Install a Smart Thermostat

⏱️30 min💰$80–250🟢Beginner4.8 (523 reviews)

Save 10–15% on heating/cooling with a programmable thermostat. Most installs are 30 minutes.

Turn off power at the breaker

Find the breaker labeled "furnace" or "HVAC" and flip it off.

Remove the old thermostat

Pull off the faceplate, then unscrew the backplate. Photograph the wiring before disconnecting.

Check for a C-wire

Most smart thermostats need a "common" wire. If you don't have one, use the included adapter or contact the manufacturer for help.

Mount the new backplate

Thread wires through and screw to the wall. Use the included level if your wall isn't perfectly flat.

Wire to the new thermostat

Match each wire to the labeled terminal (R, W, Y, G, C) following your photo and the new thermostat's diagram.

Snap on and set up

Restore power and follow the on-screen setup. Connect to Wi-Fi and your phone app.
