AHU cleaning in Felpham, done properly
Our AHU cleaning covers sites in Felpham and the rest of West Sussex, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with intake sections clogged with outdoor debris and coils clogged with dust and debris, across dampers and louvres, drain trays and internal panels.
In a place like Felpham, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Common problems we fix in Felpham
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
It’s time to book a visit if you see:
- Condensate trays that will not empty
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Dust built up on fan impellers
Healthcare ventilation, from large hospitals like Bognor Regis War Memorial Hospital (about 1 mile west) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- Whether the price is fixed
- Which accreditations they hold, and whether you can check them
- Whether the work can be done while the site is closed
- How areas they can’t reach will be recorded
How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Tell us when your site near Felpham is quiet and the visit will be booked for then.
- 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.
- 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
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Have your last certificate or report to hand
Ask for a quote
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.
Advice
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Common questions in Felpham
Can you clean school ventilation in Felpham during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 20 schools and colleges with food registrations within roughly a mile and a half of Felpham. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you come out to Felpham?
Yes, Felpham 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 give a certificate after the clean?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. We will ask for anything else we need.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
How long does an AHU clean take?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Between visits
Results last longer with the right care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Felpham buildings and their air
Going by the FSA’s register, there are about 20 schools, colleges and universities, about 19 hospitals, care homes and childcare premises and about 7 hotels, B&Bs and guest houses serving food within 1.5 miles or so of the middle of Felpham. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Felpham, about 55 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. For Felpham, the closest hospital is Bognor Regis War Memorial Hospital, roughly 1 mile west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Felpham Community College, ventilation cleaning is best booked for the holidays.
