The stuff was used, as an example, for BB "machine guns" and to chill glassware for mixed drinks and so advertised on TV. Why so cheap? Off patent.

They banned those in favor of CFC's because they were safer - according to DuPont's lawyers. Anything they can patent and do. 1234yf is the new patented expensive stuff.

They could add a pump down solenoid on the condenser liquid line. Leak sensor sends signal to air handler board, board sends 24v signal with extra wire to condenser. Solenoid closes and pumps down condenser. Compressor shuts off on low pressure switch. Only added 1 extra part and ran extra wire to condenser which usually there is spare wires already ran with the thermostat wire This will also prevent the whole loss of the refrigerant in the house. Refrigerant will be trapped between the compressor reed valves and the liquid line. Will only loose what is in the evaporator and suction line

Did after market automotive A/C yrs back and moved on to other things, so I did have my certificate for refrigerant handling etc,.. in the early 90's when 134a was fairly new to replace r12,there was a gas from a Chinese chemist called GU 2015. it was MORE efficient than 12 and was non cfc gas. Magic stuff. But 134 seemed to be the biggest thing on the market and Dow AND Dupont were cornering that market. We did buy some 2015 and used it for retrofits and customers were really happy with it. It was a straight replacement for 12. I heard of some shops replacing 12 with propane and I thought how crazy is that ?? Flammable refrigerant?? I bought a small window ac unit for my apt, and IT has flammable refrigerant. Crazy
