AHU cleaning in Ilford, done properly
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 dampers and louvres, internal panels and drain trays, and people most often call us about plant that needs cleaning after a refit and dirty coils holding back the airflow.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Ilford is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. We fit London jobs around the building rather than the other way round, so a visit in Ilford is usually out of hours.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work

Aftercare tips
How long the results last depends on use and care. We suggest:
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents straight away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Signs you need AHU cleaning in Ilford
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Signs it’s time to call us include:
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Units needing a clean before a new tenant or handover
If you run an office near Ilford station, its supply ductwork can gather dust for years before anyone looks inside.

FAQs for Ilford
Can you clean school ventilation in Ilford during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 43 schools, colleges and universities with registered kitchens within about a mile and a half of Ilford. You can call 0345 646 2711 or email us with the dates the site is empty.
Do you work overnight in Ilford?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
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 they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
