What to Do When the Air Conditioning Frequently Fails to Cool?

Here are the methods to address frequent air conditioning cooling failures: 1. Adjust the belt of the air conditioning compressor; 2. Replenish the refrigerant; 3. Clean the air conditioning filter; 4. Clean the condenser; 5. Check if the compressor capacitor has poor contact or is damaged. The method to turn on the car air conditioning for cold air is: 1. After starting the vehicle, turn the control knob to the cold air zone; 2. Turn on the AC switch and the fan. Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle cabin to an optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue.

I've encountered the issue of car air conditioning not cooling several times. The most common causes are insufficient refrigerant or leaks. If it doesn't feel cool, first check the system pressure; if there's a leak, you'll need to go to a repair shop for a refill. A clogged cabin air filter is another frequent reason – when dust accumulates for too long, airflow becomes restricted. Try removing it yourself for cleaning or replacement. Compressor failure is the most troublesome problem, with symptoms like humming noises during operation or complete unresponsiveness. This requires professional inspection, and replacement may cost around one to two thousand yuan. If the fan isn't spinning, it affects heat dissipation – check the circuit and relays. Regular maintenance can prevent these issues, such as cleaning the filter quarterly. If you can't solve it yourself, don't delay – high temperatures inside the car during summer can easily lead to heatstroke. Safety first – promptly visit a certified repair shop for proper handling.

After years of driving, I've encountered various situations where the air conditioning fails to cool. From an economic perspective, start with the cheaper solutions: check if the AC filter is clogged with dust—replacing it is inexpensive. If it still doesn't cool, it might be a refrigerant leak, and refilling it is also affordable. Avoid frequently turning the AC on and off to reduce load, and adjust the temperature settings reasonably. If the compressor fails, you'll need to spend more on replacement, so pay attention to unusual engine noises. I also recommend periodically adding fluorescent dye to detect leaks. Maintaining the system saves fuel and ensures comfort. Don't underestimate AC issues—they affect driving comfort and health.
