Can I Turn on the Air Conditioning When the Car is Parked?
1 Answers
You can turn on the air conditioning when the car is parked. However, it will not have a cooling function, and prolonged use can easily drain the battery. Therefore, it is not recommended to keep the air conditioning on for long periods when the engine is off. If you need ventilation, switch to the external circulation mode to allow fresh air to enter the cabin. Below are some maintenance tips for car air conditioning: 1. Do not randomly adjust the air vent direction: When using the air conditioning, failing to adjust the airflow direction properly can reduce its effectiveness. Based on the principle that cold air sinks and warm air rises, the correct approach is to point the vents upward when cooling and downward when heating. 2. Regularly start the air conditioning in winter: In regions with milder winters, some car owners may not use the air conditioning at all during the season. Prolonged disuse can cause the rubber seals to age and the lubricants on internal components to dry out. Starting the air conditioning periodically allows the components to be lubricated and maintains their condition, so it's best to run the air conditioning at least once a week in winter. 3. Avoid prolonged continuous use of the air conditioning: Keeping the air conditioning on for too long after starting the car can increase the pressure on the condenser, leading to wear and tear on the cooling system. Therefore, avoid using the air conditioning for extended periods. If the cabin temperature has reached a comfortable level, turn it off and restart it later. 4. Ventilate and cool the car before using internal circulation in summer: During hot summers, many drivers habitually switch to internal circulation as soon as they enter the car, thinking it will cool the cabin faster. However, since the interior temperature is higher than outside, this approach is less effective. Upon entering the car, first open the windows for ventilation and activate external circulation to expel the hot air. Once the cabin temperature drops, switch to internal circulation.
