Five Possible Causes of a Noisy Furnace

Do you need preventative maintenance to get your noisy furnace under control?

Of course, the best remedy to scary furnace noises is regular preventative maintenance. Even if the noise doesn’t reveal danger, it is usually an indication of a problem that should be addressed sooner than later. If not repaired, the small problem can snowball into a larger, more costly repair later on.

Furnaces, especially older ones, can make a variety of different noises. Some noises can indicate you should get your furnace checked out immediately and some are just normal operational sounds.

Here’s a list of a few of the most common scary furnace noises you could get a handle on with preventative maintenance:

1. Booming: Sometimes you may hear a boom when your furnace starts. This is caused by a buildup of gas from a delayed ignition. This can be a serious problem and you should call a heating professional to check this out as soon as possible.
2. Screeching: Grinding, squealing, or screeching noises coming from your furnace are most likely a result of problems with a bearing, belt, or the motor. While this isn’t dangerous, if neglected it can lead to a need for major repairs later.
3. Clicking: Some homeowners report their furnace makes a constant clicking noise and doesn’t light. Usually, a leaking gas valve or loose wiring is to blame.
4. Rattling: If your furnace sounds like it has a screw loose when it is running, it may actually have a screw loose. Sometimes a rattling noise can be fixed by simply tightening the cover panels. Other times, a rattling can indicate a leak in your heat exchanger, which can result in carbon monoxide leaking into your home.
5. Rumbling: There is a slight but discernable difference between a rattling and rumbling furnace. Rumbles indicate that your gas burners are dirty or your pilot light may need to be adjusted.

It’s a good idea to get new, unusual furnace noises checked out by a heating professional as soon as possible. If the noise is new, something has changed and it could indicate a dangerous condition.
