Is Your Moncton Kitchen Exhaust Ready for Winter?

Winter in Greater Moncton is rough on restaurant equipment — and the exhaust system takes more of a beating than most owners realize. The rooftop fan sits out in the wind and snow all season. Grease behaves differently in the cold. And just as the weather turns, the holiday parties and office lunches pile on extra cooking.

If you run a kitchen in Moncton, Dieppe or Riverview, fall is the best time to get your exhaust system sorted. Here’s what to look at and why.

What Winter Does to Your Exhaust System

Grease hardens in cold ductwork

When the duct runs through an unheated space or up to the roof, cold air cools the grease on the inside walls. It turns thick and waxy and sticks harder. It doesn’t drain the way it does in summer, so it builds up faster in the upper duct and the fan.

The rooftop fan works harder

Fan belts stiffen and crack in the cold. Bearings that were already worn get louder. If the fan housing is caked with grease, the motor is pushing extra weight on top of that. A fan that limps through the fall can quit on a –20°C night in February.

Grease containment freezes and overflows

The grease box or absorbent pad on your rooftop fan catches the runoff. In winter it fills, freezes, and then overflows onto the roof when things thaw. That’s a fire hazard and it eats away at the roof membrane.

Snow and ice block access

Once the roof is covered in snow and ice, getting to the fan safely is harder and slower. Cleaning still has to happen — but doing the big clean before the snow flies makes the winter visits quicker and safer for everyone.

The holiday rush adds volume

November and December are the busiest months for a lot of Moncton kitchens. More cooking means more grease. If your last cleaning was back in the spring, you could be heading into the busiest stretch of the year with a system that’s already overdue.

Your Fall Exhaust Checklist

• Book a full hood cleaning before mid-November — hood, plenum, ductwork and rooftop fan, so you go into the holidays clean.
• Check the fan belt and bearings — replace a worn belt now rather than during a dinner service.
• Empty or replace the grease containment on the rooftop fan before it freezes.
• Make sure the fan has a hinge kit so it can tip open for cleaning without unbolting it on an icy roof.
• Look at your filters — bent or warped baffle filters let grease straight into the duct. Swap them out.
• Confirm your service sticker date and book your next visit on the calendar so it doesn’t slip during the busy season.
• Check your fire suppression tag — it should be inspected every six months, and fall is a good time to line it up with your hood cleaning.

What Your Staff Can Do Between Cleanings

Professional cleaning handles the parts you can’t reach. But your team can keep things in better shape day to day:

• Wash the baffle filters at least weekly — daily for fryer and grill lines.
• Wipe down the inside lip of the hood at close.
• Never run the cooking line with filters missing, even for a few minutes.
• Let a manager know if the fan sounds different or smoke starts hanging in the kitchen.
