Modern residential furnaces are designed to keep homes warm and cozy by generating heat, and since they’re complex units, they usually need regular inspection and maintenance by a licensed technician. But even with routine maintenance checks, unknown issues can occur unexpectedly due to different factors.

If you have a noisy furnace, this could be due to a number of different factors, depending on the situation. The Ice-Man, a trusted home and AC contractor, shares more insight below:
Types of Noises
- Scraping noise – This is a good indication that your furnace has a problem with its blower wheel. This isn’t an issue that you can take care of on your own, so call a professional technician to address the issue.
- Banging noise – If you hear a pop or bang whenever your furnace is running, it may simply be0 dirty. If left unaddressed, this could lead to other problems such as a cracked heat exchanger or other internal damage. Be sure to have it checked by a professional to avoid costly repairs later on.
- Whistling noise – Even a minor whistling sound coming from your furnace can indicate a leak or gap in your ductwork. This can be difficult to fix on your own, so have it checked by a professional AC repair contractor.
Other Tips to Consider
If your furnace seems relatively intact but you can’t pinpoint where the noise is coming from, don’t attempt a DIY repair. Some types of noises will only occur once you turn on your furnace, which can be due to an ignition roll-out. This is most likely a gas-ignition issue that must be addressed by an experienced professional to prevent further damage and repair costs!
