The GREE Multi21 Dual-Zone Ceiling Cassette 42,000 BTU System is powered by GREE's energy efficient G10 inverter and a Variable Speed compressor. These units can heat and cool 2 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.

GreeÌs Multi 21 Ceiling Cassette will inconspicuously provide quiet performance through innovative design. The Multi 21 Ceiling Cassette is extremely suitable for any room, and can be easy installed in suspended ceilings with only a discreet decorative discharge grille visible. GreeÌs fan technology quietly and evenly distributes conditioned air throughout the room, and an internal condensate pump reliably disposes condensate water to a safe location. The Multi 21 Ceiling Cassette is ideal for light commercial applications which require comfort control in large, open spaces. Each Multi 21 Ceiling Cassette can be operated by an infrared remote control or wired tether controller, allowing maximum flexibility for any application.

Which line set kit do I need?
This system uses (1) 1/4" x 1/2" line sets and (1) 3/8" 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.
