You Can’t Ignore These 4 Ductless Sounds in Charleston, SC

Ductless mini-split systems offer a great way to boost comfort and efficiency in your Charleston, SC home this summer. These systems provide relatively quiet cooling so you can avoid hot spots and insufficient airflow in the house. If you have a noisy ductless system, read below to find out what the sounds may mean.

1. Rattling or Clanking

A loud rattling or clanking noise coming from your cooling system could indicate a loose or broken part. The part may make a loud clanking or banging sound as it moves around inside the system and bumps against other components. Immediate repairs are essential to minimize further damage.

2. Humming or Buzzing

A humming or buzzing sound in the ductless system could indicate an electrical issue. This could result from a loose connection or faulty computer that causes the system to draw too much power. These issues can result in higher energy consumption and premature failures from excessive wear.

3. Hissing or High-Pitched Whistling

Hissing sounds or a high-pitched whistling noise from the mini-split often indicates a refrigerant leak. As the refrigerant leaks out of a line, it makes this sound. Refrigerant leaks are hazardous to people and the environment, and these noises can cause your system to fail in making cold air.

4. Grinding

If you hear loud grinding noises that sound like metal scraping against metal, you probably have a loose component inside the mini-split system. It’s imperative to call for repairs right away to prevent further damage to the faulty components and any others it may be rubbing against.
