I m using this product since two year. 1.5 ton splt a.c. cools our 15'x 14'room instantly even in 45?. Some I have to off my a.c. its best specifiaction is its mantain blower speed at number of person in room. Low power consuption and gives us better cooling perfomence. Guys my persnol experience with lloyd that using thus product is no waste of money. As its turn on it stats cooling. And automaticly slow its blower or cooling speed. This fucntion makes it best a.c. it bear fructuation on power. Thank for team lloyd
