How Often Should a Car's Air Conditioning System Be Cleaned?
1 Answers
Generally, a car's air conditioning system should be cleaned once a year. If the driving environment is harsh, the cleaning interval should be shortened. The reason for annual cleaning is that the air conditioning filter has a limited lifespan, typically around one year. Methods to determine when to clean the air conditioning system: If the air blowing from the vents has a musty, smoky, or sour odor, it needs cleaning. Additionally, if cooling efficiency decreases or fuel consumption increases, these are also signs that cleaning is required. Steps to clean a car's air conditioning system: Remove the air filter and open all windows. Start the engine but turn off the AC, set the system to maximum external circulation (4th fan speed), and direct the airflow toward the driver. Shake the cleaning agent with its tube attached vigorously and spray it into the intake vent in front of the passenger seat. As foam emerges from the vents, be ready to wipe it away with a cloth. After completing these steps, turn on the AC and let it run for 10 to 15 minutes. Then, turn off the fan and the engine, allowing dirty water to drain from the vehicle's bottom drainage pipe. After a few minutes, observing a large amount of dirty water on the ground indicates that the air conditioning cleaning is complete.
