How to Keep Your Fridge Running Efficiently in a Hot Sydney Summer
During a Sydney summer, your fridge works much harder than usual to maintain temperature. This can push electricity bills up and in extreme cases cause the fridge to struggle to stay cold. Here are the best tips to help your fridge perform at its best when it matters most.
1. Keep It Away from Heat Sources
Your fridge should not be positioned:
- In direct sunlight from a window
- Next to the oven or cooktop
- Near a dishwasher exhaust vent
Every degree of ambient heat around the fridge forces the compressor to work harder. If your fridge is in direct afternoon sun, consider a shade curtain or repositioning it if possible.
2. Leave Proper Clearance Around It
Your fridge releases heat through its condenser coils (at the back or bottom). It needs airflow to dissipate that heat. Make sure there's at least:
- 2–5 cm on each side
- 5 cm at the back
- Some clearance above (10+ cm for top-vent models)
3. Keep the Door Seals Clean and Intact
A leaking door seal lets warm air in, forcing the compressor to run constantly. Check the seals monthly in summer using the paper test (see our separate guide) and clean them with a damp cloth and mild soap.
4. Don't Overfill or Underfill It
A fridge that's too full restricts air circulation inside, creating warm spots. A fridge that's too empty doesn't have enough thermal mass to maintain temperature when you open the door. Aim for about 75% full.
5. Let Hot Food Cool Before Storing
Putting hot or warm food directly into the fridge forces the compressor to work hard to bring it down to temperature. Let dishes cool to room temperature before refrigerating (don't leave perishables out for more than 2 hours).
6. Clean the Condenser Coils
Dusty condenser coils are significantly less efficient at releasing heat. Once or twice a year (or more often if you have pets), pull the fridge out and vacuum the coils at the back or bottom with a soft brush attachment.
7. Set the Right Temperature
The ideal fridge temperature is 3–4°C. Colder than necessary wastes electricity without benefiting food safety. Most digital fridges let you set an exact temperature; older dial models should be set to the middle of the range.
