If you're hearing strange noises coming from your air conditioning system, it's important to take action right away. Whether it's a squeaking, knocking/rattling, compressor blow, explosion sound, or buzzing noise, these are all signs that something is wrong with your air conditioner and needs to be addressed. Loose parts in the indoor unit or outdoor condensing unit can cause a knocking or rattling noise. The indoor fan may have loose blades that make noise while the motor rotates the fan, and a compressor blow is a sign that there are loose parts inside the compressor.
An explosion sound of the air conditioner occurs when the system is turned on and off, and this can be caused by air entering or exiting the duct network. Refrigerant leaks due to a damaged refrigerant line or a faulty expansion valve, or poor air circulation throughout the unit caused by a dirty air filter can also cause evaporator coils to freeze. Refrigerant leaks can also cause buzzing sounds, depending on the severity of the leak and where it is located. If you notice any of these noises coming from your air conditioning system, it's important to take action right away.
Turn off the system and call a professional to repair it. If your home has an old air conditioning unit, a refrigerant leak can allow harmful freon to be released into the atmosphere; most modern air conditioners use the environmentally friendly refrigerant R-410A or Puron. To correct these noises made by the air conditioner, turn off the system and call a professional to repair it. If you think the squeaks are related to the system compressor, turn off the unit immediately and request repair services as soon as possible to protect the compressor and air conditioning system.
It is necessary to repair any leaks and recharge the system with refrigerant so that the air conditioner has the right refrigerant for efficient cooling. Don't wait until it's too late!
