PL5 delivers efficient comfort at 16-SEER2, with 3-ton and 5-ton options and a fully modulating inverter drive to precisely match heating and cooling loads. It uses R-454B refrigerant (A2L) for lower global warming potential. Quiet operation is achieved through silent blade technology, sound-isolating mounts, and optimized outdoor condenser placement. Intelligent control automatically adjusts output to your setpoint, and four-stage fan control helps reduce humidity. The system ramps smoothly to avoid energy spikes, delivering steady performance and a fast response for reliable year?round comfort.
