Hi I'm Brian and I'm here to help!

What is the specific issue you'd like help with regarding your thermostat replacement? If it's initial wiring, please tell me what color wires went to what lettered terminals on the old thermostat and I'll help you get your Nest set up properly. I'll also need to know what type system you have, e.g. Furnace with ac, Heat pump with electric heat backup, ac with electric heat etc...
