How much can a smart thermostat actually save?

ENERGY STAR estimates 8 percent savings from a basic programmable thermostat. Smart thermostats with occupancy detection and learning add another 5-15 percent on top of that for total savings of 15-25 percent.

Can I install a smart thermostat myself?

Most installations take 30-45 minutes with basic tools. The biggest requirement is a C-wire for power. If your current thermostat has 4-5 wires, you likely have one. Some models include an adapter if you don't.
