The Evolution of HVAC Refrigerants
HVAC refrigerants have gone through many transitions over the last 40 years. R-22 and other chlorofluorocarbons (CFCs) were phased out in the early '80s because they had been proven to cause significant damage to the Earth's ozone layer. In their wake, hydrofluorocarbons (HFCs) such as R-134A, and especially R-410A, took their place.
R-410A is the current refrigerant that the majority of HVAC manufacturers have been using in equipment. While these new refrigerants don't harm the ozone layer, they have been proven to give off powerful greenhouse emissions. However, a new refrigerant is here to solve this issue.
Goodbye R-410A, Hello R-454B
Per new mandated regulations, all HVAC manufacturers must use A2L refrigerants in their products starting January 1, 2025. Any existing inventory stock of HVAC equipment using older refrigerants must be installed by January 1, 2026.
R-454B is a blend of R-32 combined with R-1234YF, a hydrofluoroolefin (HFO). The new R-454B has zero ozone depletion potential and carries a 78% reduction in global warming potential (GWP) compared to R-410A. Not only does R-454B exceed the EPA's requirements, but it is also more energy efficient, meaning it cools your home better while using less electricity.
What This Means for Greenville Homeowners
While you might be concerned that this refrigerant switch will necessitate buying a whole new air conditioning system, you shouldn't worry. Plenty of existing systems will be able to make the transition without any issues.
However, once current equipment is obsolete, there will be a significant price increase from HVAC manufacturers on equipment containing the new A2L refrigerants. If you are currently on the fence about needing a new system, now may be the perfect time to upgrade before price increases go into effect.
