Why Isn’t the Car AC Cooling Efficiently?

As summer approaches, many people inspect their air conditioning systems to ensure they can withstand the high temperatures. Over the years, some have fallen into the trap of inefficient car air conditioning. Various components can contribute to this issue, each with its specific function in the cooling system.

Causes of Inefficient Car Air Conditioning

In this article, we will discuss in detail the reasons behind inefficient car air conditioning and provide some tips to maintain the system’s effectiveness during the summer.

Reasons for Inefficient Car Air Conditioning

The inefficiency of car air conditioning can result from several components. Let’s delve into them:

Compressor Damage

The air conditioning compressor is the heart of the system. It compresses the refrigerant gas, raising its temperature. The gas then passes through the condenser, turning into a liquid and initiating heat exchange processes that lead to the release of cold air. Compressor damage is a significant cause of weakened air conditioning, even when set to maximum cooling.

It’s worth noting that the expected lifespan of the compressor depends on the car’s mileage and the usage style but typically ranges between 130,000 to 160,000 kilometers.

Leakage in the Condenser

After the compressor pressurizes and transfers the refrigerant gas to the condenser, the condenser converts the gas into a liquid by lowering its temperature while maintaining high pressure for optimal cooling. However, a specific malfunction or a hole in the condenser can prevent the gas from cooling and transforming into refrigerant.

Refrigerant (Freon) Depletion

As mentioned earlier, refrigerant (Freon) is the primary substance for obtaining cold air after being pressurized and converted into a cooling liquid. A gradual decrease in cooling efficiency and the air conditioner’s inability to cool during the car’s idle state may indicate a decline in refrigerant levels.

AC Filter Blockage

Despite its primary function of purifying air from dirt and impurities before entering the cabin, the AC filter accumulates deposits over time. When the accumulation becomes significant, the air struggles to pass through, requiring periodic filter inspection and cleaning. It is advisable to replace the filter completely after covering a distance of 50,000 kilometers.

Electrical System Issues

Like any electrical system in a car, the AC system relies on the car’s battery for power. If there’s a fault in the battery or its connections and wires, the AC will not function efficiently.

How to Maintain Your Car’s AC?

  • Regularly perform maintenance and inspect parts that require cleaning, such as the filter.
  • Check the refrigerant level periodically.
  • Avoid parking the car in direct sunlight.
  • Ventilate the car by opening windows before turning on the AC to reduce the load on the system. Gradually increase the cooling level when activating the AC.

In conclusion, these were the main reasons for the inefficiency of a car’s air conditioning, based on the components of this system.
