2005 Ford f150 5.4 Triton

(2005 Ford F-150)
My AC freon seams to be leaking right away and I can't find the leak. I took it to precision auto & they said they couldn't find the leak. They said the hoses are good and the ac compressor is good. They just said they didn't know why it was leaking.
What seems to make the problem better or worse? Its leaking out and idk why
How long have you had this problem? Not sure I bought the truck like this

Usually a uv sensitive dye can be added to the system then after operating for awhile testing with a uv light should show the leak source - the uv dye will fluoresce under the light.

Otherwise it is very difficult to pinpoint the leak.

IF the leak is in the evaporator - the water droplets will contain this uv dye!

I must assume (hopefully) this testing has already been applied (?) However it may not have been performed diligently enough..

Good luck!
