Dear folk, I use the Hair HSU 12CA2 AC for my bedroom having capacity of 1 ton.When I purchased this product I thought that I brought the right product but now my decision is wrong.This ac gives many shortcomings time to time, its outlet vent is sudden jam and air exhaustion is stopped for five to six second. Ac cooling performance is also reduce when no of people increases in room.So guys, I suggest you if you want to use trouble free service than you used another brand ac but don’t try to buy this.
