- Grinding noises. This usually indicates metal parts, such as the fan, grinding against other parts: increasing friction and enhancing the chances of a motor overload.
- Booming noises; especially when the furnace starts up. This might mean a problem with the burners releasing too much gas or a similar issue.
- Rattling noises. Rattling noises could mean a loose bolt or another object in the heater itself, or a fan motor or similar component that is loose in its housings and vibrating as it works.
- Groaning noises. Groaning noises sometimes arise on a cold day when you first start your furnace up. The cold metal of the ducts can sometimes stretch a bit when the warm air hits it. On the other hand, it could indicate a component under considerable stress, and in any case, probably needs the attention of Green Apple Mechanical NJ professional.
- Clunking noise. A clunking sound could indicate a fan blade that is out of alignment, or a cracked fan belt which is thumping in its rotation.
