R-134a refrigerant in a Chevrolet Suburban is typically added to the air conditioning system. You can find the service ports for R-134a on the A/C system, usually located near the compressor. It's important to use the correct port—low-pressure and high-pressure—when adding refrigerant to ensure proper functioning. Always refer to the vehicle's service manual for specific instructions and safety precautions.

Is r-22 Freon compatible with r-134a freon?
The 1993 Aerostar does not use R-134a. It uses R-12.
R-134a is 95% less damaging to the ozone layer than R-12.........
HFC-134a and R-134a refer to the same chemical compound, which is 1,1,1,2-tetrafluoroethane. The designation "HFC" stands for hydrofluorocarbons, indicating its classification, while "R" is a designation commonly used for refrigerants. Therefore, HFC-134a and R-134a are different names for the same substance utilized in refrigeration and air conditioning systems.
No. Per the EPA website, there is no sales restrictions on R-134a.
No. Per the EPA website, there is no sales restrictions on R-134a.
If I remember correctly 1993 vehicles had R-134A installed at factory
No
Passage of the Clean Air Act. R-12 depletes the ozone - R-134a does not.
No, you should not mix R-134a with an R-22 system. R-22 and R-134a are different refrigerants with distinct properties and are not compatible. Using R-134a in an R-22 system can lead to system inefficiency, potential damage, and could violate environmental regulations. If you need to switch refrigerants, it's best to properly reclaim the existing R-22 and retrofit the system for R-134a or another compatible refrigerant.
HFC 134a chemical name CH2FCF3(Tetrafluoroethane)
