A/C compressor went out in the fall and snapped my belt. Local mechanics gave me an estimate of 900-1100 to change the compressor along with the lines and what not. Being that it was the fall and i didn't have the money i bought a shorter belt and bypassed the a/c compressor for the time being. Well its almost summer here in NC now and i need A/C again. Does anyone know if id be able to only change the compressor and then recharge the system to save money or do all the components have to be done?

 

I should think that if you clean the lines out good, just changing the compressor should be adequate to the task..... Be sure to replace the orfice tube though.... Not sure if that is serviced separately, or if you need to replace that entire line.... I *think* you can get the tube from the parts store.....

 

In my past experience, I have been able to just replace the compressor, recharge with a couple cans of R134 from wallyworld and never had an issue. If your only opening the system long enough to replace the compresssor, your likely not going to get that much moisture in the system. If the compressor was tore up though you might have metal particles floating around in the system that can clog the expansion valve/orifice tube (different manufacturers use different terminology, but it's the same thing). Only way to know is to replace it and refill and see what happens. TAhen go from there if more work is needed. I have done this on 4 vehicles now and have not had issue. If the system has been open, I would recommend also replacing the dryer.

These are my experiences. Yes, a system should be vacuumed properly, etc, etc, but I never had an issue not doing that. I would also throw a can of compressor lubricant in there as well.
