Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
About our AHU cleaning in Selsey
Where a building in Selsey has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include air handling units due a clean after building work and stale or musty smells from the ventilation, on supply and extract fans, heating and cooling coils and dampers and louvres.
Many schools and offices in a town like Selsey have a mix of older and newer ventilation. The work starts with an inspection to decide what needs cleaning.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
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.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Send us pictures of the system and we can plan most of a visit in Selsey before we arrive.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system

Questions from Selsey
Do you clean school ventilation in Selsey in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Selsey. Just ring 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you work at weekends in Selsey?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
Is Selsey in your area?
Yes. We cover Selsey and across West Sussex, as part of our work across South East England and London. To book, phone us on 0345 646 2711 or use the quote form.
What about areas you can’t get to?
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.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
How long does an AHU clean take?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.

What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.
What the work covers
- Drain trays
- Filter sections
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Internal panels
Between visits
Results last longer with the right care. Here’s what we suggest:
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
AHU cleaning in Selsey: local notes
There are about 12 hospitals, care homes and childcare premises on the FSA’s food hygiene register within roughly a mile and a half of the centre of Selsey. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting.
An inspection comes first for any ventilation job around Selsey, so the cleaning matches what’s there. Wherever a school like Seal Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a town like Selsey, a problem caught early is a planned visit, not an emergency.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
