Furnaces – like all machines – aren’t entirely quiet. A properly functioning furnace makes a low humming sound that fades into the background. If you hear any other noise but that one coming from yours, then it almost certainly needs to be looked at by a furnace repair expert. But the noises it can make vary, and each possible noise indicates a different potential problem. Read on to learn about some of them.

Signs of Furnace Issues 

1. Banging

Banging can indicate the presence of broken or loose parts in your furnace. Don’t ignore this noise. If caught early, a furnace repair expert can open your furnace, retrieve the broken or loose part in question, and replace or repair it. Ignoring it can lead to much higher repair costs. After all, the part is freely banging around your furnace, so there’s a chance that it can collide with other parts of it, breaking them too. 

2. Squealing

Erratic and irregular hitch-pitched cries can indicate that there are components in your furnace that need lubricating. Furnaces require maintenance and not doing it regularly could lead to this problem. More regular squealing, on the other hand, could indicate worn-out motor bearings that need replacement. Again, ignoring this sign has serious potential consequences – the motor, for example, may eventually overheat and fail, and replacing the motor will cost you a lot more money than replacing just the bearings.

3. Clicking

A flurry of short-lasting, rapid clicks when you turn your furnace on and off is completely normal. In fact, it means that everything’s in working order. But if your furnace continues to click for over a minute, it may indicate an electrical issue that should be checked out by a professional.
