About our AHU cleaning in Brighton and Hove
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers supply and extract fans, filter sections and dampers and louvres, and common reasons people get in touch are filters that are clogged or overdue and dirty coils holding back the airflow.
Around a town like Brighton and Hove, the buildings with ducted ventilation are typically offices, schools, surgeries and care homes. Their supply and extract ducts all gather dust over time.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Different parts, different methods
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- How many systems or sites are involved
- The condition of the system
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before work begins.
What we need to know
When you contact us, it’s useful to have:
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
- A few general shots of the system
For a fixed quote, give us a ring on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
When something else is needed
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
- Dirty ducts beyond the unit itself
If you’re not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Common questions in Brighton and Hove
Can the work in Brighton and Hove be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Brighton and Hove doesn’t have to lose a day’s trading. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you clean school ventilation in Brighton and Hove in the holidays?
Yes, holiday work suits schools best. With about 38 schools and colleges on the FSA’s register within roughly a mile and a half of Brighton and Hove, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
Is a quote from photos possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures are not enough, we will survey first.
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.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What should I send you?
A short description and a few photos plus the address and your hours. If we need more, we’ll ask.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
When to call us in Brighton and Hove
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
The symptoms we are asked about most are:
- Dirty fans and fan housings
- Odours coming through the supply air
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Montefiore Hospital (about 1.5 miles east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
- What paperwork you get at the end

Why it’s worth doing now in Brighton and Hove
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A small fault found now is a quick job; the same fault found later can close the site.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
