Would the evac for an hour or longer actually remove any moister or should i just go ahead and replace all o-rings, dryer, orifices, evac and fill? I think my cost would still be manageable if i dont screw anything up????
The evacuation will remove moister because the vacuum in the system would cause water to vaporize and then it would be sucked out. Basically when a high vacuum is created and is sustained it causes water to boil.

As for the drier it is generally wise to replace the drier however you don't have to everytime you do a repair. Generally every 6 years is best, by that time refrigerant has hit 50% of it's half life.

The o ring I recommend you replace them because chances are then never have been replaced but you might not have to because if the only leak is coming from that valve then you're fine and as long as you don't disturb anything else then it would be fine but once you loosen something with an old o-ring then that o-ring will need to be replaced.

Trust me it works out to be cheaper, I called around and visited some people I did work for and the prices were around 170 bucks, it cost me only 100 bucks in refrigerant and tools to do the job. I got the manifold for 40 bucks and the refrigerant cost me 50 bucks. big lots...

But best of all if you ever have to service your a/c system then it would only cost you refrigerant and o-rings as general service.

The vacuum pump cost me 100 bucks from harbor freight but I returned the pump the next day.

Trust me you will not screw up anything, it's a very easy thing. People try to make it seem hard but once you do it you will be like, what the hect are people talking about hard...
