Serviceability of Heat Pump Refrigerant System
R-22/Freon has been phased out (Jan 2020). R-410A/Puron is also on the way out, with other refrigerants coming to the market in 2023 (R-454b in Jan 2023?)
1. If R-454b is slightly flammable, can it be used in older systems designed for the older refrigerants? (Doubtful)
2. Main question: should I delay replacing my AC (and gas furnace) with a heat pump for a couple of years so that I don’t get stuck with unserviceable refrigerant/system?
