Commercial Refrigeration Maintenance in Brier, WA

Condenser coils collect grease steadily and quietly, and the compressor absorbs the cost in longer cycles and higher temperatures. This is where every visit starts because it changes everything measured afterward.

We confirm the evaporator fan actually moves air rather than assuming it does. Restricted circulation and low charge look alike from outside, and only one of them is fixed by adding refrigerant.

Each defrost component gets exercised through a complete cycle. There is no way to judge a heater or timer by inspection alone, and ice on the coil means the fault predates the symptom by weeks.

The gasket is only half the seal; the hinge and closer are the other half. When any of them go, warm air enters continuously and the unit never stops paying for it.

Three numbers get compared: what you set, what the controller shows, and what the box actually holds. Divergence there is a food safety problem well before it is a mechanical one.

Blocked drains send condensate onto the floor instead of down the line. That is a slip hazard and an inspection finding at once, and clearing it is a matter of minutes.

Wear and heat damage on contactors and connections get examined every time. This is the failure class with no build-up phase: the unit runs normally until it does not run at all.
