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)

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.

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.

Generally 23-24 for winter and a couple of degrees lower for summer.

Always set to 69.

In the winter:

• 23 in the driver’s position (me)
• 25 on the passenger side with seat warmer on full (my GF).
• All back seats on both rows get 24 (my kids), as they’ve never really complained about temps.

In the summer it’s 20C across all seats.

Ergo, in general the opposite of outside.

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 🤷‍♂️

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

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.

75 in the summer
69 in the winter

Same with the home thermostat

Usually 60-65°F (15.5-18.3°C for you civilized folk). I like it chilly :)

Right now, it’s usually at 73 in the morning and 66 in the evening, medium fan speed. If I’m running the seat heater, I’ll back down the morning temp after a bit to that 66ish range.

I’m usually hot and prefer to be just ever so slightly chilly.

73 if I’m cold. 68 if I’m hot.
