Aside from being more efficient, air conditioners today are meticulously engineered to produce little to no noise at all. So, when you hear something unfamiliar coming from your unit, make sure to look into it.

Usually, a hissing or whistling noise coming from an AC isn’t that serious. But if it’s persistent and lasts more than a few seconds, then it could be a refrigerant leak. 

This can worsen over time if left unchecked and not fixed immediately. The hissing will intensify, and your unit’s overall efficiency will certainly decline. If you suspect that you’re dealing with this kind of problem, turn off your unit immediately and wait for it to be repaired by a professional. 

This kind of noise may signal loose fan blades or a faulty fan motor in your outdoor condenser unit. These can be easily fixed, but sometimes, buzzing noises can also mean that your unit has electrical problems. This is a usual issue with older AC units.

Although this doesn’t typically affect your unit’s efficiency, it can still be a fire hazard. So, if you notice a buzzing sound coming from your unit, turn it off and unplug it from the socket to prevent electricity from going through.

Unusual grinding noises coming from appliances and other mechanical products are surely a bad sign. If you hear that from your car engine, you’ll bring it immediately to the auto repair shop to have it checked so you can avoid an accident. It’s best to do the same thing when there are metallic grinding sounds in your AC.

One of the most common causes of this is a loose blower fan rubbing against other components inside. This is a minor problem that can be resolved by a technician. 

These are just a few common telltale noises that can be signs of mechanical or electrical issues with your AC. If you suspect that you’re currently dealing with any of these, it’s best to schedule a house visit from a professional technician so they can fix your air conditioner.
