Hi, We just bought a used Adler/Barbour Cold Machine that's in great condition but used R12. What is the recommended replacement for R12 and can we just shoot the stuff in ourselves? LaDonna

R-12 NO NO

The old cooling sys. must be purged of all coolant and the oil therein. This is done with a vaccume process. This process also reclames all the old freon. The sys. will then be recharged with the new oil and coolant. A licensed teck is the only one leagelly allowed to do this in the USA. You can take it from there. However, if this unit is working fine, then don't mess. The old addage, "If it aint broke, don't fix it". Ken

R12 is good stuff.

LaDonna: R12 is good stuff, it is just very expensive. You should not and cannot really do this yourself unless you have the proper equipment. I would get the unit installed and then have a certified 'R-man' charge the system for you. There are also some other considerations when it comes to changing the types of coolants, so they can advise you on that too.

R12 and the EPA

As a HVAC tech, you cannot charge it yourself, take note that the last time i checked it was about $900.00 for 30#, going rate to customer was around $60.00 a pound. there are other replacements for R12, you will need to talk to a tech for what is used in your application. Some do not require that the oil be removed, they neutralize it with additives. No matter what, make sure you pull a good vacuam on it and HOLD it for at least 15 minuits. If you have a good tech, he will make sure that the job is clean and well done. Then you should get years of use from it. Make sure you keep the coils clean and the cooling fan as well. I have been out of the service side for a few years and new stuff comes out all the time. Here is one tip, never worry about offending a service man to leave for any reason, he is working for you, if you dont think he is taking good care of the work area tell him to stop. As a general rule I always tell my men that if you or your truck and tools look sloppy, your work will too. Its your boat, he is there for you, want a differant tech, tell him so and call for another. Did i just go off on a rant or what. sry
