AHU cleaning in Dean Court, done properly
Where a building in Dean Court has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Typical jobs include intake sections clogged with outdoor debris and dirty fans and fan housings, on dampers and louvres, filter sections and internal panels.
In a smaller place like Dean Court, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Why deal with it now?
If people in a building in Dean Court complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A site near Dean Court that has to close at short notice is hard to cover for.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

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 send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
What affects the cost of AHU cleaning
We do not publish a price list, because no two systems are the same. The quote depends on:
- The size of the system
- Where the site is and how we reach it
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or drop us a line.
Common problems we fix in Dean Court
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Dirty coils holding back the airflow
- Drain trays holding standing water
Hospitals such as Radcliffe Infirmary (about 2.2 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Dean Court are no different.

Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before booking.

Dean Court buildings and their air
Radcliffe Infirmary is the nearest hospital, about 2.2 miles east of Dean Court. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 55 miles out from central London, Dean Court is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Matthew Arnold School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Dean Court: your questions answered
Can you come to Dean Court after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Dean Court doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Dean Court within the area you cover?
Yes, we work in villages as well as towns, and Dean Court is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where necessary.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Managing agents and facilities teams in Dean Court
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Facilities teams in offices, schools and healthcare sites book us too in Dean Court and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Tell us when your site near Dean Court is quiet and the visit will be booked for then.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
