Why is my air conditioner so loud?

By Fahrenheit AC /

With technology improving every day, today’s air conditioners aren’t really all that noisy. If you start to hear strange sounds coming from your air conditioning unit, you probably shouldn’t ignore it! This could be the beginning of your unit trying to tell you that it’s time for an upgrade or a repair. The last thing you want is to be left with no air conditioning in the middle of summer in Florida. Generally, you will hear noise coming from the outdoor condenser unit, the ductwork, or the air handler.

 

Here are some common noises that indicate you need to look at your AC unit:

 

  • Banging or Clanking: If you are hearing this noise coming from your outdoor unit, something may be obstructing a fan or there could be something in there that doesn’t belong in there. It’s also possible that a part, such as the fan, has come loose and is wobbling around in the cage. If this is what you hear, STOP running your unit! It could cause more serious issues. These noises are usually indicators of a need to replace your system’s compressor.
  • Hissing: This noise is usually linked to refrigerant leaks, which are dangerous to you and your family’s health.
  • Humming: This isn’t necessarily a noise to be alarmed about, but it should be checked out. This could mean a loose pipe or part that is causing vibration. Humming noises sometimes lead to electrical issues. It could also mean there’s an issue with the motor. Perhaps your motor is trying to turn on but something is preventing it from doing so.
  • Screeching or Screaming: This usually means there is an unusual amount of pressure building up and you need to shut your unit off immediately and call a technician! This is very dangerous and can mean refrigerant is leaking, which is a major health hazard!
  • Grinding: This means something is wrong with the fan motor. This could be an easy fix – lubricating the part but sometimes it can mean a more serious issue.
  • Gurgling: This noise usually comes from the condensate line, but in some cases, it can mean a refrigerant leak. If you think It’s the latter of the two, call a professional to come check it out.
  • Popping: This may mean that you need new ductwork. The popping noise comes from expanding of the ductwork.

 

If you hear noise coming from the air handler, you definitely want an HVAC professional to look at it.

 

Noises coming from your air conditioning unit should not be ignored. Some of these noises may be hazardous to your health, while others might indicate a major problem is around the corner. Don’t hesitate to call your HVAC professional for your questions and concerns.
