Hi Friend, Panasonic is a brand company and its service is very good. Panasonic makes various types of electronic items like mobile, TV, Cooler, Air conditioner etc. Friend we use various product of different companies but you should use Panasonic product like air conditioner. One time use it and look its effective performance.The company was founded in 1918 and become one of the largest Japanese electronics producer. I use Panasonic AC which are performing better. So use it.
Thanks.
