- Condensate trays that won’t empty
- Odours coming through the supply air
- Plant that has been serviced but not cleaned
Between visits
Once we have finished, these simple steps help:
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
AHU cleaning in Wrabness
All the building’s air passes through the fan, 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. The work covers heating and cooling coils, internal panels and supply and extract fans, and people most often call us about units that have only ever had filter changes and condensate trays that won’t empty.
For a building in or near Wrabness, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common questions in Wrabness
Do you offer AHU cleaning in Wrabness?
Yes, Wrabness is within the area we cover across London and the South East. Get in touch with the details and we’ll arrange a survey.
Is Wrabness within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Wrabness included. Let us know about access, parking and anything unusual about getting there when you book.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What should I send you?
A short description and a few pictures plus the address and your hours. We will ask for anything else we need.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Can you price the work without visiting?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we will say so.
How much does AHU cleaning cost in Wrabness?
There’s no set price, as it 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.
Signs you need AHU cleaning in Wrabness
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Look out for any of the following:
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
Around Wrabness, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- Whether the work can be done while the site is closed
- Which accreditations they hold, and whether you can check them
- How they set the interval to the next visit
- Whether the whole system is included, or only the parts that are easy to reach

Part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
What happens if it’s left?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Equipment tucked in a roof space or outbuilding near Wrabness rarely gets looked at unless someone books it.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.

In a small place like Wrabness, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
