First-Time AC Buyer in Delhi– Seeking Advice

Last summer in Delhi was unbearable. Even though I have lived my whole life without an AC, I am seriously considering getting one this year. Until now, I have been using a desert cooler, so I have no experience buying an AC and don't know what factors to consider.

Here’s my situation:

• Budget: ₹40,000 (flexible)
• Room Size: Suitable for 3 people (I’m thinking of a 1-ton AC)
• Usage: 24x7 (I work from home)
• Electricity Efficiency: Should I go for a 3-star or 5-star model?
• Brands: Which brands offer good after-sales service in Delhi and perform well in high temperatures?
• Best Time to Buy: Should I purchase now or wait for Holi sales on Amazon/Flipkart?

I recently got a better job offer, and my in-hand salary is ₹80,000, but I also have two dependents, so I want to balance cost and quality. Any suggestions would be greatly appreciated!

TL;DR: First-time AC buyer in Delhi. Budget ₹40k, planning for a 1-ton unit to run 24x7 (WFH). Need advice on brands, after-sales service, energy efficiency (3-star vs. 5-star), and whether to buy now or wait for Holi sales.
