Take control of your thermostat.


Meet the Nest Learning Thermostat.
It learns what temperatures you like, turns itself down when you’re away
and connects to your phone. It has a big, sharp display. And it’s proven
to help save energy. In independent studies, the Nest Thermostat saved
an average of 10% to 12% on heating bills and 15% on cooling bills.
Nest is estimating an average savings of $131 to $145 a year.
