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

• Two Independent Zones: Place each 12,000 BTU air handler where it matters most, bedrooms, offices, or living spaces, and set individual temperatures for personalized comfort.
• High Efficiency: The DC inverter technology adjusts output in real time, lowering energy use while keeping rooms consistently comfortable in both cooling and heating modes. It cools with a 23 SEER2 rating and a 12 EER2 rating. It heats with a 9.5 HSPF2-4 rating and a 7.0 HSPF2-5 rating.
• Superior Heat Pump Performance: Low-ambient heating and cooling keep spaces comfortable even in extreme weather down to -13 degrees F, making it a practical mini-split heat pump for four-season climates.
• Smartphone and Voice Control: Use the MRCOOL app, Amazon Alexa, or Google Assistant to change settings, set schedules, and monitor performance from anywhere.
• Gold Fin Protection: The outdoor condenser’s protective coating resists salt and moisture, extending system life in coastal or damp environments.
• Smart Alerts: Built-in sensors alert you to refrigerant loss and automatically resume operation after a power outage, protecting both comfort and equipment.
• Follow Me Sensor: The handheld remote checks the temperature where you are, not just at the wall unit,  eliminating hot and cold spots.

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

Faster Comfort, Lower Costs

Traditional air conditioners often require specialized tools, vacuum pumps, and licensed installers, but the MRCOOL 5th Gen DIY series removes those hurdles. Most customers finish the job in a single weekend, avoiding scheduling delays and installation fees that can equal half the system’s price. Because the required linesets are matched and pre-charged at the factory, you also gain confidence that the system will run at peak efficiency from day one.
