After replacing my accumulator in my truck I realized that I could not do the installation of new freon because im not liscenced. The problem is that I need 3 pounds of R-12 to fill my system. However, I'm debating on switching the system to 134a. Here are the pros and cons i came up with.
R134a
Pros: Cheap and easy to find. Still manufactured. The new "Environmentally Friendly Standard"
Cons: Not as strong (doesnt blow as cold). Smaller molecule so systems are more leak prone.
R12
Pros: Strong and Cold. Doesnt leak as easily. Would save me money on not having to buy a compressor/condenser.
Cons: No longer manufactured. VERY expensive ($40 a pound ). "Not environmentally friendly."
Im wondering what you guys would do in this situation. The truth behind the R12 environment problem is a coverup so that the company that was producing it could renew their patent with a new type of freon . Would you spend the $40x3 = $120 plus a liscenced flush/charge, or would you purchase a new compressor/condensor for $500 and not have to worry about extremely expensive charging fees? Right now im leaning towards charging with R12.
