Has anyone had problems with flushing the condenser and evaporator after a compressor failure?

Yes, it is very difficult but VERY important to do and do WELL.

You will need high volume compressed air and a flush gun made especially for the purpose. The flush gun consists of a cylinder in which you pour the flushing agent then pressurize through a shrader valve. A hose is connected so that it gets liquid and has a blow gun with a rubber tip so that you can seal off the connection where you are applying it to achieve good pressure and flow.

After forcing flushing agent through the component, use your high volume compressed air, also with a rubber tipped blow gun to force everything out. REPEAT, Repeat, and repeat.

For flushing agent get some mineral spirits in good quantity. Flush the component as well as possible with the mineral spirits, then flush out the mineral spirits residue using regular a/c system flushing agent that you get from the a/c supply house. This will save a lot of money because the mineral spirits are much cheaper than the flushing agent.

Do not use only mineral spirits because it leaves a slightly oily residue.

The two most important things about flushing are; flush THOROUGHLY and don't leave ANY solvent in the system AT ALL.

Failure to do an adequate flush after compressor failure is almost a certain guarantee that you will be replacing the new compressor soon.

Good luck,

Thanks for the reply. I pulled the compressor,drier and disconnected all of the fittings as well as the expansion block.I flushed the entire system,cut open the drier and the only component that had heavy contaminated was the discharge line from the compressor.The compressor was full of grey/black fluid.The discharge line has a filter or muffler that seems to have caught most of the debre. This same line has no blockage and is now clean. Should this line be changed as well? Thanks
