AHU cleaning for kitchens and businesses in Chadlington
If the units serving a building in Chadlington have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you are dealing with dust built up on fan impellers and plant that needs cleaning after a refit, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Chadlington questions
Do you work in villages like Chadlington?
Yes. Chadlington is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Chadlington after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Chadlington needn’t be disturbed. Your opening times are the first thing we ask for.
Can you quote from photos?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If pictures are not enough, we will survey first.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How long does an AHU clean take?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, out of hours if needed.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How the job changes from site to site
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so you can decide on any repairs.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building around the people who use them.
What happens on the day
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Chadlington before we set off.
- 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.
Getting ready for the visit
- Agree a time when the area can be out of use
- Let us know about parking and loading
- Clear loose items from the work area

Why act early in Chadlington
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Equipment tucked in a roof space or outbuilding near Chadlington rarely gets looked at unless someone books it.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711, or send details by email for straight advice and a fixed quote.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
What affects the quote in Chadlington
The diagnosis comes before the price. The main factors are:
- Parking and loading at the site
- One-off work versus a regular cycle
- How easy every part is to reach
- Site rules, permits and inductions
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
What we need to know
When you contact us, it’s useful to have:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, call us on 0345 646 2711, or send details by email.
