Islip AHU cleaning
Need AHU cleaning in Islip? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Condensate trays that will not empty
Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Systems in rural buildings are often out of sight and out of mind.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What you get with us
- Ventilation hygiene specialists since 2009
- Every job surveyed first

How we handle AHU cleaning in Islip
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Typical jobs include filters that are clogged or overdue and blocked condensate drains and slimy trays, across drain trays, dampers and louvres and heating and cooling coils.
Somewhere as small as Islip, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How we price AHU cleaning
A fixed price needs a few facts first. We check:
- Where the site is and how we reach it
- How easy every part is to reach
- The number of sites or systems
- One-off work versus a regular cycle
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or email us, and we will explain what it covers.
What to send for a quote
When you contact us, these details help:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Your last certificate, test record or report
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 many jobs can be priced from that alone.
When something else is needed
AHU cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.
What we work on in Islip
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Internal panels
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Do not store bins or materials near the intake
- Keep inspection doors on the unit in good order
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Ventilation in Islip buildings
We cover Islip, about 54 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Churchill Hospital is the nearest hospital, about 4.1 miles south of Islip. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare buildings such as Churchill Hospital, about 4.1 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Islip, yours matters too. Classrooms and halls at schools such as Dr South's Church of England Primary School are easiest to work in when pupils are away. If you run an office near Islip station, its supply ductwork can gather dust for years before anyone looks inside.
Islip is about 5 miles north of Oxford, in Oxfordshire. We carry out AHU cleaning for businesses, landlords and public buildings in Islip and the rest of Oxfordshire. Across Oxfordshire, we cover 443 places, Islip among them.
We cover every part of OX5 for AHU cleaning and the streets around it. That includes premises on High Street, King's Head Lane and Middle Way and nearby roads. If your site is just outside Islip, we cover Gosford (2 miles south-west), Hampton Poyle (2 miles north-west), Kidlington (2 miles west), Bletchingdon (3 miles north-west) and Weston-on-the-Green (3 miles north). Within a short drive, we also cover Oxford (5 miles south), Didcot (15 miles south), Bicester (6 miles north-east), Abingdon-on-Thames (10 miles south), Witney (11 miles west) and Thame (12 miles south-east).
Landmarks near Islip
Typical jobs here are in premises near The Red Lion Inn and Gosford Hill School. There’s a railway station in Islip itself: Islip station. Nearby you will also find Churchill Hospital (4.1 miles south). Not far away are Otmoor RSPB reserve and Headington Hill.
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Islip and turn up when the site is quiet.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids

Questions from Islip
Can the work in Islip be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Islip doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
Can you get to a site in Islip?
Yes. Islip is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you have insurance?
Yes. We are fully insured, and the details are available on request.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
