Posted on

Your air conditioning unit is your companion on hot summer days. It is essential to keep it in good condition so that it can cool your home properly when you need it most. Sometimes, you may hear strange noises coming from your AC. It may be tempting to ignore them, hoping they will go away, but that can be a costly mistake. Some sounds are an indication that your AC needs repair immediately. This blog will discuss the different sounds that may signal an issue with your AC.

Grinding Noise

A grinding sound may indicate a problem with the fan motor bearings, and you should shut off your AC unit immediately to avoid further damage. A professional technician will need to diagnose and replace the defective part.

Squealing Noise

A high-pitched squeal noise means a belt is misaligned or worn out. The belt is used to connect the AC's motor to the blower fan. While a worn-out belt might have simple fixes, if the issue is a misaligned belt, you will require the services of a professional technician.

Gurgling or Bubbling Noise 

This sound typically means that there is a refrigerant leak or air in the system. A refrigerant leak is a harmful and costly problem that needs the attention of an experienced technician. Fixing refrigerant issues should never be a DIY task. Always seek the help of a licensed professional.

Clicking Noise

A clicking sound is usually heard when the AC is turning on or off. However, constant clicking may indicate a damaged control panel, defective thermostat, or failed electrical relay. An HVAC technician will need to diagnose the cause of the clicking sound and repair or replace the faulty component.

Rattling Noise

A rattling sound may come from loose parts, including screws, fan blades, or debris in the HVAC system. It could also signal a more significant problem with the unit, such as a damaged motor or compressor. Whatever the cause, a professional technician will be able to diagnose and fix the issue.

It's important to listen for any strange sounds coming from your AC because it can indicate issues that need repair. Ignoring these sounds may lead to costlier and more severe problems. This applies to both residential and commercial AC units. If you hear any of the sounds mentioned above, it's best to turn off your AC unit and call a licensed professional right away.
