Westergate AHU cleaning
AHU cleaning in Westergate from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.

- Dust-coated heating and cooling coils
Signs you need AHU cleaning in Westergate
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
It’s time to book a visit if you see:
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
School buildings such as Aldingbourne Primary School are normally done in the holidays, so classrooms are not disturbed.
Before you book anyone
- What paperwork you get at the end
- Whether the price is fixed
- Whether the whole system is included, or only the parts that are easy to reach
- How areas they can’t reach will be recorded
AHU cleaning in Westergate
We clean air handling units for buildings in Westergate and across West Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers drain trays, filter sections and internal panels, and the jobs we see most are coils clogged with dust and debris and units needing a clean before a new tenant or handover.
In a smaller place like Westergate, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the quote in Westergate
The diagnosis comes before the price. We look at:
- Any permits to work or inductions
- The size of the system
- Whether several sites go on one quote
- What state the system is in
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
There’s no need for technical detail. Just send:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Problems your staff have spotted
- The times we could work without disrupting the site
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Tell us about any gates, ladders or locked plant areas at your site near Westergate when you book.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site

Advice
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Booking ahead lets us plan the trip to Westergate at a time that suits you.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

What AHU cleaning looks like in Westergate
Food Standards Agency records list about 7 schools, colleges and universities and about 9 hospitals, care homes and childcare premises registered as food businesses within roughly a mile and a half of the centre of Westergate. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Westergate’s nearest hospital, Bognor Regis War Memorial Hospital, is about 3.1 miles south. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Westergate, about 52 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
If you run a surgery, dental practice or care home near Westergate, clean ventilation matters as much to you as to a hospital like Bognor Regis War Memorial Hospital (about 3.1 miles south).

FAQs for Westergate
Do you clean school ventilation in Westergate in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Westergate. Just call us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Is Westergate within the area you cover?
Yes, we work in villages as well as towns, and Westergate is covered. The journey is planned ahead, so a few details about the route help.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply ring 0345 646 2711 or email us.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How much does AHU cleaning cost in Westergate?
It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711 or drop us a line with the site type, opening hours and a few pictures.
What a clean won’t put right
Before booking, it helps to know what’s not included:
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.

- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Internal panels
How the job changes from site to site
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.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
