Anyone know if any suppliers are still selling any nitrogen charged R22 units.  Looking for a 4TON

I'll see what they have.  Most of the stuff on their site says out of stock/discontinued.

Yea, right.  I saw  Aire-Flow Md# 13ACDN048, Nit Charge,  you have to call them for availability. Good luck

Another question,

Anyone used any R22 Drop in replacement refrigerant ie R407C or M099 ??

if so what are the steps on using these replacement refrigerants in a dry unit. do I need to change / add oil.   Does a dry charged unit come with oil already in the compressor?

I've used MO99 and been happy with it; straight drop in, no oil changes.

Ok cool.  I've read some people are adding 4-8oz of POR send and 1oznof supco88 to their conversions.
