How to Cool with a Manual Transmission Car's Air Conditioning?

Automobile air conditioning systems mainly consist of the refrigeration system, heating system, air delivery system, and control system. Press the A/C button and adjust the temperature to a lower setting. It absorbs heat from the surrounding environment, and then the low-temperature, low-pressure gaseous refrigerant is drawn back into the air conditioning compressor to start the next cooling cycle.
I've been driving a manual transmission car for several years, and using the air conditioning for cooling is actually quite simple. First, start the engine to ensure it's running properly, then press the A/C button to turn on the compressor for cooling. Next, turn the temperature knob to the low-temperature zone, such as around 18 degrees, and then select a fan speed. I think the most important thing is to remember to turn it on while driving, as the cooling effect is better when the engine speed is stable, and it won't make strange noises. If you feel the cold air isn't cool enough, it might be due to low refrigerant or a dirty filter. I've experienced this myself—just have the compressor checked during maintenance. Don't idle with the AC on for too long while driving, as it can increase fuel consumption and carbon buildup in the engine. I recommend using the outside air circulation in stop-and-go city traffic to keep the air fresh. Operating the AC doesn't interfere with shifting gears in a manual transmission—it's just as convenient as in an automatic. Even in my older car, it works fine.
As a manual transmission car owner, I think air conditioning cooling involves a few basic steps: start the engine after getting in the car, then directly press the A/C button to activate cooling mode, and adjust the temperature knob to a lower setting, such as below 20°C. Press the fan speed button to blow cold air. Remember, regular maintenance is key—replace the cabin air filter annually to prevent odors and blockages. I personally perform a check before every summer. If cooling is slow or there's unusual noise, it might be due to a loose belt or insufficient refrigerant, which requires professional servicing. Manual transmission gear shifting doesn't interfere with the air conditioning at all—it's fine to keep the A/C on while reversing or turning, saving fuel while staying cool for a more comfortable driving experience.
