Product Description 

Model: DIYM255HPW05D06

The MRCOOL® DIYM255HPW05D06 is a high-capacity 55,000 BTU 6-zone DIY® mini split system engineered for large homes, open-concept floor plans, workshops, and multi-room properties that demand serious, balanced comfort. At the heart of the system is the 5th Generation MRCOOL® DIY® double-stack condenser, delivering powerful heating and cooling while maintaining outstanding energy efficiency with next-generation R-454B refrigerant.

This bundle includes two 24,000 BTU wall-mounted air handlers, making it ideal for large living spaces, master suites, finished basements, garages, or commercial-style residential applications. Installation is truly homeowner-friendly thanks to DIY® QuickConnect® pre-charged line sets, which arrive factory-sealed and eliminate the need for vacuum pumps, gauges, or licensed HVAC labor. The included DIYPRO® cable further simplifies installation by removing conduit requirements while protecting system communications from moisture, UV exposure, and pests.

Once installed, comfort control is effortless. The system integrates with the MRCOOL® Smart HVAC Controller®, allowing full zone-by-zone control from your smartphone. Adjust temperatures, set schedules, monitor energy usage, or operate hands-free using Amazon Alexa or Google Assistant. Premium features like Follow Me® temperature sensing, Gold Fin® corrosion-resistant coils, and ultra-quiet inverter technology make this system a long-term comfort solution built to outperform traditional HVAC systems.

This is contractor-grade performance designed for true DIY® installation—powerful, expandable, and built to last.
