What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
About our AHU cleaning in Bovingdon Green
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have stale or musty smells from the ventilation and units that have only ever had filter changes, we can put it right.
In a village or hamlet like Bovingdon Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Bovingdon Green questions
Can you clean school ventilation in Bovingdon Green during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Bovingdon Green. Just phone us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Is Bovingdon Green within the area you cover?
Yes, Bovingdon Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you clean the AHU out of hours?
Yes, wherever it helps the building. We plan the shutdown window with you.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Honest limits
In fairness, there are a few things this work won’t fix:
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.
What we work on in Bovingdon Green
- Dampers and louvres
- Drain trays
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Internal panels
Between visits
So the system stays in good health:
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Make sure the unit’s access doors open easily
- Keep filter changes on time and recorded
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Bovingdon Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so you can decide on any repairs.

What else we do in Bovingdon Green
Leave it or put it right?
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. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like Bovingdon Green affects everyone who depends on it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Common problems we fix in Bovingdon Green
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
School buildings such as Spinfield School are usually done in the holidays, so classrooms are not disturbed.
