Air handling unit cleaning in Black Bourton, Oxfordshire
Need AHU cleaning in Black Bourton? We survey first, give you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Black Bourton, the journey is planned ahead and the visit arranged around the site’s hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms

About our AHU cleaning in Black Bourton
If the units serving a building in Black Bourton have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for plant that needs cleaning after a refit and drain trays holding standing water, on dampers and louvres, supply and extract fans and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Flag stale or damp smells in the supply air
- Stick to the filter change plan
- Report stiff or damaged access doors
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
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. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
- Building management system faults
If in doubt, call us on 0345 646 2711 or email us and we will say what we think before booking.
What the work covers
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
Signs you need AHU cleaning in Black Bourton
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
Hospitals such as Longworth Hospital (about 5.4 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Black Bourton are no different.
Before booking anyone
- Whether the work can be done while the site is closed
- What insurance they carry
- Whether the whole system is included, or only the parts that are easy to reach
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What the work involves, part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.

Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
What AHU cleaning looks like in Black Bourton
Longworth Hospital is the nearest hospital, about 5.4 miles south of Black Bourton. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like St Peter's Church of England School has ducted ventilation, a half-term visit keeps the work out of lesson time.
