I went to Ahmad Car AC in Lahore yesterday; they are pretty famous here. They guy there said that sanden AC gonna cost 32k while denso gonna cost 45k. I asked him if he will work with jdm compressor if i provide him one. He said he wont. Though Ahmad Car AC is excellent and honest but he will not work with jdm compressor.
Yesterday i saw a brand new mehran getting fitted with new ac with jdm compressor, i checked it and took a try and ac was working ridiculously good. also its blower was like cultus; i guess euro 2 has different and stronger blower. Also there was negligible load on engine due to that compressor. i exactly remember i couldnot drive my car on cng with ac when i first installed ac in my mehran.
euro 2 ac is a bit different, i saw wires attached to receiver dryer though i dont know what they are for.
almost all mechanics said mehran fan is good enough for cooling. no body recommended me to change it. though experts at pakwheels suggest various tweaks to boost up performance including replacing fan with a stronger one.
the cost of brand new ac with jdm compressor is 22k (i took estimate from 3 shops at different locations.)
