ST E P 1 Power off your Heating, Ventilation, and Air Conditioning (HVAC) system by using the master switch or circuit breaker box. This is important for your safety. ON OFF ON OFF TIP Look for your master switch or circuit breaker box in the basement, attic, utility closet, or behind a wall panel near the thermostat.
STEP 2 Confirm your system is off by turning on your heat (during winter) or your AC (during summer). Wait a few minutes—you should not feel air coming from your vents. TIP If you have a boiler, check to see that the main flame is extinguished.
ST E P 3 Remove your old thermostat cover from the wall. TIP Many thermostats simply pop off or unclip from the base, while others may have screws that you will need to remove.
