A Practical Maintenance Checklist for Commercial Kitchen Hoods

Hood systems last longer and stay easier to clean when someone is paying attention between full services. This checklist is not a maintenance contract — it is a practical way to split hood care between what your team can see day to day and what belongs to a professional cleaning and maintenance visit.

Why preventive hood maintenance matters

A hood system that is only cleaned when it looks bad is usually cleaned too late. Grease collects gradually on canopy surfaces, filters and accessible exhaust components; by the time it is obvious, the next cleaning is more difficult, and the system may be pulling less air than the kitchen expects.

A simple routine — watching visible condition between visits, and booking cleaning and maintenance at sensible intervals — catches most of the risk without turning your staff into technicians.

What staff can safely monitor between visits

These are glance-level checks. Note anything unusual and pass it to whoever manages the booking:

• Filters still sitting correctly in their frames, with nothing sagging out of place.
• Canopy surfaces showing visible grease film or drips forming below.
• Airflow at the cooking line: nothing hanging that struggles to draw smoke away.
• Lights and the hood area staying clean enough for shift-to-shift wiping where allowed.
• New noises or smells that started with the exhaust running.

Reasons to book a provider

Book a cleaning or maintenance visit when any of the following shows up, regardless of the calendar:

• Visible buildup on surfaces or around the hood area that routine wiping is not addressing.
• Persistent odours or grease deposits appearing near the hood.
• Filters that load up unusually quickly or no longer seat properly.
• Airflow changes that bother the cooking line.
• A long gap since the last documented service, or no service records at all.

Questions to ask a hood cleaning and maintenance provider

Before booking, ask the questions that prevent disagreement later:

• Which components are included in the cleaning and which are excluded?
• How is access handled for fans, roof points and duct sections?
• Is maintenance between cleanings offered, and what does it cover?
• What documentation is provided after each visit?
• What interval do they recommend for this kitchen, and what observations is it based on?

Documenting service and findings

A maintenance rhythm only works if the records back it up. Keep a simple log — a spreadsheet or notebook is fine — with four fields per visit:

• Date of the visit.
• Service type — cleaning, maintenance check or repair follow-up.
• Observations — anything the provider noted, including access limits.
• Next step — the recommended interval or outstanding item.

Grease Shields provides service documentation after each cleaning or maintenance visit; a copy of it belongs in the same place as your own notes.

Arranging an assessment or maintenance visit

If your hood system has no recent records, or any of the booking reasons above apply, the first step is an assessment rather than a fixed plan. Grease Shields cleans and maintains hood, canopy, filter and accessible exhaust components in St. John's and across the Island of Newfoundland — see the hood cleaning and maintenance service or request a quote.
