Ovens - Before buying an oven, first you have to ask yourself whether you need a gas oven or electric oven. This decision can be made according to your cooking preferences. An important factor to consider when buying an oven is 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. You can also get continuous cleaning ovens that absorb or burn off splatters, making it even more convenient.

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. Refrigerators with freezers on the top are more energy efficient than models with side freezers.

Dishwashers - When choosing a dishwasher, you should find out how many gallons of water it uses during different cycles. 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. Also, tempered glass light lenses in a ventilation hood is essential. They are tougher than plastic lenses, so they will last longer. You should also consider buying one with a low sone number. The lower the sone number is, the quieter your range hood.

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. You need to take into account the number of meals that are prepared in your kitchen per week, how often you entertain, and the amount of noise it makes, as well as a long product life. Find out also if your kitchen is hooked up to a septic or water system.

Air Conditioners - Check the energy tag attached to the unit and consider the energy efficiency. The EER numbers range from a minimum of eight to a maximum of 12. You'll want to look for high EER numbers. 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. The EnergyGuide label gives you two important pieces of information when you're comparing different brands and models: estimated energy consumption and estimated yearly operating costs. Use this information to determine which models are the most energy efficient. As for tank size, it refers to the number of gallons of water that the water heater can hold. The more gallons of hot water you need per hour, the larger the water tank must be to accommodate the need. Of course there are also tank-less systems which heat water as you need it. They are powered by either gas or electricity and turn off when not being used. However, they cannot be expected to supply you with large amounts of hot water at any given time.
