7 Furnace Noises You Should Never Ignore
Aside from a very low-key hum, your furnace remains fairly quiet for the most part. So when a strange noise pops up, you know that something must be wrong. But how big of a deal are furnace noises?

7 Noises That Indicate Furnace Problems
No unusual furnace noise is ever really a good thing, and in fact, nearly any sound is, in fact, a very good reason to call in for repair. But of all of the sounds you can encounter, these seven are the biggest and baddest:
- Squealing. Irregular squeals are very often components that should be routinely lubricated that haven’t been maintained recently enough. This can be a big problem because many of them are prone to incurring damage without lubrication, leading to some pretty big furnace damage.
- Screeches. Nine times out of ten this is going to be a worn out or cracked belt in your furnace. Of all of the sound on this list, screeches are both the most annoying and the least threatening. But once that belt breaks, you won’t be getting any heat until it’s replaced.
- Bangs. Banging means loose or broken parts. This might be the biggest threat on the list, as that loose part can literally bang around and break other components, leading to massive repair costs if not a complete replacement.
- Persistent rattling. A failing furnace blower motor is the most likely cause here. This is your best warning sign before the assembly goes out entirely, which can lead to cold nights in the near future.
- Fluttering. Fluttering isn’t exactly the perfect descriptive here, but it’s kind of a hard sound to replicate in type. Thwap? Whap? In any case, this is often debris caught in your fan. Try sticking a bit of cardboard into a fan and you’ll get the idea. (Don’t actually do that. Just envision it.)
- Long-lasting clicks. Does your furnace perform a rapid series of tinking clicks when it cuts on and off? If so, that’s normal. But it’s not normal for that sound to last longer than a minute. And if it does, you probably have an electrical issue on your hands.
- A notable boom. Any boom is notable, and if you’ve been around a really old gas furnace system, you’ve probably heard this once or twice. But what that sound is is often a delay in ignition for gas furnaces, which can actually be kind of (very) dangerous. Call in for repair!
Essentially any furnace noise at all usually means a problem of some sort, and almost all of them mean serious business. If you hear a worrisome sound, go ahead and give our team a call for professional furnace repair!
