My heat works great, but my AC is nonexistent. Just blows out normal air, which in this weather is quite hot and unpleasant.
I had the freon refilled two years ago, but I haven't used the car in over a year so I don't know when the AC stopped working. It was working up until the last time I used it, anyway.
I was told it would be about $85 to refill the freon, but that it wouldn't do me much good if I had a leak.
How long should a freon refill last, and how do I know if I have a leak, and if I do, what must be done to repair it?
