Banging, Buzzing and Troublesome Ductless AC Noises

Ductless AC Noises

Your ductless air conditioner should cool your Newnan, GA, home with minimal noise. When you hear loud banging, buzzing or other strange sounds, it’s time to investigate. Take a look at a few of the common noises your ductless AC system might make that indicate the need for repairs.

Banging and Clanging

Loud banging and clanging noises coming from your ductless AC system often spell trouble. These noises may be due to loose or broken parts inside the system. As these parts move around and bump against other parts of the ductless AC system, they make the loud banging noises.

Buzzing

Light buzzing or humming can be normal during your mini-split’s cooling cycle. However, if the buzzing becomes loud, it could indicate an electrical malfunction. When you hear this loud buzzing, power off the system and call us for repairs right away to avoid electrical hazards and further damage to the system.

Rattling or Vibrating

Does your ductless AC system sound like something is rattling around or vibrating inside? Debris can get inside the outdoor unit and may vibrate or rattle when the system cycles. Our service technicians clean out the unit during annual maintenance and remove the object causing the disturbance.

Hissing or Bubbling

When air gets into the refrigerant lines through a hole, you might hear a bubbling sound. Hissing often indicates a refrigerant leak and damage to the lines. Refrigerant leaks require immediate attention as the substance can be harmful, and your system cannot make cold air without it.

Understanding which sounds are common and which trigger the need for repairs is crucial in keeping your ductless AC system operational. If you hear strange noises and need top-tier repair services for your ductless mini-split, call Merrell & Associates for service in Newnan, GA, today.
