How we handle AHU cleaning in Nuneham Courtenay
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers internal panels, heating and cooling coils and drain trays, and common reasons people get in touch are plant that has been serviced but not cleaned and blocked condensate drains and slimy trays.
For a building in or near Nuneham Courtenay, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like Nuneham Courtenay affects everyone who depends on it.

Common problems we fix in Nuneham Courtenay
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Nuneham Courtenay, that is air they breathe for hours at a time.
Keep an eye out for these warning signs:
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
Hospitals such as Littlemore Hospital (about 2.3 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Nuneham Courtenay are no different.
What your quote should include
- Exactly which parts of the system are covered
- What hours they’ll be on site
- How VAT is shown on the quote
- Whether the quote is based on a survey or pictures
Looking after it afterwards
Results last longer with the right care. We suggest:
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Change filters on schedule and log each change
- Watch for drips or damp patches near the plant
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What affects the quote in Nuneham Courtenay
You’ll get a fixed price before any work starts. It’s based on:
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
- The condition we find in the survey
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
When you call or email, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Seeing the system in photos first means the trip to Nuneham Courtenay can be planned properly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need

Part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Common questions in Nuneham Courtenay
Do you cover Nuneham Courtenay for AHU cleaning?
Yes. We work across London and the South East, and Nuneham Courtenay is part of that. A fixed quote usually follows within one working day of the survey details.
Do you cover smaller places like Nuneham Courtenay?
Yes. Villages and rural sites across the South East are part of our work, Nuneham Courtenay included. The journey is planned ahead, so a few details about the route help.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
