Allhallows AHU cleaning
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for businesses, landlords and public buildings in Allhallows. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Allhallows knowing what to expect.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions

About our AHU cleaning in Allhallows
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for dirty filters cutting the airflow and stale or musty smells from the ventilation, on internal panels, dampers and louvres and drain trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Fixed quotes for AHU cleaning in Allhallows
We quote each job individually. This is what makes a difference:
- The size of the system
- Whether we need access equipment or extra panels
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
Helping us quote
We can often survey from photos. The most useful are:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see

Why it’s worth doing now in Allhallows
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Allhallows simpler. 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, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Why book with us
- Fixed quotes, typically within one working day
- We are fully insured
- Trading since 2009
- We diagnose before we treat
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Common problems we fix in Allhallows
Whatever surrounds a building in Allhallows, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
It’s time to book a visit if you see:
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
Wherever a school like Allhallows Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Allhallows: your questions answered
Is Allhallows within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Allhallows included. Let us know about access, parking and anything unusual about getting there when you book.

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Allhallows needn’t be disturbed. When you call 0345 646 2711, or send details by email, mention when the site is quiet.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call us on 0345 646 2711 or drop us a line.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
How long will the unit be out of action?
The work takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, so give us a ring on 0345 646 2711 or email us to talk it through.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
