Repairs Your Furnace May Need

Furnace repairs are some of the most common kinds of heating repairs in the country, purely because they happen to be the most common kind of heating system on the market. As they are the most common heating systems available, it stands to reason that you are one of the many homeowners that use one. It’s always a good idea to know some of the vulnerabilities that your heating system has to certain issues. With that in mind, let’s look at some of the more common repairs that your furnace will need.

Broken Air Handler

The air handler is the collection of parts that is responsible for circulating warm air throughout the house. It is comprised of two main parts, the motor and the fan. Older systems also included a rubber loop called a “fan belt,” though this has since been phased out. The most common air handler issue has to do with the motor itself.

The air handler motor is equipped with several lubricated bearings, designed to keep it running smoothly and with as little friction as possible. These bearings can dry out over time, slowly increasing the friction on the motor during operation. Eventually, the motor has to take on so much extra strain without the bearings that it burns itself out. If you hear a grinding sound coming from your furnace, that’s the sound of the bearings wearing down. You should call a professional to examine it as soon as possible.

Malfunctioning Thermostat

A malfunctioning thermostat can affect the entire furnace system, owing to the central nature that it plays. The thermostat is the core control for any heating system, and without it the furnace just won’t work. An easy way to identify a malfunctioning thermostat is simply to check the display. If everything is displaying correctly, including the settings and temperature, then the thermostat is likely doing fine. If the temperature is off, or the thermostat isn’t responding, then you likely have an issue with the sensor or control boards. It is also possible for a thermostat to appear fine, but fail to reach the furnace because of a loose or severed electrical connection between them.
