How do I choose the right AC for my room?

Start with tonnage — it's the one decision that matters most, and it comes down to your room size and your city's climate (the calculator below gives you an answer in seconds). Once you know your tonnage, pick the highest star rating you can afford within it, since that's what actually saves you money every month for years. WiFi, air purification, Hot & Cold — those come last. They're about convenience, not cooling, so choose those based on what you personally want.

Getting tonnage right matters more than any single feature — an undersized AC never cools properly and runs constantly; an oversized one cools too fast without properly removing humidity, and costs more upfront for no real benefit. Once tonnage is set, ISEER (star rating) determines your running cost, and remaining choices (WiFi, air quality, Hot & Cold) are about convenience, not cooling performance.
