BEWARE! Greulich's is one of those shops that gives mechanics a bad name. This place will try to sell you more than what you need just to get more money out of you. I came in because the A/C wasn't working in my car. After looking at it, I was told I needed a new condenser and compressor in addition to the new Freon (which I expected to need Freon). All in... $1,700.
I decided to get a "second opinion" and went to a nearby shop. It turns out that I just needed new Freon which was $600.
One last thing to note, I found out that Greulich's damaged one of the testing ports for my A/C system which I needed to have replaced. All in all, horrible experience and I'll never come back.
