The ac just was not cooling. DH put freon in it and it still would not cool. The he thought it was the compressor. He decided to get a new thing that you use to add the freon. That worked well, and he got the freon with stop leak in it. Fingers crossed that its stays cool, I advised him to keep some with the applicator in his truck tool box. Would hate to get out on the road to Illinois in the heat of summer and the AC go out.

MHO...As a rule of thumb, nowdays and with the new mixed or basterdized refrigerants its best to just dump the charge if any is still left in a system that leaks. Then charge slowly with nitrogen but to only check for leaks not to exceed 300psi. Fix leaks. Then vacuum pump it down before adding refrigerant what the manufacturer says it takes.

If a lot of oil is lost from a leak, or while fixing a leak, you may need to add some.

Add.. I've only have little experience with auto/tractor AC, and r134a.

Maybe worked on only a few dozen rigs, so hopefully someone with more experience will add better advise.

For A/C, you really need to find someone professional that has an excellent rep, and a decent warranty. Because, if something goes wrong with your A/C, it can put both your vehicle and you in jeopardy, i.e. compressor failure locking the engine, stranding you somewhere unsafe. I'm an auto mech/tech, but without owning the proper equipment to do A/C work, I allow a shop to do it.

Make sure you let any shop know you put stop leak in it. That will ruin your ac system AND the service equipment hooked up to it.
Sorry, but that was a very bad move.
Instead of repairing the systen, now the evaporator, compressor, orfice tube, condensor and drier will need to be replaced. Stop leak turns into a concrete-like mess.
