A dirty condenser coil is the single most common reason commercial refrigeration underperforms, and it is entirely preventable. JRC cleans condenser coils throughout Washington, DC on walk ins, reach ins, display cases and remote condensing units.
The coil rejects the heat your system pulls out of the box. Blanket it in grease, flour and dust and head pressure climbs, capacity falls, run time goes up and the compressor works harder for less cooling. In a commercial kitchen a coil can pack solid within months. We clean with proper coil cleaner and a comb rather than blasting the fins flat with a pressure washer, then take pressures before and after so you can see the difference on paper.
