Have to recharge AC more often than filling up!
I recently treofitted the AC system in my 88 Camry to R134a. It ran fine for a while but I've noticed the 'coldness' of the air slowly disappears after a few days (week) of recharging with the freon. I almost have to recharge it everyweek to keep it cool. How often does a recharge last if the AC is used normally (30 min of day driving in my case)?
May be I am not recharging it to the full capacity - It always strikes me that 'too much is not always good'. I normally do look for the gage to point to the maximum of the blue area (I forget the scales but it I think it goes like this: green, blue, yellow and red).
Any suggestions as to what I can do to recharge the AC less often than I visit the gas station? Thanks in advance.
