AC Runs Constantly in Tallahassee, FLTop causes, real repair costs, when to replace instead
An AC that runs 24/7 and still can't hit the thermostat setpoint usually means undersized equipment, a refrigerant leak, or failing components. In Florida's 92°F summer afternoons, even a healthy system runs most of the day — but it should still cycle off. If it never cycles, something's wrong.

Undersized system
Common when a homeowner added square footage without upgrading HVAC. Only fix is right-sizing with a replacement.
Refrigerant leak
