About our AHU cleaning in Crystal Palace
The fan pushes every bit of air in the system, 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. Common call-outs are for odours coming through the supply air and filters that are clogged or overdue, on internal panels, filter sections and heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Crystal Palace, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common questions in Crystal Palace
Do you work at weekends in Crystal Palace?
Yes, out-of-hours work is a big part of what we do. The work in Crystal Palace can fit around your hours. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
Can parking be tricky for a job in Crystal Palace?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Can you price the work without visiting?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. If pictures aren’t enough, we will survey first.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call us on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
Are you insured?
Yes. We’re fully insured, and the details are available on request.

Why it’s worth doing now in Crystal Palace
Stuffy rooms and stale smells in a building in Crystal Palace can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A building in Crystal Palace may have flats or offices above and alongside, and a fault in the system can affect them too.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
Why book with us
- One contact for all your sites in London and the South East
- CHAS, SafeContractor and ISO 9001
- Fully insured
- Fixed quotes from a survey or photos
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- A system that’s undersized for the building
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
If in doubt, give us a ring on 0345 646 2711 or email us and we’ll say what we think.
Where we work
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Filter sections
- Internal panels
- Dampers and louvres
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Signs you need AHU cleaning in Crystal Palace
Whatever surrounds a building in Crystal Palace, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
For schools like Crystal Palace School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Whether a written report and photos are included
- What insurance they carry
- Whether the figure could change on the day
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Getting kit into a London building takes planning, so let us know where we can load and park in Crystal Palace.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
