Help with heat pump!!

mike85rob

Okay, we bought a home a couple of years ago with a central air unit (do not know if it has a heat pump or not). The previous owners used it as a summer house and probably did not need heat. Here's what we have and what happens.

A/C works good
We have to use $Emergency Heat$ in the winter. When I turn on the regular heat switch the fan blows but it is cold air. It does not feel like the a/c but rather just air that is the temp of the air outside. Inside the thermostat the O wire is not hooked up but is present. Outside I cannot remmber what is hooked up with what because I am writing this at 2 in the morn and I may check this tomorrow if the rain holds off.

So what I need to know is do I have a heat pump or how can I tell?

a note on my above post. Do not assume that whoever hooked the system knew what they were doing. I am not very experienced in hvac but I am with elecrical and lets just say that when we bought the place I had to do a lot with the electric to bring it up to code.

Get the model number of the unit and then look it up on the manufacturer's website or post it here.

Or pull the cover and look for the presense of a reversing valve. Do this with the breakers off to be safe.
