After the system runs for a while, raise the RPMs up to about 1,500. The system should be about 25 to 30 psi on the low side and 200 to 250 psi on the high side. If the ambient temperature is higher or lower than normal (70 to 80°F) the pressures will go up or down accordingly.

On the high side, R-134a pressures usually run 2.2 to 2.5 times the ambient temperature entering the condenser. So, if the ambient temperature is 80°F, you'll see high side pressures running between 176-psi and 200-psi. on an R-134a system. At 200-psi. the refrigerant entering the condenser will be around 130°F.

1. Determine Ambient Air If the temperature of the air is 55°F or below, do not charge the vehicle. It is also always recommended to use a charging hose with a gauge. The refrigerant packaging should contain a chart like the one below for determining what pressure to charge the system depending on the ambient air temperature.

Car 1: Outside air was 95°F (35°C) with 85% humidity Car 2: Outside air was 75°F (24°C) with 38% humidity We measured the temperature from the central vent with an AC test thermometer and we got the following results: Car 1: Air temperature coming out the vent was 58°F (14°C) Car 2: Air temperature coming out the vent was 49°F (9°C)

Low car AC refrigerant — How to diagnose — Ricks Free Auto Repair

1. With the engine OFF for at least 30 minutes, read the low and high-pressure gauges. 2. Measure ambient air temperature at the vehicle (do not use weather service temperatures) WITH A THERMOMETER. 3. Compare the pressure readings to the pressure-temperature chart below

the temperature chart for different types of pressure gauges, including

The high side components of an air conditioning system, such as the compressor, condensing coil, and fan unit used to cool the condensing coil are located outside of the conditioned or refrigerated space, and will be immersed in air at ambient outdoor temperature, say 72 °F. Here is where the magic of air conditioning occurs. As long as the.

Refrigerant Pressure Charts The R-134a and R-1234yf pressure charts are for guidance when using A/C Pro ® recharge products and gauges. These charts can help provide an understanding of how much pressure is in your vehicle's air conditioning system, which can be helpful during the diagnostic and recharge processes.

• You must know ambient air temperature. Measure temperature about 1-ft in front of the grille. This is really important. Don't go by the temperature from a news or weather service. It must be the temperature of the air coming into your car's condenser. • You must know the type of system in your vehicle — orifice tube

When the ambient air temperature hits 80° or 90° Fahrenheit (27° to 32° C), the outlet air temperature should be in the 33° to 48° Fahrenheit (3° to 9° C) range. Due to the varying ranges, it's essential to check your manufacturer/vehicle information manual to see the exact A/C temperature during specific temperature conditions.
