How does R134a work in an AC system?
R134a, like most refrigerants, is a fluid that can easily be boiled into a vapor and condensed back into a liquid. Your vehicle’s AC system uses evaporation and condensation to cool your cabin air.
How does the R134a high and low side A / C pressure chart work?
R134a Pressure Gauge Chart This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
Where can I buy R134a refrigerant for my car?
R134a is a powerful, gaseous refrigerant that your vehicle uses to keep the cabin interior cool all year round. If your cabin is a little warmer than you’d like, it is likely time for a recharge.

Where is the expansion valve in an air conditioner?
This is known as a metering tube or an expansion valve and can be located either under the dash or under the hood near the fire wall. Its purpose is to change the pressure in the air conditioning system from high pressure to low pressure. Component 5: Hoses or lines. These consist of metal and rubber lines to carry the refrigerant.
Which is the low side of the R134a?
Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Why Is my Low Side AC Pressure High?
What’s the difference between R12 and R134a air conditioners?
However, there were—and are—some challenges to using it in an automotive A/C system designed for R12. The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used.
What should the PSI be on a R134a?
The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Having gone through all the above details, you are still wondering,
How to properly charge an Auto AC R134a?
The freon can should be upright so that refrigerant “vapor” is drawn into the low side. Remember that the Low side, also known as the suction side, normally operates as a “Low Pressure Vapor” state that is drawn directly into the compressor. You don’t want to “slug” the compressor by inverting the can…
