About our AHU cleaning in Densole
We clean air handling units for buildings in Densole and across Kent, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have odours coming through the supply air and dust-coated heating and cooling coils, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What we are called out for in Densole
Whatever surrounds a building in Densole, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
It’s time to book a visit if you see:
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Coils clogged with dust and debris
School buildings such as Hawkinge Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- Whether the price is fixed
- Whether VAT is included
- Proof of accreditation you can verify
- What’s included in the scope, part by part
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Densole, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Mention any parking or loading restrictions
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time

Advice
Managing agents and facilities teams in Densole
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Between visits
So the system stays in good health:
- Do not store bins or materials near the intake
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Fixed quotes for AHU cleaning in Densole
A fixed price needs a few facts first. We look at:
- The condition we find in the survey
- How easy every part is to reach
- Parking and loading at the site
- A single visit or a regular plan
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
For AHU cleaning in Densole, give us a ring on 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Common questions in Densole
Can the work in Densole be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Densole keeps running as normal. Tell us your opening hours when you ask for a quote.
Is Densole within the area you cover?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What if parts of the system can’t be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Do you have insurance?
Yes. We’re fully insured, and the details are available on request.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Leave it or put it right?
If people in a building in Densole complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Rural sites can’t always move to another kitchen or room when something fails.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
