About our AHU cleaning in New Ash Green
We clean air handling units for buildings in New Ash Green and across Kent, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with coils clogged with dust and debris and odours coming through the supply air, we can help.
Somewhere as small as New Ash Green, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. We agree a date with you, plan the drive to New Ash Green and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Advice
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
What we’re called out for in New Ash Green
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
What we are most often called out for:
- Dust-coated heating and cooling coils
- Odours coming through the supply air
- Air handling units with blocked filters
- Drain trays holding standing water
Darent Valley Hospital, about 5.2 miles north-west, is the nearest hospital to New Ash Green, and healthcare sites of every size need their supply air kept clean.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- If the quote is a fixed price or an estimate
- When the next visit should be, and why
- What happens if part of the system cannot be accessed
New Ash Green questions
Is New Ash Green within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, New Ash Green included. Photos of the system and directions to the site help us plan the visit.
Can a school’s ventilation in New Ash Green be done out of term time?
Yes. The holidays are the usual time for school work. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of New Ash Green. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we will fit the work in.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Which parts of an air handling unit do you 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.
How much does AHU cleaning cost in New Ash Green?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What if parts of the system cannot be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.

What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to New Ash Green is calmer for everyone.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Keeping the system healthy
To keep the system working properly between visits:
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
- Diary the inspection date recommended in the report
- Watch for drips or damp patches near the plant
Keep filter changes on schedule between cleans, because good filters protect everything downstream. 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.
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
What a clean won’t put right
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It will not put right:
- Coils that are corroded or leaking and need replacing
- Building management system faults
- Breakdowns that need a mechanical engineer
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before you book.
