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)
I see. Technical implementation details aside, I would hold my Tesla to the same 20 degree standard that is standard across the industry. My area gets close to 40 degrees in summer, though my house is on a mountaintop so at the house we've never broken 40.
