One reason an air conditioner runs constantly is that the thermostat is set too low for the outside temperature. An air conditioner can only effectively cool outside air by 20 to 30 degrees, so when the outside temperature is over 100 degrees, an air conditioner will run constantly if it is set to 65 degrees.
