3. vacuum test; I don't have the equipment to pressure test with dry nitrogen and do not have an electronic leak detector; and
4. Charge with PROPANE  -- sorry, couldn't resist that -- charge with correct amount of R-12. I don't need a 30lb supply -- is there a better source for small cans other than e-bay?
Now all I need is a few days off work. |
I am thinking about doing this myself. I think I'm going to flush with acetone and blow it out with compressed air.

I like that idea to use the old expansion valve. I'm going to look into that.
My plan is to disconnect the receiver dryer and the outlet of the condenser then flush the acetone through.
blow it out with compressed air and replace the dryer and expansion valve.
This is a DIY project with regular hand tools and anything that can be purchased from Ace Hardware.
i would like to hear any thoughts on this if it will work or should I just take it to a pro andhave them do it.
Thanks
