Dr. sb. good to see you here too 
Well as I mentioned there are few tricks & jugaars.
Actually when I went to AC shop to fix its cooling system, the Toyota’s original compressor (Kabuli or repaired one from bilal ganj, who knows) price was ~30K. After charging gas, and other things (o-rings, valves, coolant, etc.) the total kharcha was going over 50K.
While at that time Honda BRV’s compressor was for 16K only. But apart from the price gap, I trusted the person because I know him over many years and he gave me guarantee that if it doesn’t work, then i can shift back to Toyota’s compressor and he will not charge any labour for doing all the job again.
However I must accept that Honda BRV’s compressor in 2006 Corolla worked best for me & economical too.
