Keeping your commercial refrigeration system in top condition is critical for food safety, efficiency, and long-term performance. Here are six essential maintenance steps every business should follow:
1. Clean Interior & Exterior Surfaces
Empty the unit regularly and scrub shelves, walls, and bins with warm soapy water or a refrigerator-safe cleaner. On the outside, use a soft cloth or microfiber rag with mild detergent. For stainless steel, finish with a polish for a like-new shine.
2. Maintain Condenser & Evaporator Coils
Dirty coils trap heat and strain your system. Use a coil cleaner, small brush, or compressed air every three months. Realign bent fins with a coil comb. For evaporator coils, remove grease and grime to ensure proper airflow, especially if located near cooking equipment.
3. Replace or Clean Air Filters
Clogged filters block airflow and reduce cooling efficiency. Inspect filters frequently, vacuum out dust and grease, and replace them if damaged or excessively dirty.
4. Clean Drain Pans & Tubes
Sludge and food debris can clog drain lines, leading to overflow or freezing. Clean pans and tubes monthly with warm, soapy water to prevent buildup and contamination.
5. Inspect Door Gaskets
Worn or cracked gaskets cause cold-air leaks, food spoilage, and higher energy bills. Clean them monthly and replace immediately if damaged.
6. Remove Moisture & Keep Unit Dry
Check for condensation or spills behind shelves and wipe them weekly. Excess moisture can freeze, overwork the compressor, and shorten equipment life.
By following these six steps consistently, you’ll extend your system’s lifespan, improve energy efficiency, and protect your business from costly breakdowns.
