Product Description 
Model: DIYM255HPW01D07
The MRCOOL® DIYM255HPW01D07 is a premium 55,000 BTU 6-zone DIY® mini split system engineered for homeowners who want full-home comfort, smart control, and professional-grade performance — without paying for professional installation. Built around the powerful MRCOOL® DIY® 5th Generation 6-Zone condenser, this system efficiently heats and cools up to six separate areas using advanced inverter technology and environmentally friendly R-454B refrigerant.
This bundle combines the DIY-MULTI6-55HP230D-O double-stack condenser with a 9,000 BTU wall-mounted air handler for smaller rooms and a 36,000 BTU wall-mounted air handler for large open spaces. Installation is made simple 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 conduit while adding extra protection against weather and pests.
Once installed, you’re in full control using the MRCOOL® Smart HVAC Controller®. Adjust temperatures, set schedules, and monitor energy use directly from your smartphone, or go hands-free with Amazon Alexa and Google Assistant. Features like Follow Me® temperature sensing, Gold Fin® corrosion protection, and industry-leading warranties make this system a long-term investment in comfort, efficiency, and peace of mind.
This is a true DIY® multi-zone solution designed to outperform traditional HVAC systems while keeping installation costs low and efficiency high.
