removing them, which is why we use contained negative pressure on every job.
Pricing for Air Duct Cleaning in North Miami Beach, FL
Whole-home residential duct cleaning in North Miami Beach typically runs $350 – $650 for a standard single-family system with 10 – 15 supply and return registers. Larger homes, heavily contaminated systems, or post-storm mold remediation work can reach $750 – $1,100. Commercial systems in condo towers or small businesses start around $800 and scale with system complexity.
What moves the price: the number of registers, accessibility of duct runs, presence of mold requiring HEPA containment, and whether camera inspection reveals corrosion that requires repair or replacement before cleaning is worthwhile. We give you one flat price per system, agreed in writing before work starts. No per-vent add-ons. No charges that appear after the technician is inside.

FAQs About Air Duct Cleaning in North Miami Beach
Camera inspection is the only way to know for certain. We feed a scope through your supply and return registers to check for structural corrosion of galvanized metal, separation of flex duct, and the extent of mold colonization. If the duct material is intact and the contamination is surface-level, negative-air source removal with HEPA containment will handle it. If the salt air and humidity have corroded the metal through or the flex has degraded to the point of tearing, replacement is the only permanent fix, and we’ll document both conditions with photos for your insurer. Call (361) 326-5060 to schedule inspection.
Salt-laden ocean air accelerates corrosion inside metal ducts, creating pits and rough surfaces where mold spores anchor and colonize. Combined with near-constant HVAC operation in the tropical climate, ducts here never fully dry out, so mold grows year-round instead of seasonally. Inland Broward and Westchester see similar humidity but less salt corrosion, which means their duct interiors stay smoother and less hospitable to mold. This is why North Miami Beach duct cleaning often involves mold remediation, not just dust removal.
Yes. We photograph and video every stage: the initial camera inspection showing contamination, the contained cleaning process with negative-air setup, and the post-cleaning verification showing source removal was achieved. After a summer storm pushed water into a ground-floor unit near Eastern Shores, our tech pulled a supply register and found visible mold growth on the original galvanized duct interior. We set up negative pressure with HEPA filtration, used agitation tools to perform source removal on the affected supply and return ducts, and documented everything with before/after camera inspection so the homeowner’s insurer accepted the cleaning claim without requiring full duct replacement. We provide this documentation package on every post-storm job.
Most North Miami Beach homeowners need duct cleaning every 2 – 3 years, compared to the 3 – 5 year interval typical in drier climates. The combination of salt air corrosion, year-round humidity, and continuous HVAC operation means debris and mold accumulate faster here. Homes in low-lying flood-prone areas or with original 1960s – 70s ductwork may need annual inspection to catch corrosion before it becomes a replacement job. Call (361) 326-5060 and we’ll assess your specific system.
We use Rotobrush rotary brush systems for mechanical agitation inside duct runs, Nikro negative-air machines to maintain contained vacuum pressure during cleaning, and Aprilaire and Honeywell filtration products when upgrading your system’s air cleaning capability. This is professional-grade equipment, not consumer gear, and it’s the same setup we use on commercial jobs. We explain what each piece does while we’re working so you understand how the cleaning is being performed.
