Your HVAC system helps your family feel comfortable in your Swannanoa, North Carolina, home. To ensure it’s operating efficiently, it’s essential to watch for signs that it may need a repair. One way your HVAC system tells you it’s experiencing a problem is by making an unusual noise. If you hear any of these four noises coming from your HVAC system, you should consider scheduling an inspection before it’s too late:


Every moving part in your HVAC system should be properly lubricated in order for it to operate at peak efficiency. Lubricant prevents parts from wearing out too early or becoming damaged. An irregular squealing noise is a sign that the parts in your HVAC system need more lubrication.


Banging noises coming from your HVAC system signal that you have a broken or loose part. Either issue can pose an immediate danger to your system. A broken part will need to be replaced. A loose part can move around and cause damage to the other parts of your system. Therefore, it’s imperative that you contact a professional right away if you hear banging noises coming from your HVAC system.


A persistent rattling noise is often a sign of damage to the furnace blower motor. It could signify a repair need or that the motor is starting to fail. You should address this issue immediately. Otherwise, it can cause the entire system to break down, requiring you to replace it.


If you have an older gas furnace, you may have heard this sound once or twice. Since there’s no immediate problem occurring directly after, you most likely ignore it and go on about your day. Unfortunately, these booms are a signal that there’s a delay in the ignition that causes gas to accumulate, which can result in a dangerous situation. To avoid endangering your family, let a professional take a closer look.
