Abstract: A method and an apparatus are provided for variably controlling the temperature at which the clutch of an air conditioner compressor is engaged and disengaged. The temperature at which the compressor clutch is engaged and disengaged is based on an average minimum temperature at the evaporator over a clutch cycle, wherein the clutch disengage temperature is increased if the average minimum temperature is below a first predetermined temperature and is decreased if the average minimum temperature is above a second predetermined temperature, thus maintaining the average minimum temperature within a temperature range. Further, the clutch disengage temperature is adjusted based on user operated air conditioner control settings. The clutch disengage temperature is adjusted to a higher temperature if a low blower speed is selected by the user and is adjusted to a lower temperature if a high blower speed is selected.
