At first estimate (before actually breaking into the a/c compressor, etc., Ari and the guys thought it looked like a complete re-do of a/c. In other words, around a grand for parts/labor. I trust them so much that I gave the go-ahead. Once they opened it up it was found that just some key parts were needed, but not the entire compressor (I don't know enough to even give much detail). The price was a little over half the estimated amount. Sci-Tech could have stuck it to me, but that's not who they are. They are not only reliable and competent, they are ethical! Wow. What a breath of fresh air to have this type of automotive repair shop.
