Can the freon be replaced in the armstrongs with the modern r-34 gas or
r-22 or should I find r-12 to do the job with?
I may add, r-12 is getting very difficult to find and quite pricy.
The newer gas would be of a benefit because if the problem happens again it will be a whole lot easier to deal with.
I want to keep this unit as it is a rooftop freezer box!
I wish my homes AC worked as well as this almost 30 year old unit does!

Gino,
R-12 &r-134a are both for automotive use only. R-22 & it's replacement R-410 are for small appliances @ rv airconditioners , residential a/c , dehumidifiers, etc.
You can NOT use r-12 or 134a in place of r-22. It is a compatability point. You also can not mix different refrigerants. Again because of compatability. Your Armstrong a/c would use r-22. By EPA laws only certified refrigeration service persons may handle it.
By mixing refrigerants you not only would do serious damage to the unit but also create a mess. Serious hazard, a mixture that can not be reclaimed & possiable health injury.
These are only a few reasons this should only be handled by a licensed tech.
I never looked to see what the charge was.........
I have a tech that will service the unit with r-22.....................
Thanx for the replys folks as the information was needed before we went any further.
