For example, R-410A unitary systems have the same superheat/subcooling levels as R-22. Many top trainers recognize that 410A's glide is minimal. R-410A refrigerant must be removed from the drum in a liquid state. The two refrigerants that comprise it boil at close to the same temperature. Therefore, for slight leaks, R-410A can be topped off.
