NOAA storm reports for Pinellas County show 2 hail days and 18 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Pinellas County also had 12 tornado days in that period. In Largo, 26.8% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.

Florida Licensing and Efficiency Rules
Florida is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Florida the company should carry a state license or registration. Ask for both.
Before You Hire
- Maintenance plans often put members first in line for emergency calls.
- Ask what the emergency fee is before the truck is sent.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
