How we handle AHU cleaning in Stanwell Moor
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for air handling units with blocked filters and air handling units due a clean after building work, across heating and cooling coils, supply and extract fans and drain trays.
Somewhere as small as Stanwell Moor, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Common questions in Stanwell Moor
Can you clean school ventilation in Stanwell Moor during the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Stanwell Moor. Send us your term dates when you phone us on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Can you work in Stanwell Moor outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in Stanwell Moor does not have to lose a day’s trading. Just give us a ring on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
What should I send you?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What if parts of the system can’t be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How we price AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- What state the system is in
- One-off work versus a regular cycle
- The times the site is available
- Any permits to work or inductions
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.
Asking for a quote
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Your last certificate, test record or report
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
AHU cleaning in Stanwell Moor: local notes
The FSA’s food hygiene register lists about 4 caring premises (care homes, nurseries and hospitals) and about 5 hotels, B&Bs and guest houses with registered kitchens or food service in and around Stanwell Moor, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Stanwell Moor’s nearest hospital, Ashford Hospital, is about 2 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 18 miles out from central London, Stanwell Moor is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
For schools like Town Farm Primary School & Nursery, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Stanwell Moor, clean ventilation matters as much to you as to a hospital like Ashford Hospital (about 2 miles south-east).

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Don’t store bins or materials near the intake
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

When it’s something else
To be straight with you, there are a few things this work will not fix:
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
- A system that’s undersized for the building
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer.
Where we work

Why act early in Stanwell Moor
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. It’s simpler to plan the work at Stanwell Moor now than to arrange it in a hurry later.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

The process
Your trading hours come first. 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 work takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Stanwell Moor are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
When to call us in Stanwell Moor
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Units that have only ever had filter changes
- Air handling units due a clean after building work
- Drain trays holding standing water
- Dirty fans and fan housings
Workplaces around Heathrow Terminal 5 Rail station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- What paperwork you get at the end
- Whether the work can be done while the site is closed
- Whether they recommend a next date
