A/C units can be noisy. Here are the noises to be aware of that indicate something may be wrong.
Loud Humming: A common cause of loud humming is loose parts. Often, this kind of sound isn't very serious, but you don't want to ignore it. .
Buzzing Noises: Hear buzzing from your outdoor unit? The could be debris in your unit, the air filter needs a change, or your blower might be out of balance. .
Clicking: If you hear clicking at the startup or shutdown of your AC, it's normal. If the clicking sound is constant or getting faster, you may have a problem... possibly an obstruction.
Squealing: Not only annoying, but could be the symptom of a misaligned or worn down fan belt. .
Hissing or Bubbling: This could be the sign of an internal leak. Leaks will only get worse over time, so be sure to get this looked at sooner than later.
