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

If your heater stops working, try a few quick checks, then call Appleton Campbell for rapid local heating repairs. We service Ashburn, Warrenton, and nearby, and work on furnaces, boilers, heat pumps, and ductless systems.

• Set thermostat to Heat and 68–72 F; replace batteries.
• Check the breaker and furnace switch are on.
• Replace a clogged air filter.
• Gas furnace: relight only if you know how; if you smell gas, leave and call your utility.
• Heat pump: clear snow/ice from the outdoor unit.
• Note any error codes or unusual noises.
