Commercial Refrigeration Maintenance in Everett, WA

We start every maintenance visit at the condenser coil, since a dirty coil is the single biggest driver of a rising electric bill on equipment that otherwise looks fine. The compressor works harder to push heat through blocked fins, and that strain compounds every day the coil stays dirty. Manufacturer cleaning schedules tend to underestimate how often a busy kitchen actually needs this done.

Fan condition, blade wear, and whether cold air actually reaches the far corners of the box all get evaluated here. A common mistake is chasing a refrigerant leak that does not exist, when restricted airflow at the evaporator is really what is causing the warm spots and uneven freezing.

Rather than trust that the heater, timer, and thermostat are working just because the box looks cold today, we run the whole defrost system through a full cycle. Ice buildup from a failing defrost component develops slowly, which is exactly why it tends to go unnoticed until the unit is already struggling.

Hinges and closers matter as much as the gasket itself, since loose hardware can hold a seal open just enough to let humid air in continuously. Fixing this early is inexpensive. Letting it go raises both the power bill and the rate of ice buildup for as long as it sits unaddressed.

We compare what the digital controller reports against the actual temperature inside the box, since these numbers can drift apart on older equipment without anyone noticing. A controller reading even a few degrees warmer than reality becomes a food safety concern before it ever registers as a mechanical one.

A drain line that runs slow or was routed wrong sends water onto the floor instead of out of the building, and that is both a slip hazard and something a health inspector will flag without hesitation. Clearing it during a scheduled visit takes a few minutes. Dealing with it as an emergency call takes considerably longer.

Every contactor, relay, and wire connection gets checked for wear and heat damage as part of the visit. This is frequently the step that catches a problem before it becomes one, since electrical components in refrigeration equipment tend to fail suddenly rather than gradually.
