Two weeks ago I had my aircon re-gassed at a local garage as it wasn't cooling at all. For a few days after it was great, really cold. Then I noticed a bit of a whining noise that seemed to occur when the aircon was on and the engine was idling.

Now I'm not getting any noise and the aircon is no longer cooling at all. In fact, when turning on/off the aircon I'm not even noticing a change in air flow like I did before.

Any idea what could have occurred here? Before going back to the garage I'm trying to get an idea for if it could have been just caused by the re-gas? Could they have done something wrong? Or just a coincidence?
