  • Compact 11.5ft Line Set: Optimized for "back-to-back" installations, the included 11.5ft pre-charged line set is the perfect length for mounting an indoor air handler directly opposite the outdoor condenser on an exterior wall, minimizing clutter and simplifying the install.

  • High Performance: Powered by the latest R-454B refrigerant, the Select series is future-proofed for environmental regulations and offers excellent SEER2 ratings for low monthly energy bills.

  • Smart Control Anywhere: Features built-in Wi-Fi compatibility, allowing you to adjust temperatures, set schedules, and monitor performance through the MRCOOL SmartHVAC app, Amazon Alexa, or Google Assistant
