AHU cleaning in Chiltington, done properly
Our AHU cleans for sites in Chiltington cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have drain trays holding standing water and units needing a clean before a new tenant or handover, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Facilities teams in offices, schools and healthcare sites book us too across East Sussex. Larger estates can be phased building by building around the people who use them.

How the visit works

All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Chiltington, the date and timings are agreed with you well before the day.

- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.

Advice
What we are called out for in Chiltington
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Look out for any of the following:
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
For schools like Chailey School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- What hours they’ll be on site
- Whether a survey comes first
- Whether VAT is included
- Whether the price is fixed
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
- Change filters on schedule and log each change
We recommend when the unit should next be inspected or cleaned, 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.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
When something else is needed
Before you book, it helps to know what’s not included:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can ring 0345 646 2711 or send us an email and we’ll tell you honestly.

What else we do in Chiltington
What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
What affects the quote in Chiltington
The price is fixed before any work begins. It takes into account:
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
We can often survey from photos. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
