AHU cleaning in Houghton, done properly
Our AHU cleaning covers sites in Houghton and the rest of West Sussex, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you’re dealing with fan sections that haven’t been cleaned in years and filters that are clogged or overdue, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, 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.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. If you can send pictures, we can arrive in Houghton knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Houghton: your questions answered
Do you do school ventilation cleaning in Houghton in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Houghton. Send us your term dates when you ring 0345 646 2711 or send us an email, and we’ll fit the work in.
Can you work in Houghton outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Houghton can fit around your hours. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call us on 0345 646 2711 or send us an email.
How long does an AHU clean take?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you cover Houghton?
Yes. Houghton is part of the area we cover, within the South East and London area we cover.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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 is our job.
Fixed quotes for AHU cleaning in Houghton
The quote reflects the site in front of us. We take into account:
- The scale of the work
- One-off work versus a regular cycle
- Site rules, permits and inductions
- Travel, parking and unloading
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What to send for a quote
When you contact us, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- The postcode and the type of business
- Any previous report or certificate
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

There are about 3 schools, colleges and universities on the FSA’s food hygiene register in Houghton and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. We cover Houghton, about 46 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. The nearest hospital to Houghton is Arundel and District Hospital, about 2.7 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

When to call us in Houghton
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Signs it’s time to call us include:
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
- Odours coming through the supply air
- Intake sections clogged with outdoor debris
If you manage shops or offices close to Amberley station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- If the quote is a fixed price or an estimate
- Whether the work can be done while the site is closed
- What insurance they carry
What AHU cleaning can’t fix
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
