East of Broken Bow | If it went 34 years and just now needs a charge, maybe splurge for the real stuff on ebay. It's actually not as expensive as it used to be.
Or, get the stuff that's compatible. The paperwork will always say not to mix, but generally you can.
I have added Red Tek directly into R 12 systems, and know someone who used Freeze Zone in his, neither of us had problems. Basically, both of us sprung a slow leak, and had to start adding a can or two a year.
If the leak persists, or the compressor seems weak, do a Sanded conversion and switch to 134 all together. | |
