Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
AHU cleaning in Setley
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. We are often asked to deal with dust built up on fan impellers and units that have only ever had filter changes, on supply and extract fans, dampers and louvres and filter sections.
For a building in or near Setley, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy
So the system stays in good health:
- Diary the inspection date recommended in the report
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Report musty smells from the vents straight away
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. Planning a trip to Setley ahead is easier for everyone than a rushed one.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Questions from Setley
Do you cover smaller places like Setley?
Yes. Setley is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can you work in Setley outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Setley doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How long does an AHU clean take?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, and you can call us on 0345 646 2711 or drop us a line to plan it.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Are you fully insured?
Yes. We’re fully insured, and we can share the details when you need them.

What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Setley, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Mention any parking or loading restrictions
- Dig out any earlier paperwork for the system
- Move anything stored near the system
