Cooley On Cars
Chill out with your climate controlsAlways fiddling with your car's climate controls? Here's why.
It's amazing, but the climate control system in your car is probably way more advanced than the one in your house these days. Let's learn how to get the most of all these features and functions that I think most people never bother to really understand. [MUSIC] I like to look at a climate control system in terms of four or five buckets of what it does. And the first, most important one is, are you in manual mode or are you in auto mode? If you're in auto mode, all you gotta do is set a temperature and that's it. The car should seek that temperature, it's gonna modulate the amount of heat or cool source it has It's gonna modulate the air flow, which vents it's using, fan speed, and turning all of those up and down or on or off to seek that target temp. You've also got the ability to decide if you wanna have single or dual systems. Many cars have dual zones. You can sync them together, so the driver's knob controls everything. Or you can separate them, so driver and passenger can set their own temperature and their own flow of air. In a good climate system, that's all you gotta do, and this can be a really short video. Unfortunately, climate systems aren't always that smart, so here's the next thing to think about, and that is your flow controls. Your flow controls are things like blowing down Down to the floor, blowing up to the defrost, or blowing across the center vents. Those are usually your main three levels. And related to flow is the recirc button, or recirculation. What this does is that it takes the air in the car and basically keeps recirculating it as opposed to drawing in a lot of air from the outside the car. You use this in a couple typical situations. One, when you're driving through some place where the air's really stinky. Like when they've just done some asphalt paving or you're driving by the sewage plant. Gross. Turn on the RECIRC or if you're in a really hot place and you wanna cool down fast. RECIRC takes cold air from the air conditioning that's on, makes it colder, and blows it back into the cabin. It's an infinite loop of cold and the quickest way to cool off. It may be called max air conditioning or recirculation. They tend to be the same thing. But if you're gonna roll your own and not use a lot of these sort of short cuts and automatic settings then you've got two things to deal with besides the flow we just talked about. One is the temperature. In manual mode, when you set the temperature up and down. You're really telling the car to give me a certain amount of air conditioning and maybe heater heat as well. Sometimes it'll use both to hit a certain temperature of air but then you're deciding what to do with that. It's not seeking a target temp anymore, It's all on you. And of course fan speed decides how much you wanna blow that mix of air you just created into whatever vents you just selected. Honestly, I like to use an automatic system. But know this, every car's automatic system seems to be calibrated very differently. 71 in one car does not equal the same feel as 71 in another car. The numbers are kind of relative, but once you find what number is comfortable for you, the car should do a really good job of keeping the cabin air.
