What Causes Dual High Pressure in Car Air Conditioning?

[JeremiahLynn]

Introduction to the causes of dual high pressure in car air conditioning: Excessive refrigerant, air entering the refrigeration system, or insufficient cooling due to condenser failure can all lead to dual high pressure in car air conditioning. When both the high and low pressures are higher than normal, it is referred to as "dual high." Common faults usually involve air in the system or excessive refrigerant. In such cases, the solution is to re-vacuum the system and add refrigerant. Below is an introduction to air conditioning maintenance: 1. Comprehensive air conditioning inspection: When using the air conditioning for the first time in summer, it is essential to inspect the air conditioning system. For example, check the refrigerant and whether the air filter is too dirty through the liquid storage tank, and check for any foreign objects in the radiator. 2. Pay attention to air conditioning cleaning: The air filter should be replaced regularly to prevent moldy odors. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.
