Summer is already here, and the temperatures are beginning to soar. This kind of weather makes your air conditioning unit your best friend. However, just because your AC is running doesn't mean that it is running efficiently or safely. A poorly maintained AC unit can lead to higher energy bills, decreased cooling efficiency, and even dangerous health risks. It is, therefore, essential to know the signs that indicate that your AC needs servicing. Here are some of the sounds that you should watch out for to keep your AC unit running efficiently.

Squealing noises

If you hear high-pitched squealing when you turn on your air conditioning, it could indicate a problem with your unit's belt. A worn-out belt produces a squealing sound when it slips out of position. It would be best to turn off the unit immediately and call an HVAC professional to inspect it. Continuing to run the AC could lead to extensive damage to the belt, leading to a breakdown of the unit.

Rattling and shaking

If your AC unit is shaking or rattling, it might be a sign of loose or displaced parts. The shaking can cause the unit to produce an increased amount of noise. It is crucial that you do not ignore these sounds as they could lead to further damage to the AC. Contacting an HVAC professional to inspect the unit is the best way to identify and fix the problem.


A low humming noise coming from the AC could indicate a problem with the electrical components. Components such as the capacitor and the fan motor can produce this kind of sound. Ignoring this noise can lead to overheating, which can cause irreparable damage to the AC unit.

Hissing and bubbling

Hissing or bubbling noises means that it is likely that your AC unit has a refrigerant leak. When refrigerant leaks, the AC unit becomes less efficient in cooling, and it could eventually break down completely. A leaking refrigerant could also lead to health risks, such as headaches, dizziness, and nausea. It is imperative that you call an HVAC professional as soon as possible to fix the leak and refill the refrigerant.


Clicking sounds could indicate problems with the AC's electrical components. Ignoring clicking noises could lead to an electrical fire or more extensive damage to the unit. A professional HVAC technician can quickly identify and fix the problem.

AC servicing is essential to keep it running efficiently and safely. As a homeowner, it is crucial that you know how to identify the sounds that indicate a problem with your AC. Paying attention to these sounds and contacting an HVAC professional to inspect your unit could save you from many issues. Don't hesitate to contact HVAC professionals to fix the problem.
