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

If your heater isn’t working, try a few safe checks, then schedule service if it still won’t heat. Set the thermostat to Heat and raise the setpoint. Replace a dirty filter. Make sure the furnace or air-handler breaker is on. For gas units, confirm the gas valve is open and note any ignition or pilot issues. For heat pumps, clear debris from the outdoor unit. If you smell gas or burning, turn the system off and call us. Same-day service is available in the San Antonio area.
