Ovens - When shopping for an oven, your first decision should be whether you want a gas oven or an electric. This decision can be made according to your cooking preferences. Also, consider the type of cleaning process it uses. Standard cleaning ovens require you to clean it yourself. Self-cleaning ovens often have programmable cleaning settings that use high temperatures to clean residue from the oven. Continuous cleaning ovens have special finishes that absorb or burn off splatters from the oven.

Refrigerators - A rule of thumb when buying a refrigerator is that you need to consider the number of people in your household to determine the capacity you need. For example, a family of two needs at least 8 to 10 cubic feet, then add another cubic foot of space for each family member. Remember that refrigerators with freezers on top are generally more energy-efficient than those with side-freezers.

Dishwashers - Always find out the amount of water a dishwasher uses for every different cycle. Features that reduce water usage are very important. Newer, more expensive stainless steel models enhance efficiency during drying cycles and can tolerate higher water temperatures.

Ventilation Hoods - The fan will be the most important factor here. Axial fans are inexpensive but not as powerful as centrifugal fans. Try to find hoods that have a tempered glass light lens. These are more durable than the plastic lens, which yellow and crack, and they last longer. If you can, try to find one that has a low sone rating. Sones measure the noise level created by air-moving appliances, and the lower the sone number, the quieter it is.

Garbage Disposal Systems - When shopping for a garbage disposal, there are several things to consider in order to arrive at the best disposal to fit your needs. Think of how many meals per week are prepared in your kitchen, how often you entertain, and the importance of quiet operation and long product life. You also must know if you are hooked up to a septic system or regular water system.

Air Conditioners - When looking for a powerful air conditioner, check out the yellow energy tag (represented as Energy Efficiency Ratio or EER) and consider its efficiency. The Energy Efficiency Ratio, or EER, ranges from 8 to 12, so the higher the EER number, the better the efficiency. After this, you also need to consider the space of the room you'll be putting the air conditioner in, as well as your budget. How big is the room? Is it important that the whole room be cooled? Is there variable weather? Do I move from room to room a lot? The answers to these questions will help you find the suitable model for your needs. Try to match the unit's cooling capacity with the size of the room. Follow the Dept. of Energy's formula, which is to multiply the room's square feet of space by 20.

Water Heaters - Look for hot water heaters that are energy efficient. There is an EnergyGuide%u2122 label you can read to determine the estimated energy consumption of a particular unit and its estimated annual operating costs. Using these information, you can compare models and see which ones are better at energy saving. Tank size or capacity refers to the amount of water, in gallons, that the water heater will hold. The more gallons you need per hour, the larger the tank must be. Of course there are also tank-less systems which heat water as you need it. Tankless water systems are powered by either electricity or gas and turn off when not in use. However, they cannot be expected to supply you with large amounts of hot water at any given time.
