Unusual noises indicate that your ductless mini split is running inefficiently, and you should seek a technician’s services. Different sounds indicate various issues. Below, we will discuss some ductless system noises in Marietta, GA and what they mean.
Your ductless system has multiple moving components, which require lubrication to eliminate friction as they come in contact with other parts. Lubrication minimizes wear and tear, in turn reducing the amount of repairs your system might need.
Grinding noises mean that the moving parts don’t have enough lubrication. Consider scheduling regular maintenance services to keep your system’s components well-lubricated.
A constant rattling noise indicates there is a loose part in your system. Loose components may damage other pieces of your system, such as fan blades, when they collide. Addressing this issue early helps to avoid you needing to repair multiple damaged components, thus saving you money on repair costs.
Hissing and Gurgling
A refrigerant is fluid in your ductless mini-split that moves heat from the indoor unit to the outdoor unit when your system is in cooling mode. The compressor increases and decreases the pressure of this fluid to enable it to move heat from one area to another. When the high-pressure fluid attempts to escape through tiny punctures in the refrigerant lines, you will hear a hissing noise.
A gurgling sound occurs when air enters the refrigerant lines through these openings. Like many other HVAC problems, you should leave fixing hissing/gurgling noises to professionals, as refrigerant can be harmful to your health and the environment.
Buzzing noises arise from electrical issues within the system. To avoid the risk of electrocution, seek the services of a professional technician to take care of electrical issues.
