Does idling with the air conditioning on harm the car?
1 Answers
Idling with the air conditioning on can harm the car. It is not recommended to keep the engine idling with the air conditioning on for extended periods. Not only does it wear out the engine, but prolonged use of the air conditioning in recirculation mode will gradually pollute and degrade the air quality inside the vehicle, potentially producing harmful gases. The power consumption of the air conditioning only accounts for a small portion of the engine's idle energy. However, when idling with the air conditioning on, the engine not only drives the air conditioning compressor but also needs to maintain the normal operation of the power steering and brake booster pumps. The latter two functions are completely unnecessary when the car is parked, and keeping them running is a significant waste of power.
