Product details
The MRCOOL® DIY® Select 9K BTU 115V Ductless Mini-Split Heat Pump Air Handler delivers efficient, reliable heating and cooling for spaces up to 400 square feet. Ideal for bedrooms, home offices, garages, and bonus rooms, this system provides year-round comfort while helping reduce energy usage and monthly utility costs.
Built as part of the MRCOOL® DIY® lineup, this unit is engineered for true do-it-yourself installation with the help of the compatible Quick Connect® line sets. These line sets arrive factory pre-charged with environmentally friendly R-454B to remove the need for vacuum pumps or refrigerant handling. Meanwhile, the included 13-foot DIYPRO® cable eliminates the need for traditional electrical conduit, simplifying installation while protecting wiring from moisture, pests, and everyday wear.
Comfort control is easy and flexible using the included wireless remote or the MRCOOL® Comfort app, which allows you to adjust temperatures, create schedules, and monitor energy use from anywhere. Voice-control compatibility with Amazon Alexa and Google Assistant adds hands-free convenience.
Dry Mode, Sleep Mode, Auto Mode, and programmable scheduling improve comfort and efficiency, while the Gold Fin® condenser coating delivers added corrosion resistance for long-term durability in humid or coastal climates.
For added peace of mind, the MRCOOL® DIY® Select 9K includes a 2-year compressor warranty and 1-year parts warranty.
