AHU cleaning in Linford
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers drain trays, dampers and louvres and supply and extract fans, and people most often call us about debris and leaves in the fresh air intake and condensate trays that won’t empty.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Linford.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload

What staff can safely do
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 can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Fixed quotes for AHU cleaning in Linford
The diagnosis comes before the price. The main factors are:
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
- Parking and loading at the site
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What we need to know
When you contact us, these details help:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, call us on 0345 646 2711, or send details by email.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. If the system at a site near Linford fails, there may be nowhere nearby to move to.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
What you get with us
- Survey first, then a fixed quote
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Trading since 2009
- Fixed quotes, normally within one working day
Do you need AHU cleaning in Linford?
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
It’s time to book a visit if you see:
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
Wherever a school like East Tilbury Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
- Don’t ignore odours coming through the grilles
- Watch for drips or damp patches near the plant
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
