R-404A is not compatible with R-12 systems due to differences in chemical composition and operating pressures. While R-404A is a hydrofluorocarbon (HFC) refrigerant, R-12 is a chlorofluorocarbon (CFC), and their properties require distinct system components. Converting an R-12 system to use R-404A typically involves replacing the compressor, expansion valve, and other components to ensure proper functionality and efficiency. Always consult a qualified technician for refrigerant conversions.
Mixing 404A refrigerant with R12 is not recommended, as they are incompatible and can lead to system damage, decreased efficiency, and safety hazards. R12 is a CFC refrigerant, while 404A is a blend of HFCs that operates at different pressures and thermodynamic properties. Additionally, mixing refrigerants can complicate recovery and recycling processes, making it difficult to maintain compliance with environmental regulations. It's best to use the specified refrigerant for your system.
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
No, if you mix them they will form a gel and ruin the compressor. You will have to have the system evacuated and replaced with the new refrigerant.
Only if you're trying to destroy your AC system. Never mix refrigerants.
no u can not mix the 2 togather it wil ruin the hvac system
No, you cannot.
no you can't. you must have the r12 removed and compressor oil then the valves need to have adapters installed so you can recharge the system no, but there are replacement freons (hot shot 414B) that can be added safely, after you empty the r12, and perform as the 12 did
No, you should not mix R12 and R134a refrigerants. R12 is a chlorofluorocarbon (CFC) that is being phased out due to its harmful environmental effects, while R134a is a hydrofluorocarbon (HFC) that is more environmentally friendly. Mixing them can lead to system damage, reduced efficiency, and environmental concerns. Always use the refrigerant specified for your system.
No, you should not mix R134a and R12 refrigerants in a 1993 Buick LeSabre or any other vehicle. Mixing these refrigerants can lead to system damage and reduced efficiency, as they have different chemical properties and pressure requirements. If you need to convert from R12 to R134a, it's essential to properly evacuate the system and replace any necessary components to ensure compatibility. Always consult a professional for refrigerant conversions.
The same amount is used as an R12 system.
It is not recommended.
They should never be mixed.
