Window AC vs Split AC Electricity Cost in India (2026):
Real Cost Comparison India
Window ACs were India's dominant AC type until the 2000s. Today, split ACs have largely replaced them due to better efficiency, lower noise, and better aesthetics. However, window ACs still make sense for small budgets, rental properties, or rooms where outdoor unit placement is impossible.
