Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How we handle AHU cleaning in The Haven
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you have dust built up on fan impellers and plant that has been serviced but not cleaned, we can help, from internal panels, drain trays and heating and cooling coils onwards.
Somewhere as small as The Haven, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near The Haven, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

Signs you need AHU cleaning in The Haven
Whatever surrounds a building in The Haven, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
The symptoms we’re asked about most include:
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
Healthcare buildings such as Horsham Hospital, about 5.3 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near The Haven, yours matters too.
What your quote should include
- Proof of insurance
- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
- Whether a written report and pictures are included
Honest limits
It’s worth knowing the limits before booking:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think before you book.
Where we work
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Do not store bins or materials near the intake
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
