The MRCOOL DIY Select 9K BTU Mini Split System gives you dependable heating and cooling with a sleek black indoor air handler that looks cleaner, sharper, and more modern than the usual white wall unit.

With 17.5 SEER2 efficiency, quiet operation, smart control, and true DIY installation, the DIY Select makes year-round comfort easier and more affordable.
The included 11.5 ft pre-charged Quick Connect® line set helps simplify installation by eliminating the need for vacuum pumps, gauges, or refrigerant handling. Mount the indoor unit, connect the pre-charged line set, power on the system, and enjoy reliable comfort on your terms.
