Horn Park AHU cleaning
Need AHU cleaning in Horn Park? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Plant that needs cleaning after a refit
- Odours coming through the supply air
- Leaves and litter drawn into the unit
The process
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. In Horn Park, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive

About our AHU cleaning in Horn Park
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you’re dealing with blocked condensate drains and slimy trays and units that have only ever had filter changes, we can put it right.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Horn Park, dust settles in the units and ducts year after year.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Questions from Horn Park
Can you work in Horn Park outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Horn Park keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Do you do school ventilation cleaning in Horn Park in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 41 schools and colleges on the FSA’s register within roughly a mile and a half of Horn Park, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Signs you need AHU cleaning in Horn Park
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
It’s time to book a visit if you see:
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
- Condensate trays that won’t empty
If you manage shops or offices close to Lee station, a TR19® Air inspection shows whether the ductwork needs cleaning.
What your quote should include
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a written report and pictures are included
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. With shared responsibility, good records help everyone.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Make sure condensate is draining away
- Keep filter changes on time and recorded
- Report water on the plant room floor
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

AHU cleaning around Horn Park
Food Standards Agency records list about 41 schools, colleges and universities and about 72 caring premises (care homes, nurseries and hospitals) registered as food businesses in and around Horn Park, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Horn Park, the closest hospital is Eltham Community Hospital, roughly 1.2 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. London plant rooms are often on roofs or in basements reached through occupied floors.
Healthcare buildings such as Eltham Community Hospital, about 1.2 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Horn Park, yours matters too.

What the work involves, part by part

Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- Travel, parking and unloading
- The condition we find in the survey
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
