If your furnace is getting older, it may start having problems soon. So you know what to look for, below are three issues you may have to deal with. You can then hire a heating system repair company to repair your furnace to get it running again.
Your furnace may get to the point where it constantly cycles, meaning it turns off and on much faster than normal. This can be caused by a bad filter. Check the filter, and if it is dirty, replace it. You may have a reusable filter, and if so, clean the filter and put it back in. Constant cycling can also be caused by a bad thermostat, or the airflow may be blocked.
This problem can be hard to find, so you should hire a heating system repair service. Your energy bills will go up if this is not repaired. This is because constant cycling causes the furnace to run longer than it normally does. This can also cause other parts of the furnace to wear out quicker.
Bad Blower Belt
If your furnace starts making a squeaking sound, this can be caused by a bad blower belt. The blower belt is between the motor inside the furnace and the blower. The belt can wear down over time and then eventually break. Fortunately, replacing a worn-out or broken blower belt is not difficult, and you can likely do this on your own.
To open the furnace, there should be an access panel on the back of it. This panel will have screws that keep it closed. When you open the panel, you should see the belt. Refer to the owner's manual for your furnace to know how to replace the belt.
Damaged Heat Exchanger
The heat exchanger is the part that separates the air that you and your family breathe and the combustion process from the furnace. The heat exchanger is located at the beginning of the burner assembly and ends at the vent that is connected to your furnace.
If your heat exchanger is damaged in any way, such as cracked, this will cause the combustion process to leak and make a smell around the furnace. This can be dangerous if your family breathes this in, so contact a heating repair service immediately. Turn the furnace off until they arrive to fix the problem.
