Avoid in Key Biscayne
- Skipping coil drainage during multi-day power outages — standing water in the pan grows bacteria fast.
- Returning home post-storm and running the AC immediately without a system inspection.
- Cheap insulated flex duct in attic installs — humidity here destroys low-grade product within seasons.
- Single-stage hurricane shutters that don't seal vent terminations — driven rain enters the duct system.
