Kent · Air handling unit cleaning
Air handling unit cleaning in Keycol, Kent
Our technicians work in Keycol on air handling unit cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Leaves and litter drawn into the unit
- Condensate trays that will not empty
- Plant that needs cleaning after a refit
The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. Seeing the system in pictures first means the trip to Keycol can be planned properly.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
How to get a quote
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.

How we handle AHU cleaning in Keycol
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for dirty filters cutting the airflow and odours coming through the supply air, on heating and cooling coils, filter sections and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Keycol
The FSA’s food hygiene register lists about 9 schools, colleges and universities and about 16 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service across Keycol and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. We cover Keycol, about 35 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as Borden Church of England Primary School are easiest to work in when pupils are away. For buildings in and around Keycol, TR19® Air cleaning starts with an inspection.
Keycol is about 2 miles west of Sittingbourne, in Kent. We provide AHU cleaning for businesses, landlords and public buildings in Keycol and the rest of Kent. Our area takes in 922 places across Kent, large and small. Our Maidstone page covers sites nearby, about 9 miles away.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- How many systems or sites are involved
- How easy every part is to reach
- Site rules, permits and inductions
- How big the system is
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.
What to send for a quote
When you contact us, it’s useful to have:
- Any symptoms, from odd noises to smells or leaks
- Wide photos of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, call 0345 646 2711 or use the quote form.
Why act early in Keycol
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. With notice, the visit to Keycol can be fitted around your bookings and events.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What you get with us
- Survey first, then a fixed quote
- We are fully insured
- A written report with pictures after every visit
- CHAS and SafeContractor accredited, with ISO 9001

Keycol: your questions answered
Can you clean school ventilation in Keycol during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Keycol. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
Can you come to Keycol after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just phone us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
Can you quote from pictures?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711 or drop us a line with the site type, opening hours and a few pictures.
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
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 each one has its own record.
When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
- Building management system faults
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Where we work
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Drain trays
What your team can do, and what needs us
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 call for the right kit, training and safe access. Leave those to us.

Keeping the system healthy
So the system stays in good health:
- Make sure the unit’s access doors open easily
- Keep filter changes on time and recorded
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
Stick to the filter change schedule, 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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
