How we handle AHU cleaning in Hearnden Green
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. If you have dust-coated heating and cooling coils and units needing a clean before a new tenant or handover, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

How the job changes from site to site
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.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
When to call us in Hearnden Green
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
- Units that have only ever had filter changes
- Units needing a clean before a new tenant or handover
For sites in and around Hearnden Green, the units and the ductwork are both looked at.
What your quote should include
- Whether the figure could change on the day
- What paperwork you get at the end
- Whether the work can be done while the site is closed
- What insurance they carry
Managing agents and facilities teams in Hearnden Green
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Planning a trip to Hearnden Green ahead is easier for everyone than a rushed one.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

How the visit works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a village like Hearnden Green are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Yes. We work evenings, overnight and at weekends. It means the site in Hearnden Green keeps running as normal. Tell us your opening hours when you ask for a quote.

Yes. Hearnden Green is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
