Many people know they need to call a heating repair contractor if their heater stops working. But what you may not realize is that there are other small problems your heating system may develop over the years. If you remain on the lookout for these small problems, you can call an HVAC contractor about them. In doing so, you may protect yourself from dealing with bigger heating issues down the road. Here are some smaller problems you really should call your heating contractor about.

Your home is not getting to the set thermostat temperature.

If you set the thermostat to 75 degrees, your home should heat to 75 degrees. If you set it to 73 degrees, it should heat to 73 degrees. If your home is always struggling to reach the setting on your thermostat, this is something you need to call the heating contractor about. There may be something wrong with the connection between your furnace and the thermostat. Or, there may be something wrong with the furnace, which is causing it to generate less heat than it should be generating. 

Clicking or banging noises.

Your furnace really should operate quietly. If you are hearing clicking or banging noises, either when the furnace turns on or throughout the heating cycle, this is not normal. There may be a loose component somewhere in the furnace. It may not be affecting the furnace's operation right now, but it will eventually. It is best to have an HVAC contractor take a look and make repairs before the problem becomes any bigger.

A yellow pilot light.

The pilot light in your furnace should be blue. This means that it is hot — an ideal temperature to light the burner and generate heat. If you look at the pilot light and find that it is yellow or orange rather than blue, this is a problem. The flame is not getting enough gas. This could be because of a blockage in the gas line. It could also be because the burner is dirty or a valve is faulty. A heating repair contractor will fix the issue before it leads to a loss of heat.

These heating issues may seem minor at first because your home is still warm, but they do eventually get worse. The beauty of recognizing them early is that it gives you a chance to fix them before you have to go without heat.
