Using R12 in a R134a system can cause several issues and even damage the air conditioning components. Here are some reasons why you should not put R12 in a R134 system:
1. Different Pressures: R12 operates at a higher pressure compared to R134a. Using R12 in a R134a system can lead to excessive pressure buildup, putting strain on the compressor, hoses, and other components, which could result in leaks or failures.
2. Lubrication Issues: R12 and R134a require different types of lubricants for optimal performance. Mixing these refrigerants can result in incompatibility, causing insufficient lubrication and increased wear and tear on the compressor and other moving parts.
3. Performance and Efficiency: R12 and R134a have different thermodynamic properties. Using R12 in a R134a system can impact the system's cooling efficiency and performance, leading to reduced cooling capacity and increased energy consumption.
4. Environmental Concerns: R12 is a chlorofluorocarbon (CFC) refrigerant known to contribute to ozone depletion. Using R12 in a vehicle with a R134a system is environmentally irresponsible and could result in legal consequences due to regulations aimed at phasing out CFCs.
5. Compatibility Issues: R12 is not compatible with the seals, gaskets, and other components designed for R134a systems. Mixing refrigerants can lead to leaks, performance issues, and accelerated aging of the system.
If your vehicle's air conditioning system was designed for R12, it's crucial to continue using R12 or consider converting it to an R134a system by a qualified professional. Mixing or replacing refrigerants without proper knowledge and equipment can be dangerous and harmful to both your vehicle and the environment.
