I dont understand why people recommend Gree? My office has all gree unties 1.5 ton inverter and actually since i was in procurement at the time, it was me who made the decision buying gree and well to be honest its cooling is really very average and mediocre. 1st floor works a little better but on 2nd floor its really useless. All outdoors are installed in shades, service is done periodically and because of this heat we keep it on 16.
So based on my experience i wouldnt recommend Gree to anyone.
