For the condenser and evap specifically?

Good plan of attack. Yes, the evap can be flushed in place with tubes attached to it, so can the condenser. It doesn't matter which way they're flushed, however I tend to flush "backwards" just so that if any crud is built up in the inlet side of things it doesn't get washed deeper into the tubes. No idea if it's better one way or another, but it makes me feel happy.
