Your AC won't turn on at all — silent, no fan, no clicking, nothing. Before assuming the worst, run through these 7 checks in order. About 60% of 'AC won't turn on' calls are fixed in under 30 minutes for under $300. The rest involve more serious repairs we'll handle same-day.
⚠️ Do not repeatedly reset a tripped breaker. If a breaker trips twice in a row, there's a real electrical fault — keep flipping it and you risk a fire. Call us.
Battery-powered thermostats need batteries replaced every 12–24 months. Symptoms: blank screen, no display, no clicking when you change settings. Try fresh batteries first — most common 'AC won't turn on' fix.
AC tripping a breaker is a symptom, not a cause. Reset it ONCE. If it trips again, there's an electrical fault (short, failed capacitor, motor windings burning out, ground fault). DO NOT keep resetting — call us.
The metal box next to your outdoor AC unit holds a fuse or pull-out disconnect. Power surges (lightning, brownouts) blow these. We test and replace in 10 minutes.
If you hear a humming sound when the AC tries to start but the fan doesn't spin, the capacitor is dying. #1 cause of mid-summer breakdowns in Florida.
The contactor is an electrical switch that turns the compressor on. When contacts burn out, the AC can't start. Symptoms: clicking sound but no run, or no clicking at all.
Modern systems shut down completely when the drain pan overflows. If your AC just suddenly stopped working (no warning) and you see water around the indoor unit — float switch.
If everything else checks out and the compressor still won't start, it's likely the compressor or motor itself. Older systems (10+ years) often justify replacement over repair.
Run through these in order — about 30% of calls are resolved by the homeowner with these checks.
Lit up? Move to next step. Blank? Replace batteries (most are AA or AAA). Wait 30 seconds and test.
Any breakers half-tripped or fully off? Push fully OFF, then back ON. If the AC breaker trips again — stop, call us.
Metal box next to outdoor AC. Some have a pull-out fuse — make sure it's IN, not pulled out. Don't open the box yourself if not comfortable — 220V is dangerous.
Try turning the AC on at the thermostat. Walk outside. Do you hear humming? Clicking? Total silence? Each sound points to a different problem (capacitor, contactor, no power).
Indoor unit usually has a small float switch on the drain pan. If the pan is full of water, the switch shuts everything down. Empty the pan, clear the drain (vinegar), and try again.

Usually a failed capacitor. The click is the contactor closing, but without the capacitor the motor can't spin. $165–$295 fix, typically done in 20 minutes.
