I bought a can of aerosol ac flush how will I flush the system? Will I have to remove every component? Should I flush the evaporator? As for the condenser can I flush through the line that goes from the ac compressor and then out of the line that goes to the accumulator? Please help this is my first ac flush.

Im going to replace the accumulator and all o-rings. Then I was hoping to flush out all oil and refill, so I know how much is in there. I can get the vacuum pump and gauges to refill afterwards.

Short and direct answer... you cannot.

The understanding of different system designs, component designs, failure scenarios, and how they effect the decisions required as to how, when, and which way to flush. Also, information regarding basic chemistry and undeniable physics principles will help guide your decision as to what to use for flushing. This is all in the paper in my signature.

But you said, "I read it but dont see where your going with it."

yes I did read it, it was saying how every system is different and you need to understand the flow before you flush. Can I actually flush it with the aerosol. I know he said no but what is the reasoning? I was also thinking about blowing compressed air though after flushing the lines and components to remove the rest of the solvent.

The aerosol can does not contain enough solvent and does not generate enough solvent velocity to flush a hose let alone the entire list of system components in need of cleaning to properly remove all the oil.

Ok I just read the technical paper again, and am just curious now that will the aerosol can atleast remove the oil? It is not like the compressor blew up in my system.

Ok in your opinion how should I flush it, how would you do it?

At a minimum. I would use a Hecat Plusator and Hecat flush. Remove each item and flush separately flushing both direction until clean.
