Doug, if you still live in LI, chances are you don't have a heatpump, so it sounds like cooling and heating is running at the same time.
But if you live in Texas, that could very well be a hp, the compressor runs in heating and cooling mode and there won't be as high a discharge temp as with a gas fired unit.
First I think you need to find out if you have a hp or not.
good luck
