Hi, my fren's car a/c blowing hot air recently, put in new gas but only lasted a day, diagnose by a/c expert .....cooling coil leaking. The coil was finally replaced(new) and a/c is blowing cool again... at a cost of $2600! this is d 2nd coil change in 2 years, previous one is also new & oem.Just for discussion, has anyone use cheaper china make coil? how long does it last? or is there any reasonable price longer lasting coil in the market? check online and found plenty very much cheaper coil!
 
I don't think cooling coil cost that much (RM2,600). Think should be around RM 1.3k from Naidu under the tree. Many have changed their cooling coils from Naidu and could easily last 5 years.
 
i got one spare... very good condition selling RM500. call me interested 012-2553340
 
forgot to add, $2600 is for ori coil + workmanship+ gas, the coil that u guys changed, is it ori? or which brand is good?
 
I changed mine cooling coil with naidu on 10.7.2010. He recommended the copper instead of the aluminium coil. He claimed that the aluminium coil leaks often whereas so far he has not had any of his customers returning for warranty claim for the copper coils. The copper coils is cheaper around RM590.00. So far so good!
 
Sounds like there's a cheaper alternative...but copper do oxidize no? There's so much vapor at the cooling coil. Unless its already treated or its mixed with some other alloys...

I would have thought copper coils should be more expensive than aluminium coils. Though copper should be more durable as compared to aluminium, I believe the cooling effect of aluminium is much better. Correct me if I am wrong.
 
Herbert,

Yes according to Naidu, the aluminium coil would cool faster compared to copper..but as for my e39., there is no difference between the two. My aircond before and after the replacement freesez hell even at 25 degrees...
 
cooper coil

Yes, my mechanic Fren did mentioned that cooper coil last longer, my e34 cooling never bocor. I thought cooper coil is.more expensive, $590 is cheap, got it at naidu?, how much did he charge for installation?
 
Yes got it from naidu. Labour charges is RM450.00 include removing the whole dashboard and servcing the aircond..

I am of the same opinion also. Copper price now is at least twice that of aluminium (i am comparing raw materials, as my factory's copper electric cable cost twice that of aluminium cables, but much better capacity and conductivity)

all household aircon are using copper coil. if alumiunium is better, logically all should use aluminium which is much cheaper.
 
i got original cooling coil 95% new.... interested PM me your best price..

This is because copper is harder and aluminium softer. If the aircond in the house using aluminium for piping...........i think not long period later u will heard .........zzzzzzzzzhhhhhhh
 
Aluminum is generally a more difficult metal to work with compared to copper and hence the more expensive price although world market price may suggest otherwise. Being more galvanic compared to steel or copper which could exist in the ac system makes the aluminum corrode faster which makes it give away faster. Aluminum performance could be better though but the size of the system makes a small difference only.
My 2 cents worth.
