    Commercial Refrigeration Preventive Maintenance

    Scheduled refrigeration maintenance for restaurants, commissaries, grocery, and institutional kitchens across the NYC metro. Hold product temperatures, protect inventory, and stay HACCP-ready while avoiding the compressor failures that take a kitchen offline.

    Refrigeration Failures We Catch Before They Spoil Inventory

    Box temperature drifting above setpoint

    A walk-in or reach-in slowly climbing out of safe holding range usually traces to a dirty condenser, low refrigerant charge from a leak, or an iced evaporator from a failed defrost — all caught on a PM before product crosses the danger zone.

    Evaporator coil frozen into a block of ice

    Failed defrost heaters, a stuck defrost termination, or low charge cause ice to bridge the coil, killing airflow and cooling. PM checks defrost cycle timing and termination so the coil clears every cycle.

    Compressor short-cycling or running constantly

    Dirty condensers, failing contactors, low charge, or control faults make compressors short-cycle or never shut off — driving up amp draw, head pressure, and the risk of a burnout that strands the box.

    Water pooling on the floor under the unit

    A clogged condensate drain line or failed pan heater backs water into the box and onto the floor — a slip hazard and a sign the drain needs flushing and the heater verified before it freezes solid.

    Refrigerant leak and rising operating cost

    Leaking fittings, vibration-cracked lines, or eroded coils bleed off charge, starve the evaporator, and run the compressor hot. We leak-test and log refrigerant under EPA 608 to catch loss early and plan the repair.

    Doors not sealing and frost buildup at the frame

    Worn gaskets, sagging hinges, and failed heated frames let humid kitchen air infiltrate — frosting the entrance, overworking the compressor, and spiking energy use until the seal is restored.

    Refrigeration Uptime Is Food Safety and Revenue

    In a food-service facility, refrigeration is the most failure-prone, hardest-working equipment you own — condensing units cycle continuously, walk-in evaporators run defrost cycles around the clock, and a single iced-over coil or failed compressor can spoil thousands of dollars of inventory overnight while putting you out of HACCP temperature compliance. Com+ Mechanical delivers scheduled preventive maintenance built specifically for commercial refrigeration: walk-in coolers and freezers, reach-ins, prep and pizza tables, condensing units, multiplex rack systems, and ice machines. Our PM program targets the failures that actually shut kitchens down — dirty condensers driving high head pressure, refrigerant leaks under EPA Section 608, clogged condensate drains, worn door gaskets, and defrost faults — across single locations and multi-unit restaurant portfolios throughout the five boroughs, Nassau, Westchester, northern New Jersey, and Stamford.

    What a Refrigeration PM Visit Includes

    Clean condenser coils and verify head pressure, discharge temperature, and condenser fan operation on every condensing unit
    Inspect evaporator coils and verify defrost cycle, defrost heaters, and termination on walk-in and reach-in systems
    Check refrigerant charge via superheat and subcooling; leak-test circuits and log refrigerant per EPA Section 608
    Clear and flush condensate drain lines and pans; verify drain-line heaters on freezer systems to prevent ice blockage
    Test and calibrate temperature controls, thermostats, and digital controllers against HACCP holding setpoints
    Inspect and adjust door gaskets, hinges, closers, and heated frames; verify door seal integrity on coolers and freezers
    Measure compressor amp draw, contactor condition, and crankcase heater operation; verify oil level on rack compressors
    Check electrical connections, capacitors, relays, and fan motor bearings; document all readings on a per-unit service log

    Why Facilities Put Refrigeration on a PM Program

    Protect inventory — stable holding temperatures keep product out of the danger zone and prevent overnight spoilage losses
    Stay HACCP-ready — documented temperature logs and calibrated controls support health-department and audit requirements
    Avoid emergency callouts — catching dirty condensers, weak contactors, and low charge early prevents compressor burnouts
    Lower operating cost — clean coils, proper charge, and sealed doors cut runtime and energy draw on every box
    Extend equipment life — reducing head pressure and amp draw protects compressors and defers costly replacements
    Portfolio consistency — standardized PM scopes and per-unit logs across every location in your restaurant group

    Our Simple Process

    From call to comfort in 4 easy steps

    1

    Equipment Survey

    We inventory every refrigeration asset — walk-ins, reach-ins, prep tables, condensing units, racks, and ice machines — logging make, model, refrigerant type, and baseline operating conditions per unit.

    2

    PM Plan and Schedule

    We build a maintenance scope and visit frequency matched to your equipment load and kitchen hours, scheduling around service so PM work never interrupts production.

    3

    Scheduled Service Visits

    Technicians perform the full PM checklist on each unit — cleaning, leak-testing, defrost and control verification, and electrical checks — recording readings on a per-unit service log.

    4

    Reporting and Recommendations

    You receive documented findings, temperature and refrigerant logs, and prioritized recommendations for any repairs or replacements before they become emergencies.

    Types of Systems We Install

    Walk-In Coolers and Freezers

    Built-up and pre-fab walk-in boxes with remote or top-mount condensing units, the highest-load and most failure-prone refrigeration in most kitchens.

    • Defrost cycle, heater, and termination verification
    • Drain-line and pan-heater service to prevent ice blockage
    • Door gasket, sweep, hinge, and heated-frame inspection
    • Condensing unit head-pressure and charge checks

    Reach-In, Prep, and Undercounter Units

    Self-contained reach-in coolers and freezers, sandwich and pizza prep tables, and undercounter units on the line where airflow and condensate management are critical.

    • Condenser coil cleaning in grease-heavy line locations
    • Gasket and lid-seal inspection on prep tables
    • Condensate drain and evaporator airflow checks
    • Thermostat and controller calibration to holding temps

    Ice Machines and Self-Contained Refrigeration

    Cubers and flakers plus self-contained merchandisers and display cases, where water quality, scale, and condenser cleanliness drive reliability and sanitation.

    • Condenser cleaning and water-system inspection
    • Descaling and sanitation of ice-contact surfaces
    • Harvest cycle and water-level control verification
    • Bin and drain inspection for sanitation compliance

    Why Com+ Mechanical for Commercial Refrigeration

    Commercial Food-Service Focus

    We work exclusively in commercial environments — restaurants, commissaries, grocery, and institutional kitchens — not residential fridges. We understand HACCP holding requirements and kitchen uptime pressure.

    24/7 Emergency Response

    PM clients get priority access when a box goes down. We respond around the clock across the NYC metro so a failed compressor doesn't become a spoiled walk-in.

    EPA-Compliant Refrigerant Handling

    We leak-test, recover, and log refrigerant in line with EPA Section 608, and support the transition off R-404A to lower-GWP alternatives like R-448A/R-449A.

    Portfolio-Ready Service

    From a single kitchen to a multi-location restaurant group, we standardize PM scopes, consolidate reporting, and keep per-site equipment histories for facility and operations teams.

    Transparent Pricing

    No fees. No surprises. Just honest service.
