Winter is hard on restaurant equipment. Months of heavy heating cycles, condensation buildup, and grease accumulation leave systems worn down right as spring brings rising temperatures, reopened patios, and increased foot traffic. For multi-location operators, that combination is a real pressure test, and the restaurants that pass it are the ones that ran a thorough spring preventive maintenance sweep before the season hit.

This checklist is built from actual restaurant preventive maintenance work orders across HVAC, refrigeration, hood cleaning, fire safety, drains, grease, pest control, and kitchen equipment.

Why Spring Is the Critical Maintenance Window for Restaurants

Several things converge in spring: temperatures climb, volume picks up, outdoor dining reopens, and equipment that ran hard all winter is at its most worn.

Refrigeration is stressed coming out of winter. Restaurant kitchens generate heat, grease, and airborne debris at a rate that gunks up condenser coils fast. Equipment manufacturers like True recommend cleaning condenser coils every 30 days in kitchen environments. When coils are clogged, the compressor works harder to hit the same temperatures. A compressor that's been straining since January is most likely to fail in May, when ambient temps rise and it has even less margin. The repair is expensive; the food loss and health code exposure that come with a walk-in failure are worse.

HVAC transitions from heating to cooling mode. This is one of the most common failure points of the year. A unit that ran without issue all winter can fail on its first cooling call in April. Catching that in a spring inspection is a scheduled work order. Missing it is an emergency call in June.

Hood and exhaust systems carry months of accumulated grease buildup. Grease buildup in kitchen exhaust systems is one of the leading causes of restaurant fires, and local fire codes set cleaning frequency requirements specifically because the risk compounds over time. As kitchen temperatures climb heading into summer, the window to address it safely gets shorter.

Pest pressure increases with the temperature. A gap that went unnoticed in February can become an active entry point by May. Warm weather, outdoor dining, and delivery traffic all raise exposure.

Health inspections pick up as dine-in traffic returns. Issues that surface during a spring inspection are much cheaper to address than the same issues surfacing during a summer health inspection or a busy Saturday service.

How to Use This Checklist

This is a starting point, not a complete picture of every location's needs. A quick-service chain and a full-service steakhouse both need their walk-ins serviced in spring, but beyond that their equipment inventories, lease obligations, and compliance requirements diverge. Before rolling this out, review each section against your actual asset list, cut what doesn't apply, and expand anything that touches your most critical systems.

A Note on Licensed Work

Some tasks on this checklist, including refrigerant handling, gas line work, fire suppression inspection, hood cleaning, and live electrical work, are legally required to be performed by a qualified vendor in many jurisdictions. Requirements vary by location, so check what applies to your sites. When in doubt, call the right service provider. The cost of an unnecessary vendor visit is almost always lower than the cost of getting it wrong.

The Checklist

HVAC, Make-Up Air, and Ventilation

Most operators don't think about HVAC until something breaks. A rooftop unit that ran all winter without issue can fail on its first cooling call in April: seized bearing, split belt, clogged condensate drain, contactors that have been arcing since November. The spring visit is the diagnostic, not just the maintenance.

  • Replace and date all air filters on rooftop units, dining-room returns, kitchen units, make-up air units, office units, and spot coolers.
  • Inspect belts, pulleys, blower shafts, bearings, and fan motors; align and replace worn belts during this visit.
  • Clean condenser coils, evaporator coils, fins, blower wheels, and outside-air intake screens.
  • Flush condensate pans and drains; confirm drain lines are connected, flowing freely, and not leaking.
  • Test cooling start-up, thermostat operation, stage control, economizer and low-ambient controls, and heating and cooling safeties.
  • Check compressor and blower amperage, contactors, wiring, disconnects, refrigerant pressures, sight glass, and visible oil levels where applicable.
  • Inspect exhaust fans and make-up air units: belts, bearings, dampers, ignition or heat exchanger condition, filter media, and water or float systems on evaporative equipment.
  • Re-secure panels and access doors, verify units are fully operational at departure, and document any deficiency that needs a separate repair work order.

Refrigeration, Walk-Ins, Freezers, and Ice Machines

Most refrigeration failures have a paper trail if you know where to look: temperature logs that trend a degree or two warm over several weeks, a compressor cycling more than usual, a gasket that's been flagged soft but never replaced. The work order gets generated when the walk-in fails on a Saturday night, but the signal was there weeks earlier.

