The replacement cycle of a car compressor is generally about 10 years, but the specific replacement time still needs to be determined based on factors such as the quality of the compressor, frequency of use, climate region, and user frequency of use.

When choosing a car air conditioning compressor, you should consider the vehicle model adaptability, cooling efficiency, energy consumption ratio, durability and brand reputation. Choose original parts to ensure easy installation, stable operation and convenient maintenance.
