Product description

Product Description 
Model: DIYM255HPW03D00
The MRCOOL® DIYM255HPW03D00 is a high-capacity 55,000 BTU 6-zone DIY® mini split system designed for homeowners who want full-home comfort, zoning flexibility, and contractor-grade performance—without contractor labor costs. Powered by the MRCOOL® DIY® 5th Generation double-stack 6-zone condenser, this system delivers efficient heating and cooling across multiple rooms using advanced inverter technology and environmentally improved R-454B refrigerant.
This bundle combines an 18,000 BTU wall-mounted air handler—perfect for medium-to-large rooms—with a 24,000 BTU wall-mounted air handler built for expansive living areas, garages, or workshops. Installation is streamlined with DIY® QuickConnect® pre-charged line sets, allowing you to skip vacuum pumps, gauges, and refrigerant handling entirely. The included DIYPRO® cable eliminates the need for electrical conduit while protecting communications wiring from weather and pests.
Once installed, the system integrates seamlessly with the MRCOOL® Smart HVAC Controller®, giving you full control from your smartphone. Set schedules, adjust each zone independently, monitor energy usage, or control your system hands-free using Amazon Alexa or Google Assistant. Features like Follow Me® temperature sensing, Gold Fin® corrosion protection, and industry-leading warranties make this system a long-term investment that outperforms traditional HVAC solutions in both comfort and efficiency.
This is a true DIY® multi-zone heat pump system built to scale with your home, reduce operating costs, and put total comfort control in your hands.
