MRCOOL DIY Mini Split - 45,000 BTU 2 Zone Ductless Air Conditioner and Heat Pump with 50 ft. Install Kit, DIYM248HPW02C32

The MRCOOL DIY Mini Split 45,000 BTU 2 Zone system with a 50 ft. install kit offers a flexible, efficient, and easy-to-install heating and cooling solution for homes, garages, workshops, and more. This 4th Gen DIY system allows for reliable multi-zone climate control with extended line set length to accommodate larger or more complex installations.

Efficient and Durable Condenser

The 48,000 BTU condenser provides strong performance with a 20.5 SEER2 and 8.5 HSPF-5 rating, delivering energy-efficient operation that helps lower utility costs. The Gold Fin® condenser coating guards against corrosion and environmental damage, ensuring long-lasting durability. This unit maintains reliable heating even when outdoor temperatures drop to 5°F. The system includes a 7-year compressor warranty and a 5-year parts warranty for peace of mind.

Versatile Air Handlers for Different Room Sizes

This 2-zone system includes two air handlers designed for various space needs:

  • 9,000 BTU Air Handler: Best suited for smaller rooms between 180 and 375 square feet, such as bedrooms or offices.
  • 36,000 BTU Air Handler: Designed for large rooms from 1,001 to 1,500 square feet, ideal for open-concept or larger spaces.

Both air handlers offer multiple modes—COOL, HEAT, AUTO, DRY, and SLEEP—providing customizable comfort throughout the year. Their compact, lightweight design allows for quick and easy installation. The SmartHVAC app compatibility lets users control the system remotely for added convenience.

Easy Installation with Extended 50 ft. Pre-Charged Quick Connect Line Sets

MRCOOL’s patented Pre-Charged Quick Connect Line Sets simplify installation by removing the need for vacuum pumps or special tools. Each line set is pre-filled with R-410A refrigerant for fast, hassle-free setup. The 50 ft. install kit provides maximum reach, making it suitable for larger homes or buildings with greater distance between condenser and air handlers. Coupler kits are available to extend line sets further if needed. This design reduces labor time and installation costs.

Key Features
  • DIY-Friendly: Pre-charged quick connect line sets reduce installation complexity and labor expenses.
  • Energy Efficient: High SEER2 and HSPF ratings help lower operating costs.
  • Durable: Gold Fin® coating and solid warranties ensure long-term reliability.
  • Smart Control: Manage the system remotely via SmartHVAC app.
  • Flexible Coverage: Two air handlers cover a broad range of room sizes for tailored comfort.
