AHU Cleaning in Pyrton
AHU cleaning across Pyrton and nearby, timed so the site keeps working and finished with a written report and pictures.
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Air handling units due a clean after building work
Aftercare tips
So the system stays in good health:
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
- Plan the next inspection before the last report gets filed away
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
AHU cleaning in Pyrton
We clean air handling units for buildings in Pyrton and across Oxfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers internal panels, filter sections and dampers and louvres, and the jobs we see most are dirty coils holding back the airflow and air handling units never cleaned inside.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What happens on the day
Every visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. If you can send pictures, we can arrive in Pyrton knowing what to expect.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Arrange a key holder or contact on site
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
How to get 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.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Leave it or put it right?
If people in a building in Pyrton complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. If the system at a site near Pyrton fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.

Common questions in Pyrton
Do you work in villages like Pyrton?
Yes, we work in villages as well as towns, and Pyrton is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can ventilation in schools around Pyrton be cleaned out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Pyrton. Send us your term dates when you call 0345 646 2711, or email photos, and we will fit the work in.
Is a quote from photos possible?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Do you work evenings or weekends?
Yes, wherever it helps the building. We plan the shutdown window with you.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

What we are called out for in Pyrton
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Common reasons sites call us include:
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Odours coming through the supply air
For schools like Watlington Primary School, the holidays are the usual time to inspect and clean ventilation.

What AHU cleaning cannot fix
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
