The GREE Multi21+ Tri-Zone CROWN 36,000 BTU System is powered by Gree’s G10 inverter-driven compressor and eco-friendly R410A refrigerant. These units can heat and cool 3 zones without distribution boxes. Our G10 inverter technology saves energy, reduces outdoor noise and keeps room temperature steady by eliminating the harsh starts & stops of conventional systems. The Multi21+ CROWN is the smartest ductless High Wall unit. Slim compact design, it hangs inconspicuously on the wall and mixes well with most interior designs.

Which line set kit do I need?
This system uses (1) 1/4" x 1/2" line set and (2) 1/4" x 5/8" line set. These are sold separately, and you can choose from our 15 ft, 25 ft, 35 ft, 50 ft, and 75 ft lengths. The length needed depends on the needs of your project and how you will set up the system (distance from outdoor condenser to indoor air handler).

Can I install this myself?
While installation of a ductless split is much easier than a central air system, it's still much more advanced than installing a window unit or portable. Furthermore, the manufacturer warranty is only valid if a licensed professional does the installation. So while it is possible to do the installation yourself, we strongly recommend you hire an HVAC professional in your area.

Is this backed by a warranty?
Yes, it comes fully backed by a manufacturer's warranty, and ComfortUp is an authorized online seller of these systems. Our Customer Care Team will provide assistance should you ever need to file a warranty claim with the manufacturer. Please be aware that only systems that are installed by a licensed HVAC contractor are backed by the warranty. Proof of licensed installation is required. The receipt/invoice from your contractor should be sufficient.
