  • Efficient cooling at temperatures from 5 F to 129 F
  • Horizontal discharge condenser provides a smaller and quieter footprint

3 Ton, 18 SEER

With an output of 3 tons, the Gree Flexx FLEXX36HP230V1AO / FLEXX36HP230V1BH is suitable to cover an average-sized house in ideal conditions. At 18 SEER, this Gree Flexx unit is much more efficient than a standard split central system. Please note that in order to function, Gree Flexx units require a line set, thermostat, and other accessories to install and operate, which are available at an additional cost.


Gree offers a 5 year parts and compressor warranty for installations that follow the installation location's state and local codes and is registered online through the manufacturer.

Versatile Installations

From pre-existing all-electric central setups to new constructions, the Gree Flexx FLEXX36HP230V1AO / FLEXX36HP230V1BH can be installed in almost any type of installation. The unit can either be controlled by Gree-specific wired controllers or any 24V thermostat that you already have or would prefer to use. This would allow you to connect it to any top of the line smart thermostat all the way down to an older basic thermostat, as long as it has two heating connections it will work for this system.
