AHU cleaning for kitchens and businesses in Walhampton
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you are dealing with rooms that smell stuffy when the system runs and coils clogged with dust and debris, we can help.
Somewhere as small as Walhampton, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

AHU cleaning around Walhampton
There are about 9 schools, colleges and universities, about 14 caring premises (care homes, nurseries and hospitals) and about 4 hotels and guest houses on the FSA’s food hygiene register within about 1.5 miles of central Walhampton. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 0.8 miles north-west of Walhampton is Lymington New Forest Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare buildings such as Lymington New Forest Hospital, about 0.8 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Walhampton, yours matters too. School buildings such as Lymington Church of England Infant School are usually done in the holidays, so classrooms aren’t disturbed.

What a clean won’t put right
Some problems need a different service or another trade:
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly before booking.
Parts of the system we cover
- Supply and extract fans
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
- Dampers and louvres
Between visits
Once we’ve finished, these simple steps help:
- Flag stale or damp smells in the supply air
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Your questions about AHU cleaning in Walhampton
Do you work overnight in Walhampton?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Walhampton needn’t be disturbed. Your opening times are the first thing we ask for.
Can ventilation in schools around Walhampton be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 9 schools and colleges on the FSA’s register within roughly a mile and a half of Walhampton, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is Walhampton in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Walhampton.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What we are called out for in Walhampton
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
These are the problems we see most often:
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
If you manage offices or shops near Lymington Town station, their ventilation can be inspected and cleaned out of hours.
What your quote should include
- What happens if part of the system cannot be accessed
- Whether the work can be done while the site is closed
- When the next visit should be, and why
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Equipment tucked in a roof space or outbuilding near Walhampton rarely gets looked at unless someone books it.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What you get with us
- Survey first, then a fixed quote
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001
- Each visit written up, with pictures

What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
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.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send pictures, we can arrive in Walhampton knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Arrange a key holder or contact on site
- Clear loose items from the work area
- Tell us where we can park and unload
How to get a quote
