How to Clean Refrigerator Coils in a Small Apartment
15.08.2026
To clean your refrigerator coils, unplug the fridge, find the coils (behind the toe-grille at the bottom or on the back), and vacuum the dust off with a brush attachment. Loosen packed grime with a slim coil brush, vacuum again, then plug back in. In a small NYC kitchen, plan for 15 minutes and do this every 6 months.
What you'll need
- A vacuum with a crevice or dusting-brush attachment
- A refrigerator coil brush (long, narrow, flexible) — or a bottle brush in a pinch
- A flashlight or your phone's light
- A flathead screwdriver (some toe-grilles clip off, others unscrew)
- A damp microfiber cloth
- Knee pad or folded towel (you'll be on the floor)
Step by step
- Unplug the fridge. Reach behind and pull the plug, or trip the breaker. Don't skip this — you're working near a compressor fan.
- Find the coils. On most modern apartment refrigerators they sit behind the kick-plate (toe-grille) at the bottom front. On older or built-in units they run up the back, which means pulling the fridge out from the wall.
- Remove the grille. Toe-grilles usually pop off with a firm pull at the bottom corners; a few are held by screws. Set it aside.
- Vacuum the loose dust. Use the brush attachment to lift the visible gray fuzz off the coils and the floor of the compartment.
- Work the coil brush in. Slide the narrow brush between and along the coil fins, then pull it back toward you. Dust that's packed tight won't vacuum out until you loosen it first.
- Vacuum again. Clear everything the brush knocked free, including the fan blades and the drip pan area if you can reach them.
- Wipe the grille and floor. Run a damp microfiber over the toe-grille and the floor underneath before reassembling — this is prime spot for grease-dust buildup in a galley kitchen.
- Reattach and plug in. Snap or screw the grille back, slide the fridge into place, and restore power. Give it a few hours to return to temperature.
What NOT to do
- Don't use water or spray cleaner directly on the coils. These are electrical components — a damp cloth is for the grille and floor only, never the coils or fan.
- Don't yank the fridge across the floor. In an apartment, dragging it can scratch or gouge hardwood, tile grout, or vinyl. Lift-and-walk it, or slide a towel underneath first.
- Don't jam a metal tool into the fins. Coil fins bend easily, and a screwdriver can puncture the tubing. Use a brush with soft bristles.
- Don't forget the wall gap. If you pull the fridge out, check the power cord isn't pinched against a steam radiator or hot pipe when you push it back.
- Don't over-clean. Twice a year is plenty for most units; monthly scrubbing accomplishes nothing and risks bending fins.
When to call a pro
If your coils are behind the fridge and it's a heavy built-in, wedged into a tight alcove, or sitting on delicate flooring, moving it alone can damage the unit or the floor — and a coil that's crusted with kitchen grease often needs the whole area degreased, not just dusted. If cleaning behind and under the fridge is part of a bigger kitchen reset you'd rather hand off, book apartment cleaning with CleanWhale and we'll handle the reach-behind spots along with the rest.
FAQ
How often should I clean refrigerator coils?
Every six months is a good rule for most NYC apartments. If you have a shedding pet or a small kitchen where the fridge sits close to the stove, dust and grease build faster, so check every three to four months.
What happens if I never clean the coils?
Dust-coated coils can't release heat efficiently, so the compressor runs longer and harder. Over time that can mean a warmer fridge, higher electric bills, and more wear on the motor.
My fridge coils are on the back and it won't move — what do I do?
If it's a rental with a built-in or a fridge in a tight cabinet cutout, don't force it. Vacuum whatever you can reach from the sides and top with a crevice tool, and ask your landlord or a pro to pull it out for a full cleaning.
Can I use compressed air instead of a vacuum?
You can, but in a small apartment it just blows dust into the air and onto nearby surfaces. If you do, hold the vacuum nozzle right next to the coils to catch what the air dislodges, and open a window if yours opens.
