Heat raises the workload
High outdoor and kitchen temperatures make it harder for commercial refrigeration systems to reject heat. Equipment that was barely keeping up in mild weather may show temperature swings or longer run times during a heat wave.
Protect airflow around equipment
Keep cartons, supplies, and clutter away from condenser areas, vents, and mechanical spaces. Good airflow cannot fix a failing system, but restricted airflow can make existing problems worse.
Check doors and loading habits
Hot, humid air enters every time a door is opened. Train staff to close doors fully, avoid propping them open, keep gaskets clean and intact, and avoid blocking interior air paths with product.
Watch temperatures more closely
Review temperature logs more often during extreme heat and investigate upward trends early. Confirm questionable readings with a reliable thermometer and follow your food-safety procedures if required temperatures are not maintained.
Schedule preventive service
Before the hottest part of the season, schedule a qualified maintenance visit based on manufacturer guidance and your operating conditions. Ask the provider to inspect performance, airflow, coil condition, drains, door seals, and controls as appropriate.
Plan for an outage
Keep a current list of emergency repair contacts, equipment model information, backup storage options, and staff responsibilities. An emergency plan helps reduce decision time when a unit fails during a busy period.
