Ductless air conditioners do a great job at keeping homes cool. Like with any HVAC system, though, things can go wrong. Whether it’s a hissing or a grinding sound, knowing what to do when your ductless AC system in Kingsland, GA, is loud is key to fixing the problem correctly.
Grinding in the Ductless Air Conditioner
The air handlers installed in your ductless system have a set of greased bearings. These bearings lower the amount of friction the ductless AC system endures as it operates. However, over time, the oil deteriorates, causing increased wear and tear on the bearings.
Without new grease, the friction between the bearings and the motor housing increases. If left unchecked, you’ll hear the friction — that’s the grinding sound. Loose, broken or worn-out parts can also cause this noise, though, so it’s best to turn off your ductless AC system and call a service technician.
Hissing in the Ductless Air Conditioner
Hissing noises coming from a ductless AC system are a sign there are air bubbles in the refrigerant line. It also means there’s a leak in the system, which can diminish 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 it requires in cooling your home. This is another noise issue that requires immediate attention from a trained HVAC service technician.
Short-Cycling Ductless AC System
Short-cycling is when your ductless AC system continuously turns itself on and off. The noises you might 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. The best thing to do if you notice your ductless AC system short-cycling is to get help from a service technician as soon as possible.
