Dormers Wells AHU cleaning
AHU cleaning for Dormers Wells, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site to keep disruption down.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
AHU cleaning in Dormers Wells, done properly
We clean air handling units for buildings in Dormers Wells and across Greater London, 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. Common call-outs are for intake sections clogged with outdoor debris and air handling units due a clean after building work, on heating and cooling coils, internal panels and dampers and louvres.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Dormers Wells, as elsewhere, cleaning starts with an inspection of what’s there.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Check the drain tray is emptying during routine visits
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Your questions about AHU cleaning in Dormers Wells
Can you work in Dormers Wells outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Dormers Wells doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Can you clean school ventilation in Dormers Wells during the holidays?
Yes. The holidays are the usual time for school work. Around Dormers Wells, the Food Standards Agency lists about 45 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How long does it take to clean an air handling unit?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
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 will take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Every month a London system goes without attention adds to what has to be done later.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or use the quote form, and we’ll talk you through it.

The nearest hospital to Dormers Wells is St Bernard's Hospital, about 0.9 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Dormers Wells.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Name a contact who can let us in at the agreed time
- Move anything stored near the system
- Mention any parking or loading restrictions
How to get a quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711 or drop us a line.
Advice
What else we do in Dormers Wells
What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It’s based on:
- Any permits to work or inductions
- How easy every part is to reach
- One-off work versus a regular cycle
- The times the site is available
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
