Teach Nest to save.
Programming thermostats is complicated and irritating - but an un-programmed thermostat can waste 20% of your heating and cooling bill. So the Nest Thermostat programs itself. Just turn it up and turn it down. The Nest Thermostat learns what temperatures you like and builds a personalized schedule. Teach it efficient temperatures for a few days and, within a week, it'll start setting them on its own.
