STEP 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.
TIP Look for your master switch or circuit breaker box in the basement,
attic, utility closet, or behind a wall panel near the thermostat.
TIP If you have a boiler, check to see that the main flame is extinguished.
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.
STEP 2
STEP 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.
