AHU cleaning in South Town, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers filter sections, drain trays and internal panels, and people most often call us about fan sections that haven’t been cleaned in years and units that have only ever had filter changes.
For a building in or near South Town, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can you clean the ducts connected to the AHU?

It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to 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’ll take a look and give you a fixed quote.
Fixed quotes for AHU cleaning in South Town
Your quote is based on your site. We consider:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
To speed up the quote, send us:
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What else we do in South Town
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like South Town, lanes, gates and parking are worth mentioning in advance.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Clear the space around the work
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
Related advice
Honest limits
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It does not solve:
- Faulty motors, drives or bearings
- A system that’s undersized for the building
- Controls and BMS settings that run the unit
If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.
Parts of the system we cover
- Filter sections
- Internal panels
- Heating and cooling coils
- Drain trays
- Dampers and louvres
- Supply and extract fans
Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
What we are called out for in South Town
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
What we’re most often called out for:
- Air handling units due a clean after building work
- Units that have only ever had filter changes
- Drain trays holding standing water
- Coils clogged with dust and debris
School buildings such as Medstead Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.
