AHU cleaning in Bow
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with debris and leaves in the fresh air intake and stale or musty smells from the ventilation, we can put it right, from drain trays, supply and extract fans and dampers and louvres onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Bow is often done in the evening or at weekends. Loading and parking are planned with the building first.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Bow.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
- Clear the space around the work

Your questions about AHU cleaning in Bow
Can ventilation in schools around Bow be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 65 schools and colleges with food registrations within roughly a mile and a half of Bow. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How do you handle parking and loading in Bow?
Tell us where a van can stop near your site in Bow, and about any building rules on loading. Much of our London work is done overnight, which helps.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
- Stick to the filter change plan
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
When something else is needed
Before you book, it helps to know what’s not included:
- Dirty ducts beyond the unit itself
- Problems with the unit’s controls or sensors
- Coils that are corroded or leaking and need replacing
If you are not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer before booking.
Parts of the system we cover
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
- Internal panels
What your team can do, and what needs us
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.
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.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
What happens if it’s left?
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 Bow simpler. Planning ahead in Bow lets you pick a quiet night rather than lose a busy one.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

Ventilation in Bow buildings
There are about 65 schools, colleges and universities, about 45 caring premises (care homes, nurseries and hospitals) and about 17 hotels and B&Bs on the FSA’s food hygiene register within 1.5 miles or so of the middle of Bow. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Ventilation cleaning in London buildings is typically planned for evenings or weekends. Bow’s nearest hospital, St Clement's Hospital, is about within half a mile south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
For workplaces around Hackney Wick station with mechanical ventilation, cleaning can be done in the evening or at weekends. For schools like Old Ford Primary - A Paradigm Academy, the holidays are the usual time to inspect and clean ventilation.

Signs you need AHU cleaning in Bow
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Common reasons sites call us include:
- Leaves and litter drawn into the unit
- Dust-coated heating and cooling coils
- Air handling units with blocked filters
- Drain trays holding standing water
Healthcare buildings such as St Clement's Hospital, about less than half a mile south, depend on their ventilation; if you manage a surgery, clinic or care home near Bow, yours matters too.
