Is it okay to run the air conditioner while parked in summer?

You can run the car air conditioner in summer, but it's better not to as it may cause damage to the vehicle. Below is an introduction to automotive air conditioning systems: Introduction: Automotive air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin. It provides passengers with a comfortable riding environment, reduces driver fatigue, and improves driving safety. Structure: It generally includes refrigeration units, heating units, and ventilation devices. This integrated system makes full use of the limited space inside the vehicle, featuring a simple structure and easy operation, representing the internationally popular modern automotive air conditioning system.
Using the air conditioning while parked in summer is indeed possible, but requires caution. If the vehicle's engine is running, the air conditioning system operates normally; however, if the engine is off and relying solely on the battery, the compressor's high power consumption can drain the battery in less than half an hour, leading to starting difficulties or malfunctions. Doing this long-term is even riskier: when the engine runs at low speeds, incomplete combustion generates excessive carbon deposits, damaging engine performance while significantly increasing fuel consumption—wasting money and harming the environment. I recommend only using it briefly in emergencies, such as waiting a few minutes in an overheated car, preferably not exceeding 10 minutes, and keeping windows open for ventilation to prevent carbon monoxide poisoning. In short, this practice should not be frequent—it’s neither safe nor cost-effective. Prioritizing air conditioning use while driving is the better approach.
