The unit worked nicely during the summer. I was told at the time of installation that no maintenance was required and to just switch the thermostat to "heat" in the winter. Well, I did that, and the furnace came on, but the outside compressor also came on. I called the installer who checked it out and said I needed to pull out the fuse on the outside electrical disconnect and set it in the "off" position.
I have talked to other homeowners, and none have to do this. Is it normal, or should I call the installers back?
Also, with the A/C install, they replaced the thermostat. The furnace is a two-speed model. The thermostat is a single stage heat/cool thermostat. Am I losing the two-speed benefits of the furnace? Should I ask for a new thermostat?
