Part of your process should be to determine why the compressor (pump) needs to be replaced. In all cases the accumulator should be replaced when the system is opened. If compressors failed mechanically (not many reasons to replace otherwise) and no longer pumping refrigerant, then as part of it's failure and replacement should include replacement of the expansion valve and the condenser. The reason to replace these components also is that when the compressor failed it could/likely sent debris through the system. That debris will get caught in the expansion valve and can/will settle in the condenser for future movement through the system resulting in more damage. If you do not have the special equipment to evacuate the system and charge it with refrigerant you have an issue. Either acquire the equipment and properly learn all the variables what you are to do with them or pay someone to do those steps which you would be better off having them replace the components too. Good luck.

Andonko, did you read what machild just said?
​​​​​​He told you exactly what else and why it should be replaced at the same time.

Machild gave you a very thorough and well though out reply. Your reply... Not so much.
