Window AC vs Split AC:
Which Is Right for You?
The most common AC buying dilemma in India — answered with data. We compare both types across 10 real-world factors so you can make the right call for your home and budget.
Window AC

Frequently Asked Questions
Common questions about window vs split AC in India.
No. Window ACs are only available up to 3-star rating, while split ACs go up to 5-star with inverter technology. A 5-star split AC consumes 30–40% less electricity than a 3-star window AC of the same tonnage. The higher purchase price of a split AC pays back in electricity savings within 2–3 years.
