How we handle AHU cleaning in Stanstead Abbotts
Our AHU cleans for sites in Stanstead Abbotts cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers heating and cooling coils, filter sections and drain trays, and the jobs we see most are air handling units never cleaned inside and debris and leaves in the fresh air intake.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows each 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.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
In-house cleaning or a specialist?
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.
Day-to-day cleaning is something your team can do: 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.
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Common problems we fix in Stanstead Abbotts
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Drain trays holding standing water
Classrooms and halls at schools such as The John Warner School are easiest to work in when pupils are away.

Why it’s worth doing now in Stanstead Abbotts
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Out of sight is the usual reason a rural system goes too long without attention.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

Stanstead Abbotts: your questions answered
Can you clean school ventilation in Stanstead Abbotts during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Stanstead Abbotts. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Stanstead Abbotts?
Yes, out-of-hours work is a big part of what we do. That way a site in Stanstead Abbotts does not have to lose a day’s trading. Your opening times are the first thing we ask for.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.
Can you price the work without visiting?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures are not enough, we will survey first.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711 or drop us a line.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Stanstead Abbotts, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
