The Hidden Energy Hog in Your Kitchen

Every 6 months Easy 15 minutes

If your fridge has been running a little louder—or your energy bill has been creeping up—it might be time to check something most people forget: the refrigerator coils. These coils, located either behind or beneath the unit, release heat as your fridge works to keep things cold.

When dust, pet hair, and kitchen debris build up on the coils, your fridge has to work much harder to maintain temperature. This not only shortens its lifespan but can increase energy use by up to 30%.

How Often Should You Clean Them?

Standard: Every 6 months is ideal
High-traffic kitchens or pet owners: Every 3–4 months

Quick Step-by-Step

  1. Unplug the refrigerator
  2. Locate the coils (check your manual)
  3. Use a coil brush or vacuum with narrow nozzle
  4. Gently remove dust and debris
  5. Plug back in and enjoy the quieter hum

The Payoff

  • 💰 Lower utility bills
  • 🔧 Longer-lasting fridge
  • ✅ Fewer surprise breakdowns

It's one of the easiest DIY maintenance tasks you can do.

Step-by-Step Plan

  1. Unplug the refrigerator

    Disconnect power to stay safe while working near the coils.

  2. Locate the coils

    They are behind a rear panel or under a toe-kick; consult your manual.

  3. Brush or vacuum

    Use a coil brush or vacuum with a narrow nozzle to loosen and remove dust.

  4. Clear debris

    Work gently to avoid bending fins; wipe surrounding area.

  5. Restore power

    Plug the fridge back in and confirm normal operation.

Tools Needed

  • Vacuum with crevice tool
  • Coil cleaning brush
  • Flashlight (optional)

Safety Notes

  • Always unplug before cleaning.
  • Avoid bending the coil fins.
  • Wear a dust mask if you’re sensitive to dust.
