AHU cleaning in Woodstock, done properly
Our AHU cleaning covers sites in Woodstock and the rest of Oxfordshire, 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, dampers and louvres and drain trays, and people most often call us about debris and leaves in the fresh air intake and air handling units never cleaned inside.
Visits to a place like Woodstock are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Do you need AHU cleaning in Woodstock?
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
- Air handling units never cleaned inside
Ventilation work in and around Woodstock is risk-based: inspect, then clean what needs it.
What to look for in a quote
- How areas they can’t reach will be recorded
- Whether VAT is included
- Proof of insurance
- Whether the figure could change on the day
What affects the quote in Woodstock
We quote each job individually. This is what makes a difference:
- The times the site is available
- Whether several sites go on one quote
- How easy every part is to reach
- The condition of the system
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
Getting a quote doesn’t take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Aftercare tips
So the system stays in good health:
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
- Report musty smells from the vents right away
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, rather than waiting for a problem.
Ventilation in Woodstock buildings
Going by the FSA’s register, there are about 3 caring premises (care homes, nurseries and hospitals) and about 7 hotels, B&Bs and guest houses serving food within roughly a mile and a half of the centre of Woodstock. Busy, occupied buildings like these are where clean supply air matters most. At about 59 miles from central London, Woodstock sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
If you manage a school such as Woodstock Church of England Primary School, ventilation cleaning is best booked for the holidays.

What AHU cleaning cannot fix
Before you book, it helps to know what’s not included:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
Where we work
- Dampers and louvres
- Internal panels
- Filter sections
- Drain trays
- Supply and extract fans
- Heating and cooling coils
Why it’s worth doing now in Woodstock
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A site near Woodstock that has to close at short notice is hard to cover for.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Questions from Woodstock
Do you cover smaller places like Woodstock?
Yes, we work in villages as well as towns, and Woodstock is covered. The journey is planned ahead, so a few details about the route help.
Do you cover Woodstock for AHU cleaning?
Yes, Woodstock is covered. Just ring 0345 646 2711 or email us with a few details of the site.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare in Woodstock and across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. A site near Woodstock typically has room to park, so the questions are about access to the system and your hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
