Why is the Sagitar's air conditioning not cooling?

Here are the reasons why a car's air conditioning may not be cooling: 1. Insufficient cooling: First, determine if the air filter is clogged, leading to reduced airflow. Many cases fall under this category. If the air is cool enough but the airflow is insufficient, it may feel like the cooling is inadequate. Replacing the air filter can resolve this issue. 2. Excessive dust on the evaporator: If the air filter is not clogged but the airflow is still low, and the air conditioning system shows no faults, the issue may be due to excessive dust on the evaporator, requiring an air conditioning cleaning. Generally, it is recommended to replace the air filter twice a year—once in winter and once in summer. The air conditioning should be cleaned once a year or every two years, depending on usage frequency. Cleaning should be done in summer, as winter does not require cleaning for heating purposes. 3. Dirty condenser: A dirty condenser is another reason for poor air conditioning performance. The condenser is located in front of the radiator, closely adjacent to it, and is used to dissipate heat from the refrigerant. It can often become clogged with debris like lint, leading to poor heat dissipation and reduced cooling efficiency. 4. Low refrigerant level: If the refrigerant level in the air conditioning system's pipelines is insufficient, the pressure decreases, reducing the amount of heat removed and resulting in inadequate cooling. If there is no refrigerant at all, the system will not cool at all. Refrigerant needs to be refilled, and any leaks should be checked. 5. Faulty components in the air conditioning system: For example, a damaged compressor or expansion valve may require inspection and repair at a 4S shop.

I've been driving for many years and have seen quite a few cases where the Sagitar's air conditioning isn't cooling properly. Most of the time, it's due to a lack of refrigerant—that's the Freon, right? If it's leaking or hasn't been topped up enough, the air coming out just won't be cool. The compressor is also pretty important; if it's worn out or stuck, the entire AC system is done for. Then there's the condenser getting too dirty—summer driving leads to mud and debris buildup, blocking heat dissipation and affecting cooling. If the cabin air filter hasn't been changed for too long and clogs the airflow, the air coming out will be weak and warm. I've dealt with similar issues myself: first, check the refrigerant pressure, replace the filter, and if that doesn't work, I recommend going to a 4S shop for a full inspection—don't delay and risk damaging more parts. Also, avoid keeping the AC on recirculation mode for too long before driving; it traps heat and consumes more energy over time.
