A/C R134 retrofit from prev. R12 = poor performance..any ideas?

[TM]

Chris,
Did your mechanic do it the right way?

Right meaning- replace all seals and hoses, replace the
receiver/dryer, evacuate the compressor and the rest of
the system for at least 4 hrs. before recharging, verify
all replacement hoses are of the nylon barrier type, check
for leaks in the system w/ UV dye.

My 5ktq after retrofit blew very cold air, had some problems
w/ leaks that took some resolution, that was the biggest problem.

i had R12 in my a/c system up until a few weeks ago, then it stopped
blowing cold. so i was advised to retrofit my '86 5kT to R134. Now, with
the R134 retrofit, the performance sucks.  its not even enough to cool
the car.  with
the R12 it was nice and cold, now it's not.     mechanic says that's all
i
can expect from a retrofit.  is this true??
 any ideas?
TIA
