MRCOOL DIY Mini Split - 42,000 BTU 4 Zone Ductless Air Conditioner and Heat Pump

The 4th Generation MRCOOL® DIY 42K BTU 4-Zone Ductless Heat Pump offers state-of-the-art heat pump technology. With the capability to support up to 4 zones and a SEER efficiency rating of up to 21.5 when paired with select MrCool air handlers, this condenser is one of the most innovative options available.

In addition, it can provide heat even in temperatures as low as -13°F and is coated with Gold Fin to resist corrosion and withstand the elements. MrCool also offers a limited lifetime compressor warranty, showing their commitment to quality and durability.

What sets this condenser apart is its unique feature that allows homeowners to install it without the need for a certified technician. This is made possible by using MrCool's patented Pre-Charged Quick Connect Line Sets, which come precharged with R-410A refrigerant and can be easily connected using only wrenches. Since it is pre-charged, there is no need.

Designed for use with MrCool's patented Pre-Charged Quick Connect Line Sets, this DIY heat pump is specifically engineered to work with ease and efficiency.

Please be reminded to include linesets as they are not included in this package. Kindly scroll up to add them.

    Square Feet: 180-375 | BTU = 9K
    Square Feet: 376-500 | BTU = 12K
    Square Feet: 501-750 | BTU = 18K

    Note about condenser sizes vs total of air handler capacity: The total capacity of the combined air handlers may exceed the capacity of the condenser in some configurations. While this provides more flexibility in your setup you will need to either shut off one of your air handlers (zones) or reduce the output of all zones.
