Commercial Refrigeration Maintenance in Auburn, WA

Every maintenance visit starts here. A coated coil cannot shed heat efficiently, full stop, and that inefficiency compounds every hour the unit runs until the next cleaning. We do not skip this step regardless of how the rest of the unit looks.

Fan blades, motor operation, actual air movement through the box, all three get physically checked rather than assumed fine because the unit sounds normal. Airflow problems mimic refrigerant problems closely enough to fool an untrained eye.

Timer, heater, thermostat: we run these through a live cycle instead of trusting that the unit looks frost-free today. Defrost failures develop gradually, and gradual is exactly what makes them easy to miss without testing.

The gasket gets inspected, sure, but so does everything holding it in place. A hinge that has drifted out of alignment can undo a perfectly good seal without anyone realizing why cold air keeps escaping.

What the display reads and what the box actually holds are not guaranteed to match on equipment that has been in service a while. We check both numbers, since a controller running warm is a health code issue long before it is a mechanical complaint.

Standing water starts small: a slightly slow drain nobody notices for weeks. By the time it is a puddle, it is also a liability. Clearing the line during a routine visit stops that progression before it starts.

Every contactor and relay gets checked for heat damage, because electrical parts in refrigeration equipment tend to work fine right up until they do not, with very little warning in between.
