Product Description
LG furnaces deliver rated 96% AFUE (Annual Fuel Utilization Efficiency) performance with a compact, multi-position design that allows for flexible installations. These furnaces are intended to operate compatibly with LG Outdoor Units and A-Coils. Each model utilizes ECM constant-airflow motors for consistent air delivery and energy-efficient operation. A factory-supplied NG-to-LP (natural gas to liquid propane) conversion kit and dual-fuel capability when paired with LG Inverter Heat Pumps provides flexibility across a wide range of applications.
