Looking for advice on a good 1–1.2 ton Air Conditioner

I’m planning to buy a 1 or 1.2 ton AC and want to make a smart choice. I’m focusing on overall cost, cooling performance, energy efficiency, and service availability in India.

Which brands/models do you think are the best considering value for money, long term performance, and good service network?

Also should I wait a few weeks for upcoming offers/seasonal discounts or is it a good time to buy now?

Any recommendation based on your experience would be much appreciated.
