AHU cleaning in Radwinter, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers filter sections, heating and cooling coils and dampers and louvres, and common reasons people get in touch are odours coming through the supply air and air handling units never cleaned inside.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

For landlords and multi-site operators
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We also work for facilities teams across offices, schools and healthcare in Radwinter and across Essex. Larger estates can be phased building by building to keep disruption down.
Leave it or put it right?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s simpler to plan the work at Radwinter now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
Why Radwinter businesses choose us
- One number for every site across the South East and London
- A fixed price before any work starts
- Full insurance on every job
- Out-of-hours work and a 24/7 emergency line

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
When to call us in Radwinter
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Units that have only ever had filter changes
- Condensate trays that will not empty
- Odours coming through the supply air
- Dirty filters cutting the airflow
Saffron Walden Community Hospital, about 3.6 miles west, is the nearest hospital to Radwinter, and healthcare sites of every size need their supply air kept clean.

What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Radwinter, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or send details by email.
Advice
Looking after it afterwards
Once we have finished, these simple steps help:
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
