Save this for the first time your heat won't come on. Four things to check before you call anyone:
1. Thermostat: set to HEAT, a few degrees above the room, fresh batteries.
2. Power: the switch by the furnace or boiler is on (it looks like a light switch), and the breaker hasn't tripped.
3. Filter: a clogged furnace filter can shut the system down.
4. Fuel: oil tank not empty, gas turned on.
Smell gas? Leave the house and call your gas company or 911 from outside.
Still no heat after all four? Call us: (978) 957-2728
