FAQ Section

Q: How do I determine the right size refrigerator for my restaurant?

A: Calculate based on your daily meal volume and menu complexity. Quick-service restaurants (100-200 meals) need 20-40 cubic feet, while full-service operations (400+ meals) require 80+ cubic feet. Consider menu variety, seasonal fluctuations, and future growth plans.

Q: What's the difference between reach-in and walk-in refrigeration?

A: Reach-in units are smaller (20-80 cu ft) and designed for frequent access with swing doors. Walk-in units are room-sized (200+ cu ft) for bulk storage with minimal access frequency. Choose based on your storage volume and access patterns.

Q: How often should commercial refrigeration be serviced?

A: Schedule professional servicing every 6 months for optimal performance. Daily cleaning, weekly deep cleaning, and monthly professional inspections help prevent costly breakdowns and maintain food safety.

Q: What are the most energy-efficient refrigeration options?

A: Look for ENERGY STAR certified units with LED lighting, high-efficiency compressors, and improved insulation. These can save 20-40% on energy costs compared to standard models, with payback periods of 2-4 years.

Q: Can I install commercial refrigeration myself?

A: Professional installation is strongly recommended. Improper installation can void warranties, create safety hazards, and reduce equipment lifespan. Licensed technicians ensure proper electrical connections, refrigerant charging, and performance optimization.
