I invested in this AC a few years ago. It was a horrible experience. The very first thing that happened was that the gas leaked within 2 days. They installed the AC incorrectly. The Customer service was extremely poor.The Customer service was extremely poor. The Company denied an exchange and I was at my wits end. The cooling was horrible. At 22 degrees, the room would hardly feel a little less warm. We had to put on the fan along with the AC till we could afford another AC of a different brand.
