Ovens - When buying 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. An important factor to consider when buying an oven is the type of cleaning process it uses. Standard ovens will have to be cleaned manually, but there are now self-cleaning ovens with programmable settings, which use high temperatures to clean off any residue. You can also get continuous cleaning ovens that absorb or burn off splatters, making it even more convenient.

Refrigerators - As a rule of thumb, plan on purchasing 8-10 cubic feet of space for a family of two, then add an additional 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. The new stainless-steel models can improve energy efficiency during drying cycles and allows for higher water temperatures as well.

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. If you can, try to find one that has a low sone rating. The lower the sone number is, the quieter your range hood.

Garbage Disposal Systems - There are a few things to consider when you want to buy a garbage disposal. 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 - Check the energy tag attached to the unit and consider the energy 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. Do you need to cool the whole room? Does the weather change a lot where I'm located? The answers will help you find a suitable model that will fit 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 - Again, energy efficiency is the important factor here. 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. 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 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. They are powered by either gas or electricity and turn off when not being used. However, they have trouble supplying large amounts of hot water at any one time.
