Fridges are measured in litres (L), and range in size from 850L to less than 170L. For an average household of two people, a storage capacity of about 300L should be enough. Don't forget to measure the available space in your kitchen before you choose your fridge size.
Frost-free fridges take away the hassle of removing ice build-up by using a fan to circulate dry, cold air throughout the freezer compartment.
Make sure there are easy fixes for glass or plastic drawers and shelves, in case of any breakage or cracking.
Transporting a fridge is hard work, so it's usually worth getting someone else to do the heavy lifting for you. Ask the store about their delivery fees.
Some fridges have additional features such as water and ice dispensers that may need to be installed by a plumber—which could be costly. Find out whether specialist installation is required.

In most fridges, operating the thermostat will let you adjust the temperature to suit your groceries. Some newer models have moved from temperature control dials to digital controls, and some side-by-side models even include drawers that can be controlled separately.
Find out how much noise you can expect from internal fans, motors, automatic timers, and water and ice dispensing units before you make your purchase.
