Description

MRCOOL DIY 5th Gen Multi-Zone 3-Zone 36,000 BTU 23 SEER2 (6K + 6K + 18K) 3×25ft Line Sets Ductless Mini-Split Air Conditioner & Heat Pump DIYM336HPW01D37

The MRCOOL DIYM336HPW01D37 is a high-efficiency 3-zone ductless mini-split system designed for homeowners seeking precise room-by-room comfort, reduced energy costs, and a professional-grade HVAC solution that can be installed without hiring an HVAC contractor.

This complete bundle is powered by the MRCOOL DIY 5th Generation 36,000 BTU multi-zone outdoor condenser, paired with two 6,000 BTU indoor air handlers for smaller rooms and one 18,000 BTU air handler for larger living areas. This configuration is ideal for bedrooms, home offices, guest rooms, bonus rooms, and main living spaces, allowing each zone to operate independently for personalized comfort.

Installation is simplified with DIY QuickConnect pre-charged line sets, which arrive factory-sealed with R-454B refrigerant—eliminating the need for vacuum pumps, gauges, or refrigerant handling. The included DIYPRO communication cable removes the requirement for electrical conduit, making this system one of the most DIY-friendly multi-zone mini-split solutions available.

Featuring DC inverter technology, Gold Fin corrosion-resistant coils, Follow Me temperature sensing, and full Smart HVAC Controller App integration, this system delivers quiet operation, accurate temperature control, and long-term reliability, all backed by industry-leading warranty coverage.
