Keep Your Ears Open For…

There are a number of strange sounds you definitely don’t want to hear from your furnace:


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

Clanking or Grinding

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 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. The gas builds up inside your system, and when it finally ignites, a small explosion occurs inside your furnace. Do not worry though — an HVAC professional can repair this issue for you!


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, which could lead to a carbon monoxide leak. Therefore, it is important that you call for repairs right away if you hear rattling sounds from your furnace.

Hire a Professional!

If you’ve heard any above-mentioned strange sounds coming from your furnace, it is best to contact a professional as soon as possible. Your local technician will thoroughly inspect your system to make an accurate diagnosis. See, running your furnace with an existing problem will only make matters worse, making for higher repair costs and higher heating bills.

And of course, there will be plenty of amateurs willing to service your system for a questionably low price, but sometimes an attempt to save money could end up costing you much, much more in the long run.
