Is It Normal for the Noise to Be Loud After Replacing the Air Filter?
2 Answers
It is normal for the noise to be loud after replacing the air filter. The air filter is prone to accumulating a lot of dust, and simply blowing away the loose dust with compressed air or similar methods should suffice. However, if there is a malfunction, timely repair is necessary. Car maintenance is an essential method to maintain the normal functionality of a vehicle. Below is a detailed introduction about car maintenance: Overview: Car maintenance is a general term for the upkeep and repair of vehicles. It involves using technical means to diagnose faults in a malfunctioning car, identify the cause of the fault, and take certain measures to eliminate the fault and restore the car to a certain level of performance and safety standards. Additional Information: Car maintenance includes major repairs and minor repairs. Major repairs refer to restorative repairs that involve repairing or replacing any parts of the car (including fundamental components) to restore the car's perfect technical condition and fully (or nearly fully) recover its lifespan. Minor repairs refer to operational repairs that involve replacing or repairing individual parts to ensure or restore the car's working capability.
After I last changed the cabin air filter, I also encountered increased noise. At first, I thought it was normal, but upon closer consideration, it didn't seem right. Upon self-inspection, I found the filter was installed backwards, causing airflow obstruction and making the blower fan roar loudly. After reinstalling it correctly, the noise disappeared. A good filter shouldn't increase noise – excessively loud sounds should raise suspicions of incorrect installation or a substandard filter. An overly dense filter may slightly increase wind noise, but persistent loud noise is abnormal. Investigate promptly to avoid costly blower damage. While maintaining AC systems is important, the process requires caution. I recommend reviewing the installation manual or having a reliable shop double-check your work.
