With having your furnace repaired there are many different costs. Having diagnostics done to determine what is going wrong will cost you a fee, not including how much the furnace repair costs. Diagnostic fees vary greatly from heating company to heating company. However, many professional heating companies will waive the diagnostic fee if you go ahead with the repair on the same day.

To guarantee that you do not pay a big lump sum in repair costs, make sure the maintenance is properly checked out every year, so the basic functioning of the furnace is working correctly. The cost of a furnace cleaning and service starts at $125 and goes up for there. Remember that furnace service and maintenance is always cheaper then having repairs done.

Here are some examples of things that could go wrong with your furnace:

• Your furnace may not be putting out any heat.
• Pilot light might go out.
• There could be a time, your pilot light refuses to light.
• The thermocouple may not working properly.
• There may be a problem with your fan, causing your furnace to make noises.

Here is a list of things that may to be replaced or worked on. The cost of fixing these problems can range from $125- $1,500:

• Circuit board
• Emergency Shut Off Stair Switch is Off
• Filter Door Not Back on Properly
• Combustion blower

Those furnace repair costs are prices of professional heating companies coming out to your home and fixing the problem, not including the diagnostic fee, if the heating company does not waive it.  Some of these problems could very easily be fixed on your own, with just the right know-how.
