As the temperature rises outside the unit there comes a point where the heat flow into the unit exactly matches the 100% duty cycle capacity of the AC unit. At that point no more cooling is available. The heat that flows in exactly equals the heat being removed by the AC. If you turn the thermostat down the inside temperature will NOT go down. No more cooling capacity is available. If you turn the thermostat up beyond this equilibrium temperature, the inside temperature will go up and the duty cycle will go below 100% to match the heat load required by your setting.At any stabile interior temperature, heat flow in matches heat flow out.An increase in outside temperature will cause more heat to flow into the unit while the AC can not remove this additional increment of heat flow. The temperature will rise to the point where the difference between outside and inside is reduced and therefor heat flow into the unit is reduced to the maximum capacity of the AC. A new higher temperature equilibrium is reached. Heat flow in now matches heat flow out.It's physics. The laws of nature, unlike the laws of man, can not be disobeyed.Energy can not be either created nor destroyed (by normal chemical, mechanical means. nuclear reactions can create and destroy energy.)Heat flows from the hotter to the cooler. (Or if you are a physicist, cold flows from the colder to the hotter)The universe always becomes more random (Entropy increases)
