I am not happy with Panasonic air conditioner. Although the cooling is good but heating is dreadful. The vertical swing does not work in heat mode and only pumps out the warm air which is not enough in this cold weather.my relatives have general inverter and they are far better than this inverter. Many of the time it stop working many technician visit numerous time to get it working again over the year now the timer light is blinking to tell me that it need to be repair again what a piece of junk it is.
