What we are called out for in Lower Arncott
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Signs it’s time to call us include:
- Condensate trays that will not empty
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
If you run a surgery, dental practice or care home near Lower Arncott, clean ventilation matters as much to you as to a hospital like Bicester Community Hospital (about 3.2 miles north-west).
Questions to ask before you book
- Whether the quote shows VAT
- What happens if part of the system can’t be accessed
- Proof of insurance
- What’s included in the scope, part by part
How we handle AHU cleaning in Lower Arncott
An air handling unit is the heart of a building’s ventilation: 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, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include coils clogged with dust and debris and fan sections that haven’t been cleaned in years, on filter sections, supply and extract fans and internal panels.
In a village or hamlet like Lower Arncott, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Leave it or put it right?
Standing water in a drain tray does not clear itself. 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. It’s worth booking a check, because nobody sees inside a duct day to day.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Why book with us
- Each visit written up, with pictures

What else we do in Lower Arncott
Lower Arncott questions
Do you clean school ventilation in Lower Arncott in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Lower Arncott. Just call 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you cover smaller places like Lower Arncott?
Yes, we work in villages as well as towns, and Lower Arncott is covered. Just mention lanes, gates or anything else about the site when you book.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Multi-site and managed buildings
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.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
AHU cleaning around Lower Arncott
Bicester Community Hospital is the nearest hospital, about 3.2 miles north-west of Lower Arncott. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. About 50 miles out from central London, Lower Arncott is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Five Acres Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
If you are not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer before you book.
What the work covers
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
- Supply and extract fans
What affects the quote in Lower Arncott
We quote each job individually. This is what makes a difference:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- Site rules, permits and inductions
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. In a small place like Lower Arncott, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about parking and loading
