Except when the car has been sitting in the sun all day and the interior temp is 120+.Take it from an AC pro - really, I don't mean ACME Plumbing and Air tech, I mean a civic engineer building 25 story buildings - unless you need outside air for some reason, there's no reason not to have it set on recirculate. Why introduce hot outside air in to you system?
Thanks, as a octogenarian retired Electrical Engineer (Computers) I totally agree. It's simple thermodynamics...Take it from an AC pro - really, I don't mean ACME Plumbing and Air tech, I mean a civic engineer building 25 story buildings - unless you need outside air for some reason, there's no reason not to have it set on recirculate.

I live in sunny southern New Mexico (Las Cruces), and tempertures typlically run between 100 and 115 with very low humity, durning my recent trip to Katy, Texas... basically Houston, the tempertures were in the high nineties and the humity was 90%+... my 2019 CX-5 Grand Touring was cool and comfortabe and with the auto sense 'on' the fan speed went to high when we first started the car.I'm a bit disappointed with the aircon cooling [and heating] on a 2021 CX-5 Sig due to it's lack of oomph - was also hoping setting it to 'auto' would be sufficient, but I find I have to tweak it. In the recent hot weather, it seems to just blow out the centre vents [reasonable strong blow but not that cold even after many minutes] - reducing the temp setting just increased the fan speed (maybe the fan should get slower to reduce the volume of air the aircon has to cool & hence reduce the temp more?). Even after 15+ mins the fan speed will have reduced slightly but still set only to centre vents - I usually manually moved some air to feet vents (which is also quieter) but this then switched off auto
Is there any way to see what the car senses the inside cabin temp is i.e. what the system then uses to adjust the setting?
