How we handle AHU cleaning in Jersey Farm
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. The work covers heating and cooling coils, supply and extract fans and filter sections, and the jobs we see most are blocked condensate drains and slimy trays and fan sections that haven’t been cleaned in years.
For a building near Jersey Farm, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What the work involves, part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Ventilation in Jersey Farm buildings
The FSA’s food hygiene register lists about 11 schools, colleges and universities and about 8 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within roughly a mile and a half of the centre of Jersey Farm. Busy, occupied buildings like these are where clean supply air matters most. About 1.5 miles south of Jersey Farm is Hill End Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Jersey Farm is about 21 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
If you run a surgery, dental practice or care home near Jersey Farm, clean ventilation matters as much to you as to a hospital like Hill End Hospital (about 1.5 miles south).

When to call us in Jersey Farm
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
- Condensate trays that will not empty
- Dirty fans and fan housings
Wherever a school like Skyswood Primary & Nursery School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Your questions about AHU cleaning in Jersey Farm
Can a school’s ventilation in Jersey Farm be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 11 schools, colleges and universities with registered kitchens within about a mile and a half of Jersey Farm. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
Will you come out to Jersey Farm?
Yes. Villages and rural sites across the South East are part of our work, Jersey Farm included. Photos of the system and directions to the site help us plan the visit.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Can you clean the AHU out of hours?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think before you book.
What the work covers
- Filter sections
- Internal panels
- Drain trays

What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Getting to the system matters more than parking in a place like Jersey Farm, so let us know how to reach it.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Why it’s worth doing now in Jersey Farm
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Booking now means the visit to Jersey Farm is planned around you, not forced by a breakdown.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
