The MRCOOL® DIYM255HPW00D07 is a high-output 55,000 BTU multi-zone DIY® mini split system engineered for homeowners who want maximum coverage, true DIY installation, and long-term efficiency without paying contractor labor. This bundle is ideal for large homes, barndominiums, workshops, and multi-room layouts where precise zoning and serious capacity matter.

At the heart of the system is the MRCOOL® 5th Generation DIY® 55K 6-Zone condenser, paired with a 6K air handler for smaller precision spaces and a 36K air handler designed for large open areas. Together, they deliver balanced comfort across up to 1,750 square feet, all controlled independently through the MRCOOL® Smart HVAC Controller®.

Thanks to DIY® QuickConnect® technology, factory-sealed R-454B refrigerant, and integrated DIYPRO® cable, installation is straightforward—no vacuum pump, no gauges, no refrigerant handling, and no licensed HVAC technician required. Once installed, control your comfort from anywhere using the SmartHVAC app or hands-free voice control with Amazon Alexa or Google Home.
