Hello cheelam,

I recently went and service my air cond because it wasn't cold. It was cold during the early mornings and late evenings, but hot during the afternoon (just fan, no air cond).

So i had it service because i think it's been a long time since my last service. The air cond guy told me that i have to clean the air filter (i think) and pump gas, and also there was some leakage at the cooling coil, and in order to save money for me (because i was doing other repairs to other parts too), he suggested to do 'welding'.

When i got back the car, it was night time hence the air cond was working. but after that, it was still hot, although cooler than before. About a month later, i sent the car back to the same workshop.

This time, another air cond guy (same workshop) came and said if cooling coil got problem, he will actually suggest to CHANGE the whole thing, instead of welding. Coz he checked the air cond gas and it was running low. He said there's only two problems. 1. The guy before didnt pump enough gas. 2. the cooling coil have to change.

This guy pump the air cond gas for me and the air cond was cold again. However, as I was driving home (25km) during the jam, I realize the car temperature is higher than normal, although still within the safe range. but it was never this high before. Can it be the cooling coil problem? Can this affect the car temperature?

My radiator is fine, i just cleaned/service the radiator, and seems like my compressor is working fine too.

I'm driving a old Toyota Camry, 1994 version. How much is it to change the cooling coil at your workshop?

Thanks
