Steps To Take When Undertaking Your Own Furnace Repair

A furnace is an intricate and expensive part of your home.  The cost and hassle involved in fitting these systems often means that people stick with an original system and carefully nursemaid it to ensure it continues to function properly.  However, it is possible to replace parts and even the whole furnace without too much inconvenience providing you follow a set of procedures designed to ensure your replacement furnace slots straight into the place of the old one.

Unfortunately these types of appliances always break when they are needed the most!  You will find that a repair person is suddenly difficult to find as they are all busy and can’t visit your house for three or four days.  This can be true even for excellent services like Smile Heating & Cooling.  At this point it is likely that you will consider your own furnace repair rather than wait for the repair person to be free.

Although there are elements of your furnace which you should not open the process of undertaking a furnace repair is not excessively difficult.  The following steps can all be completed by the amateur DIY person:

False Off

The furnace can sometimes switch off or refuse to start if the thermostat has become temporarily stuck.  To check this you should turn the thermostat down as low as possible.  Your furnace should now know that it is off.  Next turn the thermostat up.  As soon as you hear a click; stop.  This means the furnace should fire up; it will be obvious by the sound of the fan running.  If this happens, then you have probably discovered the issue.  Turn the thermostat up slowly to see if it affects the fan at any point.

The Pilot

Your furnace will have a pilot light.  This must be lit so that when the furnace needs to apply heat it can ignite the gas or oil.  Without a pilot light there is no ignition and no heat can be created.  If the light is out you should either be able to light it by hand or follow the instructions written near it to get it started.


A furnace has an air filter.  This prevents debris from getting into the fire and disrupting the air flow.  It also allows the air from the home to enter the furnace via a thermostat.  If the air is considered warm enough then it shuts off the furnace; assuming the room or house has reached temperature.  A blocked filter can restrict the air flow to the furnace; either convincing it that the room is already warm enough or simply stopping the air from getting to the fire.  Cleaning the air filter with a dust cloth or even some warm water can release the blockages and allow air through to the furnace.

Air Supply

Just as the filter can prevent air from getting into the furnace, you can also get a blockage in the intake pipe which is usually outside your house.  If it is blocked your furnace will not be able to sustain a fire and the heat will stop.
