How we handle AHU cleaning in Oakfield
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Common call-outs are for dirty fans and fan housings and dirty filters cutting the airflow, on internal panels, supply and extract fans and heating and cooling coils.
For a building near Oakfield, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the journey to Oakfield and bring what the job is likely to need.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
Advice
When something else is needed
It’s worth knowing the limits before booking:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
If you’re not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.

Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Oakfield simpler. It’s better to plan the work at a site near Oakfield than wait for a failure.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.

Your questions about AHU cleaning in Oakfield
Can you get to a site in Oakfield?
Yes, we work in villages as well as towns, and Oakfield is covered. Just mention lanes, gates or anything else about the site when you book.
Do you do school ventilation cleaning in Oakfield in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Oakfield. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we will fit the work in.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How much does AHU cleaning cost in Oakfield?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
AHU cleaning around Oakfield
Going by the FSA’s register, there are about 12 schools, colleges and universities, about 21 care, childcare and hospital premises and about 9 hotels, B&Bs and guest houses serving food across Oakfield and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Gosport War Memorial Hospital is the nearest hospital, about 5 miles north of Oakfield. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Wherever a school like Dover Park Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near Ryde St Johns Road station, its supply ductwork can gather dust for years before anyone looks inside.

Signs you need AHU cleaning in Oakfield
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Air handling units never cleaned inside
- Units needing a clean before a new tenant or handover
If you run a surgery, dental practice or care home near Oakfield, clean ventilation matters as much to you as to a hospital like Gosport War Memorial Hospital (about 5 miles north).
