AHU cleaning in Debden, done properly
Where a building in Debden has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers dampers and louvres, filter sections and internal panels, and common reasons people get in touch are air handling units with blocked filters and coils clogged with dust and debris.
For a building near Debden, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens on the day
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 a single shift for a typical unit, longer for large or heavily soiled ones. Tell us when your site near Debden is quiet and the visit will be booked for then.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Move anything stored near the system
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Don’t store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Part by part
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Debden questions
Can you get to a site in Debden?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can a school’s ventilation in Debden be done out of term time?
Yes. The holidays are the usual time for school work. With about 12 schools and colleges on the FSA’s register within roughly a mile and a half of Debden, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Is there a report after cleaning?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Common problems we fix in Debden
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
The symptoms we are asked about most include:
- Odours coming through the supply air
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
- Units needing a clean before a new tenant or handover
Healthcare ventilation, from large hospitals like Claybury Hospital (about 3 miles south) to small clinics, depends on clean filters, coils and ducts.

Ventilation in Debden buildings
Food Standards Agency records list about 12 schools, colleges and universities and about 18 care, childcare and hospital premises registered as food businesses within 1.5 miles or so of the middle of Debden. Busy, occupied buildings like these are where clean supply air matters most. Debden, about 13 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. About 3 miles south of Debden is Claybury Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Thomas Willingale Primary School and Nursery, ventilation cleaning is best booked for the holidays.

Leave it or put it right?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Light use slows the build-up but does not stop it.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
