What the Noises in Your Air Conditioner Could Mean


Air conditioners, especially the new ones, make little to zero noise when running. So, if you start hearing unusual sounds in the air conditioning unit in your office, it could be a sign of a problem. You might hear various noises, and each is a sign of a simple or serious concern. It helps to familiarise yourself with these noises to determine the best action to take.

Some noises could be due to dirt you could clean on your own or a malfunctioning part that requires professional service. If you are not confident or unsure about cleaning, it’s best to leave everything to the professionals. A trustworthy air conditioning Brighton company can do the job if your business operates in Sussex. Dealing with a service provider that is located around your area is more practical since you can get fast assistance when you need it. Below are the common noises you may hear from your commercial air conditioner.

Bubbling noise

Excess moisture is the common cause of bubbling noises from the AC, which is often due to damage or blockage on the drainage pipe. Replacing the broken pipe requires special skills and tools, so it’s best to let the experts do the work. Making it a DIY project could worsen the issue, leaving you with more expenses and further inconvenience.

Hissing sound

There are various possible causes as to why you may hear hissing noises from your air conditioner. One of them is that the air filter may not be appropriate for your unit. It could also be due to a broken expansion valve. Another common reason for this noise is a leak in the air duct. So, further investigation is needed to determine the actual cause. Since it requires digging deeper into the system, it’s also something that only a professional should do.

Clicking sound

It’s natural for air conditioners to make a clicking sound at the beginning of a cycle and its end. However, if you continuously hear this sound while the AC runs, then something could be wrong. The usual cause of this is a faulty thermostat. Removing the broken thermostat and installing a new one also requires the help of an expert to ensure that it’s done properly.  

Rattling sound

Rattling sounds may or may not be serious. Leaves, dirt, and other elements that made it in your condenser outside could cause it, so cleaning it could do the trick. If this is not the case, it’s more likely due to a broken electrical contractor. Get professional help immediately before it affects the AC’s compressor, which could lead to a bigger problem.

Buzzing noise

This noise could be a problem with the fan. Either the fan motor of the outdoor unit is faulty, or its blade may be unbalanced or broken. Other possible causes for this sound are blockage around copper lines, loose parts, and unclean condense coils.

Act immediately when you hear unusual noises coming from your air conditioner. Get professional service to prevent the issue from worsening.
