In order of frequency based on thousands of service calls in the SW FL region — the most common issues first. Your Cape Coral technician will diagnose the real cause in under 30 minutes.
Tripped breaker
Single-pole or 2-pole breaker for the air handler and/or condenser. Reset once. If it trips again, stop — you have a short.
Dead thermostat batteries
Most thermostats run on 2 AA batteries. Swap them. Free.
Blown low-voltage transformer
No 24V to the thermostat means nothing turns on. Transformer replacement: $180–$400.
