What should r134 pressure be?
between 22 and 57 psi
The normal running pressure of R134A is between 22 and 57 psi.
What should AC gauges read on car?
What are normal AC gauge pressures when the system is running? Generally speaking, you want around 27-psi on the low side and 200 on the high side.
What happens if you add too much R134a?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.
What should AC gauges read on a car?
How cold should R134a get?
That fact explains why compressor manufacturers limit the condensing temperature for R407C to around 145–150°F (60°C–65°C) whereas for R134a compressors, the top limit for condensing temperature is 158–175°F (70–80°C) for air condi- tioning applications.
What are normal AC pressures?
An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
What is the difference between R134 and R134a?
Some people use the terms R134 and R134a interchangeably, as seen in a casual search of automotive websites and storefronts, but they aren’t identical. The same number and type of atoms make up R134 and R134a, but the arrangement differs. Although R134 is technically a refrigerant, it’s less efficient at moving heat.
Can you put R12 in a R134?
Instead you can convert an R12 system to an R134a system with a few parts and some basic tools. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. Releasing R12 directly into the environment is dangerous and punishable by law.

What is are in R134?
R-134 means 2 carbon atoms, 2 hydrogen and 4 fluorine= tetrafluoroethane. Today we work on three refrigerants and see what best among them and what is advisable. R-290. Now that you have learn where the number come from, but which is the best among the three. This the common and most popular refrigerant for the domestic refrigerators.
