How long you should keep your air conditioner turned off depends entirely on the specific maintenance task or issue you are addressing. If you have simply turned it off via the thermostat to reset the system, clear a minor glitch, or let frozen coils thaw out, you should typically leave it off for at least 30 to 60 minutes to ensure complete ice melting and internal pressure equalization. However, if you are performing heavy repairs, clearing severe clogs, or waiting for a professional technician to arrive, you should keep the unit completely powered down at both the thermostat and the main circuit breaker until all repairs are fully completed and tested.
