A correctly sized A.C. unit runs long enough to stir the air, keep the temperature in different rooms the same, and lower the humidity sufficiently without turning on and off too quickly. If it's too small, it can cause the house's temperature to rise during hot afternoons, keeping parts under constant stress and heat rather than allowing them to cool down. When oversized, houses may cool quickly but still feel chilly because they turn off before removing humidity.
