Should the car air conditioning AC be turned off or on in summer?

In summer, when using the air conditioning, the AC button should be turned on. The AC button is the cooling switch for the car's air conditioning system. If the AC button is not pressed, the air conditioning will not cool. Here is some related information about car air conditioning: 1. In hot summer, when the AC button is turned on, the temperature control should be adjusted to the blue position. For automatic air conditioning, you can set a temperature and then press the AUTO button, and the automatic air conditioning will adjust the interior temperature accordingly. 2. The car air conditioning AC is the switch for the compressor. The car air conditioning system includes not only the compressor but also the condenser, evaporator, expansion valve, etc., which work together to compress and transport refrigerant vapor.
As someone who's constantly on the road, I believe the car's AC must be turned on during summer. Without it, the car interior feels like a steamer – extremely uncomfortable, especially during traffic jams when sweat pours down, affecting driving safety. The AC quickly dehumidifies and cools, making the air dry and comfortable. Using just the fan to blow hot outside air actually makes things worse. My routine is to open windows for two minutes to vent hot air after getting in, then close windows and turn on AC with recirculation mode – this saves fuel while being effective. Regular checks of AC filters and refrigerant are crucial to prevent odors or malfunction. Don't set the temperature too low; around 25°C is perfectly comfortable and fuel-efficient. Remember, running AC in extreme heat protects electronic components and prevents battery overheating.
I prioritize energy efficiency and environmental protection, so I use the air conditioning wisely in summer. Turning on the AC does increase fuel consumption by about 10-20%, but for comfort and safety, it's necessary. I first open the windows to let out the hot air for a few minutes before closing them and setting the AC to around 26°C, using the recirculation mode to minimize hot air intake. This balances economy and coolness. Without the AC, the cabin temperature can spike, wasting energy on the fan instead. The AC's dehumidification function also prevents window fogging, enhancing driving safety. For short commutes, I might start with the fan to cool down, but for longer drives, I switch to AC mode.
I have some knowledge about cars, and turning on the AC in summer is a wise choice. While the compressor's operation increases engine load, running the system under high temperatures can cause more damage. Using the AC helps protect both the engine and the battery. Start the car first, then turn on the fan to circulate air before pressing the AC button. Adjust the temperature to a comfortable level—avoid setting it too low to prevent overworking the system. The AC also efficiently removes humidity and defogs windows, improving visibility and ensuring driving safety. Replace the filter when it gets dirty to maintain fresh air inside. Overall, the benefits outweigh the drawbacks, so there's no need to skip this step.
