Right now, the outside temperature oscillating between 5°C (41°F) and 12°C (54°F) where I live, I set it at 18°C (64°F) because I wear a big wool sweater and don’t want to completely undress/dress when going in and out of the car. I live in France in the countryside, so cities a pretty walkable (so you have to dress accordingly) and our cars small (compared to American standards). I drive a Seat Ibiza which is a pretty standard sized car here :

293 kelvin

I’m lazy and just set it to the max/min possible depending on if I’m cold or hot. This probably isn’t good. Does it feel good in the moment? Yeah.

21 degrees Celcius.

Always set to 69.

Opposite of what one might think. In the winter I keep it at 17C or 18C because I am going to be getting out into even cooler temps and I am often wearing a jacket. In the summer I keep it at least 22C and up to 25C depending on outside temp so I don’t feel like I’m going from the fridge into the oven when I get out of my car. I haven’t found that having the passenger seat set at a different temp works so I keep the whole car at the same temp. However I also have heating and cooling seats and heated steering wheel which I also use to offset the outside temp.

Base: 23°C (because fuel vehicle. It’s waste heat, might add well make it t-shirt weather inside)

Was I cold before getting in? +1°C Warm? -3°C

Am I dressed for cold weather or is it warm outside and I don’t want it to heat up the air from outside further? -5°C

Is sun on my side of the car? -1°C in winter, -6°C in summer (52 degrees north)

Am I arriving within a few minutes? AC off

Is the stuff around me radiating heat or cold? - 2 / +2 °C because the air temperature is only one factor in how warm you feel (imagine a hot lamp vs. cloudless night sky above you)

Hah, joke’s on you! Mine still has a dial with no numeric measure whatsoever

I maintain a fleet of cars. When I do my weekly inspections, I set every single temperature on the HVAC system to 69f. It’s been several years, my boss hasn’t said anything.

22° C

I like it freezing so i only use it half of the year. Right now its cold enough outside.

The only exception is for clearing the windshield.

22 when it cold, max cool (18 and max fan speed) this time of the year in the afternoons until the air temp comes down, then just reduce the fan speed

21.5C in the winter, 19.5C in the summer/for drives over 1 hour long.

I live in tropical climate where the usual temperature is around 29° and humidity is around 80% or more.

I set the AC to 22° all the time. What’s more important though, and something I didn’t realise before moving to this climate, is that you want to have the recirculation on at all times. Otherwise the air in the car is too hot and humid even if you set the temperature lower.

I like 70. Maybe 68 if it’s a super hot day and I want it to cool down quicker.

I never use heat. It doesn’t get cold enough here to need it. At most I’ll turn the defogger on; but leave it on cool 🤷‍♂️
