Commercial Refrigeration Maintenance in Redmond, WA

Skip this one and everything else on the list works harder than it should. A dirty coil forces the compressor to run longer for the same result, and that inefficiency compounds daily. We treat coil cleaning as the anchor of every visit, not an optional add-on.

Fan motors get tested for actual operation, not just spun by hand. Blade condition and airflow reaching every corner of the box both get checked here, since restricted circulation is commonly mistaken for a refrigerant problem when it isn’t one.

Heater, timer, thermostat, run through a complete cycle rather than inspected visually. A defrost fault stays hidden until ice has already built up enough to hurt performance, which is exactly why a visual check alone isn’t reliable.

Hinges and closers matter as much as the gasket. A seal can look intact while loose hardware is quietly letting it gap open, and that gap drives up both the power bill and ice accumulation for as long as it goes unnoticed.

The controller says one thing, the actual box temperature says another, and on older equipment those two numbers drift apart more than most operators realize. We check both, since a controller reading warm becomes a food safety issue before it registers as anything else.

A slow drain means water on the floor instead of water leaving the unit, and that is a slip hazard as much as a health code problem. Clearing it during a scheduled visit is a five-minute job. Waiting until it’s an emergency call turns it into something bigger.

Contactors, relays, every connection point, checked for heat damage and wear. Electrical failures in refrigeration equipment rarely give advance warning, which makes this step the one most likely to catch something before it becomes a shutdown.
