Another item on your A/C system that will probably need to be replaced is the orifice tube. Our A/C sat dry for quite some time as well. It ended up that only 3 items on the whole system needed repairs: Compressor clutch, leak in ac line, & the orifice tube. After the clutch was replaced and the leak was sealed, the system ran at a very high pressure. Replaced the orifice tube (which totally clogged and very nasty looking), and the system ran perfectly fine! Before the compressor would only cycle on for about 4-5 seconds. Now it never cycles off because the pressures stay so low. -Robert vin 6585
