Most car ac systems are either on, or off. They don’t have variable compressor speeds. They cool at maximum until they reach the temp you set then they switch off. If the temp rises again then they switch back on.
A non EV cars heat is provided by the coolant that circulates through the motor. Nothing you can do will make the heater heat up faster.













Yes that is true, I assumed everyone knew that 90% of engine wear occurs during the warm up period so you’d be foolish to ever run the car harder than needed in that period.
I was referring to turning up the heat to full or anything you can do in the cab as the poster seemed to think he could get more heat from the old analog systems faster than a standard climate control system.
