always find a second shop, for a second opinion.
weak A/C
is the air flow from the blower good, nice and strong.?
i believe this is r134 freon. get the freon kit and read the instructions, on the label. (papers)
try this, kit the fitting only fits one of the 2, Freon fittings.
if it keeps losing freon, there is leak there is dye you can use to find that too.

the charge dial shows 25 to 55 for green, good. that number is PSI, pounds per square inch. its a pressure gauge.
mine liked 40. FIY. (was humid here)
if you overcharge it, the cooling drops.
make sure the dampers are working right and air does flow through the A/c EVAP CORE, freely, no leaves or other dirt in there blocking the air flow.
im sure he checked that first. but.....
and of course the 1st check is not freon, its.
1: air blockage to the evap core.
2: then make sure the compressor shaft spins fast. (no belt slip) the pulley spins full time but not the compressor shaft.
3: if the compressor, shaft cuts out,stops spinning , we need to do more checks at the A/C amp (logic box) for why? ASK.
see the core>? here, it must flow air.

here is the pressure chart in the manual.

what is the outdoor temp
and humidity.
say its 80F and 50% humidity
the low side pressure would be 43 psi at 2000 RPM (engine RPM)
it might be a 10cent fix, a simple wire loose. that cuts out the compressor.
always watch it.
the center of the pulley in electric clutch, (on or off) if the compr. shaft stalls, the clutch is cutting out. (ask for more tests)
