STEP 1
Power o 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.
STEP 2
Confirm your system is o 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.
