Now that winter is fast approaching, it’s time to think about possible furnace problems before you’re left in the cold.

There are many signs of furnace problems that can indicate that the furnace is not working as well as it could, such as increased energy bills.

However, a higher energy bill isn’t the only sign your furnace needs repair. Once you learn to recognize the warning signs, you’ll be able to troubleshoot any issues before they turn into a big repair.

Keep reading to learn more about how to recognize and repair furnace problems before they get too bad.

Furnace Problems Caused by Dirty Filters

Not cleaning or replacing the filters for your furnace can lead to heating issues, and if left unchanged, cause major issues when cold weather comes.

Your furnace has to work harder, and a strain is put on the motor, which leads to higher energy bills, less heat being produced, and can cause damage to the limit switch. 

It’s smart to clean dirt and dust and replace the furnace filter at least twice a year. This will help keep your furnace running at its best. If your furnace is frequently cycling by turning off and on constantly, then it may be caused by a clogged filter. Cycling can also be a problem with the thermostat or bad airflow.

Changing your filter should always be the first maintenance attempt, as it can lead to many other issues. It’s important to have regular maintenance for your furnace as well.

Damaged Blower Belt

If you are hearing a high pitched squeal, the problem may be that you have a damaged or frayed blower belt. Replacing a damaged blower belt before it completely breaks can be the difference between a $20 expense and a few hundred dollars to replace the entire furnace blower. 

If the blower continues to run without turning off, then the issue may be with the limit switch rather than the belt.  This will cause problems with trying to regulate the temperature and increase your heating bills unnecessarily. 

Worn Out Ball Bearings

If you hear loud scraping sounds when you turn the furnace on, then it’s important to turn the furnace off immediately and call in an expert.

Continuing to run the furnace when it has worn out ball bearings can cause irreparable damage and put you at risk of having a fire, because it means metal is scraping against metal.

Yellow or Flickering Pilot Light

A yellow or flickering pilot light on your furnace could lead to dangerous levels of carbon monoxide building up in your home. This isn’t just a concern, it can be deadly. It’s critical that every home has a carbon monoxide detector to alert you when there is an issue.

If your furnace pilot light is flickering or has turned yellow, then it is best to err on the side of caution and get everything checked out to ensure there isn’t a build up of carbon dioxide threatening your family. 

Malfunctioning Limit Switch or Thermostat

A malfunctioning limit switch or thermostat may have your furnace running continuously. This can be an easy fix if it is just the thermostat, but may need professional repairs to replace a malfunctioning limit switch.

It will be hard to regulate the temperature to keep your family comfortable if you don’t get these types of issues fixed early on. 

Fix Furnace Problems Early

The earlier you identify and rectify any furnace problems, the more comfortable and safer your family will be. If you don’t take the time to do regular maintenance, then you’ll be paying for it in the long run with expensive bills for repairs of bigger problems, or may even have to replace the furnace all together.
