Is R-152a a good alternative refrigerant?
They may not be laboratory tests, but we’re glad that ChevyBob took the time to do some excellent tests on three identical vehicles. One charged with R-12, one with R-134a and one with R-152a. The tests were conducted on the same day at the same time. Like we said, they may not be laboratory tests, but they sure do provide some excellent information about how these three refrigerants perform in the auto A/C system.
