Cool my training books are coming in handy. Following are what it says:
1.) Look at the data plate, either Heat Pump or HP at start of model number–you got that one!
2.)If the thermostat has an Emergency Heat setting–you got that one too!
3.) Take the cover off the thermostat and if it is a two stage thermostat then it is a heat pump.
4.) If both Freon lines are insulated then it is a heat pump
5.)If you open the condenser cabinet and there is a reversing valve it is a heat pump
6.) If you find two expansion devices with bypasses it is a heat pump
7.)If the compressor is indoors and it is an air to air system, it is a heat pump
8.) If there is an outdoor thermostat connected to the wiring it is probably a heat pump
9.) You will like this one!—If it is winter and the unit is operating, it is a heat pump!!!
