Causes Of A Broken Furnace

The average furnace can last for 10 to 20 years. However, you will likely need to get furnace repair long before the 10-year-mark. A technician will have to identify the cause of the furnace problem in order for it to be repaired properly. There are several things that can cause your furnace to break down.


Dirt build-up is one of the leading causes of furnace failure. The filter is supposed to trap dirt. It prevents the dirt from being circulated throughout your home. Your filter needs to be changed at least once a month. If your filter is dirty, then it will cause your furnace to work harder. That is why it will eventually break down.

Electrical or Gas Issues

In some cases, a gas or electrical problem can cause your furnace to malfunction. Working with gas or electricity can be dangerous. That is why you do not want to handle this problem by yourself. You will need to contact a professional if your furnace has a gas or electrical problem.

Normal Wear and Tear

Your furnace works hard to warm your home. It is subjected to a lot of wear and tear. That is why it is important to get regular maintenance. A HVAC professional will ensure all of the parts are working properly. In many cases, furnace problems are caused by a lack of maintenance.

Broken Bearings, Belts and Motor

Your furnace may break down if there are problems with the components inside of the furnace. The motors help run the fans, which helps transfer and distribute the heat. If the motors break down, then the bearings will be subjected to wear and tear. This can also cause the fans to break. The entire furnace will eventually stop working.

Thermostat Problems

Your furnace may not be working properly because of a thermostat issue. Your thermostat controls the way that the heat is distributed. That is why if your furnace is not working properly, then you will need to check to see if the thermostat is working properly.

Furnace problems are extremely common. Fortunately, most problems are easily corrected. Thermostat problems, dirty filters and a lack of maintenance are some of the things that can cause a furnace to break down. Broken bearings, belts and motor can also cause the furnace to break down. Make sure that you have these problems corrected by a professional as soon as possible.
