Check the Breaker First
You turn the thermostat to cool, but nothing happens. No click. No hum. Total silence. Before you panic, check your electrical panel. Look for a tripped breaker. Sometimes a power surge will knock the AC offline. Flip the breaker completely off, wait a second, then flip it firmly back on. If it trips immediately again, leave it alone. You have a short circuit.
Thermostat Trouble
Next, look at your thermostat. Blank screens usually mean dead batteries. Pull the faceplate off and swap in fresh AAs. If your thermostat is hardwired to the house and the screen is dead, the indoor furnace might have blown a low-voltage fuse.
The Hidden Drain Switch
Our Ohio River Valley humidity creates gallons of condensation inside your indoor unit. If the PVC drain line gets clogged with algae or sludge, water backs up. A safety float switch will detect this water and shut the whole system down so it does not flood your floor. Older homes in Newtown and Amelia often have long drain lines routed in strange ways that clog easily.
Electrical Faults
If clearing the drain and checking the breaker does not work, give us a call. We will come out for our $89 diagnostic fee to test the low-voltage wiring. We always use a Repairs First policy. We find the broken wire, fix the bad contactor, or clear the clogged pipe. Honest work without the heavy sales pitch.
