Make sure your fridge is level.

Here's a quick tip that can save significant amounts of energy. When you open your fridge door, does it stay open by itself? Do you often have a difficult time closing that fridge door?

If your answer is "yes" then you need to see if your fridge is actually level. If your fridge is level then we can really help you. If your fridge is not level than take the time to level it. Once it's level then doors will close much easier and will stay closed. This will save energy because the cold air has a greater chance of staying trapped inside your fridge because your door will not have a tendency to swing open.