  • Clean condensers and accessible coils on walk-ins, walk-in freezers, reach-ins, lowboys, prep coolers, and bar refrigeration.
  • Inspect evaporators, fan guards, and fans for dirt, frost buildup, unusual noise, or damage.
  • Flush condensate pans and drains; confirm drain heaters, water-regulating components, and pans are working where applicable.
  • Check thermostat settings, box or product temperatures, controls, and normal equipment cycling.
  • Check defrost timers, defrost settings, and defrost termination function.
  • Inspect door gaskets, hinges, latches, and self-closing hardware on walk-ins and reach-ins; note any tears, gaps, or misalignment.
  • Inspect wiring, controls, contactors, compressor amperage and oil sight glass, and any visible signs of refrigerant leaks or oil staining.
  • Ice machines: clean and sanitize per manufacturer, clean condenser and evaporator surfaces, verify bin stat, freeze and harvest cycles, and ice thickness control.
  • Check and date water filters serving ice machines or water-cooled equipment; open follow-up work orders for replacements not completed during this visit.

Kitchen Hood, Duct, Exhaust, and Fire Suppression

Hood cleaning is a legal requirement in most jurisdictions, and the certificate your vendor issues is what you produce when a fire inspector, insurer, or investigator asks. What many operators don't realize is that hood interiors, the exhaust fan, and the ductwork all have separate service intervals and are not all on the same schedule.

  • Clean hood filters or baffles, grease troughs, removable grease cups, and accessible hood interiors.
  • Clean exhaust fan housing and blades; inspect belts and replace worn belts if needed.
  • Clean accessible vertical and horizontal ductwork on the required interval; confirm whether the site is currently due.
  • Inspect and service pollution control units, precipitators, or odor-control, charcoal, bag, or MERV filters if the site uses them.
  • Confirm grease containment pans, hinges, access doors, rooftop fan access, and warning signage are present and functioning.
  • Complete hood fire suppression or Ansul inspection: verify nozzle coverage and position, fusible links, pull station, microswitches, gas valve shutoff, remote and manual actuation, and service tags.
  • Verify exhaust fan operation, filters in place, portable extinguishers present, and any inspection tags or annual service records required at the site.

Hot-Side Kitchen Equipment and Water-Fed Equipment

Hot-side equipment gets cleaned daily, which creates a false sense of security about its actual condition. The burner gasket on a fryer doesn't get checked during the nightly clean. Neither does the heat exchanger, the thermostat calibration on the oven, or the water filter on the combi. These are the things that affect food quality, energy consumption, and equipment lifespan, and they drift quietly until something breaks or fails an inspection.

  • Ovens: calibrate thermostats, inspect burners or pilots, electrical connections, door seals and hinges, door switch operation, and blower or cooling fan pathways.
  • Fryers: clean burner area, heat exchanger, flue, and burner gasket; note any warped, leaking, or failing components.
  • Broilers, grills, and griddles: remove grease buildup from burner compartments and flues, clean filters, and lubricate rollers or bearings where specified.
  • Salamanders, smokers, pizza ovens, and other high-heat specialty equipment: clean grease and debris, inspect burners, and stage replacement parts if worn.
  • Combi, Rational, or other water-fed hot equipment: check Mavea or other water filters, drain hoses, and air filters; replace and date filters if due.
  • Beverage and hot water equipment: descale towers or warmers, change coffee or espresso filtration, and check any water-fed countertop equipment that runs year-round.

Plumbing, Drains, Grease, and Water Systems

Grease interceptors and floor drains fail slowly, which makes them easy to deprioritize. The grease trap doesn't back up overnight. It builds over weeks until it does, usually during a high-volume shift when the kitchen is least equipped to deal with it. A slow floor drain in the dish area becomes standing water and a slip hazard. Whatever state these systems are in now, they'll be under more stress by summer.

  • Hydro-jet or mechanically clean kitchen and bar drain lines to the grease trap if spring drain flushing is part of this site's scope.
  • Flush and clean grease-trap inlet and outlet piping and the line from the grease trap to the sanitary main.
  • Pump or clean grease traps or interceptors on the site frequency; collect manifest, photos, and service report.
  • Inspect floor drains, dish-area drains, sinks, P-traps, and cleanouts for buildup, slow flow, or visible damage.
  • Inspect ejector pits, floats, pumps, and pit condition if the site uses an ejector system.
  • Check water filters and pre-filters at bar, dish, coffee, ice machine, and hot water points; replace and date filters if due.
  • Service water heaters per manufacturer: flush or descale, clean inlet and vent screens, recharge condensate neutralizer if present, and check for leaks after restart.
  • Complete backflow or RPZ testing and required municipal paperwork if that inspection falls in the spring window.

