I have verbiage that states that the outside temperature is to low
to test AC system. ( to turn on from the thermostat) Does anybody
know the reasoning behind that disclosure ?

A/C (not heat pumps) are not set up to run in cold temps.
For a compressor to be efficient, there must be little clearance between the compressor piston and the head. Any liquid getting in there will break a valve or crankshaft.
If you do run it in the cold, It wont run right for you to tell anything but that it runs.
It can be modified to operate in the cold (by an HVAC engineer) so it can be tested, but you can’t.
Thanks
Hope that helped.
Had to be brief, leaving for work…
Thanks for the very detailed explanation. I have had the same question.
