In the context of an R134a compressor, "134" refers to the refrigerant R-134a, which is a hydrofluorocarbon (HFC) used in air conditioning and refrigeration systems. The number "134" denotes its chemical structure, specifically the presence of 1,1,1,2-tetrafluoroethane. R-134a is known for its low ozone depletion potential and is commonly used as a replacement for R-12, which is more harmful to the environment.
No you don't have to change the A/C Compressor.
Yes!
newer vehicles, such as a 99 jeep, all use 134-A refrigerant.
R134a
No use R22. R134A is for automotive applications.
r134a
It compresses the refrigerant (probably r134a) and pushes it through the ac system.
With proper retrofit... Yes
You are low on refrigerant, google R134a...
too much oil in system or compressor not working properly are some possibilities
See a specialist. System needs to be purged, leak checked & Recharged.....
I think all American cars from 1993 forward have 134 installed at factory
