The lowest-priced 1.5 ton inverter split here, rated to 54°C
Our editorial score
Good — right for the specific buyer
Budget buyers with a middle-floor room of up to about 180 sq ft
At ₹37,690 at Reliance Digital, this is the cheapest 1.5 ton-class inverter split on our list, and it keeps the essentials: a 54°C tropical rating, iceClean, inner-grooved copper tubes, stabiliser-free operation and 10 years on the compressor.
Its rated capacity is 4,800 W, about 9% under a true 1.5 ton, and its ISEER of 4.3 is modest. It is a strong AC for a middle-floor room of up to about 180 sq ft, or around 130 sq ft on a sunny top floor. The image is an illustration, because Hitachi does not publish model-coded photos.
Every condition below is derived from this product's published specifications and from how it compares with the air conditioners we track — so you can check each one against your own room, supply or budget rather than take our word for it.
You live outside a metro or a major service town
Hitachi's service network is rated limited rather than excellent. Filter availability and callout times are what decide whether a purifier is still running in five years, and they are worth checking for your pin code before you buy.
How we score service reach →Length of cover matters to you
Total cover is 12 months, against a median of 60 months across the ac purifiers we track.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
A premium Japanese engineering brand with a deliberately small Indian range concentrated on large-capacity French door and multi-door units. Hitachi's vacuum-insulated panels give more internal volume per external millimetre than almost anything else, and its Dual Fan Cooling is among the best implementations of separated fridge/freezer airflow. Expensive, narrow, and excellent if the model you want exists.
