How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Travel, parking and unloading
- The condition we find in the survey
- The scale of the work
- The times the site is available
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
To get a fixed quote, call us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
How we handle AHU cleaning in Norton
We clean air handling units for buildings in Norton and across West Sussex, working to TR19® Air, 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. Common call-outs are for filters that are clogged or overdue and dust built up on fan impellers, on heating and cooling coils, filter sections and drain trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Norton
The FSA’s food hygiene register lists about 4 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within roughly a mile and a half of the centre of Norton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Norton’s nearest hospital, St Richard's Hospital, is about 3.9 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. We cover Norton, about 52 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.
Healthcare buildings such as St Richard's Hospital, about 3.9 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Norton, yours matters too.

Around Norton
Around Norton, our work takes us to kitchens and buildings near The Winterton Arms Public House and Eastergate CofE Primary School.

What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Norton.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call 0345 646 2711 or drop us a line.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What we’re called out for in Norton
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
The symptoms we are asked about most include:
- Air handling units due a clean after building work
- Drain trays holding standing water
- Filters that are clogged or overdue
- Dust built up on fan impellers
Wherever a school like Ormiston Six Villages Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Common questions in Norton
Can you come to Norton after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Norton does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.
Do you clean school ventilation in Norton in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Norton. Just call us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Is Norton in your area?
Yes. Our technicians work in Norton, within the South East and London area we cover.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What a clean will not put right
It’s worth knowing the limits before booking:
- Faulty motors, drives or bearings
- Building management system faults
- Airflow problems caused by the system’s design
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think.
What we work on in Norton
- Filter sections
- Drain trays
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Dampers and louvres
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Planning a trip to Norton ahead is easier for everyone than a rushed one.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Between visits
So the system stays in good health:
- Look at the condensate drain whenever the unit is serviced
- Diary the inspection date recommended in the report
- Report stiff or damaged access doors
- Report musty smells from the vents right away
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
