Choose a dishwasher with sturdy compression springs in the door. Also look for tough, lightweight nylon or graphite racks with cushioned tips that protect glassware and cookware. Weimer recommends choosing a model with a rack design that provides the largest, most flexible interior space and is configured for your belongings, including odd-shaped pieces.

The EnergyGuide label on new refrigerators will tell you how much electricity in kilowatt-hours (kWh) a particular model uses in one year. The smaller the number, the less energy the refrigerator uses and the less it will cost you to operate. In addition to the EnergyGuide label, don't forget to look for the Energy Star label. A new refrigerator with an Energy Star label will save you between $35 and $70 a year compared to the models designed 15 years ago. This adds up to between $525 and $1,050 during the average 15-year life of the unit.

Shelves or cabinets above the cook top can hold foods that aren't affected by warmth, such as pasta, rice, and cereal. A shelf just below these cabinets but above the cook top can transform the space into a cooking workshop, providing a handy resting place for timers, spices, cooking supplies and implements.
