What will be monthly power bill if i buy a 1.5tr blue star split

Don't buy a refrigerator bigger than you need. One rule is to choose a model that has 10 cubic feet of food storage for a family of two and then add an extra cubic foot for each additional person in the household.Side-by-side refrigerator/freezers use more energy than units with the freezer above or below the fresh food compartment.Look for the Energy Star label. It is a quick and easy way to avoid paying for a mistake with each month's electricity bill.
