The Ruud RD18AY48AJVCA is a 4-ton Endeavor Line heat pump built on the next-generation R-454B (A2L) refrigerant, delivering up to 18 SEER2 cooling efficiency from a variable-speed (iM inverter) compressor. It draws 38 A minimum circuit ampacity on a 40 A max breaker (208-230V / 1-phase / 60Hz), with 3/8" liquid and 7/8" vapor line connections for a straightforward line-set match.
Part of Ruud's low-GWP Endeavor Line, it pairs with Endeavor air handlers, coils, and gas furnaces to hit certified AHRI system ratings. A compact side-discharge cabinet fits tight lots and zero-lot-line installs where a top-discharge unit won't, and its universal-replacement design pairs with nearly any R-454B indoor system, communicating or not. A variable-speed twin-rotary inverter compressor drives it as quiet as 50 dB with the optional sound blanket. Backed by a 10-year conditional parts (with registration).
