The 3 Main Reasons Behind a Noisy AC Unit


All homeowners want their homes to stay comfortable and peaceful, a place where they can freely unwind after a tiring day at work. That’s why when it comes to heating and cooling needs, it’s important that the systems responsible remain noiseless—a key distinction between a quiet home and a functioning one. Thanks to modern innovations, today’s AC units are more seamless than ever. The units modeled for high-efficiency utilize sound-dampening technology and two-stage compressors to make sure that noise levels are adequately low. So the next time you hear suspicious noises from your AC units, don’t ignore them, as this could be a telltale sign of a much needed inspection visit.


Banging is a loud, forceful sound. When your AC unit is emitting banging sounds, this usually signifies a loose or broken component in the unit, which could either be a connecting rod, piston pin or crankshaft. Sometimes, an unbalanced indoor blower is the culprit. Typically, a banging noise from the AC unit will require an immediate compressor repair.


Clicking is a short, sharp sound. Although electrical components often produce clicking sounds during their start-up and shutdown stages, constant clicking during operation shouldn’t be ignored. If you want to ensure premier comfort AC work, then look for signs of defective controls or a failing thermostat.


Hissing sounds occur when there’s an internal leak from a compressor valve. Since this component is responsible for the pressurization of the refrigerant gas, the valve leak needs instant repair. If left unattended for a long period of time, the issue could lead to more serious electrical problems. Do note that short hissing sounds are normal for a functional AC unit, and that they often go away after a few seconds.
