How we handle AHU cleaning in Coolham
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. The work covers drain trays, filter sections and heating and cooling coils, and common reasons people get in touch are intake sections clogged with outdoor debris and blocked condensate drains and slimy trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Between visits
Results last longer with the right care. We suggest:
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
- Keep inspection doors on the unit in good order
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Why act early in Coolham
If people in a building in Coolham complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. With notice, the visit to Coolham can be fitted around your bookings and events.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

- Accredited under CHAS and SafeContractor, with ISO 9001
- Each visit written up, with pictures

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What we are called out for in Coolham
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Look out for these warning signs:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Air handling units never cleaned inside
- Filters that are clogged or overdue
Classrooms and halls at schools such as William Penn School are easiest to work in when pupils are away.

FAQs for Coolham
Do you offer AHU cleaning in Coolham?
Yes, we work in Coolham and the places around it. A fixed quote typically follows within one working day of the survey details.
Do you cover smaller places like Coolham?
Yes. Coolham is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you work evenings or weekends?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
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. Then phone us on 0345 646 2711 or drop us a line.

It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave.

- Filters, coils, fan section and casing are cleaned in turn.
