Air Conditioner Making Noise

Aircon Problem: Noisy

Air conditioners has become a great addition to the lives of many people in so many years. Several comprehensive units have been developed in creating different models of AC. Recent versions of the cooling system have developed cutting edge technology to further improve it. This would include keeping the operation as quiet as possible. Some of which uses a sound-damping technology to lower down noises. However, one of the problems people encounter most especially to older models of the AC are the noises they create. The sound will depend on the model of the AC and the internal parts that are part of the cooling operation.

If people refuse to resolve any noises coming from their AC then this could lead to problems that could damage the system. This problem can transition from minor repair to bigger ones as the noises made are a signal for a repair. The earlier the noise is fixed the better as this would prevent further damage that is costlier. Ignoring this problem will only worsen it and will eventually cause the system to break. Most of the time, this problem will require quick and easy solutions that the end-user can do at home. But if not fixed, then technicians should be consulted for fixing.

Checking for Signs of Noisy Aircons

• Clanking and banging sound
  The AC system signals itself that something is wrong inside. Noises made could be a disruption in the process that needs quick attention. Hardware sounds like banging and clanking could mean that something is loosed or broken inside the AC. This could mean a lot of things like an unbalanced air blower, loosed connecting rod or piston. Clanking on the other hand is a sign of a loosed parts inside or the indoor and outdoor fan blades are unbalanced.
• Screaming sound
  After several years of using your air conditioning unit, one would experience sound that is not the usual. The very first thing to be done when this happens is to turn off the air conditioning system until it is carefully inspected by skilled technicians. A screaming sound resembling a high-pitched sound could mean something. This could be a refrigerant leak that needs to be patched right away as this could affect the health of the people utilizing the AC. Another reason for the unusual sound may be the pressure caused by the compressor inside the outdoor unit. Some models have a sensor in the compressor that helps the system shut down to protect the user from potential dangers.
• Clicking sound
  A clicking sound should only be heard when the AC system is turned ON of OFF during operation. Hearing a constant clicking sound during operation would be a different case and should be taken notice off. This sound would mean there is a defect in the thermostat that needs to be fixed. This could also point signs from the electrical wires that should only be handled by trained professionals.

Solutions to Noisy Aircons

• Lubricate
  The sound produced inside the system will mean that maintenance is already needed inside. A grinding sound inside would come from the motors that needs lubrication. This is easily accessible when the motors are unsealed. SAE oil can be used to lubricate the motors that is causing the grinding sound. This can be prevented by applying this oil most especially during the summer season when it is very humid and could dry up the system inside.
• Tighten the screws
  It is normal to have vibrations when your AC system is operating but sometimes when certain parts of the system is loosed, it creates certain unusual sounds. One of the sounds these vibrations may make is the loosed screws in the unit. This could be screws that are keeping the panels ON or the ones that are holding the AC in place on the wall. This would create a rattling sound made by the movements of the vibration. You can simply solve this problem by tightening the screws and that would dismiss the sound during operation.
• Clean and maintain
  There are several ways to fix and do maintenance on our own to prevent production of unusual sounds from the AC unit. Usually this rattling sound is a sign that some debris or dirt could be hindering some parts to work properly. This can be done by opening the system and locating the sound. Clean the debris around the blades and some areas that are affecting the insulation. Check if the fan blades are not bent as this could also contribute to the sound the AC makes during operation. Also, if normal cleaning does not solve the issue, then consult a chemical overhaul service for proper and more thorough cleaning.
