Mechanic Juan José Ebenezer has issued warnings regarding the practice of turning off a vehicle engine while the air conditioning is still active. 

According to Ebenezer, cutting the ignition immediately causes the compressor to stop abruptly, which leaves the air conditioning circuit immobile and saturated with moisture. This habit may result in increased component wear, higher fuel consumption, and the development of unpleasant musty odors inside the cabin. Experts recommend managing the air conditioning system before stopping the vehicle to maintain air quality and prevent compressor failures.
