Gas heating FAQ

Q My furnace won’t come on.  What can I check before calling for furnace repair? 

A  Make sure that the thermostat is set in the heating mode and that the set point is warmer then the room temperature.  Make sure that the furnace disconnect switch is on and that the circuit breaker is on.

Q  The burner on my furnace won’t light.  Could the problem just be that my pilot needs to be lit?

A  Unless your furnace is either over 20 years old or is a mobile home specific unit,  it probably does not have a standing pilot that needs to remain lit.  If your furnace does have a standing pilot,  there should be lighting instructions on the front of the furnace.  Newer furnaces have either direct or indirect automatic ignition systems.  The ignitor is either hot surface or spark.  On hot surface ignition systems,  the ignitor is the weak link.  On spark ignition systems,  the spark module or integrated control is the weak link.

The burner on my furnace lights and then goes out a few seconds later.  What causes this.

A  Most modern furnaces use AC to DC flame rectification prove to the controller that a flame is present.  If controller does not read a DC  microamps signal from the flame sensor, the controller will think that the burner has failed to light.  The controller will shut of the gas valve to prevent dumping unburnt gas.  Common causes are dirty burners or flame sensor,  poor electrical ground or faulty controller.

Q  Is it a good idea to have a CO detector in my house.

A  It  is generally a good idea to have a device to alert when a potentially dangerous condition exists.  However most commonly available CO detectors will not alert on low level CO conditions and they may offer a false sense of security.  The UL standard for CO monitors is designed to protect health adults from from large amounts of CO and fails to alert on low level CO that may have serious health consequences for some persons.   Singer Heating and Cooling is equiped with test instruments to detect CO in your home but,  at this time,  we do not sell CO monitors.  For your benefit click here to learn more about low level CO monitors.

Q What causes CO and how can CO enter my home?

A  CO is produced by incomplete combustion of fuel.  Perfect combustion only occurs in theory but a properly operating furnace produces little CO,  and that CO is vented to the outdoors.  A furnace that is not operating correctly can potentially produce hi levels of CO.

Q  I Smell a strong gas odor inside my home or business.  What should I do?

  • Get everyone out of the building immediately.
  • Leave the door open.
  • Use a neighbor’s phone or cellular phone outside of the building to call your gas supplier or local fire department.
  • DO NOT operate any electrical switches, appliance controls, or pull any plugs from outlets.
  • DO NOT use the telephone in the building.
  • Close the cut-off valve near the gas meter and DO NOT turn it on again.
