Ok, so long story short, my AC condenser needed to be replaced 2 weeks ago and the only place in town that had one for less than 350 dollars was a salvage yard. So I bought it, hooked it up and recharged the AC. But now my ac isn't blowing cold, a friend of mine said I might need to take it to be vacumed... I don't really know too much about any of this. Could it need to be vacumed? Or could it be something else? Thanks for your input.
