Our verdict
The IC524DNUR is the best-value 5-star 2 ton on our list: ₹54,990 on Blue Star's store, an ISEER of 5.05, 936 declared units a year, a 54°C rating, five convertible steps, 4-way swing and 10 and 5 years of compressor and PCB warranty.
Its 6,100 W rated cooling is below a true 2 ton's 7,030 W, so it suits a room of up to about 230 sq ft rather than a 280 sq ft hall. Wi-Fi is an optional ₹1,699 kit rather than built in.
What we like
- 936 declared units a year — about ₹7,488 over a BEE season at ₹8 a unit
- Rated to keep cooling at 54°C outdoors — real headroom for a top floor in a 45°C city
- 10-year compressor warranty and 5-year PCB warranty
- 5-in-1 convertible — runs as a smaller AC on mild nights and draws less power
- One of the lowest prices on our list for a 2 ton 5-star split AC
What we don't
- 6,100 W rated cooling is 13% below a true 2 ton (7,034 W), so size it for a smaller room
- Wi-Fi is not built in: smart-ready — wi-fi kit costs ₹1,699 extra
- Carries a 2025 BEE label — BEE tightens star bands periodically, so compare it with 2026-label units by ISEER rather than stars
When this is not a good choice
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.
Low running cost is a priority
Consumables and routine service run about ₹7,488 a year, which is in the most expensive quarter of the ac purifiers we track. Over five years that puts total ownership near ₹92,430.

About Blue Star
India's strongest commercial-refrigeration engineering house, now selling domestic refrigerators too. The commercial heritage is the point: Blue Star's deep freezers, visi-coolers and glass-door merchandisers are the default choice for Indian shops and restaurants, and the domestic range inherits that build discipline. For a shop, a clinic or a restaurant, this is usually the first brand to call.

Blue Star 2 Ton 5 Star Inverter Split AC IC524DNUR — frequently asked questions
What room size is the Blue Star IC524DNUR suitable for?
Rated at 6,100 W, it suits a middle-floor room of up to about 230 sq ft with a 10 ft ceiling, or about 170 sq ft on a top floor with strong afternoon sun. Each person beyond two adds load, and a room open to a kitchen needs more. Our AC tonnage calculator works this out for your exact room.
How much electricity does the Blue Star IC524DNUR use?
Its BEE label declares 936 units a year, measured over a 1,600-hour cooling season — about 5 hours a day for 11 months, or 8 hours a night for 6-7 months. At ₹8 a unit that is roughly ₹7,488 a year, at an ISEER of 5.05. Real use varies with room size, set temperature and how hot your summer is; setting 24-26°C rather than 18°C cuts it substantially.
What warranty does the Blue Star IC524DNUR come with?
10 years on the compressor and 5 years on the PCB, as listed by Blue Star. Warranty on an inverter AC matters most for the compressor and the PCB, the two most expensive parts to replace, so check both are listed on your invoice and register the product with Blue Star after installation.
Where can I buy the Blue Star IC524DNUR at the best price?
We list ₹54,990 from Blue Star official store on 2026-09-14. AC prices move weekly and are often lower on Amazon and Flipkart, especially in bank-offer weeks, so compare all three before buying — and check what installation is included, because extra copper pipe and an outdoor stand are usually charged separately.
