Why R32 refrigerant?

Updated: Nov 24, 2020

Why does TEIGE recommend the use of R32 refrigerant gas in the air conditioners we install?


Air conditioners transfer heat while circulating refrigerant gas between your outdoor and indoor units. The refrigerant gas is the medium for conveying that heat energy. R32 is a fairly modern refrigerant gas that has entered the market. If you have researched air conditioning in the last few years, you have likely heard about the move to this modern refrigerant.


Up until 1994, the industry relied heavily on a refrigerant gas R22, a hydrochlorofluorocarbon, that when released into the atmosphere, depleting the earth's ozone layer. Thankfully, R22 has been phased out of use. From 2006 onwards, the industry moved to a newer gas, R410a which is also a hydrochlorofluorocarbon but more efficient. Although R410a has no ozone-depleting potential, it's global warming potential still remained an issue.


Fast forward to R32, a refrigerant with zero ozone-depleting potential, but also offers one-third of the global warming potential of R410a, the most common refrigerant gas used today.
