How much will an air compressor being fixed cost to be fixed?

If the compressor is locking up, then you are correct that it will need to be replaced. However, you normally don't want to just replace the compressor. Normally when they lock up, they put metal in the system and that needs to be removed or it will hurt the new compressor.

So that means you need to replace the accumulator and the orifice tube.

However, I am attaching the info below on the compressor as requested.

Basically, the part is about $300.00 and then labor will be about $200.00. There will be some shop fees but that will put you in the ballpark.

Please let me know what questions you have from this point, and we can go from there.

Thanks
