It uses a piston-driven design to draw in low-pressure refrigerant vapor and discharge it at high pressure, driving heat transfer through the condenser and evaporator so your system delivers its rated cooling output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e no cooling despite the fan running, the compressor hums but won't start, repeated breaker or overload trips, loud knocking or rattling, excessive heat, or short-cycling.
