Noisy systems are one of the most common complaints customers have about their air conditioners. And it’s no wonder! It’s almost impossible to ignore a noisy air handler when your AC starts screeching or hissing every time you turn it on.
While some people think this might just be a normal part of their system, it is not. In fact, strange sounds could signal a very serious problem with your AC. The last thing any homeowner wants is to suddenly be left with no air conditioning in the middle of the summer. That’s why it’s vital to have your air conditioner checked by a professional as soon as it starts to make strange noises.

What Do These Air Conditioning Noises Mean?
When sounds are coming from your AC, it’s all about location, location, location! Where the sound is coming from determines what the problem is. Generally, there are three main places where you will hear noises. They can come from the outdoor condenser unit, the air handler, or your ductwork.
Loud or Noisy Outdoor Condenser Unit
AC Banging Noise – The outdoor unit’s fan is hitting something. Could be an obstruction like a stick that shouldn’t be there, or the fan has come loose from the mount and is wobbling and hitting its protective cage. Do not continue to run your air conditioner, it could cause even bigger problems. Turn off your AC and get it fixed by a professional air conditioning contractor.
AC Hissing Noise – This is usually connected to a refrigerant leak.
AC Humming Noise – The motor is trying to turn on but is unable to.
AC Rattling Noise – Over time, screws in your system can become loose. When this happens, they fall and rattle around inside your AC.
AC Grinding Noise – Something is wrong with the fan motor. Generally, the fan just needs to be lubricated, but it could be a more serious problem.
AC Screeching Noise – It can also sound like a screaming noise. There is an unusual amount of internal pressure. This can be extremely dangerous. If you hear this noise, shut down your system at once and call a professional technician.
Bubbling/Gurgling Noise – A gurgling noise while your air conditioner runs can come from the condensate drain line, or could be a sign of a refrigerant leak. it probably won’t hurt anything to continue running your air conditioner, but make sure the condensate drain line has a proper trap. If you think it’s a refrigerant issue (it could be combined with warm air blowing out of the handler) have a professional check out your AC system.

AC Buzzing Noise – There is an electrical problem with your system.
