What's the best 5 star ac to buy in India?
The Carrier 1.5 Ton 5 Star Flexicool inverter split AC is our top pick because its listing states an ISEER of 5.6, annual energy consumption of 663.31 units, cooling at 52 degree Celsius ambient, a 100% copper condenser coil and a 1 year standard, 5 years PCB and 10 years compressor warranty. Optimist's 1.39 T WiFi model lists an ISEER of 6.05, 620.2 units a year and a 5-year warranty on critical functional components.
On its BEE label (2025 ratings), a 1.5-ton 5-star split AC uses roughly 685–780 units of electricity a year versus about 900–1,000 for a 3-star (at BEE’s standard 1,600 running hours) — the higher rating saves about ₹1,600–2,300 a year at ₹8 per unit.
