AHU cleaning in Toothill
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Common call-outs are for debris and leaves in the fresh air intake and units that have only ever had filter changes, across dampers and louvres, heating and cooling coils and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Questions from Toothill
Will you come out to Toothill?
Yes, we work in villages as well as towns, and Toothill is covered. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Toothill?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Toothill needn’t be disturbed. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
Do you have insurance?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What else we do in Toothill
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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 they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
When it’s something else
Before you book, it helps to know what’s not included:
- Damaged coils beyond cleaning
- Building management system faults
- A system that’s undersized for the building
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think before booking.
Where we work
- Drain trays
- Filter sections
- Supply and extract fans
- Dampers and louvres

- Heating and cooling coils
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Out of sight is the usual reason a rural system goes too long without attention.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What you get with us
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Out-of-hours work and a 24/7 emergency line
- A written report with photos after each visit
- One contact for all your sites in London and the South East

How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. A quick note on how to find the site and where to park makes a visit to Toothill run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Clear the space around the work
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
Common problems we fix in Toothill
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Odours coming through the supply air
- Drain trays holding standing water
- Air handling units never cleaned inside
- Air handling units with blocked filters
For schools like The Mountbatten School, the holidays are the usual time to inspect and clean ventilation.

- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
