Click To Read Reviews


Build Aspect

3W18LD is a 1.5 Ton window AC from the cooling giant Blue Star. The first impression of the AC is that of a simple and industrial unit and that in fact stems from the straight and clean lines on its front, nevertheless it shall not ruin any interiors. Over and above that it weighs plentiful too and it screams durability and quality all around. Even the remote is well made has a perfect lay out making it easy to use, not to forget it is backlit too.

Performance Aspect

The core aspect, the cooling performance of this Air Conditioner is very good. A superb 17162 BTU capable compressor makes sure that the occupants are relived from hot and humid temperature in a very quick time. This is further aided by a pretty powerful fan, which is able to churn out 449 CFM of air. But then the noise levels of the AC are a bit high, partly because of compressor noise, partly because of fan speed. Add to it the fact the energy efficiency is rather poor too with an ISEER of 2.91 only. Having said that the price is very attractive and all in all given its above par and good cooling performance this AC is a good and one of the best 1.5 Ton window AC in India.

Also: Before deciding do view this Top Rated AC on Amazon.


Robust build quality.
Good cooling capacity.
Very good air flow, almost 450 CFM.
Intuitive layout of remote.


Somewhat high noise levels.
No PM 2.5 filter.
Disappointing ISEER, just 2.91.
