help need AC service in Pascagoula

We are on our vacation and our Armstrong AC is failing, Started the trip with the AC bringing the temp down to 74 and below now we are lucky to get to 80. As some of you know most RV service centers will only replace a unit. We are not ready to give up on our Armstrong AC unit, I think we just need to charge the system with R22. Can I do this myself?? I know I need the freon and a set of gauges. Where can I get these items? Or does anyone know of a honest AC service man that will work on the unit in the Pascagoula MS area.

We don't want to give up early on this our maiden voyage for our new to us AS.

I would suggest finding an honest A/C service person. Technically, you need an EPA license to handle R-22. You might have a pinhole leak in your system, which requires evacuation of the system and a pressure test to locate. For this, you need a vacuum pump, guage set, evacuation cannister, replacement R-22, a filling device that will let you add the exact amount of refrigerant required for the unit, a couple of new Shrader valves, a torch and brazing solder and some replacement copper. It is rather involved. I don't do this type of service even though I have the EPA Universal air conditioning and refrigeration license due to the very high equipment costs, the outrageous processing fees for R-22 and the high liability factors involved. OTOH, if your system is just needing a little R-22 to top it off, then it should not be a problem with the proper equipment!

This is why the RV industry went away from the Armstrong type units and went with the new hermetically sealed units that are cheaper to replace than repair.
