Rising summer temperatures are driving increased air conditioning use in vehicles. However, many drivers are neglecting a crucial step when turning off their cars: fully switching off the AC before ignition. Experts warn that repeatedly starting the car with the AC still engaged can strain the compressor and other components. This practice can lead to premature wear and tear, potentially resulting in costly repairs. The issue stems from the compressor remaining engaged even after the engine is off if the AC isn’t manually deactivated. Regularly performing this simple action can prolong the life of the AC system and maintain optimal performance, ultimately reducing environmental impact and repair expenses.
