a/c small leak

FranktheTank · Apr 17, 2012

So I know I have to have a small a/c leak somewhere... I took it in the my mechanic (I trust him) and he put evacuated the system and put fre-on in and the dye. after about 3 hours later he called me and told me that he couldn't find any dye anywhere and that it was still holding a good charge. So can the leak be that small? or idk what to think?

I had a similar issue a while back. Couldn't find the leak. It turned out to be leaking at the A/C valves. Remove the caps and add a couple of drops of water and see if it bubbles, you never know.

If you haven't been playing with the A/C system components then generally the schrader valves are the number one culprit in A/C refrigerant leaks. Is that the first time that you had to add refrigerant or has this been a reoccurring problem? I assume your mechanic check everything from the refrigerant lines, filter dryer, compressor, coil, & condenser?

yes it has been a reoccurring problem, probably for about a year and a half now, I would just buy some freon fill it up, usually about one of those big bottles and it would last like 2 months. I haven't fixed it yet, because usually I can take the cali heat but now with a baby on the way I have to get it fixed.
