I'd like to know if I need a new ac unit. My AC stopped working so I took it to Midas, the fixed it for a day then it stopped working again. Took it back an dthe said the piched an O-ring. They fixed that and it worked ok for about a week then it stopped working again. If I need a whole new unit How long would it take and approximately how much will the cost be?
Any help would be greatly appreciated.

Hi Kelsie,
Thank you for the donation. Don't think of an A/C unit in a car like one that goes in the window. It is spread out and components are tied together with hoses and lines. You fix what is wrong and cross your fingers.

When an a/c system leaks freon, the gas sometimes has dye in it. The dye leaves a mark to show a leak. After the repair is made, the system can be checked before filling the sytem back up. A vacuum is put on the system and is monitored for any air coming in. IF good you fill it. Since the system hasn't been under pressure, problems can happen. Seals shrink, moisture enters the system etc. There are areas that are not exposed that pose a potential problem and there can be a dynamic leak, where flexing in the sytems from road conditions move components into a postion that allows gas (R134A) loss. A ten year old vehicle will likley have multiple problems in my experience.
