For this usage, the higher star pays back in about 3.3 years — worth it over the AC’s ~10-year life.

A planning estimate. ISEER values per star are indicative — BEE revises the star tables periodically, so check each model’s actual ISEER on its label. Real savings vary with usage, weather and tariff slab. Compare ISEER numbers, not just stars, and remember the star is only part of it — right-sizing and how you set the AC matter too.
