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.
