The MRCOOL® DIYM255HPW01D00 is a powerful 55,000 BTU 6-zone DIY® mini split system designed for homeowners who want true whole-home comfort without paying for professional HVAC installation. Powered by the MRCOOL® DIY® 5th Generation Multi-Zone condenser, this system delivers efficient heating and cooling to up to six separate rooms using advanced inverter technology and eco-friendly R-454B refrigerant.

This bundle pairs the DIY-MULTI6-55HP230D-O condenser with a 9,000 BTU wall-mounted air handler and a 36,000 BTU wall-mounted air handler, giving you flexible zoning for mixed room sizes. Thanks to DIY® QuickConnect® pre-charged line sets, installation is faster, cleaner, and requires no vacuum pump, gauges, or refrigerant handling. The included DIYPRO® cable eliminates the need for conduit while adding protection against outdoor elements and rodents.

Comfort control is effortless with the MRCOOL® Smart HVAC Controller®, allowing you to manage temperatures, schedules, and energy use directly from your phone. Voice control through Amazon Alexa and Google Assistant comes built-in. With features like Follow Me® temperature sensing, Gold Fin® corrosion protection, and industry-leading warranties, this system is built for long-term reliability and everyday comfort.
