Signs that cars need to replace air conditioners immediately
Weak air conditioning, no effective cooling
One of the most obvious signs of air conditioning filtering being stuck is the ineffective air conditioning system. When the air cannot circulate well through the filter, the air flow from the air conditioner will be significantly weakened, reducing the ability to cool or warm. If you find that the air conditioner is no longer as cool as before even though you have adjusted the highest fan level, it may be time to change the filter.
There is an unpleasant odor in the car
dirt leakage can accumulate dirt, mold and bacteria, leading to a foul smell in the cabin. If you notice a moldy or strange smell when turned on the air conditioner, the cause may come from a dirty filter. Replacing the new filter not only helps remove unpleasant odors but also improves the air quality in the vehicle.
Air conditioning system causes unusual noise
When the air conditioner is blocked, the fan must work harder to push the air through the filter, causing a louder noise than normal. If you hear a whistle or whistle when turning on the air conditioner, it is likely that the cabin is too dirty and needs to be replaced immediately.
Dust appears in the car compartment
A dirty cabin filter will not be able to retain small dust particles, causing them to penetrate the interior compartment. If you see a lot of dust appearing on the dashboard, seats or windshield right after turning on the air conditioner, this is a sign that the filter is no longer working effectively and needs to be replaced.
A slight cold air mass is not even in the vehicle
If you find areas in your vehicle that are cooler or warmer than other locations, air conditioning can be the cause. When the wind flow is obstructed, cold or hot air cannot be distributed evenly in the vehicle, causing discomfort to passengers.
Allergies and discomfort when driving
A clean cabin filter helps remove pollen, bacteria and allergens. If you or a passenger in the car suddenly feels itchy nose, continuous sneezing or shortness of breath while using air conditioners, it may be a sign that the cabin filter has lost the ability to filter the air effectively.
How long should you change your air conditioner once?
The frequency of air conditioning filter changes depends on the environment and vehicle usage conditions. According to the recommendation, you should replace the air conditioner every 10,000 - 20,000 km or every 6 - 12 months. If the vehicle often drives in a dusty, polluted environment, the filter replacement time may need to be shortened.
