Although there may be a temptation to simply treat A2L refrigerants as equivalent to ammonia with respect to flammability hazard, ammonia really is an entity unto itself. Like an A2L, it exhibits a low-flame velocity in flammability tests, but ammonia has the unique safety advantage of a strong and unmistakable odor that is typically present long before the onset of a flammability hazard. All of the current A2L refrigerants, on the other hand, are odorless.
R-134a has a global-warming potential (GWP) of 1,430. This means it traps 1,430 times as much heat per kilogram as carbon dioxide does over a 100-year period. Because R-134a has such a high GWP, the U.S. Environmental Protection Agency (EPA) listed R-134a as an “unacceptable” refrigerant for certain refrigeration and air conditioning applications under its Significant New Alternatives Policy (SNAP) program.
To prevent unnecessary return visits (aka callbacks) for your company or future issues for your customers, here are some helpful items to remember when completing a repair.

And, with consumers demanding even greater energy savings and comfort control, they are already hard at work on the next generation of heat pumps.
