HVAC industry is such a huge market primed to be disrupted. The way they wanted to "size" your room properly is really used to calculate cooling/heating capacity to achieve a comfortable relative humidity. But back in the days they didn't have DC inverter, units were either on 100% full power or shut off at 0%. Nowadays with linear inverter units cooling/heating can be ramped up and down, but we also have a lot more requirements now like greenhouse potential etc. Ignoring all that, it is in theory possible with 3rd party sensors + algorithm to coordinate all assets to achieve a satisfying outcome. Chug in vent control then you'd have a pretty decent solution. So if you only have AC units, it'd cool from one end with shade and fan the hot end. If you have humidifier units, then it can coerce air to be dried first before being conditioned etc. Just by turning on/off vents and units and learning from sensor data.
