exactly...i changed 3 cooling coils within 6 mths...all recond, no choice cos brand new not available.Normally if you go service your air-cond. unscrupulous poreman will spray strong alkeline on your cooling coil for cleaning purposes.
But this process will also cause the thin manbrane to kena hakis and leak. End up need to change cooling coil.
Means old school also......When?
When the aircond is no longer cold.. ahhahaha
Probably nothing wrong then. Maybe just wind the windows down for a while to let the hot air out....for faster cooling.....Mine still cold but takes more time to cool the cabin up. Especially if parked under hot sun. Wanted to service but got distracted by so many other things i.e. change suspension, disc brakes conversion etc..
