How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- Parking and loading at the site
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 play a part.
Asking for a quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
AHU cleaning for kitchens and businesses in Dormans Park
We clean air handling units for buildings in Dormans Park 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. We’re often asked to deal with coils clogged with dust and debris and air handling units never cleaned inside, across drain trays, filter sections and heating and cooling coils.
In a village or hamlet like Dormans Park, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
When something else is needed
Not every problem is solved by AHU cleaning, and we will tell you before any work starts. It doesn’t solve:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Damaged coils beyond cleaning
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.
Where we work
- Drain trays
- Filter sections
- Dampers and louvres
- Supply and extract fans

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Dormans Park, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system

Dormans Park: your questions answered
Can you come to Dormans Park after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Dormans Park keeps running as normal. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Do you clean school ventilation in Dormans Park in the holidays?
Yes. The holidays are the usual time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Dormans Park, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Can you quote from photos?
Typically, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What we’re called out for in Dormans Park
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Dormans Park, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Plant that has been serviced but not cleaned
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
Wherever a school like Bush Davies School of Theatre Arts has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Whether the quote is based on a survey or pictures
- Whether they recommend a next date
- What’s included in the scope, part by part
- When they can work, and whether that’s outside your opening hours
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
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.
Why it’s worth doing now in Dormans Park
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. In a place like Dormans Park, ductwork and fans are easy to forget until something goes wrong.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
