In this heat?

If anyone has a meat thermometer or similar thermometer, would you mind going to your car, putting the AC on max cold and fresh air and measuring the vent air temperature in this weather?
Mine isn't blowing 'ice cold' like normal, its 12 degrees C, and I can't work out if its a potential performance issue I need to investigate, or just that it's so hot the system physically can't chill the incoming air any lower.

Make/model would also be interesting!

Not my car but my partners 2019 VW T-Roc - had a regas yesterday at work and i measured it gradually falling to 9 degrees. Which is nice and cold...but to compare...the day before we had a Hymer motorhome which went down to 4.6!

In our experience, normal is probaly around the 6-10 area (after a successful regas)

But we do sometimes see higher figures than that.

4 degrees, Outside temp is 31, Tesla model 3.

12 degrees is not cool enough, I’ve seen 4-6 on most of my previous cars

Is it chilling "incoming air" or is it recirculating interior air? Obviously if the former, the temperature it can achieve will depend directly on the external temperature, if the latter the temperature of the incoming air will drop over time in a feedback loop.

Meat thermometer?

Don’t be barbecuing in your car, do it in the boot.

Yes this is cooling incoming air, not recirc. I thought that would be the only useful way to compare seeing as we all will have roughly the same outside air temp right now.

An AC system can only reduce the ambient temperature by so much, it will not chill to 4c regardless. A drop of 15c is fairly typical of most automotive set ups.
