Does Long-Term Idling with Air Conditioning On Affect the Engine?

[Hope]

Long-term idling with air conditioning on does affect the engine. Keeping the car idling for extended periods with the air conditioning running can cause wear and tear on car components and is harmful. In principle, prolonged idling with air conditioning on is not recommended. The low idle speed of the engine results in poor cooling performance, failing to meet usage requirements. It also tends to cause incomplete combustion of fuel (gas), producing a large amount of exhaust gases, which can easily lead to poisoning and suffocation. Idling in place is an operational condition where the engine runs without load, only overcoming the frictional resistance of internal components without delivering external power. It maintains the engine at a lower stable speed. The idle speed can be adjusted by modifying the throttle opening and the idle fuel supply. Adjusting the idle operation must be performed under normal conditions, including proper engine temperature, appropriate valve clearance, normal ignition system, good sealing of all pipes, fully open choke valve, and tightly closed throttle valve. During adjustment, first, unscrew the throttle opening adjustment screw to achieve the lowest stable engine speed.
