Try this...
Sneak up on it and see if you can catch it while it is performing this mysterious heating mode.
If you come in and you think that your house has moved next door to the depths of H E L L, fist go look at the condensing unit and see if 1. The compressor is running. If the condensing fan is running and the compressor is not, the chances are good that it is off on an internal overload or inherent protection device.
This may or may not be a bad thing. It may be tight cycling and the compressor may not be starting against pressure very well. A simple delay on break timer may take care of this problem.
It may be the start capacitor and relay may not be functioning correctly.
If the compressor is running along with the condensing fan motor, see if the unit is in the heat pump mode. Feel the line set going to the evaporator and see if one of them (large one) is hot. May be a control problem.
When it is running and cooling check the temperature of the bigger line back to the compressor. It should be cool/cold.
Start with this and let us know.
