I just had my ac compressor replaced and refilled and it cost me $420.00 including labor and refill, plus a warranty on a new compressor. Not sure how much different it would be on an aurora but I would just call around to at least three different shops in your area that do this type of work and ask for a quote for replacing the AC compressor and refilling it. Get an installed price quote.........compare the prices and see who is ripping you off, if anyone.
