Does idling with the AC on have any impact?

[CharlotteLee]

Keeping the AC on while the car is idling has a slight impact on the engine, as it can lead to carbon buildup, particularly around the exhaust pipe tailpipe, and increases fuel consumption. Although idling with the AC on does not cause significant harm to the car, it is still advisable to minimize this practice. Here is some additional information: Car Air Conditioning: The car air conditioning system is a crucial comfort feature in vehicles, capable of both cooling and heating. When the AC is in cooling mode, the compressor clutch engages, causing the engine to drive the compressor. The compressor then continuously compresses the refrigerant and delivers it to the evaporator.
