Natural Refrigerant HVAC Systems That Cut Your Energy Bills
Real Energy Efficiency Without Toxic Refrigerants
Cut Your Energy Bills Without Greenwashing
When the HVAC industry moved away from R410A and R407C, it quietly replaced them with R32, R454B, and R454C and called it progress.
What they're not telling you is what's inside these alternatives, and why they still struggle when temperatures push to extremes.
There's a better way. One that performs when it's freezing and when it's scorching.
Get Lower Energy Bills. No Greenwashing.If it uses less energy and leaves no trace, it's a natural refrigerant.
How Natural Refrigerants Compare To Synthetics
Not all low-GWP refrigerants are created equal. R32 and R454B are marketed as the green alternative, but both still contain PFAS compounds, cost more to run, and face EU prohibition by 2027. The comparison below paints a different picture.

R454B and R454C
R32 and R410A
Zero. Propane is a naturally occurring hydrocarbon.
R1234yf fraction degrades into TFA, which is a PFAS compound.
R410A contains PFAS due to its R125 fraction but does not directly degrade into TFA.
Breaks down naturally; does not degrade into hydrogen fluoride, carbonyl fluoride, or TFA.
R32 fraction has an atmospheric lifetime of approximately 5 years and degrades into hydrogen fluoride, which is lethal.
R1234yf fraction breaks down in approximately 11 days and produces TFA, which is a PFAS compound.
R32 has an atmospheric lifetime of approximately 5 years and degrades into hydrogen fluoride, which is lethal.
R410A has an atmospheric lifetime of approximately 30 years and degrades into lethal carbonyl fluoride and hydrogen fluoride.
