What are the advantages of R-410A?
R-410A has a higher heat transfer coefficient than R-22. This is somewhat of an advantage for the manufacturer, but not so much for the end user. With higher transfer coefficients, one might be able to use a physically smaller system to obtain the same rating. For the person who is purchasing the unit, the efficiency would still be the same 10, 11, 12, 13, or higher SEER’s.
