AHU cleaning for kitchens and businesses in Wimbledon Chase
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. If you have intake sections clogged with outdoor debris and air handling units with blocked filters, we can put it right, from internal panels, filter sections and dampers and louvres onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Wimbledon Chase, as elsewhere, cleaning starts with an inspection of what’s there.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- File each AHU report in the maintenance log
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. In Wimbledon Chase, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area 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.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Mention any parking or loading restrictions
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then ring 0345 646 2711 or send us an email.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
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.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

What we are called out for in Wimbledon Chase
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Clients normally contact us when they notice one of these:
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
- Dirty coils holding back the airflow
If you manage a school such as Wimbledon Chase Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- When they can work, and whether that is outside your opening hours
- Proof of insurance
- How VAT is shown on the quote
- Whether the whole system is included, or only the parts that are easy to reach
What AHU cleaning can’t fix
We will not sell you work that does not address the problem, so here are the limits:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.
What the work covers
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Filter sections
- Internal panels
- Dampers and louvres

Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Wimbledon Chase’s nearest hospital, Atkinson Morley Hospital, is about 1.2 miles north-west.
