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
Why Facilities Put Refrigeration on a PM Program
Our Simple Process
From call to comfort in 4 easy steps
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.
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.
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.
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.

- Refrigerant leak check and charge verification
- Prioritized findings and recommended PM plan
Preventive Maintenance Agreement
Scheduled recurring PM visits across all refrigeration units, sized to your kitchen hours and equipment load.
- Recurring visits on a set frequency
- Full per-unit PM checklist each visit
- Coil cleaning, defrost, and control verification
- Refrigerant logging per EPA Section 608

Frequently Asked Questions
Get answers to common questions about our services
How often should commercial refrigeration be serviced?
Most food-service facilities benefit from quarterly PM visits, with high-load equipment like walk-in freezers and condensing units checked more frequently. We set frequency based on your equipment count, kitchen hours, and ambient conditions during the assessment. High-grease environments often need condensers cleaned more often.
Do you respond to refrigeration emergencies after hours?
Yes. We provide 24/7 emergency response across the NYC metro, and preventive maintenance clients receive priority dispatch when a unit goes down. Because spoiled inventory and HACCP violations happen fast when a box loses cooling, fast response is built into our program.
Can you maintain refrigeration across multiple restaurant locations?
Yes. We support multi-unit restaurant groups and facility portfolios with standardized PM scopes, consolidated reporting, and per-site equipment histories — so operations teams get one consistent program and a single point of contact across the five boroughs, Nassau, Westchester, northern NJ, and Stamford.
Does maintenance help with HACCP and health-department compliance?
It does. Calibrated temperature controls, verified defrost cycles, and documented per-unit temperature logs support HACCP holding requirements and give you records to show during health-department inspections. Stable holding temperatures keep product out of the danger zone between visits.
How does refrigeration maintenance reduce energy costs?
Dirty condensers, low refrigerant charge, iced evaporators, and worn door gaskets all force compressors to run longer and draw more power. PM restores clean coils, proper charge, working defrost, and tight door seals — cutting runtime and energy use, which also supports Local Law 97 building emissions goals for NYC facilities.
Do you handle refrigerant leaks and the R-404A phase-down?
Yes. We leak-test circuits, recover and log refrigerant under EPA Section 608, and help facilities transition older R-404A systems toward lower-GWP alternatives such as R-448A and R-449A. Catching leaks early on a PM protects the compressor and reduces refrigerant cost.
