About our AHU cleaning in Five Oaks
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers dampers and louvres, internal panels and heating and cooling coils, and common reasons people get in touch are dust-coated heating and cooling coils and filters that are clogged or overdue.
Somewhere as small as Five Oaks, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Five Oaks: your questions answered
Do you cover smaller places like Five Oaks?
Yes, we work in villages as well as towns, and Five Oaks is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you do school ventilation cleaning in Five Oaks in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Five Oaks. Tell us your holiday dates and we will book the visit for when the site is empty.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
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 call 0345 646 2711 or send us an email.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
- Note any water around the unit or leaks below it
- Don’t ignore odours coming through the grilles
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
What we are called out for in Five Oaks
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Most sites get in touch when they notice something like this:
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
- Odours coming through the supply air
- Dirty fans and fan housings
School buildings such as The Weald School are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- What paperwork you get at the end
- What insurance they carry
- Whether the quote shows VAT
- How areas they cannot reach will be recorded

Managing agents and facilities teams in Five Oaks
Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Work can be phased by floor, building or site around the people who use them.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
What happens on the day
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Five Oaks, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
