About our AHU cleaning in Aldersbrook
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers filter sections, internal panels and supply and extract fans, and the jobs we see most are condensate trays that won’t empty and filters that are clogged or overdue.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Aldersbrook, dust settles in the units and ducts year after year.
The paperwork matters as much as the work. Each visit is written up with photos, 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 ready for an insurer, fire officer or EHO.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Before any visit in Aldersbrook, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- 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.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Quotes are quick. 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.
Advice
What affects the quote in Aldersbrook
We do not publish a price list, because sites vary so much. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- The scale of the work
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Any access panels or hatches you can see
- Your last certificate, test record or report
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.
When something else is needed
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Dirty ducts beyond the unit itself
- Building management system faults
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.
What the work covers
- Internal panels
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
Leave it or put it right?
If people in a building in Aldersbrook complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Leaving it on a busy London site only adds to the work.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

What we are called out for in Aldersbrook
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Most sites get in touch after spotting one of these:
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
- Intake sections clogged with outdoor debris
Classrooms and halls at schools such as Aldersbrook Primary School are easiest to work in when pupils are away.
Before you book anyone
- Whether the work can be done while the site is closed
- How VAT is shown on the quote
- Whether they recommend a next date
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Aldersbrook: your questions answered
Does London parking affect a job in Aldersbrook?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, typically makes it simpler.
Can ventilation in schools around Aldersbrook be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 32 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Aldersbrook. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Is a quote from pictures possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
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.
