AHU cleaning in Lyminster, done properly
Our AHU cleans for sites in Lyminster cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have dust-coated heating and cooling coils and stale or musty smells from the ventilation, we can help, from heating and cooling coils, internal panels and supply and extract fans onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What AHU cleaning looks like in Lyminster
There are about 10 schools, colleges and universities, about 21 caring premises (care homes, nurseries and hospitals) and about 12 hotels and B&Bs on the FSA’s food hygiene register within roughly a mile and a half of the centre of Lyminster. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.9 miles north-west of Lyminster is Arundel and District Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. We cover Lyminster, about 50 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare ventilation, from large hospitals like Arundel and District Hospital (about 1.9 miles north-west) to small clinics, depends on clean filters, coils and ducts. For schools like Lyminster Primary School, the holidays are the usual time to inspect and clean ventilation.

Nearby you will also find Arundel and District Hospital (1.9 miles north-west) and Rustington Museum (2.3 miles south-east). Open spaces near Lyminster include Highdown Hill and WWT Arundel.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s simpler to plan the work at Lyminster now than to arrange it in a hurry later.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

The process
Protection comes first: 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 one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. We agree a date with you, plan the drive to Lyminster and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids

Managing agents and facilities teams in Lyminster
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Travel, parking and unloading
- What state the system is in
- One-off work versus a regular cycle
- How big the system is
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Wide photos of the system and the area around it
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
