Why Is My Furnace So Loud: 4 Easy Troubleshooting Tips

Your furnace is a critical component of your home, and it should work efficiently and quietly.

Check the Motor

The motor is one of the main components of your furnace, and if it’s not working properly, it can make a variety of loud noises. The most common issue is the lack of lubrication. A well-lubricated motor will run smoothly and quietly, but it can produce a grinding or squealing sound if it’s not lubricated. If you notice this type of noise, try adding lubricant to the motor.

Inspect the Fan

The fan is another component of your furnace that can make loud noises. Rattling or clanking sounds may indicate the fan is loose or damaged. Check the fan to make sure that it’s secure and not damaged. If the fan looks okay, try lowering the fan speed. Sometimes, the fan speed can be set too high, and this can cause it to make more noise than necessary. 

Clean the Pilot Light

The pilot light is a small flame that ignites the burners when your furnace turns on. However, if it’s dirty, it can cause a delay in the ignition, resulting in a loud boom or banging sound. To clean the pilot light, turn off the gas valve and let the furnace cool down. Next, gently clean the pilot light and surrounding area with a soft-bristled brush. Call a professional for help if you’re uncomfortable doing this yourself.

Change the Air Filter

A dirty air filter can cause various issues with your furnace, including whistling noises. Over time, dust and debris can build up in the air filter, restricting the airflow to your furnace. When the airflow is restricted, it can cause the furnace to work harder than it should, leading to whistling noises. Try changing the air filter, and if that doesn’t work, you may need to bring in a furnace technician to inspect your system.
