Noisy Air Conditioner CompressorThough some noises come with the territory of owning an AC unit, there are many sounds your air conditioner could be making that are too out of the ordinary to be ignored. While we’re just now welcoming in spring, for those experiencing a noisy air conditioner compressor, these sounds could be symptoms of a pre-existing issue in your unit that needs to be resolved right away. With the hot Phoenix summer months approaching even more quickly than usual, you don’t want to be caught without a properly functioning air conditioner.

Should you notice any of the following compressor sounds, it’s best to contact a professional air conditioning repair company in Phoenix immediately to make sure you’re set for the hot days ahead.

Hissing  

A hissing noise emanating from your air conditioner compressor could be a sign that you have a refrigerant or coolant leak somewhere within your unit. This may be accompanied by a possible bubbling noise. While a sealant may be used for a quick fix to a coolant leak, it won’t be cost effective or helpful in the long run—a Phoenix area heating and cooling company will be much better equipped to fix such a leak. 

Screaming 

If you hear a screaming noise coming from your AC unit, shut it off immediately and contact your heating and cooling specialist. The excessive internal pressure that causes these types of noises is too dangerous to keep that unit running any longer, and you definitely need the help of a professional. 

Buzzing 

Loose wiring is quite possibly the cause for your AC unit to buzz. Your air conditioning specialist will be able to effectively locate and fix this issue during the necessary AC compressor repairs. 

Clunking or Rattling

These types of noises are generally caused by loose hardware, which might require either the simplest or most complicated of fixes. While you very well may be able to quell these sounds by tightening a loose bolt, the cause may be something much more complicated, like bent internal refrigerant tubing. Either way, it’s best to have a trained professional check out the issue to make sure everything in your unit is in proper condition. 

Squealing 

A squealing noise is normal upon first installing a new unit, but if it doesn’t go away after a few seconds, it’s time to call your technician. 

Loud Clicking or Ticking

There are a few different explanations as to why you may be hearing AC unit compressor noises, such as a clicking or ticking sound. One is that debris may have fallen unexpectedly in your unit and is obtruding its normal functions. Another is that your fan screen is bent and the fan blades keep knocking against it. Your heating and cooling specialist should be able to locate the source of the sound very quickly and fix the issue.

Though the noise itself may be the only inconvenience you’re experiencing with your air conditioner, it could be indicative of a bigger problem that’s yet to come. Don’t put off getting your noisy air conditioner compressor fixed today!
