Product Description 

Model: DIYM255HPW05D00

The MRCOOL® DIYM255HPW05D00 is a powerhouse 55,000 BTU 6-zone DIY® mini split system designed for large homes, multi-room layouts, and demanding comfort applications where balanced airflow and independent zone control are essential. Powered by the MRCOOL® 5th Generation double-stack DIY® condenser, this system delivers exceptional heating and cooling efficiency using next-generation R-454B refrigerant, ensuring long-term performance and regulatory compliance.

This configuration features two 24,000 BTU wall-mounted air handlers, making it ideal for larger bedrooms, living areas, workshops, basements, or multi-purpose spaces that require strong, consistent climate control. Installation is made homeowner-friendly through DIY® QuickConnect® pre-charged line sets, eliminating the need for vacuum pumps, gauges, or professional refrigerant handling. The included DIYPRO® cable further streamlines installation by removing conduit requirements while protecting system communications from moisture, UV exposure, and pests.

Once installed, the system integrates seamlessly with the MRCOOL® Smart HVAC Controller®, giving you full control of each zone from your smartphone. Create schedules, fine-tune temperatures, monitor energy usage, or operate hands-free using Amazon Alexa or Google Assistant. Premium comfort features such as Follow Me® temperature sensing, Gold Fin® corrosion-resistant coils, and ultra-quiet inverter operation make this system a long-term comfort investment built for real-world living.

This is a true DIY® multi-zone heat pump solution that delivers contractor-grade results, energy savings, and scalability—without contractor pricing.
