Any of you guys have the Nest heating/cooling thermostat? Just installed one for my upstairs area today and just looking for some feedback. I know next to nothing about HVAC and I have gas heat with heat pumps for AC so wiring the unit was a chore. They (nest) suggest professional installation when you have two sources of heating/cooling like I do but my pride wouldn't allow me to do that. Hopefully did it right lol....
