How Long Can I Keep My Car AC On While My Engine Is Running But Car Is Parked?
It is generally not recommended to keep your car's AC on while the engine is running but the car is parked, as this can put a strain on your battery and potentially lead to it draining. However, there are a few factors that can affect how long you can safely leave your AC on in this situation, such as:
- Outside temperature: The hotter it is outside, the harder your AC will have to work to cool your car, which will drain your battery more quickly.
- Condition of your battery: A weak or old battery will not be able to handle the load of running the AC for as long as a new battery.
- Size of your car: A larger car will require more energy to cool than a smaller car, so the AC will drain your battery more quickly.
As a general rule of thumb, it is best to avoid leaving your AC on for more than 15-20 minutes while your car is parked. If you need to keep your car cool for longer periods of time, it is better to turn off the AC and open the windows or use a portable fan.
