MAC computations estimate the hourly, daily, weekly and monthly costs to operate an appliance. The results reflect controlled laboratory conditions and may vary in actual use of the appliance. Factors that affect the operation and efficiency of appliances (e.g., age of unit, wear and tear of parts, wrong operation, room temperature, mishandling, etc.) can bring different results to different customers.
