A/C not cooling properly

My A/C unit had stopped blowing cold air. Took it to three different shops. All told me that the freon had leaked out and there was no way to refill even if they were able to fix the leak. There are no ports on the majority of RV A/C units in order to recharge. Is this true?

Yes they are a sealed unit. Some technicians will add a high/low port to recharge but you still need to repair the leak. And you are still running an old unit prone to leaking again. Generally by the time you do all this you are close on $$$ to just replacing the unit that will include full warranty etc.
