Bought haier 1.5 ton split ac last year . It was sooth and great experience for about 1 year but now I feel as if the cooling pattern are irregular . SOmetime I feel as if the cooling is ok and some other day I feel as if the cooling has declined significantly . I dont know what is the issue with this. It even blows ice wind with smoke sometimes as if there is some gas leakage . I m disappointed with he product .
