How to set up a smart thermostat to save energy?

Most smart thermostats are designed for DIY installation in under 30 minutes. Turn off your HVAC system at the breaker. Remove the old thermostat faceplate, photograph the wiring, and label each wire. Mount the new base plate, connect wires to the matching terminals, and attach the thermostat.…

After installation, manually adjust the temperature for the first 1-2 weeks as you normally would. Smart thermostats like Nest learn your patterns — when you wake up, leave for work, return home, and go to bed — and automatically create a schedule. You can also set schedules manually in the app.

Many utility companies offer rebates of $50-100 for purchasing a qualifying smart thermostat. Some utilities provide smart thermostats for free or at deep discounts through energy efficiency programs. Check your utility's website before purchasing.

Place wireless temperature sensors in the rooms you use most. Ecobee SmartSensors ($40 each, one included) and Nest Temperature Sensors ($25-40) report each room's temperature to the thermostat, which adjusts to prioritize comfort where you actually are.

If your system lacks a C-wire, uses a multi-stage heat pump, or has unusual wiring, hire an HVAC professional. They can add a C-wire, verify compatibility, and ensure the thermostat is configured correctly for your specific system. Typical installation cost is $75-150.
