Introduction
Ice build-up in a commercial refrigerator can lead to various operational problems, including reduced efficiency, higher energy costs, and potential damage to stored products. Business owners in Calgary who rely on commercial refrigeration must ensure their systems remain in top condition to avoid these issues.
At Freedom Appliances – Commercial Refrigeration Services in Calgary, we understand the importance of maintaining a fully functional refrigeration system. Ice accumulation can strain the compressor, clog airflow, and even cause long-term damage. Preventing this problem requires proactive measures and regular maintenance.
In this guide, we’ll explore the key reasons behind ice formation in commercial refrigerators and provide actionable steps to prevent it.
Understanding the Causes of Ice Build-Up
Before addressing solutions, it’s important to understand what causes ice accumulation in your commercial refrigerator. Here are some of the most common factors:
1. Faulty Door Seals
When the door seals are damaged or worn out, warm air enters the refrigerator, leading to excessive condensation, which then freezes.
2. Improper Air Circulation
Blocked air vents and improper storage can restrict airflow, causing uneven cooling and excessive ice formation in certain areas.
3. Frequent Door Openings
Opening the refrigerator door too frequently or leaving it open for extended periods introduces humidity, which eventually turns into ice.
4. Malfunctioning Defrost System
If the automatic defrost system fails, ice will continue to accumulate without melting properly. This is one of the most common issues in commercial refrigerators.
5. Dirty or Clogged Evaporator Coils
Dust, dirt, and grease buildup on evaporator coils reduce cooling efficiency and contribute to ice formation.
6. Incorrect Temperature Settings
Setting the refrigerator temperature too low can cause excessive frost and ice build-up.
How to Prevent Ice Build-Up in Your Commercial Refrigerator
1. Inspect and Replace Door Seals Regularly
Damaged or worn-out door seals allow warm air to enter the unit, leading to condensation and ice build-up. Conduct regular inspections to check for cracks, gaps, or loosened seals. If you notice any issues, replace them immediately.
2. Optimize Airflow Inside the Refrigerator
Proper air circulation is essential to prevent ice build-up. Follow these best practices:
- Avoid overloading shelves, as overcrowding blocks airflow.
- Keep vents clear and unobstructed.
- Regularly reorganize stock to ensure even cooling distribution.
3. Limit Door Openings and Close Doors Properly
Minimize how often the refrigerator door is opened. When retrieving or storing items, do so quickly to prevent warm air from entering. Train employees to ensure doors are always properly closed.
4. Monitor and Maintain the Defrost System
Commercial refrigerators typically have an automatic defrost cycle. However, if ice continues to build up, the system may not be functioning correctly. Conduct regular maintenance checks and schedule professional servicing when necessary.

5. Clean the Evaporator Coils
Dirty evaporator coils make it harder for your refrigerator to maintain optimal cooling. Cleaning them regularly will:
- Improve efficiency
- Reduce ice build-up
- Extend the life of your refrigeration unit
Use a manufacturer-recommended coil cleaner and soft brush to remove dust and grease. For professional maintenance, consider commercial freezer repair in Calgary.
6. Check and Adjust Temperature Settings
Setting the refrigerator to an excessively low temperature can lead to frost and ice accumulation. Follow the manufacturer’s recommendations for optimal cooling temperatures. Generally, commercial refrigerators should be set between 34°F and 40°F (1°C – 4°C).
7. Ensure Proper Drainage
Blocked drain lines can cause water to accumulate and freeze. Regularly inspect and clean the drain lines to prevent clogging. If you notice water pooling at the bottom of the refrigerator, it may be a sign that the drain is blocked.
8. Schedule Routine Maintenance
Preventative maintenance is the best way to keep your commercial refrigerator running efficiently. A professional technician can identify and resolve minor issues before they escalate into costly repairs.

Frequently Asked Questions (FAQs)
1. Why does my commercial refrigerator keep forming ice on the back wall?
Ice build-up on the back wall is usually caused by poor airflow, a malfunctioning defrost system, or a temperature setting that is too low. Ensure proper ventilation, clean the evaporator coils, and check the defrost cycle.
2. How often should I clean my commercial refrigerator’s evaporator coils?
It is recommended to clean evaporator coils at least every six months to prevent dust, grease, and dirt accumulation, which can cause ice formation and reduced cooling efficiency.
3. What is the ideal temperature setting to prevent ice build-up in a commercial refrigerator?
The ideal temperature range for commercial refrigerators is between 34°F and 40°F (1°C – 4°C). Setting the temperature too low can cause excessive frost and ice accumulation.
4. Can a faulty door gasket cause ice build-up?
Yes. A faulty door gasket allows warm air to enter, leading to condensation that eventually freezes. Regularly inspect and replace door seals to maintain optimal performance.
5. How can I prevent my drain line from freezing?
To prevent drain line freezing:
- Regularly check for blockages.
- Clean the drain with warm water and a mild cleaning solution.
- Ensure the refrigerator is not set at excessively low temperatures.
Conclusion
Preventing ice build-up in your commercial refrigerator is crucial for maintaining efficiency, reducing energy costs, and prolonging the life of your unit. By following these preventive measures—such as maintaining door seals, optimizing airflow, and scheduling regular maintenance—you can keep your refrigeration system running smoothly.
