Click To Read Reviews


Build Aspect

IA512ILU is the new-gen 1 Ton Split Air Conditioner from Blue Star. The design is unlike the boxy shapes usually found on Blue Star ACs. It has a well rounded and curved shape with a rich gloss white facade. A neatly hidden display together with a well proportioned layout make it quite pleasing. Surprisingly the ODU while is well made lacks in heft, which raises a few eyebrows.

Performance Aspect

This AC has a very good compressor which can cool a small, small-mid sized room quickly and effectively. The 13648 BTUs promise to give the occupants a healthy dose of cooling, when the mercury soars. This is achieved in a very efficient way, with an ISEER of 4,65. Thankfully with a design change the fan motor seems a change too, it now pushes 365 CFM of air which is much more passable than the lethargic 309 CFM of the EBTU model. On the flip-side this AC has only 2 way auto swing. Unfortunately noise levels take a hit with increased fan speeds. Taking into account the potent compressor, good build quality it can be inferred as one of the best 1 ton split AC in India.

Also: Do view this fantastic 5 star 1 Ton Split on Amazon before finalizing.
