Why is the car air conditioning not very cold?

Reasons why the car air conditioning is not very cold: Dirty air conditioning filter: If the filter is too dirty, it not only allows more impurities to enter the car, which is harmful to health, but the dirt can also block the air conditioning filter, reducing the flow of cold air and making it seem like the air conditioning isn't cooling. It is recommended to replace the air conditioning filter every 10,000 kilometers. This ensures both the effectiveness of the air conditioning and the health of the passengers. Insufficient or leaking refrigerant: Refrigerant, also known as Freon, is responsible for cooling. If the refrigerant is lacking or insufficient, the cooling effect of the air conditioning will inevitably decline, or it may not cool at all. The solution is simple: take the car to a repair shop to have it refilled. If the air conditioning stops cooling again within a few months after refilling (normally, refrigerant should be refilled every 2-3 years), it may indicate a problem with the sealing of the pipes, causing the refrigerant to leak too quickly. In this case, professional help from a repair shop is needed. Aging or loose belt: If you hear a "squeaking" sound when turning on the air conditioning in the car, the lack of cooling may be due to a loose compressor belt. In this situation, the belt of the air conditioning compressor needs to be tightened. Belts are made of rubber and have a limited lifespan. If they are too old and worn out, they need to be replaced. Dirty condenser: If the condenser is not cleaned regularly, various impurities can completely cover it, preventing the condenser from dissipating heat properly. This is another reason why the air conditioning may not be cooling effectively.
I've been driving for over a decade, and air conditioning not cooling properly is a common issue. First, check if the refrigerant level is sufficient – if it's leaking, the cooling effect will naturally be poor. Next, see if the cabin air filter is dirty; too much dust reduces airflow and is unhygienic. If the compressor is malfunctioning, such as making strange noises or emitting odd smells, that's a serious problem. Poor condenser heat dissipation is also common, especially noticeable during summer heat. Sometimes wiring or switch failures can cause control malfunctions. I make it a habit to perform regular maintenance, testing refrigerant pressure and replacing filters during spring and autumn to avoid many troubles. Use the external air circulation mode appropriately when ventilating, don't always keep it on recirculation and stuff up the car. Getting it checked at a repair shop is the safest option – don't compromise safe driving.
