Parts list for A/C service

[JD3020]

When i bought my f450 back in December the HVAC system worked perfect, no issues with it. Did an engine swap a couple months ago and now i'm ready to get the A/C going again. The system has been sitting open since then, so what all parts will i have to replace? I went through the same thing with my OBS when i did the engine swap in it, but i can't remember what all i had to replace. LOL

Any O-rings you removed, the orifice tube and the dryer. You will need to pull a vacuum for at least an hour after getting it all assembled.

It's a good idea to pull the blower fan and blow out the evaporator fins with compressed air.

Is that something i can do myself, or do i have to take it to a shop?

If you have a vacumme pump or are able to rent/borrow one all the other stuff to do is easy.

Is it ever necessary to replace the whole system in one of these trucks?

Shouldn't be.
