Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How we handle AHU cleaning in Graffham
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for units that have only ever had filter changes and units needing a clean before a new tenant or handover, on dampers and louvres, drain trays and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Questions from Graffham
Do you work overnight in Graffham?
Yes, out-of-hours work is a big part of what we do. That way a site in Graffham doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can a school’s ventilation in Graffham be done out of term time?
Yes, holiday work suits schools best. Around Graffham, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How long does it take to clean an air handling unit?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Keep inspection doors on the unit in good order
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
- Report musty smells from the vents straight away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.

Leave it or put it right?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. A planned visit to Graffham is easier to arrange than an emergency callout.
