    Default Heat Pump?

    Freddie Mac foreclosure with exterior heat pump, York M # YHJD42S41S7A. Thermostat had settings for only heat and cool. When heat set, a high efficiency furnace provided heat, and on cool setting, the heat pump was operational but did not produce cold air. Wondering if this was a wrong install as this was installed after foreclosure process initiated. Also, can heat pump be wired only cooling?

    Sidney, sorry I do not do foreclosures.

    1: Did the serial numbers on the compressor?

    The year on manufacturing is 1979 2000 but the fourth letter, # YHJ(D)42S41S7A
    does not match the literature on Building Intelligence Center.

    Heat Pumps life expectancy is 15 years.

    Hope that helps.

    I would write what I observed.

    It was manufactured in Wichita November 2015.

    I bet in the wrong hands it can do more than that.

    I forgot to ask, was the thermostat set to emergency heat?

    Sidney,

    A heat pump is, basically, just an air conditioning system wit a reversing valve which reverses the direction of refrigerant flow: a) cooling uses the indoor coil as the evaporator coil and the outdoor coil as the condenser coil - this transfer heat from inside to outside; b) heating uses the indoor coil as the evaporator coil and the outdoor coil as the condenser coil - this transfers heat from outside to inside.

    If the unit was wired incorrectly, the thermostat wired incorrect, an incorrect thermostat installed, etc, a heat pump could be wired to 'only heat' or 'only cool'.

    Heat pumps typically also have a back up heat strip, thus the thermostat will have an emergency heat setting which allows just the heat strip to operate.

    I may be possible to wire it so the emergency heat strip turns on when in cooling mode - which could produce nothing positive (no heating and no cooling).

    As stated in the original post, there was no emergency heat setting on the thermostat.

    I can read what you said but did not see what was there.
    Also, I am not here to get it in the neck.
    So where did you indicate there was no EM HEAT?

    Please read Jerry's answer.

    Hope that helps.
    Have a great day.

    If you only knew how many strange looks I get when I say that.

    High efficiency heat, I am thinking gas heat. While there are dual fuel heat pumps, they will still have Emergency Heat setting on thermostat.
    This could be just a gas pak standard HVAC unit. Heat and Cool on thermostat.
    The fact that is wasn't getting cold air is another matter. Did compressor kick in?
