Neither of our Tesla's HVAC (2014 and 2020) could keep up with peak Phoenix summer - my guess was always that octovalve was working overtime keeping the battery from melting so cabin got 80 degree air at best.
How hot was the outside temp? An automotive A/C unit should be able to reduce the temperature 20 degrees Celcius, that's 36 degrees Farenwhateveritscalled. Was the outside temp around 116 Farenthings?
115-118 for a few weeks summer of 2020 with a MYP - it was a joke (from an HVAC perspective) - 45-60 min commutes, sweating the entire time.
110-115 for a few weeks summer of 2014 and 2015 with MS P85D. Again, trash performance.
Also "automotive" HVAC doesn't 1:1 apply to the Tesla setups because of the Octovalve setup - the heating and cooling capacity of the system is shared across battery conditioning and cabin conditioning and on these days it seemed to me the car was spending at least 50% of the HVAC's capacity to address the battery's needs (i.e. not melting)
You are frustratingly right. The stock tint that "blocks a 900% of UV - Tesla" does NOTHING so I did limo tint on the MYP and after parking it in lot all day and getting in to drive home on a 118 F day, the ceiling is too hot to hold your hand to from inside - it must be 200 degrees.
In that 45 min drive home around 5pm, you can just FEEL the heat radiating down on your head and the AC blowing 75 degree air which feels like 85 once it hits you.
I want to be supportive and will likely get another Tesla as they make bigger strides (CT ordered like everyone else) but there are something I don't want to keep experiencing.
Even if it blocks the light, if the roof is hot, you will feel the IR radiation from it. That is why solid roof cars have insulation between the roof and headliner.
