The DIY 4th Gen Multi-zone Mini-Split MRCOOL kits have everything you need to get started, from condensation drains to templates to air handler wall bracket bracketing.

The MrCool DIY 18K BTU Ductless Heat Pump Condenser, 4th Generation, is one of the most capable heat pumps on the market.

When paired with appropriate MrCool air handlers, this condenser may produce a highly effective 22 SEER efficiency rating. It can also provide heating performance at temperatures as low as -13°F. Its Gold Fin condenser coating ensures that it will survive the elements.

MrCool is the only manufacturer to give a limited lifetime compressor warranty, emphasizing the high quality of this condenser. The flexibility of this heat pump to be a Do-It-Yourself project for a homeowner is its cornerstone.

The refrigerant pipe can be connected with simple hand tools and does not require the services of a certified technician when used with MrCool's proprietary Pre-Charged Quick Connect Line Set. Each one is pre-charged with the correct amount of R-410A refrigerant and does not require vacuuming once installed, which makes connecting refrigerant piping as simple as turning a few wrenches.

You can buy line sets and couplers here.

It is also quite adaptable, with numerous operating modes including COOL, HEAT, AUTO, DRY (dehumidify), and SLEEP. This unit can also be operated by your Apple or Android smartphone via the Smart HVAC app. Its light and small design allow it to be readily fitted to most interior walls using the provided mounting plate.

Allow the capability, performance, and simplicity of a DIY installation of the 4th Generation MrCool DIY 18K BTU Multizone Mini-split to be your sole option for heating and cooling in your home.


Standard 7-year compressor/5-year parts warranty, register for limited lifetime compressor warranty.
