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.

Our Main Key Biscayne Services
Most Key Biscayne homeowners call us for one of three jobs. Each has its own page with detailed pricing and local specifics.
Air Duct Cleaning in Key Biscayne
We clean residential duct systems using Rotobrush rotary brush systems and Nikro negative-air machines to dislodge and extract buildup. In Key Biscayne, this means addressing salt corrosion inside metal trunk lines, biological growth in flex duct runs under elevated homes, and condensate-soaked insulation that mainland crews rarely encounter. Condo towers like Key Colony and Grand Bay require coordination with building management for rooftop air handler access. Air Duct Cleaning in Key Biscayne
Dryer Vent Cleaning in Key Biscayne
Dryer vent cleaning here runs $150 – $275 for most Key Biscayne homes, though elevated homes on stilts with long horizontal runs through crawl spaces can run higher. Salt air accelerates lint compaction in exterior vent caps, and hurricane-grade construction often means tighter wall penetrations that trap moisture. We clear the full run from appliance to termination and check back-pressure with a manometer. Dryer Vent Cleaning in Key Biscayne
Duct Sealing in Key Biscayne
Duct sealing with mastic and metal-backed tape addresses the air loss that drives up Key Biscayne cooling bills year-round. Elevated homes often have patched galvanized duct from the 1970s – 80s with gaps at storm-damaged joints, while condo risers develop leaks where vertical chases meet horizontal branch lines. We seal what we can access and document what requires further repair. Duct Sealing in Key Biscayne

Why Key Biscayne Homes Are Different
Key Biscayne sits between Biscayne Bay and the Atlantic Ocean on a barrier island with a high water table and no winter dry season. Relative humidity stays at 70 – 80% or higher most months, and the marine air carries salt aerosol that settles inside ductwork and corrodes metal components. A/C runs almost every day of the year, so condensate and organic buildup never get the seasonal break that mainland systems do.
The housing stock compounds these conditions. The island’s 1970s – 2000s waterfront homes on stilts or elevated slabs often have original galvanized or flex duct that has been patched after decades of storms and remodels. Meanwhile, mid- and high-rise condos like Ocean Club, Grand Bay, and the Key Colony complexes use long vertical chases and rooftop air handlers where one contaminated riser can affect multiple units. After tropical storms or hurricanes, saltwater-laden air enters through roof vents and A/C intakes, meaning the first post-storm duct cleaning is often closer to mold remediation than standard maintenance. Many condos require building-association approval and negative-air containment before work begins because ducts share vertical chases with neighbors.

FAQs About Air Duct Cleaning Company in Key Biscayne
Yes, most condo associations in complexes like Key Colony and Grand Bay require written approval before any work on shared duct chases or rooftop air handlers. We provide the containment plan and insurance documentation your building manager needs. Call (361) 326-5060 and we’ll walk you through the approval steps before scheduling.
If your home or building took wind-driven rain or had A/C intakes exposed to salt-laden air, schedule an inspection within two to four weeks. Salt corrosion and microbial growth accelerate quickly in Key Biscayne’s humidity, and early cleaning prevents permanent duct damage. We assess moisture intrusion and recommend containment if microbial contamination is present.
We access most elevated home ductwork through existing registers, crawl-space hatches, and exterior plenum doors. Original 1970s – 80s galvanized duct under Key Biscayne homes is often too deteriorated for aggressive mechanical cleaning, and we’ll tell you honestly if replacement makes more sense than cleaning. The written price covers the inspection and cleaning scope we agree to before starting.
