How we handle AHU cleaning in Stotfold Common
We clean air handling units for buildings in Stotfold Common and across Hertfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with coils clogged with dust and debris and units needing a clean before a new tenant or handover, we can put it right, from filter sections, supply and extract fans and dampers and louvres onwards.
Somewhere as small as Stotfold Common, ducted ventilation is normally 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.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common questions in Stotfold Common
Do you do school ventilation cleaning in Stotfold Common in the summer holidays?
Yes, holiday work suits schools best. Around Stotfold Common, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work at weekends in Stotfold Common?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
What information do you need?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Can you price the work without visiting?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we normally come back within one working day. If pictures aren’t enough, we will survey first.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Store the TR19 paperwork where auditors can find it
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Report water on the plant room floor
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
If your staff spot something 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’ll take a look and send you a fixed quote.
What AHU cleaning looks like in Stotfold Common
Food Standards Agency records list about 3 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) registered as food businesses within 1.5 miles or so of the middle of Stotfold Common. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.9 miles south of Stotfold Common is Fairfield Hospital, the nearest hospital.

How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. For a village or hamlet like Stotfold Common, tell us about narrow lanes, gates and parking when you book.
- 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.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
When something else is needed
AHU cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:
- Dirty ducts beyond the unit itself
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.
What we work on in Stotfold Common

- Heating and cooling coils
- Drain trays

What we’re called out for in Stotfold Common
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Units needing a clean before a new tenant or handover
If you run a surgery, dental practice or care home near Stotfold Common, clean ventilation matters as much to you as to a hospital like Fairfield Hospital (about 1.9 miles south).
