MRCOOL DIY 42,000 BTU 3-Ton 4-Zone Ductless Mini-Split A/C and Heat Pump 230-Volt/60Hz with 2- 35 ft. 2-50 ft. Line Set

The 4th Generation MRCOOL DIY Multi-Zone 36k BTU 4 Zone Ductless Mini Split is one of the few multi-zone systems available that you can easily install yourself without expert HVAC help. The outdoor heat pump powering the system has a heating capacity of up to 36,000 BTU and is highly efficient with a 21.5 SEER rating. This is thanks in part to the variable speed DC inverter. The two 9,000 BTU air handlers distribute heated and cooled air effectively in spaces around 375 sq. ft. to 450 sq. ft. The two 12,000 BTU air handlers work best in rooms between 500 sq. ft. to 600 sq. ft.
