AHU Cleaning in Upper Dicker
Professional AHU cleaning in and around Upper Dicker, timed so the site keeps working and signed off in writing with photos.
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Dust built up on fan impellers
Common problems we fix in Upper Dicker
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
What we’re most often called out for:
- Odours coming through the supply air
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
- Condensate trays that won’t empty
Hospitals such as Hellingly Hospital Railway (about 2.8 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Upper Dicker are no different.

AHU cleaning in Upper Dicker, done properly
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you have dust built up on fan impellers and plant that needs cleaning after a refit, we can put it right, from internal panels, dampers and louvres and heating and cooling coils onwards.
For a building in or near Upper Dicker, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

FAQs for Upper Dicker
Can you get to a site in Upper Dicker?
Yes. Upper Dicker is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is AHU cleaning available in Upper Dicker?
Yes. We work across London and the South East, and Upper Dicker is part of that. Just give us a ring on 0345 646 2711 or send us an email with a few details of the site.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
How long does it take to clean an air handling unit?
The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can give us a ring on 0345 646 2711, or email photos to plan it.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. If you can send photos, we can arrive in Upper Dicker knowing what to expect.
- We look at the unit and the plant area during the survey.
- 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.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Related advice
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. It’s worth booking a check, because nobody sees inside a duct day to day.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- The times the site is available
- Whether several sites go on one quote
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Aftercare tips
Once we’ve finished, these simple steps help:
- Don’t store bins or materials near the intake
- Report musty smells from the vents straight away
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
