Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why book with us
- Evenings, overnight and weekends, plus 24/7 emergency callout
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- We diagnose before we treat
- Fully insured
AHU cleaning in West Dean, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. If you have dust-coated heating and cooling coils and stale or musty smells from the ventilation, we can help, from dampers and louvres, heating and cooling coils and supply and extract fans onwards.
Somewhere as small as West Dean, 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.
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.

What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to West Dean.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

What the work involves, part by part
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. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
West Dean: your questions answered
Can you get to a site in West Dean?
Yes, West Dean is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you clean school ventilation in West Dean in the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of West Dean. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.
How much does AHU cleaning cost in West Dean?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
How long does an AHU clean take?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, including evenings or weekends.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What else we do in West Dean
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Look at the condensate drain whenever the unit is serviced
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
What affects the cost of AHU cleaning
You’ll get a fixed price before work begins. It’s based on:
- The condition of the system
- Access, including roofs, risers and ceiling voids
- How big the system is
- Whether several sites go on one quote
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we will price it together.
Asking for a quote
We can often survey from pictures. The most useful are:
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or use the quote form.
