About our AHU cleaning in Poundon
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. The work covers internal panels, supply and extract fans and drain trays, and people most often call us about units that have only ever had filter changes and fan sections that haven’t been cleaned in years.
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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Stick to the filter change plan
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Questions from Poundon
Can you work in Poundon outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you work in villages like Poundon?
Yes, Poundon is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Are you fully insured?
Yes. We are fully insured, and the details are available on request.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Common problems we fix in Poundon
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Signs it’s time to call us include:
- Odours coming through the supply air
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
If you run a surgery, dental practice or care home near Poundon, clean ventilation matters as much to you as to a hospital like Bicester Community Hospital (about 4.6 miles south-west).
What to look for in a quote
- How areas they can’t reach will be recorded
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- If they look at the system before pricing
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Systems in rural buildings are often out of sight and out of mind.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Poundon are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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 about permits to work or site inductions
- Find the previous report, if there is one
- Move anything stored near the system
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or drop us a line.

When it’s something else
In fairness, some problems need a different fix:
- Controls and BMS settings that run the unit
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
