Does Running the Air Conditioner for 1 Hour While Parked Harm the Car?

[VonAnthony]

Running the air conditioner for 1 hour while parked can significantly harm the car. 1. Carbon buildup: Prolonged idling can lead to carbon buildup in the engine, which causes incomplete combustion of gasoline and results in engine shaking. Carbon buildup reduces engine power, leading to uneven and gradually diminishing power output. 2. Increased fuel consumption: This raises fuel costs, adding to financial burdens. 3. Difficulty starting: Cold starts become harder, meaning the car struggles to ignite. 4. Safety hazards: Severe carbon buildup in the combustion chamber can cause engine knocking, produce noises during low-speed acceleration, damage pistons and crankshafts, and lead to engine overheating, severely compromising vehicle safety.
