Commercial refrigeration is essential for many businesses. A failing unit can lead to spoiled food and significant losses, so prompt repairs are necessary for smooth operations. If you notice the following signs, contact a professional to prevent extensive damage and keep the unit running. 

When Should You Contact a Refrigeration Technician?

1. Strange Noises & Smells

Large commercial refrigeration units naturally emit some noise. This hum comes from the compressor, which is the pump that manages the cooling process. You may also hear some gurgling noises as refrigerant circulates.

Grinding or knocking sounds could indicate that the condenser fans are broken or striking an obstruction. Loud humming means the compressor is struggling to run. This often happens when it becomes dirty, and the problem will eventually lead to a costly breakdown.

If you smell chemicals, you may have a coolant leak. The aroma is often described as musty, and your unit won’t be able to maintain cold temperatures without the substance. A technician can repair the damaged line and refill the coolant to stabilize temperatures.

2. Frost

The evaporator coil in your unit circulates warm and cool air to maintain the programmed temperature. When the component malfunctions, frost will collect inside the fridge because it can’t remove moisture.

This frost can damage food and the interior of the unit. A technician will diagnose the cause and clean or replace the affected components to eliminate the ice.

3. Fluctuating Temperatures

Fluctuating temperatures are bound to ruin food, and they can be caused by a variety of issues. The temperature sensor may be damaged or failing from age. Inconsistent temperatures also common when the compressor is damaged or dirty and doesn’t allow heat to escape.

A technician will inspect both components to see what needs to be repaired. They’ll also test the seals around the doors to ensure they’re airtight.
