The RD18AY24AJVCA is a 2-ton outdoor heat pump designed for residential split systems. It’s well-suited for homes between 900 and 1,200 square feet, offering both heating and cooling in a compact side-discharge format. This unit features a variable-speed inverter compressor, which allows for quieter operation and more precise temperature control. It uses R-454B refrigerant to meet updated environmental standards. The side-discharge design makes it ideal for tight installation spaces, such as zero-lot-line homes or urban settings. Contractors will appreciate its accessible layout and simplified service points. Whether used in new construction or as a system replacement, it pairs easily with compatible indoor air handlers or coils to deliver reliable year-round comfort.
