Ductless mini-split systems are an energy-efficient and effective way to cool your home. These systems operate quietly with minimal noise. Read on and learn about noises you shouldn’t hear that may indicate a need for professional ductless service.
1. Banging and Clanging
Loud banging and clanging sounds coming from your ductless cooling system may indicate a loose part that is moving around and hitting other parts of the system. This could include loose hardware and broken fan blades. This type of noise means that you’ll need professional repairs immediately.
2. Rattles and Vibrations
Rattling and vibrating noises in your ductless unit can also indicate loose parts but might be a sign of debris inside the system. The debris rattles as it blows around and moves against internal components. Our technicians can clean out your ductless system during annual maintenance to prevent these problems from happening.
3. Hissing and Bubbling
Hissing and bubbling noises happen when air gets into the refrigerant lines. Hissing indicates air or refrigerant seeping out of a crack or hole while bubbling means that air is moving through the lines with the refrigerant. Refrigerant leaks are hazardous and require prompt professional attention.
4. Grinding
Loud grinding noises inside your ductless mini-split system may mean that you have parts rubbing against each other. Grinding sounds might also be the result of dry or damaged bearings. Our service techs lubricate bearings and other moving parts to prevent this type of malfunction.
