Commercial Refrigeration Maintenance in Bellevue, WA

A dirty coil is the most common reason a well-maintained unit still runs a high electric bill. Every layer of grease and dust it picks up makes the compressor push harder for the same result, and that strain adds up over months rather than one bad day. Kitchens near heavy fryer or grill lines tend to need this step more often than the manufacturer schedule suggests.

This step covers the fan motors, blade condition, and whether cold air is actually reaching where it needs to. A blocked return often looks like a refrigerant problem from the outside, with warm spots near the door and frost forming somewhere it should not.

The heater, timer, and termination thermostat all get run through a full cycle rather than checked by eye alone. A defrost fault can sit unnoticed for weeks before ice buildup finally chokes airflow enough to cause a real failure.

Hinges, closers, and the gasket itself all get checked together, since a seal can look fine while the hardware holding it in place has gone loose. A gap barely visible to the eye still lets in enough humid air to noticeably speed up frost buildup.

We check the real box temperature against both the setpoint and what the digital controller displays, since those two numbers drift apart over time on older units. A controller reading a few degrees optimistic is easy to miss until product starts arriving soft.

A slow or blocked drain sends water onto the floor instead of out of the unit, creating both a slip hazard and something a health inspector will flag on sight. Clearing a line takes only a few minutes during a maintenance visit versus an emergency call later.

Contactors, relays, and every connection point get checked for heat damage and wear. This is usually the item that catches a failure before it happens, since electrical components tend to fail without much warning otherwise.
