Commercial Refrigeration Maintenance in Lynnwood, WA

Ask any tech what gets skipped most, and coil cleaning tops the list. It is not glamorous work, but a clean coil is the difference between a compressor running efficiently and one straining to hit the same setpoint every cycle.

An evaporator fan does not get much attention until it fails completely, and by then you usually have warm spots and uneven cooling that everyone blamed on refrigerant. We check blade condition and actual airflow here, not just whether the fan spins.

A defrost system can fail slowly enough that nobody notices for weeks. We run the heater, timer, and thermostat through a real cycle rather than checking whether the unit looks cold today, since looking cold today does not rule out a problem building underneath.

Hardware, not just the gasket, is the distinction that matters here, since a hinge or closer that has gone loose can hold a perfectly good seal open just enough to leak air continuously.

The controller display and the actual box temperature are not always the same number on older equipment. We verify both, because a controller reading a few degrees warm is a food safety problem long before it looks like a mechanical one.

Water on the floor from a slow drain is a slip hazard and a health code issue rolled into one, and it is completely preventable. Clearing a line during a scheduled visit is a five-minute job.

Contactors, relays, connection points, checked for heat damage every visit. Electrical components in this equipment do not usually give much warning before they fail, so this step is about catching problems nobody can see yet.
