Energy Efficiency
Clean Fridge Condenser/Evaporator Coils Once Per Quarter

What Is It?

The condenser of a refrigerator or freezer is the coil on the outside of the unit; the evaporator is the coil on the inside. Coolant is circulated through the system by a compressor. In a refrigerator, coolant is chilled in a condenser, then flows to the evaporator, where air is cooled by contact with the coil. Dust and grime accumulate on the coils and reduce the efficiency of the heat transfer.

Benefits

Cleaning the coils improves the efficiency of the heat transfer and cooling process. Bacteria and grime are more likely to build up on the coils of walk-in freezers, so cleanliness is also addressed with regular cleaning.
