Ac problem

What would cause my ac to keep fluctuating between blowing cold them blowing warm?

I just double checked the system again and it seems that it must have gotten overcharged. Damn, it read completely fine when I charged it and now it's overfilled.

That's true Greggyg If you're not educated in refrigeration/air cond. best to leave to experts and sad to many so-called garage experts don't know either. If that's the case best to feel the return tubing a few inches from compressor and when it starts getting really cold it's time to stop filling. That assures that the evaporator is full of expanding refrigerant/oil and making its way to the compressor to keep it cool and lubricated.
Do this at your own risk as there are dangers around the fan, belts, etc.
