Yes both are on the generator, or at least can be. Up till now I turn the breakers off for the upstairs unit if I am on generator power. When we have lost power in the summer I just turn both off. sweating is uncomfortable but you won't freeze to death. its a 10kw unit and is admittedly a bit undersized but a new one is several thousand. it will start the larger downstairs unit but takes a noticeable hit when it does. What I am wondering is if the soft/slow start will ramp it up more slowly.

Where the lines enter the indoor coil the line in temp is about 130f and outlet line temp is 80 when outdoor temp is 17 or over. Under 17 it drops a little. It was 8 this morning and inlet was 124f at the coil. Roly
yes I have aux heat. the thermostat said it was calling for aux heat, so I dunno.
