Thanks Alot for such a detailed reply Sir.After having experience with various brands personally, including Super Asia, Dawlance, Panasonic, Mistsubishi (slim & heavy), Hiar (if thats how its spelled), Pel & Orient, i can confidently tell you that currently The Best AC going on in the market is Orient. Locally manufactured, is of decent quality but the Performance is Top Notch. With proper maintenance, it'll easily last you 6-7 years. (But please make sure you don't let any local mechanic touch it. ALWAYS call the company person to get it fitted and even if you have refill gas, call the company man. May cost more but is more reliable)
7 Years back my we purchased a Super Asia 1.5 Tons AC and it was the best thing we have ever purchased. Was OK on power consumption but the performance (and throw) was So powerful that It'd cool my Hall Like Room in less than 10 minutes, and after 30 minutes ... it'll be impossible for you to sit infront of it because it'll start to freeze you. (In an accident, its out door unit got busted about 3 years ago - A Shotgun shells shredded the compressor ... gun fight right outside my door between two gangs was the reason)
I'll spare the details but we currently are running a 1.5 tons Mistubishi Heavy (don't remember the exact model atm). It costed us approx 70k+ (after installation - the cost o AC was 65k something) last season and let me just say ... having good experience in past with Mistubishi, i can confidently tell you that its NO USE spending huge amount on this. Just DONT. Its wasteful. The performance is Awful. Throw is fine though.
So called "Imported Compressor" is just a hoax. Everything is locally manufactured and their sell you "slightly better quality one" for more price premium than locally manufactured.
Orient at about HALF the price of Mitsubishi (either Slim or Heavy) can perform X2 better. You can visit any family person or a friend who have one installed.
So my suggestion would be to go for a 1.5 Tons Orient AC.
It was really helpful. I have definitely added Orient to my shortlist.
