A walk in that was installed badly costs money every day it runs. JRC installs walk in coolers and freezers across Hampton, SC for new builds, replacements and kitchen expansions.
The details that decide whether a box performs are mostly invisible once it is running: correct condensing unit sizing for the actual load rather than the floor area, line set sizing and oil return on long or vertical runs, adequate clearance and airflow around the condenser, floor insulation and a heater wire on freezer door frames. We also set the controls properly rather than leaving factory defaults, because a defrost schedule that suits a bakery is wrong for a busy bar.
