Experience versatile and efficient year-round comfort with the MRCOOL DIYM248HPW02D00 48K DIY Multi-Zone Mini Split Bundle. Designed for homeowners who want to customize comfort without professional install costs, this advanced dual-zone mini split system delivers powerful cooling and heating to two distinct spaces — from cozy bedrooms and home offices to large open living areas and finished basements. Built on MRCOOL’s robust 48K 6-Zone Double Stack outdoor condenser, this bundle gives you room to grow with four additional unused ports for future expansion.

Each wall-mounted air handler is engineered for quiet, efficient operation. The 9,000 BTU unit is ideal for smaller rooms up to approximately 350–400 sq ft, while the 36,000 BTU unit is more than capable of keeping larger areas between 1,200–1,550 sq ft comfortable. Both units feature whisper-quiet performance, smart controls via the included remotes, and intuitive SmartHVAC WiFi compatibility for easy temperature management.

Installation is truly DIY-friendly, thanks to MRCOOL’s signature pre-charged Quick-Connect® line sets that eliminate the need for vacuum pumps or refrigerant handling. Simply connect the line sets, power the units, and begin enjoying personalized climate control tailored to your lifestyle.

This system is perfect for homeowners seeking energy efficient, modular comfort solutions that can adapt as needs evolve. With future zone flexibility, smart app integration, and high-performance cooling and heating, this MRCOOL bundle delivers value and convenience in one complete package.
