What is the chemical makeup of HCFC refrigerants?

HCFC refrigerants are hydrochlorofluorocarbons, molecules that include hydrogen and chlorine in their makeup, along with fluorine and carbon. That combination means the best description is that they are hydrogen/chlorine based. While fluorine and carbon are also parts of the molecules, the defining feature for identifying HCFCs is the presence of hydrogen together with chlorine. Saying they’re chlorine-based or hydrogen-based alone would misrepresent their composition, and labeling them fluorine-based would ignore the hydrogen-chlorine relationship that characterizes HCFCs.
