We had our furnace replaced a few years ago and now want to move our thermostat. It's against a cold outer wall, and runs our furnace more based on the outside temperature than the inside temperature.
The thermostat is the type that runs on batteries. There's no power wire - something we didn't know when we had the furnace replaced. So, I need to have some wiring done to get it moved and hooked up correctly. Who would I call to do this? A plumber who does heating/cooling or an electrician?
