What happens when a hydrocarbon such as propane or butane is used in an A/C system? The performance of the A/C system is actually not hampered by the use of these gases, however, the safety of the user of the vehicle is. If there is a leak in any part of the A/C system or a front-end Why can't we continue to use R12? Since the early 1970s scientist have been watching a hole grow in the ozone layer.  And because of this ozone problem, over 150 countries agreed to stop the production of CFCs.  This agreem What do all OEMs (car manufacturers) currently use in all of their cars? All OEMs use R134a and have done so in all cars beginning with model year 1995. However, some cars prior to 1995 had factory R134a systems installed. Many service technicians believe that R-134a is on How many refrigerants are currently "acceptable for use" in cars today? Twelve (12) alternative refrigerants are currently legal for use in mobile air conditioning systems today. Can I legally use HC-12a / OZ-12 for use in R134a cars, or in industrial refrigeration applications? The EPA, while not having jurisdiction over the use of replacement refrigerant for R134a, does not allow the use of these refrigerants as replacement refrigerants for R134a.

Yes . There have been some documented cases where technicians have found 100% hydrocarbons in an A/C system. In this situation, it is acceptable to vent this gas –recovering this would cause too much Is air in refrigerant a problem? Yes . Air is a contaminant of refrigerant that can enter an A/C system or cylinder and create A/C performance problems.   Non-condensable gasses (NCG or "air"), which are mainly comprised What air purge systems are available today? Recovery/Recycling Machines Temperature/Pressure Measurements Neutronics Air-Radicator™   Recovery/Recycling Machines can be used to purge air from A/C systems or cylinders. This Do I need to do anything special to retrofit an old R12 system to a R134a system? Yes . According to EPA regulations, the use of any alternative refrigerant to replace R-12 requiresat a minimum that; Unique service fittings be used in order to minimize the risk of cross-cont What does R-22 do to a typical MVAC (mobile vehicle air conditioning) system?
