What happens on the day
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Potter's Forstal are booked in advance, at a time that suits whoever runs the site.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload

Advice
AHU cleaning for kitchens and businesses in Potter's Forstal
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, dampers and louvres and internal panels, and common reasons people get in touch are filters that are clogged or overdue and air handling units never cleaned inside.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Plan the next inspection before the last report gets filed away
- Do not store bins or materials near the intake
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

Potter's Forstal: your questions answered
Can you come to Potter's Forstal after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you cover smaller places like Potter's Forstal?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Somewhere as small as Potter's Forstal, losing a kitchen or building to a fault is felt by everyone who uses it.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before work begins.

What we’re called out for in Potter's Forstal
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Signs it’s time to call us include:
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
Wherever a school like Egerton Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

- Exactly which parts of the system are covered
- When they can work, and whether that’s outside your opening hours
- What paperwork you get at the end
