About this product

The MRCOOL® EasyPro® 18K BTU 230V Ductless Mini-Split Heat Pump Air Handler delivers powerful, energy-efficient heating and cooling for spaces up to 800 square feet. Ideal for garages, basements, workshops, and bonus rooms, it provides reliable year-round comfort while helping control energy use and operating costs. Designed for easy DIY installation, the system is compatible with the MRCOOL® Quick Connect® line sets, which come factory pre-charged with environmentally friendly R-454B refrigerant. This factor totally eliminates the need for vacuum pumps and refrigerant handling, making it easy for homeowners to install. The included 13-foot DIYPRO® cable replaces traditional electrical conduit, simplifying installation while protecting wiring from moisture, pests, and everyday wear. Comfort control is simple using the wireless remote or the MRCOOL® Comfort app, which allows temperature adjustments, scheduling, and energy monitoring from anywhere. Compatibility with Amazon Alexa and Google Assistant adds hands-free convenience. Features like Dry Mode, Sleep Mode, Auto Mode, and programmable scheduling automatically balance comfort and efficiency. A Gold Fin® condenser coating enhances corrosion resistance for long-term durability in humid or coastal environments. For added peace of mind, the MRCOOL® EasyPro® includes a 5-year compressor warranty and a 3-year parts warranty. This strong, industry-leading coverage demonstrates the confidence and pride MRCOOL has in the reliability and performance of every unit.
