Just had my aircon repaired last friday, breakdown of expenses incurred are as follows:

Fuse holder with fuse - - - - - - ----------------------------------- P 170.00
Auto relay - original 280.00
thermostat 480.00
shaft seal 950.00
machine shop (pully and plate) 350.00
overhauling oil 200.00
charging valve - 134a 190.00
aluminum welding 150.00
Small O-ring gasket 84.00
Vacuum actuator 1,100.00
General cleaning with full freon charge 1,800.00
Fuse holder with fuse 170.00
Auto relay 280.00
----------
Total 5,750.00

Now may aircon works fine (even the idling has been restored), power steering is lighter (di na mabigat tulad ng dati). Will observe pa, meron namang 3 months warranty ang shop. The shop by the way is R & L Aircon here in Iloilo City.

Pricey ng kaunti pero meron namang peace of mind IMO.
