| How does one figure how much r290 to use vs R12 or R134a? Same amount or do you need to adjust one way or another? Local AC parts place was telling me this new R1234abcdlgbtq+ bull crap they've forced on us is basically just propane anyway with a billion percent markup.
The flammability doesn't worry me since I've used that Duracool stuff you get at Napa that's just butane and when I blew a hose it sprayed in the precleaner of a tractor and the engine revved right up so if they can sell that why not just use propane anyway. | |
