Commercial Refrigeration Maintenance in Kent, WA

You will notice a dirty coil on your power bill before you notice it anywhere else. Grease and dust act like a blanket over the coil, and the compressor has to fight through that layer to hit the same setpoint. We clean coils every visit, not just when someone asks.

Warm spots near the door, product freezing where it should not: both point to airflow problems more often than refrigerant problems, even though refrigerant gets blamed first. Fan motor operation and blade condition get checked here specifically to rule that out.

Ice does not build up overnight from a failing defrost system, it builds up over weeks. That is the problem: by the time it is visible, the heater, timer, or thermostat has likely been failing for a while. We run the full cycle rather than eyeball it.

A gasket can look perfectly fine while the hinge holding it is loose enough to let it gap open under pressure. We check both together, since hardware failure is the less obvious of the two and the one people miss.

Two numbers matter here: what the controller says, and what the box actually is. On older units those numbers can drift apart, and a controller reading warm turns into a food safety problem before anyone notices a mechanical one.

A five-minute fix during a scheduled visit versus a slip-hazard puddle and a health code writeup later, that is the choice with a slow drain line. Clearing it takes almost no time when it is part of a planned visit.

Electrical components rarely warn you before they fail. Contactors, relays, connection points, all get checked for heat damage here specifically because catching wear early is usually the only warning you get.
