Info & Guides

The MRCOOL DIY 5th Gen 48,000 BTU Quad-Zone Mini Split offers an affordable and energy-efficient solution for heating and cooling up to five medium-sized rooms. This system provides homeowners with personalized comfort year-round, eliminating the need for professional HVAC installation and reducing both initial setup and ongoing operational costs.

Key Features and Benefits of the MRCOOL Dual-Zone DIY 5th Gen Mini Split

  • Independent Zones: Precisely control the temperature in multiple distinct zones, each up to 400 square feet, with five individual 9,000 BTU air handlers. Every space, from bedrooms to offices and living areas, will enjoy personalized climate comfort.
  • High Efficiency: This system employs DC inverter technology for consistent comfort and significantly reduced energy consumption during both cooling and heating. It boasts impressive efficiency ratings: 21.8 SEER2 and 12 EER2 for cooling, and 10 HSPF2-4 and 7.8 HSPF2-5 for heating.
  • Superior Low-Temp Performance: With both heating and cooling capabilities, this system ensures year-round comfort, even in temperatures as low as -13 degrees Fahrenheit.
  • Smartphone Control: Easily manage settings, schedules, and performance from anywhere using the MRCOOL app, Amazon Alexa, or Google Assistant.
  • Gold Fin Protection: The outdoor condenser is equipped with a protective coating that repels salt and moisture, which prolongs the system's lifespan, especially in humid or coastal environments.
  • Smart Alerts: Built-in sensors detect refrigerant loss, and an automatic restart system activates after power outages. This ensures continuous comfort and protects the equipment.
  • Follow Me Sensor: Enjoy consistent comfort. The handheld remote precisely measures the temperature at your location, eliminating the uneven temperatures often found with traditional wall-mounted units.

Note: This system requires five MRCOOL DIY 5th Generation 1/4 x 3/8 Line Sets (Not Included).
