My 91 tin top had just about all the parts of the AC system renewed. No leaks anywhere but continued to lose freon. On the recommendation of a friend from Canada I refilled with Duracool. Bigger molecules. Still cool every day here in SW Florida.

It had it converted to R134a two springs ago. It got all new fittings, the system was flushed, and new proper lubricant for R134 was added. It cooled wonderfully well, but by summer's end it was not doing so, despite two shops claiming not to be able to determine that it was leaking. They reported that with a "leak down test" over 24 hours, it held proper pressure. > > So, next spring it needed recharging again, and again, "leak down test reveals no leak." By summer's end, it was not cooling. Recharging resulted in the thing cooling marvelously, air temperature from the plenum being around 48 F. So, what do I do now? I plan to use the camper this spring, summer, fall and will need air conditioning for some trips through the plains and Southwest. > > Help! > > David McNeely
