They came back today, board this time is fine, but the Nest still wouldn’t work. I have up and agreed to a different thermostat. They hook it up, test all functions, everything works. We could again turn on the heat, fan, and AC from the thermostat they put in.
Then they leave, and the AC won’t come on. Furnace and fan work fine, no AC. Obviously it isn’t needed right now, but I’m still pissed. Time to get on the phone with them for the umpteenth time in the last week.
