How we handle AHU cleaning in Grahame Park
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. Typical jobs include dust-coated heating and cooling coils and dirty fans and fan housings, across internal panels, dampers and louvres and drain trays.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Grahame Park, as elsewhere, cleaning starts with an inspection of what’s there.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Once we have finished, these simple steps help:
- Report water on the plant room floor
- Book the next check in line with the report
- Don’t store bins or materials near the intake
- Flag stale or damp smells in the supply air
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

Other services in Grahame Park
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Signs you need AHU cleaning in Grahame Park
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
If you manage offices or shops near Mill Hill Broadway station, their ventilation can be inspected and cleaned out of hours.
Questions to ask before you book
- Whether the figure could change on the day
- How VAT is shown on the quote
- Exactly which parts of the system are covered
- When they can work, and whether that’s outside your opening hours
Your questions about AHU cleaning in Grahame Park
Can a school’s ventilation in Grahame Park be done out of term time?
Yes, out-of-term visits are normal for schools. With about 44 schools and colleges on the FSA’s register within roughly a mile and a half of Grahame Park, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we’ll fit the work in.
Is parking a problem for work in Grahame Park?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Honest limits
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think before you book.

What happens on the day
A visit follows the same order every time: protect the area, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. In a London area like Grahame Park, parking, loading and building access are planned before the day of the work.
- 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.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
- Dig out any earlier paperwork for the system

Part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
