How to Clean Refrigerator Coils

Regular cleaning of your condenser coils is a simple yet crucial maintenance task that can significantly improve the performance and lifespan of your commercial refrigeration equipment. Over time, these coils can become coated with dust, dirt, and debris, which can hinder their ability to dissipate heat efficiently. Conveniently, you don't need to call in a professional to clean your refrigerator coils. With just a few tools and some elbow grease, this job can be performed by almost anyone.

The Best Way to Clean Refrigerator Coils

If you need a quick tutorial, check out our step-by-step video to learn how to clean your refirgerator coils. It's an easy task that only takes a few minutes to complete.

What Are Condenser Coils?

Condenser coils, also called refrigerator coils, are responsible for removing heat from the refrigerant gas, condensing it into a liquid form, and releasing it outside the unit. By effectively dissipating the heat, condenser coils ensure that the refrigeration system operates efficiently. Coils are often made of copper or aluminum due to their excellent heat transfer properties. The coils are usually arranged in a serpentine or grid pattern to maximize surface area for heat exchange.

Where Are Refrigerator Coils Located?

Most refrigeration units feature a similar design, with the condenser located on the bottom, side, rear, or top of the unit. You can identify it because it will be covered by a grill that emits hot air. To access the coils, you must use a screwdriver to remove the grill plate.

Condenser coils have a finned structure, which helps to increase the surface area available for heat transfer. The fins are thin metal pieces that run vertically along the coils, providing additional contact points for heat dissipation. The coils themselves are tubular and are connected to the refrigeration system through piping.

Why Do the Coils Need to Be Cleaned?

Over time, condenser coils can become dirty and clogged with dirt and other debris. Condensers located at the bottom of the unit are prone to collecting dust from the floor and getting splashed by mop water every time the floors are cleaned. This buildup can hinder the heat transfer process, causing the refrigeration unit to work harder to maintain the desired temperature. As a result, the unit may consume more energy and experience increased wear and tear, leading to potential breakdowns and costly repairs.

If you're troubleshooting cooling issues with your refrigeration unit, many times the culprit is a dirty and overworked condenser. Regular cleaning and maintenance of condenser coils are essential to ensure the efficient operation of commercial refrigeration units. By keeping the coils clean and free from debris, you can help optimize the heat transfer process, improve energy efficiency, and extend the lifespan of your equipment.

How to Clean Commercial Condenser Coils

To keep your refrigeration equipment running smoothly, it is recommended to clean the condenser coils at least every three to six months, depending on the environment and usage of the unit. This preventative maintenance task can be easily performed by following a few simple steps:

1. Turn Off the Power: Before starting the cleaning process, always ensure that the power to the refrigeration unit is turned off to prevent any accidents or damage.
2. Locate the Condenser Coils: The condenser coils are typically located at the back or bottom of the refrigerator or freezer. Some units may have access panels that need to be removed to reach the coils.
3. Brush Away Debris: Using a coil brush or a soft-bristled brush, gently remove any visible debris, dust, or dirt from the coils. Be careful not to bend or damage the fins of the coils during this process.
4. Vacuum the Coils: After brushing off the surface debris, use a vacuum with a soft brush attachment to further clean the coils and remove any remaining particles that may be lodged in between the fins.
5. Wipe Down the Coils: For more thorough cleaning, dampen a cloth with a mild detergent or coil cleaner and gently wipe down the coils to remove any stubborn dirt or grease buildup.
6. Reassemble and Power On: Once the coils are clean and dry, reassemble any access panels that were removed and turn the power back on to the refrigeration unit.

By incorporating regular condenser coil cleaning into your maintenance routine, you can help improve the efficiency of your commercial refrigeration equipment, reduce energy consumption, and extend the lifespan of your units. This simple maintenance task can go a long way in ensuring that your refrigeration equipment operates at its best, keeping your food products fresh and your business running smoothly.
