Aoa,
I got khyber 93. got installed senden AC 5 yr ago and got serviced in 2012.
Since begining it is giving us trouble except for first year, when its cooling was better than new cultus cooling.
Problem is this we need to charge gas every year befor we got serviced in 2012.
previously it s R12 gas. cooling ws good in evening but not good when it is very hot esp in june-aug.
this time mech change oil and gas to R134, cooling good at evening, but not good in the day, once when we got it re checked, he put some water on radiator, got little gas charge and said, it is ok, for few days, it was good, again, same problem. aik or mech se bi baat ki thi, muger, mujay to ye sab chakri lagtay hain.
kya kia jai. me in islamabad
