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

Try a few safe checks first, then call our 24/7 team if heat still won’t come on. Set the thermostat to Heat and at least 68 F, and replace its batteries. Make sure the furnace switch is on and the breaker isn’t tripped. Replace a clogged air filter and open supply/return vents. If you use gas, confirm the gas valve is open. Clear snow or debris from outdoor intake and exhaust pipes. Harker services furnaces, boilers, heat pumps, and ductless systems in Madison.
