I once encountered a condenser that was PACKED with grease.
I could NOT completely unclog it. I used 8 cans of foaming coil cleaner.
I gave up and told them that they may have to replace the condenser.
NOPE,,, they did just what you see above in the OP...
Those who dance, appear insane to those who do not hear the music.
Those who believe, appear ignorant to those who do not know God.
The liquid line isn't as bad as it looks in the picture. If I open the system up, a new piece will be made.
The suction filter is from when the unit got changed to R404a (new condensing unit). Line set was reused and the filter is for just in case the oil washes something loose from the rest of the system. That will go away if I open the system.
With greasy condenser coils, I take the condensing unit outside, use Renuz coil cleaner (I mix it 50/50 with water), spray it on the coil, hose it out, and reinstall.
