This is usually the sign of a dirty burner. When the burner of your furnace is dirty, it can have a tough time igniting. Meanwhile, it is slowly filling up with gas to feed the flame. When the burner does finally ignite, it can cause an explosion slightly larger than intended and create a popping sound. Regular maintenance is a must to keep the burner clean.
The banging might sound a little bit like thunder. This is often caused when the air ducts begin to expand and contract due to the warm air. Professional HVAC technicians can remedy this problem by sealing off, or insulating, the ducts. Your ducts might also be undersized, and in that case, they may need to be replaced.
When is this ever a good sound in regard to a piece of mechanical equipment? The sound of metal scraping indicates a serious problem in your furnace, and it’s important to seek professional service right away. Often, this is the sound of a broken burner wheel, which allows your furnace to properly heat your home.
More often than not, consistent rattling and rumbling is a sign that something is not completely secured. In the best-case scenario, you will simply need to tighten a few bolts. However, it can sometimes indicate a problem with the furnace’s motor.
