That “Ghost” in Your House Might Just Be Your Furnace!

We’ve all seen the scary movies — sitting home alone and hearing an ominous coming from somewhere in your house is just about the worst thing in the world! But, what if we told you that instead of calling the Ghostbusters, you gave your old pals over at AirSouth Cooling and Heating a call?

See, those ghostly noises you’re hearing might just be coming from your furnace! In fact, there are plenty of sounds that your furnace might make that you don’t quite want it to make, and below, we have outlined some of them for you. All you have to do is keep reading to find out more (and, when you know you need repairs, remember to call our team when you need furnace repairs in Brandon.)

What’s With all the Commotion?

Like we mentioned above, there are a number of sounds you might hear from your furnace that you don’t quite want to hear:


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.


In many cases, the banging or booming sounds you may hear coming from your furnace can indicate a dirty burner. The noise is caused by a delay in ignition due to dirt build-up on the burner, which of course, is not something you should be cleaning yourself. Instead, hire a professional who can handle the dirty work.


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 of course, can be quite dangerous. See, a cracked heat exchanger could allow carbon monoxide and other harmful gasses into your home. Your best bet in this case is always to contact a pro.

Yes, You Need to 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.

Running your furnace with an existing problem will only make matters worse, making for higher repair costs and higher heating bills. Plus, some issues can become quite dangerous if left unattended. Therefore, it is always best to call in a professional at the first sign of trouble — trust us, you don’t want to wait!
