WORST WORST AND WORST SERVICE. I have a 1.5 ton Blue Star AC. Believe me the AC is very good . But recently I called company for a service and from almost 15 days they don’t attend only . I think this company has the worst service and customer care promises you that the engineer will call and they gave me Kool Wind Engineers number and they don’t bother to pick your call. You buy this AC and if it has any problems, you are in trouble, think before you buy a BLUE STAR AC..service requires not even a single star..
