What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- How many systems or sites are involved
- Site rules, permits and inductions
- How easy every part is to reach
- Parking and loading at the site
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

AHU cleaning in Ferring
We clean air handling units for buildings in Ferring and across West Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include stale or musty smells from the ventilation and filters that are clogged or overdue, across dampers and louvres, heating and cooling coils and internal panels.
Visits to a place like Ferring are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site 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. Evenings, weekends or a closed day all work for a site in a place like Ferring.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions

FAQs for Ferring
Can you get to a site in Ferring?
Yes, we work in villages as well as towns, and Ferring is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Ferring outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How long does it take to clean an air handling unit?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can ring 0345 646 2711 or send us an email to plan it.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
What a clean won’t put right
In fairness, there are a few things this work will not fix:
- A system that’s undersized for the building
- Leaking heating or cooling coils
- Building management system faults
If you are not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer.
Where we work
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Internal panels

- Supply and extract fans
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

Aftercare tips
After the visit, a few habits help the work last:
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
AHU cleaning around Ferring
Food Standards Agency records list about 15 schools, colleges and universities and about 12 caring premises (care homes, nurseries and hospitals) registered as food businesses across Ferring and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Zachary Merton Hospital is the nearest hospital, about 2.3 miles west of Ferring. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Ferring, about 50 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
If you manage offices or shops near Goring-By-Sea station, their ventilation can be inspected and cleaned out of hours. Hospitals such as Zachary Merton Hospital (about 2.3 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Ferring are no different. For schools like Ferring CofE Primary School, the holidays are the usual time to inspect and clean ventilation.

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. 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. A planned visit to Ferring fits your hours; an emergency does not.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.
