Should Your Furnace Be Making Weird Noises?

Alright, we are going to go ahead and answer that one for you with a big, old “No!” See, your furnace should not be making any weird noises, and if it is, it is definitely a cause for concern. Why? Because weird noises indicate that something is wrong with your system!

There are a number of strange noises you don’t want to hear from your furnace, and below, we have outlined a number of them for you. All you have to do is keep reading to find out more (and, of course, remember to call our team when you need furnace repair in New Braunfels, TX.)

Keep Your Ears Open!

Like we mentioned above, there are a number of sounds you don’t want to hear from your furnace. These include:


A loud screeching sound is a sign that the blower motor in your furnace is not working properly. The blower motor is the mechanism that pushes the heated air throughout your ductwork system.

It could be that your blower motor needs lubrication, however, a screeching sound could also suggest that the fan has stopped altogether. Your local HVAC technician can assess your system to make an accurate diagnosis.


If the sound you’re hearing sounds like metal-on-metal, it could be that there is a problem with the furnace’s blower wheel. If this is the case, it is important that you turn off your furnace and contact a professional as soon as possible to prevent further damage to the wheel.

Bangs and/or Booms

In many cases, the bang or boom sounds you may hear coming from your furnace indicates a dirty burner. The noise is caused by a delay in ignition due to dirt build-up on the burner. If a dirty burner is the culprit, please do not attempt to clean it off yourself! This is truly a job for trained professionals.


Rattling can indicate a number of issues, from mild to major. Sometimes, it can suggest that there is a loose panel or screw somewhere on or within the furnace. In other cases, it could mean that there is a crack in the heat exchanger. A cracked heat exchanger is quite dangerous, as it could allow carbon monoxide or other harmful gasses into your home.
