Those spooky sounds coming from your heating system is your furnace’s way of signaling for help. Ignoring the distress signals could leave you with no heat and a costly furnace repair bill. Here, the experts at Northwind Heat & Air in Purcell, OK, share with five weird furnace noises you shouldn’t ignore.

5 Noises That Indicate the Need for Furnace Repairs

1. Shaking & Rattling

In general, a rattling sound means something has come loose or is quickly working its way loose. This noise usually points to a problem with the motor mounts, which are causing the unit to shake. It is also sometimes caused by a misaligned blower.

2. Clicking

The normal clicking sounds of your furnace starting up and shutting off are no cause for concern. It is repeated clicking that indicates a potential problem. A broken relay is usually the culprit of this sound.

3. Screeching

A worn belt causes loud screeching. This is a problem you definitely should not ignore: Without it, the blower on the furnace won’t operate. It is much easier and less expensive to have a furnace repair professional fix this part before it breaks. 

4. Booms

If you hear a loud boom when your furnace starts, chances are the burner assembly is dirty.  A dirty burner is the result of carbon particles that build up and clog the furnace burner. When the jets ignite, they have to produce a significant amount of gas to get the burner to fire. Over time, this buildup of carbon and jet misfires can become dangerous.

5. Chirping

If you just fired up your furnace for the first time this season, you may have heard a chirping noise. This is typical for the first few minutes as the system starts up. If, however, it doesn’t go away, it likely means your furnace needs new fan belts.
