AHU Cleaning in Woodgreen
We cover Woodgreen for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Odours coming through the supply air
How we handle AHU cleaning in Woodgreen
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers drain trays, filter sections and dampers and louvres, and people most often call us about rooms that smell stuffy when the system runs and fan sections that haven’t been cleaned in years.
In a village or hamlet like Woodgreen, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Woodgreen buildings and their air
We work across London and the South East, and Woodgreen is part of that. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Breamore Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. An inspection comes first for any ventilation job around Woodgreen, so the cleaning matches what’s there.
Woodgreen is in Hampshire. Woodgreen gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures.

Common questions in Woodgreen
Will you come out to Woodgreen?
Yes, we work in villages as well as towns, and Woodgreen is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Woodgreen after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Woodgreen keeps running as normal. Tell us your opening hours when you ask for a quote.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
When something else is needed
Before you book, it helps to know what’s not included:
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
If you’re not sure, just phone us on 0345 646 2711 or email us and we will give you a straight answer before you book.
What the work covers
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
- Supply and extract fans
- Filter sections
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Woodgreen.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Related advice
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Don’t ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Report water on the plant room floor
- Make sure condensate is draining away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Why it’s worth doing now in Woodgreen
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 Woodgreen simpler. A fault that closes a site in a village like Woodgreen affects everyone who depends on it.

What else we do in Woodgreen
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
How we price AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- How big the system is
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The site address and the type of premises
- The times we could work without disrupting the site
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
For a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
