How we handle AHU cleaning in Wyatt's Green
Where a building in Wyatt's Green has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you are dealing with plant that needs cleaning after a refit and units that have only ever had filter changes, we can help.
Work in a small place like Wyatt's Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What AHU cleaning can’t fix
In fairness, there are a few things this work won’t fix:
- A system that’s undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
If you’re not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer.
Parts of the system we cover
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Drain trays
What we do, step by step
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a village like Wyatt's Green are booked in advance, at a time that suits whoever runs the site.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Arrange a key holder or contact on site
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
Ask for a quote
To get a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Advice
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Book the next check in line with the report
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents straight away
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Why deal with it now?
If people in a building in Wyatt's Green complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Out of sight is the usual reason a rural system goes too long without attention.
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.

Wyatt's Green: your questions answered
Can you work in Wyatt's Green outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Wyatt's Green keeps running as normal. When you call us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you cover smaller places like Wyatt's Green?
Yes. Villages and rural sites across the South East are part of our work, Wyatt's Green included. Just mention lanes, gates or anything else about the site when you book.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
How much does AHU cleaning cost?
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 any work starts.
How long does it take to clean an air handling unit?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call 0345 646 2711 or drop us a line.

Do you need AHU cleaning in Wyatt's Green?
Whatever surrounds a building in Wyatt's Green, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Clients normally contact us after spotting one of these:
- Dirty fans and fan housings
- Air handling units due a clean after building work
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
Wherever a school like Doddinghurst Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
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. Reaching it takes a specialist with the right equipment.
