Winter-Proofing Your Restaurant Equipment: What to Inspect Before It Gets Cold

Cold weather is rough on commercial kitchens. Even if the temperature inside stays warm, your equipment, gas lines, and plumbing are still affected by what happens outdoors. A few quick checks in late Fall can save you from the kind of mid-January emergency that shuts a kitchen down on a Saturday night.

Here’s what every restaurant should inspect before winter hits.

1. Make Sure Your Walk-In Is Ready for Temperature Drop

Walk-ins work harder in the winter because the air outside the box changes how the unit cycles.

Check for:

• Cracked or brittle door gaskets

• Ice buildup on the evaporator

• Fans making unusual noise

• Door sweeps that don’t fully seal

  
  

A walk-in that loses cold air in the winter will freeze up faster than in summer, because the unit short-cycles to compensate. That leads to coil failures and expensive service calls.

2. Protect Your Gas-Fired Equipment

Colder temps impact combustion. If you haven’t cleaned or tuned gas equipment since spring, winter is when problems show up.

Inspect:

• Gas lines for leaks

• Burners for soot or orange/yellow flames

• Pilots that won’t stay lit

• Heat exchangers and venting

  
  

Uneven heating in convection ovens, slow recovery on fryers, or inconsistent grill temps are all early warnings you shouldn’t ignore.

3. Check Your Ice Machines Before They Freeze

Ice machines don’t like cold air, and they especially don’t like sitting near drafty doors or uninsulated exterior walls.

Look for:

• Slow harvest cycles

• Scale on the evaporator plate

• Clogged water lines affected by cold temps

• Filters overdue for replacement

  
  

A single clogged line can put you out of ice during peak hours — which is the last thing a restaurant needs in winter.

4. Don’t Forget Your Water Lines

Freezing pipes are everyone’s nightmare, but restaurants get hit harder because the water demands are constant.

Inspect:

• All exposed or exterior-facing water lines

• Sink lines by drafty windows

• Lines feeding ice machines and dishwashers

• Mop sink areas, which are usually under-insulated

  
  

If you can see daylight under a door or feel a cold draft in a prep area, that’s a risk point.

5. Prep Your Dish Machine for Winter Workloads

Holiday traffic, catering, and large parties push dish machines to their limit.

Make sure:

• Booster heaters are hitting the correct rinse temperatures

• Rinse arms rotate freely

• Detergent and rinse pumps aren’t clogged

• Door seals still have flexibility

  
  

Winter breakdowns usually trace back to poor flow or brittle seals — both easy fixes if you catch them early.

6. Give Your Hood and Ventilation System Some Attention

Cold air affects draft, and a weak draft affects everything in the kitchen.

Inspect:

• Fan motors

• Belts for cracking

• Filters overdue for cleaning

• Louvers that don’t open/close fully

  
  

Poor draft = uneven cooking temps, smoke where it shouldn’t be, and complaints piling up.

7. Test Your Emergency Heat Sources

If your kitchen uses any units that rely on ambient temperature — like proofers, holding cabinets, or dough warmers — winter is when they struggle.

Look for:

• Slow warm-up times

• Drying out food

• Hot spots or uneven warmth

  
  

Cold kitchens exaggerate equipment weaknesses.

A Winter Tune-Up Now Beats an Emergency Call Later

Most equipment failures in winter aren’t “winter issues” — they’re maintenance issues that the cold finally exposes.

If you want a simple rule of thumb: If it uses water, gas, or airflow, it needs a winter check.
