Supermarket Rack System Maintenance: What to Check Quarterly

Supermarket refrigeration doesn’t fail overnight, it drifts. Pressures slip, subcooling fades, coils frost unevenly, and by the time the alarm lights up, efficiency has been leaking away for months. At Tracey Refrigeration, we treat rack systems like the living infrastructure of your store, something that needs rhythm, not rescue. From subcooling stability to airflow precision and electrical hygiene, we keep the invisible parts steady so your aisles stay calm, compliant, and cold. Whether you manage one location or a network across the GTA, knowing when and why to bring in specialists isn’t about surrender, it’s about staying ahead of downtime.
