It's generally recommended to turn off the AC before turning off the car engine. This practice helps avoid potential strain on the vehicle's battery and compressor when you start the car again. Here's why:
- Compressor Load: When you start the car with the AC already on, the engine has to power the compressor right from the start, which can put additional load on the engine and battery.
- Battery Life: Turning off the AC first reduces the electrical load, which can help prolong the battery's life.
- Moisture and Odor Prevention: Turning off the AC before the engine can also help dry out the evaporator, preventing moisture buildup, which may otherwise lead to musty odors inside the vehicle.
For optimal care, it's best to turn off the AC, then turn off the engine.
