Was my first time working on my mini and as i was changing my alternator i loosened the ac line in front of it i ended up hitting it and just fully discharged it. A/C still comes on and the compressor works but just blow warm air now.
Would a can of 134a be worth trying or is it better to just have a shop look at it now?

 

Hello,

If you secured the ac line, Imho - its worth attemping to re-charge ac yourself.

good luck

 

You'll need to secure the a/c line and vacuum out the lines before recharging the system. I do my own a/c work and it's not too difficult.

 

uh a little more than you describe....
from a similar thread...

The proper way is to use the following: a set of gauges and a tank of R134, a vacuum pump and a mail scale.
First hook up the gauges to your cars high and low side valves. Hook the gauges to the vacuum pump. Turn on the pump and open both gauge valves. Vacuum the system for 1/2 hour. Shut off pump and shut the gauge valves. Leave the system hooked up for half hour. Watch and see if the system stays vacuum. Hook the gauges up to the freon tank and put the tank on the scale. Zero the scale. Open the high side valve and allow the amount of freon needed to enter the system. Shut off the freon tank and start your car. You should have cold air.

 

My A/C guy charged me $80 to do it... seemed fair.