Pest Control, Exterior, Lighting, and Building Envelope

Winter creates gaps. Door sweeps compress and stop sealing. Weather stripping tears. Expansion joints crack. None of it feels urgent in February when rodent activity is low, but pest pressure follows temperature, and by May the same gaps that were theoretical become active entry points.

  • Confirm monthly or bi-weekly pest service is active before warm-weather traffic, deliveries, and open-door activity increase.
  • Exterior pest inspection: check dumpster or grease-bin area, smoker or service-yard area, rodent burrows along the foundation, bait stations, perimeter treatment, and door closure.
  • Interior pest inspection: check behind fryers and prep lines, floor drains, soda or tea stations, dry storage, door sweeps, and weather stripping.
  • Replace glue boards or service traps and bait stations; document sightings, trending activity, and any sanitation or exclusion issues.
  • Check parking-lot lights, building lights, canopy lights, signage, pylon signs, and lighting timers.
  • Walk the building exterior and roof-access path: exterior doors, latches, weather stripping, windows, rooftop area around equipment, storage areas, and visible trip hazards.
  • Clean the dumpster corral or service area and note standing water, grease buildup, or housekeeping issues that attract pests.

Safety and Compliance

Fire extinguishers, emergency lighting, exit signs, and health permits are the kind of items that get checked during inspections but often go untouched in between. They're easy to assume are fine. Spring is the right time to verify them deliberately rather than discovering a dead battery backup or an expired certificate during an actual inspection.

  • Emergency lights and exit signs checked; failed bulbs or battery backups replaced or flagged immediately.
  • Portable extinguishers are current, accessible, and tagged; annual inspections are on schedule.
  • Fire alarm, sprinkler, or monitoring status confirmed if those systems are included at this site.
  • Health permit, fire-safety documents, hood-cleaning certificate, and backflow or fire inspection records are posted or filed where required.

When to Escalate to a Professional

If the work involves a licensing requirement, specialized equipment, or a mistake that could injure someone or cause significant disruption to operations, it belongs with a professional.

  • Refrigerant work requires a qualified refrigeration or HVAC technician and is not an in-house task
  • Gas line inspection and repair means anything beyond a visual check on connections goes to a qualified technician
  • Electrical panel work is reasonable to inspect visually in-house, but anything involving the panel itself requires a qualified electrician
  • Fire suppression system inspection is required by code in most jurisdictions and must be performed by a qualified fire protection contractor
  • Hood cleaning is required by law in most jurisdictions and must be performed by a trained vendor who can issue a cleaning certificate
  • Pest remediation means prevention and monitoring can be handled in-house, but active infestations require a qualified pest control operator

For multi-location operators, a vetted vendor list for each of these categories, with contacts, service history, and response time expectations on file, makes escalation faster and less costly when something goes wrong.

The Close-Out Package

Preventive maintenance isn't complete when the work is done. It's complete when everything is documented and the site manager has reviewed the findings. The hood certificate that never gets uploaded, the deficiency list that stays in someone's notebook, the manager sign-off that never happens: these are the things that become problems when a fire, injury, or inspection surfaces an issue at a location.

Before closing or invoicing any site:

  • Review findings and recommendations with the GM or manager on duty.
  • Technician report or findings uploaded.
  • Before and after photos uploaded for coils, filters, hood work, or any major buildup found.
  • Grease-trap manifest or drain service report uploaded if applicable.
  • Hood-cleaning certificate and fire-suppression or extinguisher inspection documents uploaded if applicable.
  • Pest-control service report uploaded if applicable.
  • Water-heater, backflow, or specialty-equipment reports uploaded if applicable.
  • Corrective work orders or quotes opened for all deficiencies, parts needs, and items requiring specialist follow-up.
  • Manager sign-off obtained confirming the spring preventive maintenance was reviewed and completed.

Tie your findings to your asset records too. If a walk-in condenser has been serviced three times in 12 months, that's a replace conversation, not another repair order.

From Checklist to Maintenance Program

Running this checklist gives you something concrete: a documented record of what was serviced, what was found, and what needs follow-up before summer volume hits. That's the difference between a proactive facilities program and one that's always reacting to the last failure.

The harder part is making sure the findings actually turn into action. When a technician flags a failing door gasket on a walk-in at location 12, a paper form doesn't automatically create a work order, notify anyone, or attach to that asset's history. Deficiencies get buried in notes. Corrective work gets missed. The same issue shows up again in six months.
