Ductless air conditioners do an excellent job of keeping homes cool. However, like any HVAC system, issues can arise. Whether you hear hissing or grinding noises, knowing what to do when your ductless AC system in Kingsland, GA, is loud is essential to fixing the problem correctly.
Grinding in the Ductless AC System
The air handlers in your ductless system contain greased bearings. These bearings reduce the amount of friction the ductless AC system experiences as it operates. Over time, however, the oil can deteriorate, causing increased wear and tear on the bearings.
Without new grease, friction between the bearings and the motor housing increases. If left unaddressed, you’ll hear this friction—resulting in a grinding sound. Loose, broken, or worn-out parts can also cause this noise, so it’s best to turn off your ductless AC system and contact a service technician.
Hissing in the Ductless AC System
Hissing noises from a ductless AC system are a sign that there are air bubbles in the refrigerant line. This also indicates a leak in the system, which can decrease the ductless air conditioner’s performance and energy efficiency.
With low or no refrigerant, the ductless AC system will struggle to absorb and release heat as needed to cool your home. This is another noise issue that requires immediate attention from a trained HVAC service technician.
Short-Cycling Ductless AC System
Short-cycling occurs when your ductless AC system continuously turns itself on and off. The noises you may hear when a ductless air conditioner short cycles include clicking, buzzing, humming, rattling, squealing, popping, or banging.
Causes of short-cycling range from a faulty thermostat to compressor issues. If you notice your ductless AC system short-cycling, the best step is to seek help from a service technician as soon as possible.
