I would have a charging port brazed into the line and charge my unit after first seeing if the mentioned cleaning was done.. You would otherwise be throwing away a unit that just needs freon... People sing whatever song cost you the most when wanting to sell something.
1. How do you braze a charging port without losing the existing Freon????
2. HOW and WHY would you charge a unit if it has lost Freon---IF it has lost Freon, there is a leak somewhere and the new Freon will just leak out if you do not find and fix the leak. These are SEALED systems with no way to leak other than a cracked/hole in a line.
