Does switching an AC on and off save electricity, or is it better to leave it running?

For an inverter AC, leaving it running at a steady set temperature is generally more efficient than switching it off and on repeatedly — restarting means the compressor briefly draws more power to ramp back up, and the room needs to be re-cooled from a warmer starting point each time.

This is the inverse of the common assumption people carry over from non-inverter ACs, where cycling on/off is literally how the unit already operates. An inverter AC left running continuously at a held temperature avoids that repeated ramp-up cost — see our page on why the compressor keeps running for more on why continuous low-speed operation is the efficient mode, not a fault.
