Product Description 
Model: DIYM255HPW02D00
 
The MRCOOL® DIYM255HPW02D00 is a powerful 55,000 BTU 6-zone DIY® mini split system engineered for homeowners who want full-home comfort, advanced smart control, and professional HVAC performance — without paying professional installation costs. Built around the MRCOOL® DIY® 5th Generation 6-Zone double-stack condenser, this system delivers dependable heating and cooling across multiple rooms using ultra-efficient inverter technology and next-generation R-454B refrigerant.
This bundle pairs a 12,000 BTU wall-mounted air handler for mid-size living spaces with a 36,000 BTU wall-mounted air handler designed for large open areas, basements, workshops, or great rooms. Installation is fast and frustration-free thanks to DIY® QuickConnect® pre-charged line sets, allowing homeowners to skip vacuum pumps, gauges, and refrigerant handling entirely. The included DIYPRO® cable removes the need for electrical conduit while protecting communications wiring from weather and pests.
Once installed, the system connects seamlessly to the MRCOOL® Smart HVAC Controller®, giving you full control from your smartphone. Adjust temperatures by zone, set schedules, monitor energy usage, or control your comfort 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, high-value upgrade over traditional HVAC solutions.
This is a true DIY® multi-zone system built to outperform contractor-installed setups while keeping ownership costs low and efficiency high.
