Our verdict
Most AC spec sheets say a unit will run at a high ambient temperature. Daikin says something more useful for this model: it delivers 100% of its rated cooling at 46°C outdoors and keeps cooling up to 55°C. That is the specification that matters on a top floor in May, and it comes with an ISEER of 5.70 and 679 declared units a year on the 2026-27 label — about 200 fewer than Daikin's own 3-star 1.5 ton.
At ₹55,990 at Reliance Digital it is one of the pricier 1.5 ton units here, Daikin's sheet puts its capacity at 1.42 TR (5,000 W), and the product page did not show warranty terms when we checked. If your AC room is on a middle floor, the ₹15,000 extra over the ATKL50XV buys efficiency you will recover only slowly.

What we don't
- Warranty terms were not shown on the product page — confirm compressor and PCB cover before paying
- 5,000 W rated cooling is 5% below a true 1.5 ton (5,276 W), so size it for a smaller room
- Compressor and PCB warranty terms are not stated in text on the product page — confirm before buying

Daikin 1.5 Ton 5 Star Inverter Split AC ATKM50XV — frequently asked questions
What room size is the Daikin ATKM50XV suitable for?
Rated at 5,000 W, it suits a middle-floor room of up to about 190 sq ft with a 10 ft ceiling, or about 140 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 Daikin ATKM50XV use?
Its BEE label declares 679 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 ₹5,432 a year, at an ISEER of 5.7. 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 Daikin ATKM50XV come with?
Warranty terms were not shown on Daikin's product page when we checked. 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 Daikin after installation.
Where can I buy the Daikin ATKM50XV at the best price?
We list ₹55,990 from Reliance Digital 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.
