So, you need:

(1) to clean the coil & fins (copper & aluminum ??)
(2) to flush and remove oil inside the evaporator coil
(3) need procedure to clean the coil - item (1)
(4) need procedure flush the coil - item (2)

Item (3) procedure is too easy that you do not need any suggestion from others while
Item (4) is too dangerous (using high pressure OFN) if you're not an aircon or refrigeration technician.

As i see it, what you need is just find an aircon technician and you will have no problem solving this cleaning problem.

Hope you will heed above advise. :rolleyes:

thanx brain, yes ur guess is item(4) , how we can flush, i m not a aircon technician,
what the meaning of (OFN)
just ur idea explain to me, have any links to this problem

OFN=oxygen-free nitrogen.
It depends on size and quantity of coils to be flushed. If it's one small coil, it's better to replace it altogether.
If more than one or size matters, then follow the triple evacuation procedure, provided that not all of the oil will escape.
