Why does the air conditioner make a crackling sound?
1 Answers
The air conditioner makes a crackling sound because the plastic parts inside the dashboard expand and contract due to heat when the heater is turned on in cold weather. This sound will disappear once the temperature stabilizes, which is a normal phenomenon. If you are still concerned, it is recommended to have it checked at a 4S shop. The car air conditioner is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to the optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. The car air conditioner generally includes a cooling device, heating device, and ventilation device. This combined system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
