Licensing and permits
AC installation and replacement in Florida requires a Class A or B air-conditioning contractor (or mechanical contractor) licensed through Florida's Construction Industry Licensing Board, and a permit for changeouts.
Tips before you hire
- Get a load calculation (Manual J) instead of simply matching the old tonnage. Oversized systems short-cycle and leave Florida homes clammy.
- Ask whether the quote includes the permit, a new pad and disconnect, and code-required updates.
- Plan replacements for spring or fall. Summer emergencies cost more and wait longer.

Frequently asked questions
How long does an AC system last in Florida?
Heavy use and humidity mean many Florida systems need replacing sooner than in milder climates. Coastal salt air can shorten that further.
Does an AC replacement need a permit in Pinellas?
Yes. A changeout typically needs a mechanical permit, and the contractor normally pulls it.
