Setting up equipment repair and preventive maintenance before something dies

Why the first call shouldn't be a web search during a breakdown

Owners often start looking for a technician only after something has already failed. A r/restaurantowners post asking how others manage equipment repair and maintenance came from someone helping a family member launch a restaurant. A used deep freezer they had bought had failed, with no warranty, and the poster asked whether owners keep an on-call repair person or attempt repairs themselves. That's the moment when your choices are fewest. The freezer is warming, the product is at risk, and whoever answers the phone gets the job.

There's a capacity problem too. In a thread where a refrigeration technician asked how restaurants find service, the poster said their current employer always has a backlog of calls. If that's typical where you are, and it will vary by market, a new customer calling in a crisis is at the back of the queue. An existing customer with a service history may get seen sooner. Both threads were recorded as search excerpts. They describe single situations, not industry statistics, but the lesson holds: the relationship has to exist before the emergency.

Build a vendor roster by trade, with a backup for each

List every trade your kitchen depends on, then name a primary and a backup vendor for each. For each vendor, collect the same details: the after-hours number and how after-hours calls are billed, a rate sheet showing trip charges, hourly rates and minimums, the equipment brands they're authorized to service for warranty work, and their typical response time for an existing customer. Where your jurisdiction licenses a trade, check the license in the issuing agency's lookup. Don't take a business card's word for it.

The reply in the technician's thread, which advised dropping off a pricing sheet at restaurants outside of busy service, points to a simple habit: ask every vendor for a written rate sheet and file it. When a bill arrives, you can compare it with what you agreed to, not with what you remember.

A preventive maintenance calendar you can actually keep

Preventive maintenance is mostly a list of small jobs done on time. Start from the manufacturer's manual for each unit, which sets cleaning and service intervals and sometimes ties warranty coverage to them. Add anything your local fire, health or utility rules require, such as hood and suppression service or grease interceptor pumping, at the frequency those rules set. Then fill the gaps with the operational routines below. These are suggestions, not code requirements. Adjust the frequency to your grease load and usage.

Evaluating a technician by the diagnosis, not the hourly rate

The r/restaurantowners refrigeration-issues thread includes a pointed comment from an owner. They said they don't mind paying $100 or more an hour for someone who knows what they're doing, and that the people who really know are often cheaper. But they had repeatedly paid service companies whose technicians treated coil washing or filter changes as the fix for everything, and once paid about $120 an hour for a technician to sit on hold with the manufacturer. Calling manufacturer support isn't wrong in itself. What frustrated the owner was paying for a visit that never reached a diagnosis.

That suggests what to look for. A good technician explains what they measured and what it showed. They name the failed part, ideally with a part number. They distinguish the root cause from the symptom, and they tell you what would make the problem come back. A weak visit ends with a generic task, 'cleaned coils, unit running', on a unit whose coils were already clean, and no readings recorded. Ask, politely, on every call: what did you find, how did you confirm it, and what should we watch for? You'll learn quickly which technicians can answer.

• Good sign: records readings such as temperatures and pressures or amp draw, and leaves them on the invoice.
• Good sign: explains the cause, not just the action taken.
• Good sign: tells you when a repair isn't worth it compared with replacement.
• Warning sign: the same generic fix on repeat visits for the same symptom.
• Warning sign: billing for time on hold or for research without saying so up front. Ask how this is billed before the visit.

Worked example: the cheaper visit that cost more (hypothetical numbers)

All figures are hypothetical, chosen to show the arithmetic. A reach-in is warming in the afternoons. Technician A charges a $95 trip fee and $120 an hour. They spend two hours, clean the condenser and leave the unit running. The invoice is $95 + (2 × $120) = $335. Nine days later the unit warms again. Technician B charges a $125 trip fee and $140 an hour. They spend 1.5 hours, record that the evaporator fan isn't running at full speed, and replace the fan motor with an $85 part. The invoice is $125 + (1.5 × $140) + $85 = $420.

The owner paid $335 + $420 = $755 to fix a problem that Technician B's single visit solved for $420. The extra $335 bought nothing, and the second warm spell put food at risk again. Technician B's hourly rate was higher, but the cost per resolved problem was lower. When you review service invoices each quarter, measure vendors by repeat calls for the same symptom, not by rate.

Service records that make the next decision easy

Keep one log for the whole kitchen, with one line per service call. Record the date, the unit and its serial number, the vendor and technician, the symptom reported, what was found, parts replaced, readings taken, the cost, the time from call to arrival, and the time the unit was out of service. Attach the invoice. Within a year this log shows which units are failing repeatedly, which vendors fix things the first time, and how fast each vendor really responds.

Some records are also inspection documents. In the District of Columbia, DC Health's Understanding Food Establishment Inspections page says an establishment must give the inspector proof of trash pickup, extermination and, where necessary, grease collection, usually through invoices or contracts. The page also notes that inspection reports list the trash, pest control and grease collection contractors. Other jurisdictions have their own documentation rules, but keeping contracted-service paperwork in one place is a good habit anywhere.

A one-page outage plan

Write the plan before you need it, and post it where the closing manager will find it. For refrigeration, the plan matters for food safety as well as convenience. In DC, the same DC Health page lists inadequate refrigeration among the conditions that can justify suspending a license for an imminent health hazard. It also gives refrigerator repair or replacement as an example of a violation that can't be corrected on site. Know your jurisdiction's equivalent rules.

• Who to call, in order: primary vendor, backup vendor, then the owner or manager on call.
• Where food goes: which unit has spare capacity, and whether a second location or a rental unit is an option.
• Who decides what gets discarded, and under which written procedure. That decision should never wait for the technician.
• What to record: unit temperatures, food temperatures, times, and what was moved or discarded.
• Menu fallback: which items come off the menu if a unit or cooking station is down.
• When to contact the health department, such as loss of refrigeration capacity you can't cover, or a utility failure.

Onboarding vendors when nothing is broken

The easiest way to judge a vendor is to hire them for routine work first. Book a preventive visit, such as a refrigeration check or ice machine cleaning, and see whether they arrive when promised, explain what they find, and leave a readable invoice with readings. That visit also puts your equipment in their system before the emergency.

If a vendor offers a service agreement with priority response or scheduled maintenance, read what priority means in writing. Does it mean a response window or just a place in the queue? What's included, and what's billed extra? Whether an agreement pays off depends on your equipment count and how often you've had emergency calls. Your service log will tell you. Revisit the roster once a year. Vendors change staff, and a good technician leaving can matter more than a company name.
