I just repair my aircon because of air con not cold, top up gas but still leak.
Work involve -
1. Trouble shoot cooling coil, strip and test / check for leak.
2. Trouble shoot compressor for leak.
3. Check all other joints / hose / adaptor fittings for leak.
4. Check condenser for leakages, need to strip radiator. Basically, he check the whole aircon system.
5. Change1x external aircon dryer ( bullet shape part). This part expensive ???
6. Change 1x aircon hose.
7. Changes 1x switch ( leaking ) at external aircon dryer.
8. Changes about 5 new o rings.
9. Service - wash and clean all pipings, and chemical wash condenser.
10. Top up new air con gas and oil.
All in the above job took more than half a day with one air con expert mechanic full time to do my car.
Much of the time was spent trouble shooting ( stripping out the parts )for the leak and HE CHECK AND TROUBLE shoot each and every component instead of asking to change all.
Din ask for breakdown but all in Damages RM 494.....aircon repair expensive.
