I took my Tesla Model 3 to Green's Garage in March to have the air conditioning repaired. They quoted me $450 plus tax to assess the a/c, part of which would be credited toward the repair. The next day when I picked up the car I was told they could not find anything wrong with the a/c. I was told I was welcome to return the car at no charge for further review. On the way home, I could tell the a/c was still not working. I decided to book an appointment with Tesla and not waste more time. Tesla replaced the HVAC, Evaporator Thermistor for a total cost of $88.90. They a/c is working fine now. I called Green's Service Manager and told her about my experience there and the subsequent repair by Tesla. She said she would speak to her manager. I haven't heard from anyone. Total cost at Green's was $497.25 for a poor diagnosis. If you have a Tesla, skip Green's and just go to Tesla. (Green's also quoted me on replacing my door handle, their parts only price was equal to Tesla's labor and installation price.)
