Hey guys I am here for sharing my personnel experience with voltas 183. I bought voltas 183 in 2014. Ac was lil bit good but takes so much time for cooling a whole room. Ac was 4 star dealer told me it is good for energy saving but it take so much energy. Even ac makes with silver not with copper Which is not for long life. Outdoor was very small. Tata is a very big brand even they makes best ac’s everytime I am not satisfied with Voltae 183. I just sell this ac because of so many problems. So overall it was my bad experience with voltas 183.
