MRCOOL DIY Mini Split - 42,000 BTU 4 Zone Ceiling Cassette Ductless Air Conditioner and Heat Pump with 50 ft. Install Kit, DIYM448HPC02C194

Elevate your climate control game with the MRCOOL 4th Gen DIY Mini Split system—an innovative, reliable, and energy-efficient solution designed to keep multiple rooms perfectly comfortable year-round. Whether you’re outfitting a home, garage, workshop, or commercial space, this 4-zone system offers powerful performance combined with effortless installation. Best of all, it’s engineered for you to handle the setup yourself, saving you time and costly technician fees while delivering professional-grade results.

High-Capacity, Energy-Efficient Condenser

At the heart of this system is a robust 48,000 BTU condenser built to deliver consistent heating and cooling with exceptional energy savings. Featuring a 20.5 SEER2 and 8.5 HSPF-5 rating, this unit keeps operating costs low without sacrificing performance. The Gold Fin® condenser coating protects against corrosion and wear, ensuring long-lasting durability even in tough environments. When winter hits, rely on this condenser to provide steady warmth down to 5°F outdoor temperatures. Backed by a 7-year compressor warranty and 5-year parts warranty, it offers peace of mind for both installers and end users.

Versatile Ceiling Cassette Air Handlers for Customized Comfort

This system includes two sizes of MRCOOL’s OuttaSight ceiling cassette air handlers, designed to fit discreetly between standard 16” ceiling joists, creating a clean, modern look that doesn’t intrude on your space:

  • 9,000 BTU Air Handler: Ideal for smaller rooms from 180 to 375 square feet, perfect for bedrooms, offices, or compact workshops.
  • 12,000 BTU Air Handler: Designed for medium-sized spaces between 376 and 500 square feet, delivering balanced comfort without ductwork.

Both units integrate seamlessly with the DIY 4th Gen Multi-Zone system, allowing you to tailor climate control for each zone independently. The SmartHVAC app puts full control in your hands, enabling easy adjustments from anywhere using a smartphone or tablet.

Installation Made Effortless with Pre-Charged Quick Connect Line Sets

MRCOOL’s patented Pre-Charged Quick Connect Line Sets take the complexity out of installation. Pre-filled with R-410A refrigerant, these copper line sets connect quickly and securely without the need for vacuum pumps or specialized tools. Each indoor unit connects with its own dedicated line set, ensuring optimal performance and reliability. Need to extend your reach? The included coupler kit lets you join two line sets seamlessly, giving you the flexibility to cover any space.

Frequently Asked Questions about MRCOOL DIY Mini Split - 42,000 BTU 4 Zone Ceiling Cassette Ductless Air Conditioner and Heat Pump with 50 ft. Install Kit, DIYM448HPC02C194

Most Frequently Asked Questions

Yes, MRCOOL DIY mini splits are generally well-regarded for their easy installation, reliable performance, and energy efficiency, making them a popular choice for homeowners looking for a do-it-yourself HVAC solution.

A MRCOOL mini-split typically lasts 10 to 20 years with proper installation and regular maintenance

The cost to install a MRCOOL mini-split system typically ranges from $3,000 to $10,000, depending on the size, number of zones, and installation complexity, with DIY installation potentially saving $500 to $2,000 in labor costs

Other Questions

It's generally more energy-efficient to leave your mini split running at a consistent, moderate temperature during the summer rather than turning it off and on frequently, as mini splits use inverter technology to adjust cooling output smoothly and avoid the energy spikes of restarting.

Mini splits are generally energy-efficient for heating because they use heat pump technology, which transfers heat rather than generating it by burning fuel or using resistance coils. This means they typically use less electricity than traditional electric heaters, though actual electricity use depends on factors like outdoor temperature, system size, and insulation.
