Useful Tips On How And When To Use the AC Circulation Button In Your Car

Ever wonder how to actually use the AC circulation button in your car?

Alright, so by now, we would all have already seen the button on our cars that is in the main image, right? Some of us know what it is and what it is for and also how and when to use it, but not everyone, so today, we here at DSF are going to teach you all about this magical and somewhat confusing button to all our readers. Let’s begin.

AC circulation

Okay, so here is one useful tip regarding the AC circulation button in cars. Most all vehicles will have this button somewhere in their centre but many of us are clueless on when to use it. Well, the easy answer is to use it in the summer and turn it off in the winter, but what about in Malaysia where we have less seasons and no winter?

Moreover, we have all heard the jokes about Malaysia also having four seasons (hot, scorching hot, raining and raining until flooded) but on a more serious note, the most general rule of thumb would be to turn on the internal AC circulation when we are in extreme heat (midday, heatwave, etc) and turn it off when in rain or fog.

Okay, so now that we know when to use it, let’s see what it does. The AC circulation button simply takes the air from inside the car and recirculates it in the cabin instead of pulling fresh air from outside, which is what usually happens. Thus when the button is off, air is pulled from the outside as it is the default.

So on days when it is so hot outside, you can fry an egg just by leaving it out in the hot Sabah sun, if you do not turn on internal AC circulation, then your car will essentially pull hot air from outside to try and cool the inside. Sounds silly right? Well, it is and it also damages the AC system in your car as it is forced to work double time.

On top of that, using the AC circulation feature will get your car cooler and will decrease the wear and tear on your AC system. So if your car has been baking in the sun for a while, we recommend you to roll down your windows and turn off AC circulation for a bit to get rid of the hot air inside the car before turning the AC on.

Lastly, when stuck in traffic it is best to turn on AC circulation as if your car is pulling air from the outside, you are also pulling in all the pollutants and carbon monoxide from all the traffic. While this does not necessarily harm your AC system too much it is bad for your health so stay safe, keep the AC on internal circulate!

Well, we hope this helps and be sure to check out everyday to learn more about your car everyday.
