a/c
turn off the breaker for the a/c unit in the off season for a hydro savings also electric stove breaker while on holidays etc.:)

Any idea how much energy the A/C system pulls while not in use?

Some A/C's run a Crankcase heater on the compressor that can draw from 40-100w to keep the oil warm(forgot where I read that). This matters if you plan on running the A/C, but if it's going to sit idle for the next 6 months, no point in keeping it warm.

Older Sanyo Mini-splits cool&heat units have the Crankcase heater on the compressor, if the unit is 24k BTUh and above.
Not sure about the AC (cool only) models. I don't think they even need it. Especially since they are turned on when it's already pretty warm outside anyways. :) I've noticed mine use about 40W each (I have two units), but they seem to be temperature controlled. If it's cold night followed by a warm day, I'll check the TED and sometimes, I'll see Zero watts displayed.:D But, even without the crankcase heater on, there is still the electronics loads of the controller boards in the indoor and outdoor units. My guess is a few watts at the most. Can't see that low on the TED. |
Most residential central AC units do not have crankcase heaters. Zero power used when turned off.
