What are the reasons for poor cooling effect of car air conditioning?
2 Answers
Poor cooling effect of car air conditioning may be due to insufficient refrigerant; excessive refrigerant; clogged filter screen; air entering the air conditioning system; insufficient heat dissipation capacity of the condenser. Here are the solutions for car air conditioning not cooling: Clean the radiator and condenser: The radiator and condenser can be rinsed at home with a water hose, but never use a high-pressure water gun, as the condenser is made of very thin aluminum material and can easily be deformed by high-pressure water. If it is too dirty, it is recommended to go directly to a 4S store for cleaning. Replace the air conditioning filter: It is recommended to replace the air conditioning filter once a year, but check it regularly every six months. Check if the air conditioning lacks refrigerant: If it lacks refrigerant, simply add some, and also check for any refrigerant leaks.
A few days ago, the air conditioning in my car wasn't cooling effectively. After having it checked by a mechanic, I discovered several common issues. The main problem was insufficient refrigerant, commonly referred to as a refrigerant leak. Poor system sealing can lead to gradual loss, so timely replenishment is necessary. Secondly, the air filter was too dirty, with dust blocking the vents and restricting airflow, which naturally weakened the cooling effect. It's recommended to replace it every six months, especially before summer. Compressor failure is another hidden issue; if there are unusual noises or vibrations when the AC is on, it might be due to a faulty compressor bearing. Additionally, the condenser at the front of the car can easily get clogged with mud or leaves, affecting heat dissipation. Gently rinsing it with a hose after parking can help. Insufficient fan speed or a loose belt can also reduce efficiency, which can be fixed by simple tightening or replacement. Lastly, pay attention to usage habits—avoid keeping the system on external circulation all the time. Switching to internal circulation on hot days cools the car faster, and setting the temperature to medium is most efficient. Addressing these points can save you from major troubles.
