When it comes to our AC, we want them to be seen but not heard. However, if the loud condenser unit destroys the tranquility of your house, then you should not ignore it. In fact, the humming sound is very likely to indicate that the system has some very serious problems. If you want to know what noisy sounds mean, it may be time to check the air conditioner.
Every communication system is different. This means that there is no real way to know exactly what is wrong with the system until the professional has checked the device. However, common communication sounds are usually a sign of certain problems. If you hear any such noise from the condenser unit, you should call an HVAC professional immediately.
Hiss: A hiss usually indicates a refrigerant leak. Refrigerant is a very harmful chemical substance and can only be handled by professionals certified by the Environmental Protection Agency.
Popping sound: When you turn off the AC power and hear a loud popping sound, it may be an installation error. Even if the motor is turned off, this may cause the motor to move and generate noise.
Buzzing sound: If the condenser unit makes a humming sound, it is likely that the system has an electrical fault. There may be a problem with the circuit breaker or other electrical components of the AC.
Buzzing: This noise is usually produced when the system tries to start but fails to start.
Sharp sound: If you hear any sharp sound from the outdoor condenser, turn off the system immediately. This is usually caused by extremely dangerous internal pressure. It is very important that professional AC technicians provide services to your system immediately.
