What Should I Do If My Heater Is Not Working in My House?

Check the thermostat, filter, power, and gas supply first. If those are fine and the heater still won’t run, schedule service so a technician can diagnose and repair it.

• Set thermostat to Heat and 3 to 5°F above room temp.
• Replace a dirty filter.
• Verify the furnace switch and breaker are on.
• If you smell gas or suspect CO, exit and call for help.
