What are the impacts of forgetting to turn off the car air conditioner?

Forgetting to turn off the car air conditioner can drain the car battery. Here are some maintenance tips for the car battery: 1. In-car electricity usage: To maintain the car battery, avoid listening to the radio loudly, charging mobile phones, or using air pumps when the engine is off. Prolonged use can easily lead to battery depletion, and frequent depletion will significantly reduce the battery's lifespan. 2. Long-distance high-speed driving: Regularly driving on highways not only helps remove carbon deposits from the vehicle but also fully charges the battery. Generally, driving on highways for more than an hour can fully charge the battery, keeping it in optimal condition. 3. Avoid prolonged vehicle inactivity: If the car is not used for an extended period, disconnect the battery cables or start the vehicle every two weeks and drive it for several dozen kilometers to ensure the battery remains functional. 4. High-power electrical connections: Many car appliances, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power. Do not directly power these devices using the car battery. Instead, start the vehicle first and then connect the electrical devices.
Once I forgot to turn off the car's air conditioning, and the next morning the car wouldn't start at all because the battery was drained. The AC system still consumes battery power to run components like fans even after the engine is off. This incident frustrated me for days—a completely dead battery requires recharging or replacement, incurring significant additional repair costs. Worse yet, if the AC compressor operates under no-load conditions for extended periods, it can wear prematurely or seize up, shortening its lifespan. Now, I've made it a habit to check that the AC is off before shutting down the engine. This not only avoids unnecessary troubles but also saves on fuel costs. Even when parked, an active AC continuously drains power, indirectly wasting fuel or battery capacity. In the long run, maintaining this habit reduces environmental pollution too. I recommend everyone take a few seconds to confirm the AC status before parking—such small habits truly matter.
Leaving the air conditioning on can be quite troublesome. I often encountered this issue when I was a taxi driver. The battery power can be quickly drained, especially when the AC keeps running the fan and control system while the car is parked, potentially causing starting difficulties. Additionally, internal components of the AC system, such as the compressor and fan motor, are prone to overheating or premature aging during continuous operation, increasing maintenance needs. If neglected for a long time, the battery lifespan can be significantly shortened, making replacement expensive and time-consuming. I've also noticed that in hot weather, leaving the AC on while the car is parked outdoors can draw in extra dust, clogging the filter and reducing efficiency. To prevent this, I've developed a habit of double-checking the switch every time I park, ensuring peace of mind. Since adopting this routine, my car runs more smoothly, saving me a lot of hassle.
