Maintaining And Caring Your Refrigeration Equipment

Refrigeration Equipment - refrigerator coils get dirty, the heat doesn't go anywhere, and it takes more energy to cool the food. Regular cleaning and upkeep of refrigerator coils is inexpensive. You can do this yourself or hire someone to come in and do it.

Create a calendar with the recommended maintenance dates for all parts and equipment, including monthly, quarterly, semi-annual and annual checks. The schedule should note:

(1) when air-conditioning-equipment air filters should be changed

(2) when exhaust- and supply-fan bearings should be lubricated

(3) when thermostats on cooking and air-conditioning equipment should be calibrated

Materials Needed

Cleaning Procedure



When needed


Sponge, cloth or paper Towel, Mild Detergent


Wash with warm water and mild detergent. Do not use abrasive or harsh cleaners. Rinse and dry.




Appliance wax, good auto wax, or stainless steel spray (Satin Shine)

For rust protection, wax painted metal surfaces at least once a year. Do not use wax on plastic parts.

Inside walls/floors/ Shelving




Sponge, soft cloth or paper towel; baking soda or mild soap Sponge, mop (for floors), or sprayer.

Wash with warm water
and a mild detergent or
two tablespoons baking soda to one quart warm water. Never use steel wool or other abrasive. Rinse and dry.

Doorliners & gaskets




Sponge, soft cloth or paper Towel and mild detergent


Wash with soap and warm water. Rinse and dry.


Condenser coil




Vacuum cleaner


Remove louvered panel. Clean dust and lint from condenser.




Broom, Dust Pan

Sweep floors daily


1. Clean and lubricate compressors according to manufacturer instructions.

2. Once a month, uncover the condenser and vacuum thoroughly. Unplug the unit carefully as to not dislodge the sensitive controls. Dirt and dust accumulations interfere with the circulation of air through the cooling coils. Check filters and replace as needed.

3. To maintain proper air circulation, never store boxes on top of the walk-in units, (especially in restaurants with low ceilings).

4. Keep the door handle, door closure kit, door hinges, sweep gasket, and door gasket free from dirt and in good repair. Check the door gaskets for splits or cracks. Poorly sealed doors will cause the units to operate inefficiently, and might also lead to expensive repairs. It is recommended that you change door gaskets every 3 to 5 years.

5. Monitor refrigeration units for excessive noise and vibration. Check for and quickly repair bent fans, loose belts, and worn bearings.

6. During extended periods of summer heat and humidity, place a small house fan on top of the unit near the condenser to enhance cooling efficiency.

7. Following manufacturer instructions, calibrate the dial thermometer twice a year.

Regularly check things such as door gaskets, hinges and catches, to minimize leaking of warm air into the unit.

Check temperatures regularly.

Allow adequate airflow around the motor and condenser fins. Clean them regularly,as built up dust acts as an insulation layer which may cause motors to overheat.
