AHU Cleaning in Woburn
AHU cleaning for Woburn, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Air handling units due a clean after building work
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
The process
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Woburn.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use

AHU cleaning for kitchens and businesses in Woburn
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. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for air handling units with blocked filters and leaves and litter drawn into the unit, on filter sections, drain trays and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. 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.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Staff cleaning versus specialist work
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. That is our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- Book the next check in line with the report
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Your questions about AHU cleaning in Woburn
Do you work overnight in Woburn?
Yes, evening, overnight and weekend work is normal for us. It means the site in Woburn keeps running as normal. When you call us on 0345 646 2711, or send details by email, mention when the site is quiet.
Do you cover smaller places like Woburn?
Yes. Villages and rural sites across the South East are part of our work, Woburn included. Let us know about access, parking and anything unusual about getting there when you book.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What if parts of the system cannot be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What a clean will not put right
A few issues sit outside what this work can do:
- A system that is undersized for the building
- Dirty ducts beyond the unit itself
- Problems with the unit’s controls or sensors
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer.

- Units that have only ever had filter changes
- Blocked condensate drains and slimy trays
