The growing pollution and global warming, has made air conditioners practically an insuperable part of our lives. As per a recent stat it is believed that in India each year approx. 7 million units of ACs are sold, comprising of various leading and small brands. These are first hand new units sold not considering the second-hand sales or used units sold. No matter which brand air conditioner you install, how much ever costly, regular servicing is a must for these to function and remain in a good condition for a considerable time period.
