What is normal AC pressure readings?
If you think that you have an issue with your A/C system but you are not sure which component is causing the malfunction it is a good idea to hook your compressor up to a pressure gauge. An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
What happens if car AC pressure is too high?
If your condenser has blockage or restriction of air flow, the high pressure side reading would be high while the low side readings would drop over time. To rectify this problem, you should remove and blockage and clear any debris. After removing the debris, check the readings again.

¿Qué es el refrigerante R134a?
El R134A se utiliza como refrigerante en aires acondicionado automotriz y doméstico, como en equipos con agua helada tanto en mercados comerciales como industriales. R-134A utiliza los nombres de tetrafluoroetano , Genetron o Puron, entre otros nombres, según el fabricante.
¿Cuál es la diferencia entre el aceite Poe y el refrigerante R-134a?
No es miscible con los aceites tradicionales del R-12 (mineral y alquilbencénico); en cambio su miscibilidad con los aceites poliésteres (POE) es completa, por lo que debe de utilizarse siempre con este tipo de aceites. R-134a es un refrigerante alternativo al R-12 para el retrofitting de la instalación o para instalaciones nuevas.
¿Cuál es la toxicidad de la sustancia R-134a?
Toxicidad y almacenamiento R-134a es una sustancia con muy poca toxicidad. El índice por inhalación LCL0 de 4 horas en ratas es inferior a 500.000 ppm y el NOEL en relación a problemas cardíacos es aproximadamente 75.000 ppm. En exposiciones durante 104 semanas a una concentración de 10.000 ppm no se ha observado efecto alguno.
