I've got the tools and the parts to do a leak repair.. (I've done one in my life).
But, all I have for refrigerant is R410A.. And maybe a can of R134A..
Isn't there some substitute for R22? That doesn't cause global warming?

R290 or R1270 will do it. For nonflammable gases, others have used air duster successfully (can't remember what R number it is). Most everything nonflammable has high ozone depleting or global warming potential.
