Understanding and Addressing Loud Banging Noises from Your Air Conditioning Unit
Summer months can be unbearable without an air conditioning unit, so it's imperative to ensure that it is running smoothly without any issues. However, if you start hearing loud banging noises, it can be an indication that something is wrong with your unit. The banging sound is not only irritating but can also signify an underlying problem that should be addressed as soon as possible. Here are some of the reasons why your air conditioning is making loud banging noises and what needs to be repaired.
Loose Parts: A loose part within the air conditioning unit can lead to loud banging noises. This typically happens when your air conditioning is running, and something within the unit comes loose and bounces around. The most common parts that are likely to become loose and make noise are the blower wheel or fan blades.
Dirty Coils: Over time, the coil in your air conditioning unit may become dirty due to the accumulation of dirt, debris, and grime. Dirty coils can cause a range of issues, including loud banging noises. In this case, the noise is caused by the refrigerant, which flows through the coils, and when it encounters an obstruction, it causes a banging sound. In these cases, cleaning your coils can help eliminate the noise.
Blocked Air Ducts: When the air ducts within your air conditioning unit become blocked, the air will have difficulty passing through, creating a loud banging noise. Blocked air ducts prevent the flow of air, causing the air conditioning to work harder than usual and leading to the noise. Air ducts can become blocked by a variety of things, including dirt, dust, and debris.
Refrigerant Leaks: Refrigerant leaks can also lead to loud banging noises. This noise is caused by the sudden expansion of fluids or the change in pressure within the air conditioning unit. Refrigerant leaks not only result in loud banging noises but they can also cause reduced performance and higher energy bills.
Faulty Compressor: If the banging noise is coming from the outdoor unit of your air conditioning unit, it could indicate a faulty compressor. The compressor has the task of circulating refrigerant throughout the unit, and if it malfunctions, it can result in noisy disturbances. To resolve the issue, it is necessary to have a professional replace a faulty compressor.
It is essential to take action when you hear loud banging noises from your air conditioning unit. When left untreated, these issues can cause more extensive damage to your unit, leading to a more expensive repair bill. Any repairs to your air conditioning unit should be performed by a professional licensed technician.
