Before you call for repair, a few quick checks can sometimes get the heat back on — or at least help us diagnose the problem faster.

• Check that the thermostat is set to heat and above room temperature

• Replace the thermostat batteries

• Make sure the furnace switch and breaker are on

• Check that the filter isn’t completely clogged

• Confirm the gas supply valve is open

If none of these work, or if you smell gas or hear a carbon monoxide alarm, leave the house and call us right away. Our emergency line is open 24/7.
