Is It Normal for a Car to Idle at 1000 RPM with the AC On?

[KevinLee]

Normal. The idle speed of a car varies between cold and warm engine conditions. Generally, a well-functioning engine in a warm state idles between 550-800 RPM. If the engine idles at 1000 RPM when cold but decreases as the engine temperature rises to a certain level, this is considered normal. Relevant information about idling is as follows: 1. Introduction: Idling is an operational state of a car where the engine runs in neutral gear. The engine speed during idling is referred to as the idle speed. Idle speed can be adjusted by altering the throttle opening size, among other methods. Idling essentially means the engine is "producing power without doing work." 2. Driving Idle: When the car is in gear without pressing the accelerator pedal or when the accelerator pedal is released while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is known as driving idle.
