If you’re like most homeowners, you probably don’t think about your furnace until it stops working. And by then, it’s usually too late. Unfortunately, furnaces are one of those appliances that we tend to take for granted – until they break down and we have to call a repairman. This article will discuss three common furnace noises that you should not ignore. By being aware of these noises, you can catch problems before they turn into expensive repairs!
1. Banging or Popping Noises
One of the most common furnace noises is a banging or popping sound. This is usually caused by something called “flame roll-out.” Flame roll-out occurs when the flame in the burner chamber gets too large and starts to roll out of the chamber. This can damage the furnace and is a serious safety hazard. If you hear this noise, turn off the furnace and call in a professional company for HVAC service in Atlanta immediately. They will have the proper tools and training to fix the problem safely.
2. Screeching or Squealing Noises
If your furnace is making a screeching or squealing noise, it’s likely due to a slipping belt. When the belt that connects the motor to the blower starts to slip, it will make a high-pitched squealing noise. If left unchecked, this can eventually cause the motor to overheat and fail. You may be able to temporarily stop the noise by lubricating the belt. However, you’ll need to replace the belt as soon as possible to avoid further damage to your furnace.
3. Rumbling or Humming Noises
The inducer motor is responsible for drawing air into the combustion chamber. If this motor fails, it can cause a rumbling or humming sound. This failure is typically caused by a faulty switch or a clogged filter. This can make your furnace work harder, which can shorten its lifespan. It will also help if you know how often you should change your furnace filter, as a clogged filter also reduces your furnace’s efficiency. The best way to fix this problem is to call a furnace repair technician.
To Sum It Up
With that being said, those are three furnace noises that you shouldn’t ignore. If you hear any of them, make sure to call a professional company for HVAC repair right away. By doing so, you can avoid expensive repairs and keep your furnace running smoothly for years to come!
