Expert Oil Furnace Repair in San Antonio

Furnace balking at starting? Reset button keeps tripping? If your fuel oil furnace is leaving you irritated and chilly in San Antonio, the Experts at San Antonio Air Service Experts can help.

Sometimes, you can take care of troubles with your oil-burning furnace alone. There are several things you can take a look at before getting in touch with us for heating repair.

Common Oil Heating System Problems

  • Furnace won’t start. The thermostat setting may be incorrect. Check that it’s set to “auto” and “heat.”
  • Reset button keeps tripping. This safety feature stops your furnace when it spots an issue. Make sure there’s fuel in the oil tank, the valves are open and the chimney is unobstructed. Once you’ve checked those areas, only press the reset button once. Pressing it too many times could cause fuel oil to accumulate and spark a fire once the furnace begins working.
  • Inadequate heat. The oil or air filters could be clogged and need to be cleaned or replaced.
  • Excess noise. If you hear clattering, tighten access panels. Squealing means there’s a problem with the belt or blower motor. If these components have oiling ports, put a few drops of electric motor oil on them after shutting down your furnace.

Other times, you’ll need one of our professional service technicians. Call San Antonio Air Service Experts for oil furnace repair service when:

  • Using the reset button doesn’t start the furnace, even when there’s fuel in the tank and valves are open
  • You hear knocking sounds, which likely signals there’s air in the fuel lines
  • Oil lines are leaking
  • Soot can be seen in the burner chamber
  • Burner works but does not fire
  • Previously mentioned troubleshooting suggestions don’t fix the problem
