Is HVAC device a heat pump?
The model number provided is an air handler. The "heat package" shown in your picture is a electric element heating which may or may not be installed(was not factory installed). The unit shipped with a evaporator coil installed as per the rating plate, but that didn't come charged with refrigerant. An air handler is capable of running a heat pump. The simplest way to tell if it's a heat pump is the model of the outdoor unit, without easy access to the condenser (if it's on a roof or something) check how many wires go to it from the air. Usually 2 wires go to a cooling only condenser. Sometimes 2 stage applications or onboard diagnostic require more wires. Never assume the color of the wire to correspond to any standard practice. I'm leaning towards no heat pump due to the TXV shipped with the coil. Heat pumps with TXV either need dual TXVs or a bypass check valve when reversed flow is happening. There may be some new methods being used in the southern states that I'm unaware of. I'm from Toronto and don't often deal with heat pumps as our electricity is very expensive.
