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 Key Biscayne
Air duct cleaning in Key Biscayne runs $350 – $750 for most single-family homes and $180 – $400 per unit in condo buildings, with full-system cleanings typically completed in one visit. We’re familiar with the island’s unique challenges: salt-laden humidity, shared vertical duct chases in towers, and elevated homes on stilts that take in storm-driven air through roof vents. Our crews dispatch from our Miami South FL office and carry the tools and permits needed for both waterfront houses and high-rise associations. Call (361) 326-5060 for a written estimate before any work starts.
Why Hollis Air Duct Cleaning Is Key Biscayne’s Preferred Air Duct Cleaning Company
We’ve been serving barrier-island homes since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning in Key Biscayne reputation is built on showing up inside the window and pricing in writing. Our technicians are background-checked, uniformed, and trained to The Garrison Standard: arrive squared away, explain the scope, complete the job by the book, and leave the site clean.
Key Biscayne customers call us back because we understand what mainland crews miss. The island’s year-round A/C use means ducts never get a seasonal dry-out. Salt aerosol from Biscayne Bay and the Atlantic settles inside metal trunks and corrodes galvanized steel that was installed in the 1970s and 80s. We check for chloride pitting and microbial growth that routine dust-cleaning overlooks.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Commercial Air Duct Cleaning in Key Biscayne
Commercial Air Duct Cleaning in Key Biscayne covers the shared HVAC systems in condo towers, mid-rise associations, and small commercial properties from Crandon Boulevard to the harbor. These buildings use rooftop air handlers and long vertical chases that serve dozens of units, so one contaminated riser can affect multiple floors. A typical commercial duct cleaning in Key Biscayne runs $800 – $2,500 depending on chase count, access difficulty, and whether negative-air containment is required by the building association.
Condo Tower and Association Work
Buildings like Key Colony, Grand Bay, and Ocean Club require pre-approved work orders and often mandate HEPA containment during duct cleaning. We coordinate with property managers, secure loading-dock access, and set up Abatement Technologies negative-air units before opening any shared chase. Skipping this step gets crews turned away at the dock.
Post-Storm Commercial Inspection
After tropical weather, saltwater-laden air enters rooftop intakes and leaves chloride deposits in commercial handlers. We inspect coils, drain pans, and supply plenums for corrosion that standard mainland cleaning protocols miss. Early detection prevents expensive handler replacement.
Air Duct Cleaning Services in Key Biscayne
Air Duct Cleaning Services in Key Biscayne address a problem mainland Miami pages get wrong: this is not dry-dust removal. The island’s tropical monsoon climate, 70 – 80% relative humidity, and constant A/C operation create a salt-and-mold remediation challenge inside ductwork. A typical residential full-system cleaning in Key Biscayne runs $350 – $750, with video inspection, rotary brush agitation, and negative-air extraction included. Condo unit cleanings run $180 – $400 per system.
Residential Full-System Cleaning
We clean supply ducts, return ducts, and trunk lines using Rotobrush rotary brush systems and Nikro negative-air machines. On elevated homes near Harbor Drive or Mashta Point, we inspect for salt-corrosion pitting in original galvanized trunks and failing flex patches from past storm repairs.
Video Inspection and Documentation
Every job includes before-and-after camera footage of your own ducts. You’ll see the salt buildup, biological growth, or lint accumulation we found. This documentation satisfies condo board requirements and proves the work was actually performed.

Trusted Brands We Service in Key Biscayne
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and Abatement Technologies HEPA filtration for containment work in shared buildings. We also install and service Aprilaire and Guardsman filtration products for homeowners who want upgraded protection against salt aerosol and organic particulates.

Common Air Duct Cleaning Problems We See in Key Biscayne Homes
- Salt-aerosol corrosion in 1970s galvanized ductwork. Storm-driven air from Biscayne Bay and the Atlantic carries chloride that pits metal trunks from the inside. At a 1970s elevated home on Harbor Drive near the Key Biscayne Yacht Club, our techs found original galvanized supply trunks pitted with white salt-corrosion and wrapped in failing flex patches from past storms. We ran camera inspection on the riser, set up negative pressure with Abatement Technologies HEPA units, and used agitation tools to pull out salt-laden debris before recoating the interior. The homeowner had been running the A/C every day for 15 years – no seasonal dry-out, which meant biological growth was feeding on condensed moisture year-round.
- Shared vertical chases in condo towers. Buildings like Key Colony use duct risers that serve multiple units. One contaminated chase spreads odors and particulates floor to floor. Cleaning only your unit’s register connection leaves the main riser untouched.
- Moisture intrusion after hurricane-season flooding. Key Biscayne’s high water table and wind-driven rain mean ducts in elevated homes and rooftop handlers often stay wet for weeks. Musty microbial contamination follows. We treat this as remediation, not routine maintenance.
- Shared dryer vent stacks with accumulated lint. Mid-rise towers link dozens of units through one vertical lint pathway. Cleaning only the individual trap section leaves the bulk of flammable material in the shared run, which is the leading factor in home dryer fires.

FAQs About Air Duct Cleaning in Key Biscayne
Condo towers at Key Colony and similar buildings use shared vertical chases that connect multiple units, so one crew’s work can affect neighbors’ air quality. Associations require pre-approval, loading-dock scheduling, and HEPA containment to prevent cross-contamination. We handle this paperwork before arrival so our techs aren’t turned away at the dock. Call (361) 326-5060 and we’ll coordinate with your property manager.
Key Biscayne’s elevated homes take in saltwater-laden air through roof vents and A/C intakes, leaving chloride deposits that pit galvanized duct interiors. Mainland homes deal with dry dust; island homes need salt-corrosion inspection and often mold remediation before standard cleaning begins. We check for this on every elevated-home job. Call (361) 326-5060 for an inspection estimate.
Relative humidity stays at 70 – 80% and A/C runs almost daily, so condensate and organic buildup never get a seasonal dry-out period. We recommend inspection every 2 – 3 years for island homes versus 3 – 5 years for mainland properties that get natural ventilation months. Call (361) 326-5060 to schedule.
Yes. Shared vertical stacks in mid-rise towers link dozens of units through one lint pathway, and cleaning only the individual trap leaves the bulk of flammable material in the shared run. We access the full vertical run with rotary tools and negative-air extraction, coordinated with building management. This service runs $400 – $900 depending on height and access. Call (361) 326-5060 for a written quote.
Check for musty odors, reduced airflow, or visible moisture in registers, all signs that wind-driven rain or saltwater-laden air entered the system. On Key Biscayne, every post-hurricane duct cleaning includes salt-aerosol corrosion checks on galvanized 1970s-era ductwork because storm-driven saltwater air enters through roof vents and A/C intakes, leaving chloride deposits that pit metal and accelerate rust in a way mainland Miami homes never see. If you suspect intrusion, call (361) 326-5060 for a video inspection before running the system continuously.
