Don’t Ignore These Heater Sounds!

woman-holding-hand-to-ear-to-listenThroughout the lifespan of your heater, there are certain noises that come from it that are easy to “tune out.” For instance, if you live on a busy street, you get used to the noise of cars zipping by, right? The same concept applies to the gentle rattling of your ducts when your furnace turns on or the whoosh of air coming through the room vents. If there’s ever a heater noise you can’t tune out though, because it’s loud or very unusual, then it’s definitely not a noise you should ignore.

Usually, these types of sounds indicate that something has gone wrong within your furnace, boiler, or heat pump, and you need to pay attention, then give us a call! By alerting our team ASAP, you’ll help ensure that your heater operates as it should and is able to provide your household with efficient and effective heating throughout the years.

Not only this, but staying on top of your heater problems protects your safety too—particularly if you have a gas-powered heater. These heaters aren’t dangerous by nature, but they can become so if they are not properly cared for. Read on as we uncover some alarming noises you should never ignore, and what they likely mean for your heating system.


What you’re very likely hearing is a problem with the blower motor of your forced-air heating system.

There’s a bit of good news here, fortunately! This is a relatively easy repair for our professionals. But, you do want it taken care of right away. If a blower motor isn’t working, that means the fan won’t work. So, the heat being produced from your system has no way to actually get distributed through the vents and into your living space. Not only will this significantly decrease your comfort, but it can cause the heater itself to overheat and shut down as a safety feature.

All this means is that your blower motor needs to be lubricated! There are motor bearings that are a part of your heater, and they wear down over the years. This is natural, and they do usually need to be replaced a couple of times throughout the lifespan of your heater.


Are you listening to something that resembles metal scraping on metal? Or maybe metal that’s bouncing off of metal? Well, that probably is what you are hearing, then. This can be the sign of a big problem with your heater’s blower wheel. And if this is the case, you’ll need to turn off your heating system and contact our professionals right away to avoid further damage.

Allowing damage to occur shortens the lifespan of your heater and doesn’t do a whole lot for your wallet, either.


Are you hearing a BOOM or a BANG when your gas-powered furnace starts up? This is probably because of a dirty burner. We say that simply, but this is a more serious issue than you may realize—it can actually turn hazardous.

This sound is probably caused by a delay in ignition. What happens when the burners are dirty is that the jets fire up, but gas builds up under the dirt and grime that’s settled on your burners, and a small explosion occurs as it breaks through.

One of the bigger problems this can lead to is a cracked heat exchanger, which means that carbon monoxide gas will be able to leak into your home. This can be a fatal gas, and it’s nothing to take lightly! If you hear a boom when your furnace starts up, or if you hear a clicking when it shuts down, it’s time to give us a call.
