if it's not a heat pump it won't matter. But why would you turn it off anyway?

Presumably the idea is to save the few cents of power used by the compressor's crankcase heater.

Why would the ODU care? It's not a living entity.

If it is just an ac then it very well may not matter. Most typical outside ac units do not use any power if the contactor is not engaged.

Turning it off would save a small ammount of energy for the crankcase heater (typically 54 watts). If you turn it off, please turn the power back on at least a full day before you use the AC, two days is better. Othewise, compressor damage can occur.

A non living compressor can collect refrigerant in with the oil.

There better be oil in the refrigerant.

i'm sure the installers don't wait two days to fire up a new install.

I never did. How the hell would you check for leaks/proper operation before you left the job? I sure didn't have the time to come back two days later to fire up a system and my customers wanted their home cooled ASAP.

Makes sense, to me. Might be an issue only in cold weather.
