The MRCOOL DIY 5th Gen 36,000 BTU Dual Zone Mini Split is an ideal heating and cooling solution for homeowners who desire personalized, energy-efficient comfort in two 800-square-foot spaces without the need for professional HVAC installation.
This dual-zone mini-split AC heat pump system offers year-round comfort while keeping both installation and operating expenses low.
Key Features and Benefits of the MRCOOL Dual-Zone DIY 5th Gen Mini Split
- Two Independent Zones: Two 18,000 BTU air handlers provide personalized comfort, allowing for individual temperature settings in bedrooms, offices, or living spaces.
- High Efficiency: This system uses DC inverter technology to dynamically adjust its output, ensuring consistent comfort while reducing energy consumption in both cooling and heating modes. It boasts a 23 SEER2 and 12 EER2 for cooling, and a 9.9 HSPF2-4 and 7.5 HSPF2-5 for heating.
- Superior Low-Temp Performance: Equipped with low-ambient heating and cooling, this system provides comfort in all four seasons, even in extreme temperatures as low as -13 degrees F.
- Smartphone Control: Control settings, schedules, and monitor performance remotely via the MRCOOL app, Amazon Alexa, or Google Assistant.
- Gold Fin Protection: The outdoor condenser features a protective coating designed to resist salt and moisture. This enhances the system's longevity, especially in humid or coastal areas.
- Smart Alerts: With built-in sensors to detect refrigerant loss and automatic resumption after power outages, the system protects both comfort and equipment.
- Follow Me Sensor: The handheld remote accurately measures the temperature at your current location, rather than relying solely on the wall unit. This ensures the elimination of uncomfortable hot and cold spots.
Note: This system requires two MRCOOL DIY 5th Generation 1/4 x 1/2" Line Sets (Not Included).
Faster Comfort, Lower Costs
The MRCOOL 5th Gen DIY series offers a simplified installation process, unlike traditional air conditioners that demand specialized tools, vacuum pumps, and licensed installers.
Installation is simple: route the required line set through the wall, tighten the flare connections with the provided wrench, and the system is ready for power. Most customers can complete the installation in a single weekend, saving money on professional installation fees (which can be as much as half the system's cost) and avoiding scheduling delays.
