Lioyd air conditioner is product of voltas and I am using this since I was 18 year old .my father bought this and just few years before and it is good to use having many mode like fan cooling sleep and dry mode.Carrier ac is installed in a 15x11 sq ft room and it lowers the temperature to 24C in about 20 mins in peak summer but I always thought that due to the fast cooling.it comes in many variety like 3 star to five star rating and in tone also 1 to 5 tone.my father bought 3 star rating air conditioner which is affordable for my family.it switches one mode to other in less time and make us happy.it has less in size and fit in any where.
