Different parts, different methods
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
About our AHU cleaning in Northmoor
Our AHU cleaning covers sites in Northmoor and the rest of Oxfordshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. We’re often asked to deal with dust built up on fan impellers and drain trays holding standing water, across internal panels, heating and cooling coils and dampers and louvres.
Somewhere as small as Northmoor, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, and we’re 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.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Clear leaves and litter away from the intake
- Report water on the plant room floor
- Stick to the filter change plan
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Ventilation in Northmoor buildings
At about 58 miles from central London, Northmoor sits well inside the area we cover. Evening, overnight and weekend visits are all possible. About 5.4 miles south-east of Northmoor is Abingdon Community Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Ventilation work in and around Northmoor is risk-based: inspect, then clean what needs it. Healthcare ventilation, from large hospitals like Abingdon Community Hospital (about 5.4 miles south-east) to small clinics, depends on clean filters, coils and ducts.
Northmoor is about 6 miles north-west of Abingdon-on-Thames, in Oxfordshire. Anywhere in OX29, we can take on AHU cleaning. Northmoor is one of 443 towns, villages and districts in Oxfordshire we cover for AHU cleaning. There’s also a page for Oxford, roughly 7 miles from Northmoor.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
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.

What affects the quote in Northmoor
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Where the site is and how we reach it
- Any permits to work or inductions
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
When you contact us, it’s useful to have:
- The postcode and the type of business
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Wide pictures of the system and the area around it
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or drop us a line.
Why it’s worth doing now in Northmoor
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. With notice, the visit to Northmoor can be fitted around your bookings and events.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.

What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Building management system faults
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Parts of the system we cover
- Drain trays

The process
We are 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. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Northmoor are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
