What Does My Furnace Noise Mean?
To be perfectly frank, the following troubleshooting tips are based on what each sound most commonly means, but it’s not necessarily the meaning. For example, we say a loud hum means the fan needs replacement but a banging sound could also mean that, so take all of this with a grain of salt.
- If your furnace blower creates awhooshsound in the vents, you probably just need toadjust the fan speed.
- If it’s more of awhistling sound, then it means there is a gap between the blower and the vents. The source is probably an expiredfilter that needs replacement.
- If you hearloud humming, then you can probably take care of it bycleaning the blower fan. Extreme cases may mean you have worn bearings that need replacement. The friction created results in more current drawn. Replacing the fan altogether might be necessary if you find it is damaged.
