How the job changes from site to site
Filters

Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
AHU cleaning in Ilmer, done properly
If the units serving a building in Ilmer have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for drain trays holding standing water and rooms that smell stuffy when the system runs, across heating and cooling coils, dampers and louvres and drain trays.
For a building in or near Ilmer, access is agreed in advance and the visit is planned around the journey.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Ilmer
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Look out for any of the following:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
School buildings such as Longwick Church of England Combined School are usually done in the holidays, so classrooms are not disturbed.
Before you book anyone
- If they look at the system before pricing
- How they set the interval to the next visit
- Whether the figure could change on the day
- How areas they can’t reach will be recorded
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. In a place like Ilmer, ductwork and fans are easy to forget until something goes wrong.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we will talk you through it.

The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Ilmer is set by you, and the travel is our side of the planning.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly.
What we work on in Ilmer
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Internal panels
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Common questions in Ilmer
Can you come to Ilmer after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Ilmer needn’t be disturbed. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Will you come out to Ilmer?
Yes, Ilmer is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
How long will the unit be out of action?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, out of hours if needed.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with photos where it helps.
How far ahead should we book?
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.
