Why Does My Chino, CA, Ductless System Make So Much Noise?

One of the signs that your ductless system has an underlying problem is an unusual amount of noise. Although some noises are more concerning than others, it’s always safest to have a comfort advisor inspect your system if you’re uncertain. Read on to discover the meaning of some ductless system noises in Chino, CA.

Hissing Noises

Your mini-split system uses refrigerant to move heat between your indoor and outdoor units. If there are punctures in the refrigerant lines, the fluid will escape through them.

Since the fluid is at a high pressure, you’ll hear hissing sounds. You may also hear gurgling noises when air enters the refrigerant lines through the holes.

Don’t attempt to fix the issue on your own, as the fluid can be harmful to human beings and the environment. A comfort advisor has the qualifications to handle refrigerant safely.

Rattling Noises

Your ductless system’s components may become loose with time. Loose parts may cause a rattling noise when the system starts running. Also, debris may enter the outdoor unit and cause a rattling noise when the system runs, particularly at startup.

Consider scheduling regular maintenance services for your ductless system. During a maintenance visit, a comfort advisor will fix loose components and clean all the parts.

Buzzing Noises

Electrical issues may cause a buzzing noise. Other issues that may contribute to buzzing sounds include loose fan blades, dirty condenser coils and a faulty fan motor.

Grinding Noises

Your ductless system has multiple moving components. These components rotate smoothly with the help of lubrication. When the lubrication is insufficient, you may hear grinding sounds due to increased friction.
