Why Is My Air Conditioner So Loud?

It’s summer time, and Central Florida is already heating up, and the more the temperature rises, the more we rely on our AC’s. So if anything goes wrong with our trusted systems, we need to know what’s wrong and how to fix it, ASAP!

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 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 that you will hear noises. They can come from the outdoor condenser unit, the air handler or your ductwork.

Loud or Noisy Outdoor Condenser Unit

Banging Noise – A faulty mount may cause loud banging sounds when your system shuts off.
Hissing Noise – This is usually connected with a refrigerant leak.
Humming Noise – The motor is trying to turn on, but is unable to.
Rattling Noise – Over time, screws in your system can become loose. When this happens, they fall and rattle around inside your 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.
Screeching 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.

Loud or Noisy Air Handler

Buzzing Noise – There is an electrical problem with your system.
Hissing Noise – There may be a leak in the refrigerant line.
Clicking Noise – There is an obstruction in the fan blade. Clicking noises can also be caused by problems with the thermostat.

Ductwork Noises

Popping Noise – This happens when the ductwork expands and moves out of shape. It is a sign that you may need new ductwork.
Rattling Noise – This is usually connected with a bad blower fan.
Scratching Noise – It’s not uncommon for animals to get trapped in ductwork. Any scratching, scurrying or rattling movements may mean you can some unwanted visitors.
