Use this multi-zone system to heat and cool four different spaces in your home or business. The MRCOOL DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System-9k+9k+12k+12k is one of the only multi-zone systems available that you can easily install yourself without expert HVAC help. The outdoor heat pump powering this 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 MRCOOL DIY Ductless Split System is a heat pump by design. So when the appliance heats your home or business， the appliance is reversing the air conditioning process and pulling heat indoors from outside. The 2 9，000 BTU air handlers distribute heated and cooled air effectively in spaces up to around 375 sq. ft. The 2 12，000 BTU air handlers work best in rooms up to 500 sq. ft.
