Building a preventive maintenance schedule for a single site

Multi-site operators run maintenance programs because they have someone whose job it is. Single-site operators usually run reaction, because every hour of the day already belongs to something else. The gap between the two is not effort. It is a one-page schedule and an asset list, both of which take an afternoon to build and then run themselves.

Start with the asset register, not the calendar

You cannot schedule work on equipment you cannot name. Walk the building with a phone and photograph the data plate of everything that can fail expensively:

• Rooftop units or split systems, one entry each, with tonnage, refrigerant, filter sizes and quantity
• Walk-in cooler and freezer condensing units and evaporators
• Reach-in coolers, prep tables and display cases
• Ice machine, with its water filter model and last change date
• Water heater, with capacity, recovery rate and the mixing valve setting
• Grease interceptor, with its size, its location and the date it was last pumped
• Exhaust hood, the fan on the roof, and the fire suppression system with the date on its tag
• Fryers, ranges, ovens, dishwasher, and the chemical vendor who services it
• Backflow assembly, floor drains, sump and lift pumps
• Electrical panels, with a photograph of the schedule inside each door
• Interior, exterior and sign lighting, with lamp types and counts
• POS terminals, router, switch, card readers and the UPS with its install date
• Recorder and camera count
• Door closers, exterior locks, and the walk-in door hardware

Put it in one spreadsheet with columns for make, model, serial, install year, service vendor and last service date. That sheet is what makes a 5 PM phone call short.

Four buckets, four owners

Daily, five minutes, opening manager. Walk the kitchen, the back hall and the lot. Look for water where there should be none, listen for anything cycling that should be steady, read every cooler and freezer against the 41 F cold-holding limit and log the number rather than a tick, confirm hot water at the handwash sink, and check that the exterior and sign lighting came on last night.

Monthly, 45 minutes, manager. Change or check HVAC filters and date the frame. Pour water down every floor drain, including the ones under equipment nobody moves. Clean condenser coils on the reach-ins and the ice machine. Pull the last 30 days of alarms off the refrigeration controller and close out anything that was silenced rather than fixed. Pull three minutes of camera footage from the previous day and confirm it exports. Test emergency lighting and exit signs. Photograph the restroom, the interceptor lid and the back hall for the file.

Quarterly, contracted. Hood and duct cleaning on the interval NFPA 96 sets for your operation, which is by cooking volume and not by the calendar: monthly for solid fuel, quarterly for high-volume work like charbroiling or a 24 hour line, semiannually for everything ordinary, annually for genuinely low volume. Find your own row, book it, and keep the certificate where the fire inspector will ask for it. Refrigeration checks on the walk-ins in the two months before summer and before winter. Grease interceptor pumped, on your local ordinance or once grease and solids reach a quarter of the tank's wetted depth, which you measure rather than guess. Coffee and beverage equipment descaled. Camera domes cleaned. Pressure wash the entry and the dumpster pad.

Annual, contracted plus compliance. HVAC cooling check in April and heating check in October. Kitchen fire suppression inspection, which is a six month interval, so budget two visits and not one. Backflow assembly test. Fire extinguisher tagging by a licensed company, plus your own monthly visual checks recorded on the tag. Main line snake. Water heater flush and anode check. Dryer vent cleaning if you launder on site. Electrical panel thermal scan every second year in a building over 20 years old.

Sequence it so the spend does not stack

The failure mode to design out is a program where six annual services all land in the same month. That is the default rather than bad luck: each contract is set up in the week somebody finally sits down to arrange it, and every one of them then renews on that same anniversary forever. Spread them:

1. 1January. Records catch-up, insurance, health permit and business license renewals, and a read of last year's repair ledger.
2. 2February. Refrigeration pre-summer visit: walk-in, freezer, reach-ins, prep tables and display cases, coils cleaned on all of it.
3. 3March. Main line snake, interceptor pumped and measured, plumbing walk, water heater flush, pressure wash the entry.
4. 4April. HVAC cooling check, economizer function, filters for the season.
5. 5May. Ice machine descale and water filters, before the season rather than during it.
6. 6June. Lighting and camera audit after dark, when you can actually see what is out. Lot poles and the sign included.
7. 7July. Nothing scheduled. Keep capacity free, because this is when things break.
8. 8August. Cooking equipment service: fryers, ranges, ovens, dishwasher, hood fan bearings and belts. Book it into your slowest week.
9. 9September. Snow and de-icing contract signed where your market needs one, winter kit bought, roof walked before the wet season.
10. 10October. HVAC heating check and combustion readings.
11. 11November. Freeze protection: heat tape, exposed lines, hose bibs, the water heater and anything sitting in an unheated back hall.
12. 12December. Next year's budget built off the repair ledger, and any multi-year compliance item that lands in this cycle year.

Leave July and late December empty on purpose. A program with no slack turns into a program that gets cancelled.

What it costs, and what it saves

Do not take an annual figure off a page like this one. Price your own program from the asset register: two HVAC visits, hood cleaning at your NFPA interval, two refrigeration visits, the interceptor on its ordinance interval, a backflow test, extinguisher tagging, two fire suppression inspections and a main line snake. Put a market range against each line, add them up, and set that total beside last year's repair ledger. A number you built from your own equipment is one you can defend to yourself in January. A percentage of sales is not.

The saving comes from three places, and only one of them is obvious.

The obvious one: parts replaced on schedule cost a fraction of the same parts replaced after they take something else out. A $40 contactor versus a $2,400 compressor is the standard example, and it is standard because it happens constantly.

The second: emergency premiums disappear. After-hours labor runs 1.5x with a $150 to $300 callout, and a planned visit does not carry either.

The third, and the biggest over five years: equipment life. Maintained rooftop units, walk-in systems and ice machines run years longer than neglected ones, which pushes capital replacement further out and lets you choose the month you spend it.

Measure two things and the program manages itself

Track downtime hours per asset and repeat visits per asset. Any piece of equipment with three service calls in twelve months goes on a watch list, and anything on the watch list two years running goes on the replacement plan with a quote attached. Ask for three quotes on anything above $1,500.

That is the whole system: a list of what you own, four buckets of work, a 12-month sequence and two metrics. It fits on two pages and it is the difference between a site that spends money on purpose and one that spends it on Saturdays.
