Any HVAC experts?

If it's running, it probably means the compressor is running as well, which means your A/C is effectively ON.

That is what I thought, but when I went to the registers it was blowing warm air not cold air and the thermostat was set to off. As soon as I turned off the air exchanger the fan stopped turning on the a/c unit. Since then I have had the a/c on and it blows cold air just fine. I am at a loss. Maybe I will go turn the thermostat to heat and see if the air exchanger still turns on the a/c unit.
