First hang your thermo next to the sensor(s). Thats where your thermostat is getting the temp readings from. My guess with the air flow problem is that you have a disconnected duct or duct(s), mine did that. As for the heat pump that is what its supposed to do. It is de-icing the compressor. Hope this helps stay warm. Its been in the low 30's where Im at right now and the HP and 2 small space heaters are keeping the MS warm.
