Every store has slow weeks. Use them for the repairs you'd hate to need in the rush.

It's different for every concept. A lakefront restaurant slows down in winter. A downtown lunch spot slows in late summer and over the holidays. Many stores have a slow stretch in January and February.

Look at last year's sales by week for each store. The lowest weeks are your repair window.

Refrigeration. Condenser coils cleaned, gaskets replaced, thermostats checked, refrigerant pressures checked. A walk-in that has to be emptied for work is much easier to handle when stock is low.

Ice machines. Descaling and sanitizing take a machine offline for hours. Do it before the busy season, so it's clean for the peak.

Steamers and combi ovens. Deep descaling. Hard water builds scale fast, and the busy season is when it hurts most.

Cook line. Burners cleaned and adjusted, thermostats checked on ovens and fryers, worn gas hoses and door gaskets replaced.

HVAC. Cooling checked in spring, heating checked in fall. Both before the season starts, not during it.

Every service visit turns up parts that are wearing out but still work: a worn belt, a cracked gasket, a contactor with burnt contacts. It's tempting to let them run.

The slow season is when to replace them. You choose the day, the store keeps running, and the part doesn't fail mid-rush. Ask your technician to list what's wearing out after each visit, so you can plan for it.

For a restaurant group, don't do every store the same week. Stagger the work so each store's slow weeks get their own visit. Book it a month or two ahead, since every restaurant in the area wants the same quiet weeks.

Keep a list for each store of what was done and what's next. It becomes next year's plan.

While equipment is offline, deep-clean behind and under it. Pull line equipment out on its casters and clean the floor and wall. Clean the hood filters and the grease troughs. It's easier with the store quiet.
