AHU cleaning in Raynes Park
If the units serving a building in Raynes Park have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers drain trays, heating and cooling coils and dampers and louvres, and common reasons people get in touch are dust built up on fan impellers and rooms that smell stuffy when the system runs.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Raynes Park is typically planned out of hours. Loading and parking are planned with the building first.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.

Common problems we fix in Raynes Park
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, a little more each month.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
Classrooms and halls at schools such as West Wimbledon Primary School are easiest to work in when pupils are away.

Common questions in Raynes Park
Can you come to Raynes Park after we close?
Yes, we can come after you close and finish before you open. It means the site in Raynes Park keeps running as normal. Your opening times are the first thing we ask for.
What do you need to know about parking in Raynes Park?
Tell us where a van can stop near your site in Raynes Park, and about any building rules on loading. Much of our London work is done overnight, which helps.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Do you need to switch the unit off?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away 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. Loading bays, visitor permits and roof access are the first things we ask about for a site in Raynes Park.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down

Advice
When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before you book.
What we work on in Raynes Park
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
- Drain trays
- Filter sections
- Internal panels
Aftercare tips
Here’s the after-treatment advice, in brief:
- Clear leaves and litter away from the intake
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Make sure condensate is draining away
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What affects the quote in Raynes Park
You’ll get a fixed price before any work starts. It takes into account:
- A single visit or a regular plan
- The number of sites or systems
- The condition we find in the survey
- How easy every part is to reach
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 play a part.
Asking for a quote
What to send for a quote:
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
- A few general shots of the system
Some systems can be priced from photos; others need a survey. 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.

Hospitals such as Atkinson Morley Hospital (about 1 mile north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Raynes Park are no different.

Different parts, different methods
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
