About our AHU cleaning in East Langdon
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. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Common call-outs are for stale or musty smells from the ventilation and filters that are clogged or overdue, across internal panels, drain trays and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Questions from East Langdon
Is East Langdon within the area you cover?
Yes. East Langdon is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do you work overnight in East Langdon?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
When should our AHU next 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.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
In-house cleaning or 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.
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. Cleaning inside ducts and units is specialist work.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- The number of sites or systems
- How big the system is
- A single visit or a regular plan
- The condition we find in the survey
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- When the site is open and when it’s quiet
Need a price for AHU cleaning? Please give us a ring on 0345 646 2711, or email photos with a few details about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
Honest limits
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- A system that’s undersized for the building
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before booking.
Parts of the system we cover
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Internal panels
- Drain trays
What we’re called out for in East Langdon
Whatever surrounds a building in East Langdon, 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.
The symptoms we’re asked about most are:
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
- Drain trays holding standing water
- Dirty coils holding back the airflow
Healthcare buildings such as Royal Victoria Hospital, about 2.9 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near East Langdon, yours matters too.
Comparing quotes
- Whether a survey comes first
- Whether inaccessible sections are listed on the report
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of accreditation you can verify
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Equipment tucked in a roof space or outbuilding near East Langdon rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
