MRCOOL® 27K 4-Zone DIY® Mini Split System with two 6K + 12k Air Handlers & one 16ft + two 25ft QuickConnect® Line Sets- R-454B- DIYM327HPW02D06

Product Description 

Model: DIYM327HPW02D06

The MRCOOL® DIYM327HPW02D06 is a highly flexible 27,000 BTU 4-zone DIY® mini split system designed for homeowners who want professional-grade comfort without paying for professional installation. Powered by the MRCOOL® 5th Generation DIY® multi-zone condenser, this system delivers efficient, quiet, and reliable heating and cooling using modern R-454B refrigerant.

This configuration includes two 6,000 BTU wall-mounted air handlers and one 12,000 BTU air handler, making it ideal for bedrooms, home offices, nurseries, bonus rooms, or shared living spaces that require a little more capacity. Each zone operates independently, giving you precise temperature control while reducing energy waste.

Installation is simplified by MRCOOL® DIY® QuickConnect® pre-charged line sets, which eliminate vacuum pumps, gauges, and refrigerant handling. The included DIYPRO® cable removes the need for electrical conduit and protects communication wiring from the elements. Long-term durability is enhanced by Gold Fin® corrosion-resistant coils, making this system well-suited for humid and coastal climates.

Once installed, full system control is available through the MRCOOL® Smart HVAC Controller®. Adjust temperatures, create schedules, monitor energy usage, or use hands-free voice control with Amazon Alexa or Google Assistant. Comfort-focused features like Follow Me® temperature sensing, inverter-driven operation, and ultra-quiet performance make this system a long-term upgrade, not just a replacement.
