West Sussex · Air handling unit cleaning
Air handling unit cleaning in Street End, West Sussex
Professional AHU cleaning in and around Street End, booked around your opening hours and finished with a written report and pictures.
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Report water on the plant room floor
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Report musty smells from the vents right away
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
AHU cleaning in Street End
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. If you have drain trays holding standing water and leaves and litter drawn into the unit, we can help, from heating and cooling coils, internal panels and drain trays onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What we’re called out for in Street End
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Look out for these warning signs:
- Units needing a clean before a new tenant or handover
- Condensate trays that won’t empty
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
For schools like Sidlesham Primary School, the holidays are the usual time to inspect and clean ventilation.
Before you book anyone
- What insurance they carry
- When the next visit should be, and why
- What happens if part of the system can’t be accessed
- Proof of accreditation you can verify
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Street End are booked in advance, at a time that suits whoever runs the site.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet

Advice
What affects the quote in Street End
Your quote is based on your site. We consider:
- The number of sites or systems
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- How big the system is
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or drop us a line, and we’ll talk you through it.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Your last certificate, test record or report
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711 or use the quote form.
Questions from Street End
Do you cover smaller places like Street End?

How much does AHU cleaning cost in Street End?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
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.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

When it’s something else
To be straight with you, some problems need a different fix:
- Faulty motors, drives or bearings

What we work on in Street End
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Filter sections

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. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
