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

Start with quick checks. Confirm the thermostat is set to Heat and above room temperature. Replace thermostat batteries. Make sure the furnace switch is on and the breaker hasn’t tripped. Check or replace a dirty air filter. If you have a reset button on the furnace, press it once.

Quick checks:

• Clean/replace filter
• Try one furnace reset
