When something else is needed
AHU cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
- Building management system faults

AHU cleaning for kitchens and businesses in Oakley
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for odours coming through the supply air and filters that are clogged or overdue, on filter sections, heating and cooling coils and internal panels.
Around a place like Oakley, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

The process
Every 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 half a day to a full day per unit, with large plant planned over several shifts. Around Oakley, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why deal with it now?
If people in a building in Oakley complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. It’s easy to lose track of when the work was last done on a quieter site.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Why us?
- A written report with photos after every visit
- Fixed quotes from a survey or pictures
- We diagnose before we treat
- Accredited under CHAS and SafeContractor, with ISO 9001

When to call us in Oakley
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
The symptoms we are asked about most are:
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
Wherever a school like Oakley CE Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before booking anyone

- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- How many systems or sites are involved
- The size of the system
- Working hours and out-of-hours timing
- Travel, parking and unloading
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call 0345 646 2711 or drop us a line.

How long does an AHU clean take?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so phone us on 0345 646 2711 or drop us a line to talk it through.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
