Homes & equipment
Heating and cooling in Florida
Most homes use central heat pumps or AC with electric heat strips, with air handlers in garages, closets or attics. Concrete block homes are common, and many older homes still run on R-22 equipment.
Humidity control is central to comfort and to preventing mold, so correct sizing, good duct sealing and clean condensate drains matter more here than in most states.
Common problems
HVAC problems we see in Florida
Salt-air corrosion
Coastal outdoor units corrode quickly. Coated coils and fresh-water rinses help them last.
Hurricanes and outages
Storms cause flooding, debris damage and power surges. Units should be inspected after flooding before restarting.
Mold and drain clogs
Constant dehumidification makes clogged condensate drains and mold in air handlers common problems.

FAQ
Florida HVAC questions
How long do AC systems last in Florida?+
Often 10–15 years, and less near the coast, because of year-round use, humidity and salt air.
Should I run my AC after a hurricane flood?+
No. If the outdoor unit or air handler was under water, have it inspected before turning it on to avoid electrical damage and safety risks.
