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.

02Top Causes

Why ac runs constantly happens in North FL homes

In order of frequency based on thousands of service calls in the North FL region — the most common issues first. Your Tallahassee technician will diagnose the real cause in under 30 minutes.

01

Undersized system

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

02

Refrigerant leak

System can't reach setpoint because it's under-charged. Leak + recharge: $400–$1,100.

03

Dirty condenser coil

Cannot reject heat. Coil wash: $180–$300.

04

Failing compressor

Compressor can't pull the system down to setpoint anymore. On 10+ year old units, replacement beats repair.
