How to Determine If a Car's Air Conditioning Has Too Much Refrigerant?

[VonMichael]

Signs of overcharged car air conditioning include: 1. Poor cooling performance: The current value of the compressor power supply is significantly higher than normal, the compressor engages frequently, and there may be unusual noises during high-speed operation. 2. Uneven heat dissipation on the condenser surface: Insufficient heat dissipation on the condenser surface can lead to high-pressure protection after prolonged operation. Solutions are as follows: 1. Directly release the refrigerant: The refrigerant can be discharged into the atmosphere through the high-pressure pipe valve of the air conditioning system. However, if it is R12 refrigerant, direct release is not environmentally friendly and poses certain risks, so this method is not recommended. 2. Recovery: The most standard procedure is to use a car refrigerant recovery and recharge machine. The steps involve connecting the machine's hoses to the car's air conditioning high and low-pressure pipes, setting the required amount of refrigerant to be recovered, and then starting the machine to perform the recovery.
