Woodham AHU cleaning
AHU cleaning across Woodham and nearby, timed so the site keeps working and signed off in writing with photos.
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
Between visits
To keep the system working properly between visits:
- Do not ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
AHU cleaning in Woodham, done properly
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. The work covers drain trays, heating and cooling coils and filter sections, and people most often call us about units that have only ever had filter changes and dust built up on fan impellers.
In a smaller place like Woodham, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the quote in Woodham
The diagnosis comes before the price. We look at:
- How easy every part is to reach
- Working hours and out-of-hours timing
- How big the system is
- Whether several sites go on one quote
Putting the work off seldom saves money. 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, call us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Where the site is and what kind of site it is
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Signs you need AHU cleaning in Woodham
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Common reasons sites call us are:
- Debris and leaves in the fresh air intake
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
If you manage shops or offices close to West Byfleet station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Why act early in Woodham
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. It’s easy to lose track of when the work was last done on a quieter site.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

- Fixed quotes from a survey or photos
- Fully insured

Questions from Woodham
Do you work overnight in Woodham?
Yes, out-of-hours work is a big part of what we do. It means the site in Woodham keeps running as normal. Let us know the hours you are closed and we will book within them.
Can ventilation in schools around Woodham be cleaned out of term?
Yes, and it’s the easiest time to do it. Around Woodham, the Food Standards Agency lists about 17 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
How much does AHU cleaning cost in Woodham?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How long does it take to clean an air handling unit?
The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, so phone us on 0345 646 2711 or drop us a line to talk it through.
What if parts of the system can’t be reached?
We record them 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.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Tell us about any gates, ladders or locked plant areas at your site near Woodham when you book.

- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
