So I was having issues with my ac on my 2011 f250. It would cool some but the compressor would constantly turn on and off. So I took it to Krause Family Ford and had them look at it. They originally said it was the evaporator core but then later called back and said the compressor came apart and it along with the condenser and filter needs replacing. They quoted $2,300 parts and labor which I thought was way too high since I could buy the parts anywhere for under $600. So they finally brought it down to just under $2k. After them having it a week I got it back Friday and it worked fine. Then yesterday I didn't use it since it was colder. Now today when I use it the compressor is still cutting on and off just like before. It cools slightly better but nothing like it should. The lines are also hot which on Friday when I checked them they were ice cold. I looked at what all was replaced and what the Ford service book says should be replaced when a compressor is replaced due to contamination and they replaced the compressor, condenser, and the high side switch but did not replace the thermostatic expansion valve or the ac pressure relief valve which according to the Ford book says should be replaced. They also charged me for refrigerant when I know it was full since I had just charged it myself. It probably was overfilled actually. So now I am not even sure it needed the parts that were replaced. Before I took it there I felt the compressor and it didn't spin freely so I told them from the beginning I didn't think that was it. I could feel the pistons working when I turned it. This is so frustrating. It seems like I just can't find a place to take my truck to have work done. The last place I took my truck for a slow coolant leak told me I had a blown head gasket even though I told them it was very rare for a 6.7 to have that. A week later I crawled under the truck and found the coolant leak from an o ring on a coolant hose connection. The time before that the Ford specialist place I took it to re-installed the belt wrong and it shredded it on the way home. They did pay for me a new one from Oreillys but I had to install it myself. They were supposed to check my hpfp but had no idea what they were doing either. Then about 4 years ago I had the upper oil pan gasket replaced at Hardy Ford dealership and now it's leaking again. This is exactly why I do all my own work. I was going to do this ac work but I really didn't want to do it and the whole reason I had them do it is so I wasn't just throwing parts at it and so I could get the 2 year warranty.
Has anyone had a similar problem with their ac or have any idea what it could be?

 

 

Sounds like there is a leak somewhere in the system. I repair systems and a lot of parts are suppose to be replaced cause u can not flush them out. it could be they cut an oring by accident when reassembling the system.

 

 

I've already looked and I have a new compressor, condenser, and a pressure switch installed. The Motorcraft condenser comes with a new filter. They supposedly flushed the system and according to the Ford repair manual I have which is Ford's workshop manual they were supposed to replace the thermostatic expansion valve and pressure relief valve which they didn't. Not sure if it matters or not. I just don't want them saying well we were wrong and you also need an evaporator core so now pay us X amount. I'm of the mind that I took it to you, you diagnosed it, you made the repair you said was the problem, I paid, now if something else is wrong then it's on you to fix it regardless if it costs you more since obviously you didn't know what the problem was in the first place. The other issue I have is this is my work truck I tow with so I'll not have a vehicle while it's back at the dealership. After finding out what it was I was just going to do it myself and buy the Motorcraft parts from Rockauto and buy a new vacuum pump, I already have some gauges. I could have bought the compressor, condenser, o rings, txv, and a new pump for about $500. I was out of town and figured I'll save myself the trouble and have them do it.

 

 

I worked as an auto mechanic for several years. Things can go wrong no matter how careful. New parts can be effective, installs can go bad, often you are working in very tight areas and not easy to get to. You should give them a chance to make it right.
