Types of refrigerators

Today's refrigerators are available in several options: side-by-side models, top-freezer or bottom-freezer units (one with a freezer on top or along the bottom), or French-door models (a side-by-side refrigerator on top, single-door freezer on bottom).

Top-freezer refrigerators, the least expensive option, are also the least repair-prone products. However, most people use the refrigerator more than the freezer, and the bottom half of a top-freezer's refrigerator requires bending over to access. Most top-freezer models have limited storage options -- especially in the freezer compartment, which usually has only a single shelf -- so organization can be tricky as well.

Side-by-side refrigerators cost more than top-freezer refrigerators and less than French-door refrigerators. Most include features such as through-the-door ice and water dispensers. If you have a narrow or galley kitchen, side-by-side refrigerators need less door clearance. However, reviews say side-by-side refrigerators also have some disadvantages. Aside from higher cost -- sometimes twice that of comparable top-freezer models -- their narrow shelves don't generally accommodate common items like wide pans, and repair-prone through-the-door dispensers can be problematic. Most side-by-side refrigerators are less energy efficient than top freezers, even though many are Energy Star-compliant.

Bottom-freezer refrigerators are a little more expensive than top-freezer refrigerators and generally more convenient to use because the more frequently accessed refrigerator is on top. They don't have through-the-door water or ice dispensers, but some have internal ice makers. Bottom-freezer fridges are becoming uncommon, however, as French-door refrigerators fall in price and rise in popularity.

French-door refrigerators pair a side-by-side refrigerator on top with a bottom full-width freezer. These models sometimes have a through-the-door ice and water dispenser. French-door refrigerators let you open just one side of the refrigerator, so less cool air escapes. At the same time, you'll still be able to fit in wider items such as sheet cakes and pizza boxes. Owners posting to review sites also love ice and water dispensers, since you don't need to open the door for ice cubes. Most French-door refrigerators range in size from 20 to 26 cubic feet and come with lots of convenience features such as adjustable shelves and water filters for the ice maker. They tend to cost a little more than side-by-side refrigerators. Many models are Energy Star-rated.

Overall, when it comes to refrigerators, performance is almost a non-issue. Basic cooling technology hasn't changed in decades, and any refrigerator will keep food cool if it's functioning properly. Cold spots, which can lead to ice crystals in food stored near the back of the refrigerator, are rarely seen these days except in very inexpensive builder's grade refrigerators. Still, side-by-side and French-door refrigerators generally regulate temperature a little better than top-freezer refrigerators. Instead, the only major differences among refrigerators are in reliability, door style, noise level, energy efficiency and extra features that make organization and cleaning easier. Here's what experts say to consider when buying a refrigerator:

  • Get the largest unit that will comfortably fit your space. Shop with a tape measure and consider height, width, depth and door-swing clearance. Keep in mind, though, that larger refrigerators typically use more energy and cost more.
  • Consider buying an Energy Star-rated refrigerator. Not only will you save money on your electricity bill, you may be eligible for a rebate from your city or electricity provider.
  • Look for a convenient interior layout. A refrigerator should have the ability to store wide and/or tall items and should have no hard-to-reach or hidden spots.
  • Shelves should be sturdy, flexible and easy to clean. Glass is generally better. Some glass shelves have a raised, sealed rim to stop spills from dripping over. Adjustable shelves are a plus: Some models have half-shelves that can be matched up for a wide, flat surface or adjusted separately for odd-height items. Other models have elevator shelves that crank up or down. A few models also include a wine rack.
  • Look for easy-to-reach temperature and humidity controls. Controls should be up front rather than on the back inside wall, where you may have to empty a shelf to adjust them. Nice extras include humidity-controlled vegetable crispers and temperature-controlled meat and deli drawers.
  • The interior should be well lit. Most models have a light inside the refrigerator compartment; some have additional lights in the freezer or produce bins.
  • The refrigerator should be relatively quiet. Look for insulation to help dampen the sound of the compressor.
  • Electronic touchpads are easier to use. Many models now have digital controls and displays that show the actual temperature of the various areas and compartments of the refrigerator. However, electronic controls and thermometers are more likely to fail. It's a good idea to double-check your refrigerator and freezer's temperature periodically with a conventional thermometer.
