I moved into a new house this past December. I noticed during the winter that the house would sometimes feel rather too cold than I thought it should given the thermostat setting. This week I tried to turn on A/C for the first time and the compressor outside doesn't even start up.
I looked up the control panel installed and it is a Honeywell HZ311, which is a 1H/1C panel. My furnace is definitely a 2 stage heater. Would this explain why the house sometimes felt cold during the winter? Could this the reason the A/C isn't working, or there is something else going on there?
Should I be replacing the existing panel with a more compatible model right away?
Thanks in advance!
