How Can I Reset My Air Conditioner to Fix Power Issues?

To reset an air conditioner after a power issue, turn the thermostat to Off, reset the AC breaker once, wait 5–10 minutes, then turn cooling back on. Most power problems trip a circuit breaker or a safety that protects the compressor from short-cycling. Our technicians see this often in Georgetown homes after storms or brownouts, and a careful reset usually restores normal cooling. If the system won't restart or trips again, that points to a failing part and needs service. We also offer 24/7 emergency repairs when a reset won't hold.

Try these steps in order:

• Set thermostat to Off; set fan to Auto.
• Reset the dedicated AC breaker once; do not keep flipping it.
• Confirm the furnace/air-handler switch (looks like a light switch) is On.
• After 5–10 minutes, set thermostat to Cool and a few degrees lower to test.

Stop and call a pro if you smell burning, see smoke, or the breaker trips again.
