Vehicle A/C Evacuation and Recharge Service Mechanic If the air coming out of your vehicles’ vents is not as cold as it used to be, the issue may be that your car has run low on refrigerant ( R-12 Freon in older cars, R-134a in 1995 and newer cars).  As time goes on, small amounts of refrigerant leak from the system and if there is not enough refrigerant, the AC will not blow cold air. For low Freon levels the solution is simple – put more refrigerant in the system. Recharging your vehicle with refrigerant can bring up the pressure to correct levels. If your vehicle’s AC system is working but not blowing cold air, a refrigerant recharge will give your system back a frosty punch.

Here are some general guideline for A/C system pressures and temperatures based on ambient outside temperature. Remember that these are a guideline and your actual temperatures and pressures will vary depending on humidity in the air and the condition of your system. When running the car at idle to check the freon level it is a good idea to have a water hose handy and spray water on the a/c condencer. The condencer is located in front of the radiator.

, run fan on High with all windows open and engine at 1500 rpm. High side pressure in PSI should be about 2.2 to 2.5 times outside air temperature in degrees F. Example if it's 90 degrees F, high side should be no higher than 225PSIHere is a useful trouble shooting chart for systems currently running on freon R-134aTrouble shootingLow Compressor Discharge Pressure1.
