Retrofitting A/C Systems

Up until the early 1990’s, all auto A/C Systems used a common refrigerant known as R-12 (Freon). It was relatively inexpensive and very efficient at transferring heat. However, it was eventually discovered that R-12 (along with all other CFC’s and some other substances) had a very sever negative impact on the earth’s ozone layer. Therefore, R-12 had to be replaced as the preferred refrigerant. Read more about retrofitting your auto A/C system....
Don't forget to see all the details about retrofitting your A/C system in the eBook titled Recharging and Retrofitting auto A/C systems. It explains all the steps required to complete a retrofit to get maximum cooling from your car's A/C system. Best of all, you get immediate digital delivery 24/7 and never pay shipping!

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.
