AHU cleaning in High Salvington
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers filter sections, heating and cooling coils and internal panels, and people most often call us about intake sections clogged with outdoor debris and blocked condensate drains and slimy trays.
In a place like High Salvington, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
High Salvington: your questions answered
Can ventilation in schools around High Salvington be cleaned out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of High Salvington. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Can the work in High Salvington be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
How long will the unit be out of action?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, out of hours if needed.

How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. A site near High Salvington usually has room to park, so the questions are about access to the system and your hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need

Common problems we fix in High Salvington
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
These are the problems we see most often:
- Dust built up on fan impellers
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Filters that are clogged or overdue
Healthcare ventilation, from large hospitals like Worthing Hospital (about 2.9 miles south-east) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- Whether the work can be done while the site is closed
- If the quote is a fixed price or an estimate
- Whether VAT is included
- How they set the interval to the next visit
What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- The scale of the work
- Whether we need access equipment or extra panels
- Travel, parking and unloading
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What we need to know
To speed up the quote, send us:
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- A few general shots of the system
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Why act early in High Salvington
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. Even a site near High Salvington that is only busy part of the week needs its system checked on a schedule.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

We also work for facilities teams across offices, schools and healthcare across West Sussex. Work can be phased by floor, building or site to keep disruption down.
