This article offers a method to cool your car quickly on a hot day. Open the windows slightly, close them, then open and close the driver’s door quickly a few times to move ambient air in and out of the cabin.
I found that when I had a Honda, I could roll down all the windows and open the sunroof from 30 feet away. When I got to the car it was much cooler and easy to enter. My Tesla doesn’t have this feature but I’ve found that using a windshield sun block has a substantial positive effect. Anyone else have ways to cool the cabin quickly on a hot day?
Here is what works in the south… 1st off crack your windows just a tiny little bit unless you have rain deflectors, any amount helps…
Start the vehicle, roll windows down an inch or two, turn A/C on high but fresh air, once the cabin temp has equaled the ambient temperature, then turn on recirculate and roll up windows tight…
IF you start off on recirculate then you are trying to cool the cabin temp (say 120° plus) instead of the ambient temperature(say 95° plus), since it is easier to cool 95° air vs 120° air… with the windows cracked and the fresh air blowing in, you are pushing out the hotter air and bringing in much cooler air… Once on recirculate, you are now recirculating cooler than ambient temperature and every time it recirculates it gets cooler and cooler…If you keep it on fresh air then you will continue to try to cool off ambient temperature…
Tinted windows help to keep the cabin a little cooler, my truck with tinted windows and vent shades (rain deflectors) does get nearly as hot as my other vehicles without tinted windows and no vent shades… Both trucks have tined windows and vent shades…
