Why Does It Take More Than 10 Minutes for the Car Air Conditioning to Cool?

After the car air conditioning is turned on, the compressor may experience start-stop cycles. Generally, the compressor stops when the interior temperature drops to a certain level and resumes operation when the temperature rises above the set value. Possible reasons for this issue include: refrigerant deficiency, requiring a refill; air leaks in the ducts, affecting cooling efficiency; or an abnormal expansion valve in the air conditioning system. Solutions for slow cooling in car air conditioning are as follows: 1. Poor Heat Dissipation: In most cases, intermittent operation of the air conditioning system is caused by poor heat dissipation. Clean and inspect the radiator fins. 2. Temperature Sensor Issue: The problem might lie with the temperature sensor. The air conditioning evaporator contains a temperature sensor that stops the compressor when it detects the evaporator temperature is too low. Therefore, check if the sensor is damaged. 3. Ice Blockage: If there is moisture in the air conditioning system, it may freeze and block the pipes when cooling starts, leading to intermittent cooling cycles as the ice melts and reforms. Inspect and address any moisture-related issues.
