You can find the refrigerant charge port on top of the air conditioner compressor. The refrigerant charge port will be labeled as the low pressure port.
Your recharge your air conditioner with the type of refrigerant which it was designed for.
Refrigerant System ChargeWARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM BEFORE PERFORMING THE FOLLOWING OPERATION.After all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerant charge can be injected into the system. For the proper amount of the refrigerant charge, refer to the Underhood HVAC Specification Tag. An R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 must be used to charge the refrigerant system with R-134a refrigerant. See the operating instructions supplied by the equipment manufacturer for proper care and use of this equipment.REFRIGERANT CHARGE CAPACITYNOTE: Always refer to the underhood HVAC Specification Tag for the latest fill specification for the vehicle being serviced.CHARGING PROCEDUREEvacuate the refrigerant system .A manifold gauge set and a R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 should still be connected to the refrigerant system.Measure the proper amount of refrigerant (1.88 lb) and heat it to 52°C (125°F) with the charging station. See the operating instructions supplied by the equipment manufacturer for proper use of this equipment.Open both the suction and discharge valves, then open the charge valve to allow the heated refrigerant to flow into the system.When the transfer of refrigerant has stopped, close both the suction and discharge valves.If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heater-air conditioner controls so that the compressor is engaged and the blower motor is operating at its lowest speed setting. Run the engine at a steady high idle (about 1400 rpm ). If the compressor will not engage, test the compressor clutch control circuit and repair as required.Open the suction valve to allow the remaining refrigerant to transfer to the refrigerant system.WARNING: TAKE CARE NOT TO OPEN THE DISCHARGE (HIGH PRESSURE) VALVE AT THIS TIME.Close the suction valve and test the system performance.Disconnect the charging station and manifold gauge set from the refrigerant system service ports.Reinstall the caps onto the refrigerant system service ports.Run the HVAC Control Cooldown test to verify proper operation.
A few things can cause this problem. Airflow or low refrigerant charge. 1st. airflow, or the lack thereof. could be caused by a dirty air filter and/or coil. blower motor not comming on or the compressor contactor sticking causing the compressor to continue to run without the indoor fan running. 2nd. Low refrigerant charge.

Normally, atoms do not have a charge, but if they are ionic, they have either a positive or negative charge, normally with the addition or loss of electrons.
The amount of refrigerant a unit contains depends on the size of the unit. That is the standard charge but the charge after the system is installed may be more or less. The system charge depends on the size of the refrigerant lines, the length of the lines, and the size of the unit.
if system is empty, u need to charge with correct amount of oil and refrigerant. the oil actually carries the refrigerant in the system if just recharging, buy the refrigerant that has oil already added, these are available at most auto stores
Low refrigerant charge?
