Normal Ac Pressure Gauge Readings вђ Ricks Free Auto Repai The normal pressure ranges shown in these images are based on specific conditions: • the engine running at 1,500 rpm • the air conditioning system turned on • the compressor engaged. accounting for the ambient temperature is essential when evaluating if the pressure readings fall within an acceptable range for normal ac operation. Note: high humidity and airflow velocity across the evaporator and condenser have a direct effect on pressure readings. how to test ac pressures with a manifold gauge. 1, set the ac controls to max and recirculate 2. blower set to high speed 3. close the doors. windows can be open. 4.
Auto Ac Gauge Reading Chart Essential tools for diy car ac repair. to diagnose and fix car ac problems yourself, you’ll need the following tools: 1) manifold gauge set: you can’t accurately diagnose an ac system using low side pressure readings. manifold gauges are inexpensive to purchase or rent. find a reasonably priced manifold gauge set on amazon . this kit. Air conditioning testing thermometer. $7.79 (02 2024) automotive ac pressure chart for air conditioning systems with r134a: for auto air conditioning r134a systems: at idle condenser inlet temp 170 to 180, condenser outlet temp 135 to 150 (usually a 30 to 40 degree drop in temperature across the condenser), evaporator outlet temp 45 to 55. The r 134a and r 1234yf pressure charts are for guidance when using a c pro ® recharge kits, refills, and gauges. the charts are intended to help provide an understanding of a vehicle’s air conditioning system pressure, which can be helpful during the diagnostic and recharge processes. be sure to consult the instructions provided with your a. High 150 low>10. expansive valve open or leak. check valve or complete dye test. high 100 low 100. compressor does not engage. check wiring. note: the most ideal pressure readings are around 150 high and 30 low. warning: remember, venting 134a refrigerant into our atmosphere is illegal and bad for our environment.

Manifold gauge readings. an a c manifold gauge set measures refrigerant pressures inside an air conditioning system. an automotive air conditioner has a high and low side, divided by a metering device and the a c compressor. a compressor pulls low pressure vapor from the suction side with the clutch engaged. it then compresses and discharges it. For each set, the hoses are color coded, with red corresponding to the high pressure side valve and blue corresponding to the low pressure side. run your air conditioning at its maximum capability until the inside of the car is cool. on your manifold gauge set, open the valves for both high and low to check the pressure level.
