How much does it cost to re-charge the AC system, and where is the best place to go please?
Please describe what is wrong with it.
Was the system completely empty?
Was the system left empty or open to atmosphere for any amount of time?

It's because we don't have any specifics on what is wrong with the system.
Has the system lost all of its charge?
Is it just low on charge?
Is it even a charge problem or maybe a pressure switch or compressor clutch issue?
Was the system open to atmosphere which can introduce moisture to the system?

If the system rapidly lost its charge it will likely do the same again since there is a leak therefore the leak should be found and repaired before charging the system.

If the system was completely empty then there is air in the system and the system needs to be vacuumed first.
At this point if there is a leak it will still need to be fixed before proceeding.

If the system was left open such as would be the case of a broken a/c hose and it was driven in the rain then the compressor oil would need to be drained and replaced and the suction accumulator which also acts as a dryer would also need to be replaced before the system is tripple vacuumed and charged.

If it is simply a little bit low on charge then you can use the DIY kit

why do you say this? I have a leak also in my a/c lines that I'm gonna replace. I need to know if I can just get a couple of cans of A/C to recharge it or do I have to take it somewhere?
Once the system is open to atmosphere the air needs to be evacuated before you recharge it.

If you are going to replace the line then do it right before bringing it to have it vacuumed and charged.

Did this line completely empty the system?
Is the line broken off which would allow water to get in?
If water has gotten in then you have your work cutout for you.

after my build last summer the lines began to freeze and the AC was weak. Now I have no AC what so ever.

It seems it's common on the 05.
Mine is blowing hot air since two years. One day i will take care of it. Either remove or either fix.
Even brand new i always thank it was not cold;

if you need a recharge you have a leak. Get it repaired first before you spend the $ to recharge. Its only gonna leak out again. AC should never have to be recharged during its life.. Refrigerant does not get used up.

Yes the lines where emptied. I had to disconnect the lines that connect to the condensor.

The line that has a leak shouldn't allow water because it was just the hosing that broke the air tight seal.

Then have it vacuumed and charged and you'll be good to go.
Air that is in the system is non condensable so it will cause all sorts of problems such as high head pressures, less than optimum cooling, compressor failures due to the high pressures etc.

You should really pull a vacuum on it and put in the right amount of R-134.

Pull a vacuum for atleast 30 minutes and then close the valves to see if the system holds a vacuum, if it doesn't then it's time to try to find a leak. If the gauges don't move then charge the system by weight.

Not too many people have a 2 stage vacuum pump available to them.
If they do they should then pull down to 400 microns and shut the valves off.
If it rised to above 2000 microns then they have a leak.
