    Look in the top past the fan blade. If you see a reversing valve, i would have to say yup heat pump.

    Since I start indoors (checking filter and such), I check the thermostat...
    ...EM Heat, AUX Heat, or two stage heat as indicated with two mercury switches are good indications that I have a heat pump system.

    If you look at a HP they usually are up off the pad several inches to feet depending on the dealer. A/Cs are generally setting right on the pad. Not always but in general it seems to hold.

    Maybe down south they don't elevate heat pumps ? Up here the deforst water would back up because the unit would be in snow. The FEW heat pumps that we were forced to sell were alway put at least 1 foot above the ground level.

    Look for 3 hose connections at the outdoor unit. Liquid line, vapor line and common suction.
