My house didn&#x27;t play nicely with my Nest. I got a new Furnace and AC and had them install a Nest. It started acting weird. We replaced it with a low-tech Honeywell while trying to get it figured out. I then replaced the Nest thinking maybe it was faulty. I took a photo of the wire layout for the Honeywell and made sure I did the proper layout for the new Nest. It worked fine for a few days and then one day I came home to a 110 degree house! The Nest reported that things were 70-whatever. I then replaced it with a Wi-Fi Honeywell (not their Nest competitor) and that one has worked fine since. It was a very scary experience. I won&#x27;t be trying a Nest again.
