AHU cleaning in Horsted Keynes
We clean air handling units for buildings in Horsted Keynes and across West Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with dirty filters cutting the airflow and odours coming through the supply air, we can put it right.
Somewhere as small as Horsted Keynes, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Managing agents and facilities teams in Horsted Keynes
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
What happens on the day
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Horsted Keynes, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Let us know about permits to work or site inductions
Getting a quote
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Advice
What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Faulty motors, drives or bearings
- Damaged coils beyond cleaning
- A system that is undersized for the building
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Horsted Keynes
- Filter sections
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Heating and cooling coils
What happens if it’s left?
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. Our emergency line runs 24/7, but a planned visit to Horsted Keynes is calmer for everyone.
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 the price is fixed before work begins.

What the work involves, part by part
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.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

What else we do in Horsted Keynes
Horsted Keynes: your questions answered
Is Horsted Keynes in your area for AHU cleaning?
Yes, we work in Horsted Keynes and the places around it. Just give us a ring on 0345 646 2711, or send details by email with a few details of the site.
Do you work at weekends in Horsted Keynes?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Horsted Keynes needn’t be disturbed. Your opening times are the first thing we ask for.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
What we’re called out for in Horsted Keynes
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Clients normally contact us when they notice one of these:
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
Wherever a school like St Giles CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- Whether they’re fully insured
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
