AHU cleaning in Cressing: local notes
The FSA’s food hygiene register lists about 3 care, childcare and hospital premises with registered kitchens or food service across Cressing and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Cressing, about 39 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Cressing’s nearest hospital, William Julien Courtauld Hospital, is about 2.7 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Hospitals such as William Julien Courtauld Hospital (about 2.7 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Cressing are no different.

About our AHU cleaning in Cressing
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers filter sections, internal panels and dampers and louvres, and the jobs we see most are filters that are clogged or overdue and condensate trays that won’t empty.
Work in a small place like Cressing starts with agreeing access and timings.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- A single visit or a regular plan
- How easy every part is to reach
- The scale of the work
- The number of sites or systems
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- A few general shots of the system
- The postcode and the type of business
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
Questions from Cressing
Do you do school ventilation cleaning in Cressing in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Cressing. Just phone us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Can you get to a site in Cressing?
Yes. Villages and rural sites across the South East are part of our work, Cressing included. Just mention lanes, gates or anything else about the site when you book.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. At the end, the area is cleaned down.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Why it’s worth doing now in Cressing
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. Out of sight is the usual reason a rural system goes too long without attention.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- Full insurance on every job
- Photo reports with every job
- Ventilation hygiene specialists since 2009
- Fixed quotes from a survey or photos

Common problems we fix in Cressing
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Most sites get in touch after spotting something like this:
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
School buildings such as Cressing Primary School are typically done in the holidays, so classrooms are not disturbed.
What your quote should include

- What insurance they carry
- How VAT is shown on the quote
- How areas they can’t reach will be recorded

Honest limits
In fairness, there are a few things this work will not fix:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean

What we work on in Cressing
- Dampers and louvres
- Drain trays
- Supply and extract fans
- Filter sections
- Internal panels
- Heating and cooling coils
Keeping the system healthy
Results last longer with the right care. We suggest:
- File each AHU report in the maintenance log
- Stick to the filter change plan
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
What we do, step by step
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. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Cressing run smoothly.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
