Air handling unit cleaning in Blean, Kent
AHU cleaning for Blean, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
AHU cleaning in Blean
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers drain trays, heating and cooling coils and supply and extract fans, and people most often call us about plant that needs cleaning after a refit and condensate trays that won’t empty.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The paperwork matters as much as the work. You get a written report with pictures after every visit, 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.

What affects the quote in Blean
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
- The times the site is available
- The size of the system
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises

Ventilation in Blean buildings
Food Standards Agency data includes about 10 schools, colleges and universities and about 6 care, childcare and hospital premises within roughly a mile and a half of the centre of Blean. Busy, occupied buildings like these are where clean supply air matters most. About 51 miles out from central London, Blean is part of the South East area we work across. The visit is fixed around your opening hours, not ours. About 2.4 miles south-east of Blean is Eastbridge Hospital of St Thomas the Martyr, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as Blean Primary School are usually done in the holidays, so classrooms are not disturbed. If you run a surgery, dental practice or care home near Blean, clean ventilation matters as much to you as to a hospital like Eastbridge Hospital of St Thomas the Martyr (about 2.4 miles south-east).

What AHU cleaning can’t fix
We won’t sell you work that does not address the problem, so here are the limits:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
Where we work
- Filter sections
- Supply and extract fans
- Drain trays
- Internal panels
- Dampers and louvres
- Heating and cooling coils
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Blean simpler. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
Why book with us
- Out-of-hours work and a 24/7 emergency line
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Photo reports with every job
- Fixed quotes from a survey or pictures
Aftercare tips
Once we’ve finished, these simple steps help:
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Blean: your questions answered
Can you work in Blean outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Will you come out to Blean?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or send us an email with the site type, opening hours and a few pictures.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we’ll ask.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Does the AHU have to be shut down for cleaning?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Blean can be planned properly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about parking and loading
- Move anything stored near the system
Ask for a quote
To get a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We usually come back within one working day.

We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
