Info & Guides

The MRCOOL DIY Select 9,000 BTU Ductless Mini-Split Heat Pump gives you year-round heating and cooling for rooms up to 400 square feet, all on a standard 110-120V household circuit. Designed for true do-it-yourself installation, this single-zone wall-mount system puts climate control in your hands without a contractor.

Detached garages, home offices, sunrooms, and indoor grow rooms all benefit when traditional ductwork is not an option. The pre-charged 11.5-foot line set ships ready to connect, so you can have the system running without specialized HVAC tools or refrigerant handling.

Key Features and Benefits of the MRCOOL DIY Select 9,000 BTU Ductless Mini Split Heat Pump

Inverter Compressor: The variable-speed inverter rotary compressor adjusts output to match your set temperature, reducing energy waste compared to fixed-speed systems.
SEER2 Efficiency: A 17.5 SEER2 efficiency rating means lower electricity costs during both heating and cooling seasons.
Heating and Cooling: With 9,000 BTU in both heating and cooling modes, this system keeps your space comfortable across a wide outdoor temperature range.
Included Line Set: The 11.5-foot, 1/4 x 3/8-inch line set comes pre-charged with R-454B refrigerant, eliminating the need for vacuum pumps or refrigerant charging during setup.
DIY Installation: A 110-120V connection and step-by-step instructions let you install the system without hiring an HVAC contractor.
Remote Control: The included remote control lets you adjust temperature, fan speed, and operating mode from across the room.
Wi-Fi Capable: Connect to your home Wi-Fi network and manage temperature settings through the smartphone app, even when you are away.
Variable-Speed Technology: Rated for higher than average efficiency, the variable-speed compressor holds tighter temperature tolerances to help you maintain consistent conditions.
Certified Safety: ETL listed, AHRI certified, CSA certified, and UL listed, confirming that every safety and efficiency claim has been independently verified.

Sized to Run Efficiently

At 9,000 BTU, the DIY Select is rated for rooms up to 400 square feet, well-suited for bedrooms, home offices, sunrooms, and single-car garages. The 17.5 SEER2 efficiency rating keeps operating costs manageable at this capacity, and the 110-120V power requirement means a standard household outlet is all you need. For grow room setups, the variable-speed compressor holds tighter temperature tolerances than single-stage systems, giving you more precise environmental control.

Sylvane's Expert Take

If you are a homeowner looking to add heating and cooling to a single room or detached space without hiring an HVAC contractor, the MRCOOL DIY Select is built for you. The pre-charged 11.5-foot line set and standard 110-120V power let you handle the full installation yourself, setting this system apart from most ductless splits that require professional refrigerant charging and electrical work. The inverter compressor modulates output instead of cycling on and off at full power, holding your set temperature with minimal swing, which means steadier comfort and lower monthly energy bills.
