Commercial Refrigeration Installation Across the NYC Metro

When a condensing unit is selected off a rough square-footage guess instead of an actual load calc, it runs nonstop on a 95F NYC afternoon and still drifts warm. We size against real product load, door traffic, and design-day ambient so the box pulls down and holds.

Skipped nitrogen purge during brazing, a shallow evacuation, or a failed vapor barrier lets moisture into the system and the structure. We braze under flowing nitrogen, pull a deep micron-level vacuum, and detail vapor-tight panel seams to keep the box dry.

Poor condenser airflow, an overcharge, or wrong control differentials hammer the compressor and shorten its life. We set proper condenser clearance, charge by weight or subcooling, and program realistic cut-in/cut-out and anti-short-cycle timing.

A drain line run through a freezer without heat trace freezes solid and floods the floor. We slope drains correctly, add P-traps, and heat-trace any line passing through freezer or unconditioned space so water actually leaves the box.

Non-NSF panels, missing condensate handling, improper refrigerant line support, or no machine-room ventilation stall your opening. We build to NSF, mechanical, and NYC code so the install passes the first time.

A self-contained condensing unit dumping heat into a cramped kitchen overloads the space and the equipment. Where the layout calls for it we specify a remote condensing unit on the roof or in a machine room to move heat and noise out of the work area.
