Why Is My Furnace Making This Noise?

The last things you want to hear are strange noises coming from your furnace. Some of them may suggest a small issue, while others may indicate a serious safety risk. 

No matter what strange sounds you hear coming from your furnace, you should have a professional inspect it to determine the issue. However, you must know what odd furnace noises could mean and which sounds need to be addressed immediately. 

Common Furnace Noises and What They Mean

Anytime you hear an unusual sound coming from your furnace, you should schedule an inspection with a trusted HVAC repair company to ensure your safety. However, some sounds are more concerning than others. Here is a list of common furnace sounds and what they could mean:

Shrieking

If you hear a shrieking noise coming from your furnace, it could mean there’s an issue with the motor, or your furnace has a damaged belt. This noise doesn’t indicate a serious safety risk, but it can tell you that your furnace may soon stop working. Reach out to an HVAC maintenance company for repairs before the issue gets worse. 

Rattling or Rumbling

Rattling or rumbling sounds can show that there’s something loose inside your furnace causing vibration. Don’t ignore this noise because it may just be a loose part that a professional can easily tighten. However, if left unaddressed, the loose part can cause other damage to your heater and make for more costly furnace repairs. 

Booming or Banging

A booming sound is one of the most concerning noises you may hear from your furnace. When there’s a problem with the ignition, a tiny gas explosion may occur. 

If there’s an ignition delay, gas can collect inside your furnace’s combustion chamber. This condition can lead to a dangerous gas leak inside your home if left unaddressed, so it’s essential you call a professional to immediately inspect your furnace.
