Clean the condenser coils

Fridges and freezers stay cold by compressing and decompressing 300-135 gas at the back of their compartments. The hot gas is sent through condenser coils out the back of the appliance where the heat can be dissipated.

For that heat to disperse as efficiently as possible, you’ll want to clean the dust and grime from the coils two or three times a year. Some say this can improve efficiency by up to 15%.

Make sure the back and sides are well ventilated

As well as keeping the coils clean, you need to make sure air can get to them easily. If there’s not great air flow, it’ll get hot behind your fridge and freezer and they’ll have to work harder to cool down.

Keep them defrosted

As the actual cooling happens outside the fridge and freezer compartments, any frost build-up inside can keep the cold out. That’s because there’s an extra thick layer for the cold to get through before it can chill your food. So make sure you defrost your appliances regularly.

Check the seals

If the door seals on your fridge and freezer are warped or damaged, they could be leaking precious cold air. Make sure you keep them clean and in good condition to have them working their best.

Keep them full

The more food you have in your fridge and freezer, the more efficient they’ll be. That’s because when they’re full of food, there’s less air to cool down and less warm air that can sneak in when you open the door.

Don’t browse your food

Unless it’s a particularly cold day and you’re trying to save on your heating bills, the inside of your fridge and freezer will be colder than your kitchen. So if you stand there with the door open, trying to decide what to eat, you’re just letting warm air in. Only open the door for the shortest time possible.
