Pontiac Sunfire a/c problem?

[Jessie]

I have a 2000 Pontiac Sunfire, the a/c hasn't worked in a while. If I put freon in it, it would blow really cold air, but it would run out. I took it to a mechanic about 2 weeks ago and had the compressor replaced and it was blowing warm air, so a couple of days later I took it back in and had the orifice tube and the dryer replaced. I got it out of the shop on tuesday and couldn't really tell if it was blowing cold because it was a little cold outside, but today is a warm day and its not blowing cold. I called the mechanic and he said to bring it back in, what else could it be? I confused because it was blowing cold before I had the compressor replaced, it would just leak out.

I'm confused as to why you keep going back to some guy who obviously doesn't know what he's doing and keeps stealing your money by selling you stuff you don't need.

You been ripped off big time. Bring it back and I will fix it "again". The problem at the start was a leak in system. Probably the O rings need replaced. All the parts replaced were not necessary. Are you sure the parts were even replaced? Replacing O rings is about a 2 hour job at most. O rings should be included in job as they are very cheap. Are you sure you have an orifice tube? most cars have expansion valves. You better get a refund as I don't believe the mechanic has done anything to your car except collect your money.
