About our AHU cleaning in Headington
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you are dealing with dust-coated heating and cooling coils and leaves and litter drawn into the unit, we can put it right.
In a place like Headington, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Headington simpler. Around Headington, a kitchen or building out of action is missed right away.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.

What else we do in Headington
Do you need AHU cleaning in Headington?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
What we’re most often called out for:
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Dirty filters cutting the airflow
If you manage a school such as St Andrew's Church of England Primary School, ventilation cleaning is best booked for the holidays.

Ventilation in Headington buildings
There are about 23 schools, colleges and universities, about 23 care, childcare and hospital premises and about 7 hotels, B&Bs and guest houses on the FSA’s food hygiene register within 1.5 miles or so of the middle of Headington. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Headington, about 51 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. Headington’s nearest hospital, Churchill Hospital, is about under half a mile west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare ventilation, from large hospitals like Churchill Hospital (about within half a mile west) to small clinics, depends on clean filters, coils and ducts.

- Filter sections
- Drain trays
- Heating and cooling coils
- Supply and extract fans
Between visits
Good habits slow the build-up between visits. Our tips:
- Don’t store bins or materials near the intake
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Headington and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Tell us when your site near Headington is quiet and the visit will be booked for then.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Clear the space around the work
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
