Installation is further simplified with an 11.5-foot Quick Connect® line set that arrives factory pre-charged with environmentally friendly R-454B refrigerant, eliminating the need for vacuum pumps or refrigerant handling. Most components are included, making setup faster and more approachable for first-time installers. Comfort control is easy using the included wireless remote or the MRCOOL® Comfort app, which allows remote temperature control, scheduling, and energy monitoring. Compatibility with Amazon Alexa and Google Assistant adds hands-free convenience. Features like Sleep Mode, Dry Mode, Auto, and a Gold Fin® condenser coating enhance comfort and durability, even in humid or coastal environments.
