Reminder: Brake Cleaner + Welding = Death

It's generally just wise not to mix or heat chemicals if you don't know what the result will be. Brazing or soldering tubing in a refrigeration system can release similarly dangerous gases with the older CFC and HCFC refrigerant types. The newest HFO types are flammable so you don't want to do that, either. I don't know about the HFCs used in between but I would assume it'll kill me unless known otherwise.

I just had a friend ask if i could solder in a service port on his commercial fridge with it charged and top it up.i told him fk no! Cheap bastard can pay for recovering,etc just like any other customer!
