Daily checks
- Room temperature and set-point matching the required range.
- Condensing unit noise and vibration — anything unusual is a warning.
- Door seals, strip curtains and self-closer working correctly.
- No frost or water ponding on the floor.
Weekly checks
- Clean the condenser coil surface — dust and cotton fluff reduce heat rejection sharply.
- Evaporator fan operation and defrost cycle behaviour.
- Drain line clear and draining freely.
- Room hygiene, floor cleaning, no product touching evaporator throw.
Monthly checks
- Refrigerant sight glass, suction and discharge pressures logged.
- Electrical panel — check contactors, cables, tightness of connections.
- PUF panel joints and roof for damage or moisture ingress.
- Door hinges, gaskets and heater wire (for frozen rooms) working.
Annual / AMC checks
- Compressor oil condition and change per manufacturer recommendation.
- Refrigerant charge and leak test.
- Evaporator deep clean and defrost heater check.
- Control panel wiring inspection, safety device testing.
- Insulation inspection, sealant refresh on panel joints.
Common mistakes
- Ignoring dirty condenser coils — a leading cause of compressor failure in Indian summer.
- Blocking evaporator air throw with product stacks.
- Skipping drain line cleaning — leads to ice build-up and water ingress.
- Not logging temperature — makes fault diagnosis impossible.
