Interactive A2L Refrigerant Pressure Chart & Refrigerants List
In our previous breakdown, The Ultimate A2L Refrigerant List & Pressure Charts (2026 Edition), we covered the compliance rules and manufacturing bans that are reshaping the industry. But when you are on a rooftop in 100°F weather, you don't need a history lesson—you need exact numbers.
Static charts are great for a quick reference, but they can’t cover every single PSI increment. That is why we built this interactive A2L refrigerant pressure chart tool.
Whether you are working with R-32 (Daikin/Goodman) or the R-454B blend (Carrier/Trane), this tool allows you to plug in your exact pressure and get the precise saturation temperature immediately. No interpolation math required.

Why You Need This Tool
The transition to mildly flammable refrigerants means working with tighter glide tolerances and higher discharge pressures. An A2L refrigerant list on a piece of paper can get torn, lost, or greasy. This digital chart is designed to live on your phone, giving you accurate data for:
R-32: The single-component standard for high-efficiency units.
R-454B: The primary replacement for R-410A in residential splits.
R-1234yf: The automotive and light commercial standard.
