Whether you’re adding comfort to a small bedroom, home office, or bonus room, this MRCOOL mini-split is a convenient way to achieve year-round comfort.

Key Features and Benefits of the MRCOOL 9,000 BTU 5th Gen DIY Mini-Split

  • Energy Star Certified: Equipped with high-efficiency components, the MRCOOL 9,000 BTU DIY system keeps your utility bills in check while keeping your space perfectly climate-controlled. It boasts a 23.6 SEER2 (Seasonal Energy Efficiency Ratio) and an 11.5 HSPF2 (Heating Seasonal Performance Factor 2) rating.
  • Operation Modes: Use the Sleep function to minimize energy usage at night, turn on the Timer for a specific time during the day, switch to Auto mode to keep the room at your preferred temperature, or activate the Dry mode to remove excess condensation and help reduce humidity.
  • Eco-Friendly Refrigerant: It contains R-454B refrigerant, which has a lower environmental impact than other refrigerants.
  • Gold Fin Condenser: The outdoor condenser has a corrosion-resistant Gold Fin finish. An anti-mildew function reduces excess condensation from the air handler to prevent mold.
  • Active Clean: With the Active Clean function, this model automatically removes dust from the heat exchanger by freezing and quickly thawing the frost. This process produces more condensed water, which improves the cleaning effect and also blows out cold air.

Thanks to a comprehensive installation kit, the MRCOOL DIY lives up to its name with an easy approach to help you install this mini-split system air conditioner without specialized tools or extensive HVAC knowledge.

  • DIYPRO Cable: This cable eliminates the need for electrical conduit, making installation even easier for DIYers and adding durability against animals, yardwork tools, and weather.
  • QuickConnect Line Set: This pre-filled 25-foot-long line set makes set-up safe and straightforward.
  • Complete Installation Kit: This model includes everything needed for installation, including all hardware, pads, seals, caps, sleeves, cables, and tubing.
