AHU cleaning in Stonegate
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers dampers and louvres, heating and cooling coils and supply and extract fans, and the jobs we see most are stale or musty smells from the ventilation and filters that are clogged or overdue.
Somewhere as small as Stonegate, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
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.

Related advice
When to call us in Stonegate
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for these warning signs:
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
- Units that have only ever had filter changes
For schools like Stonegate Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether a written report and pictures are included
- Proof of insurance
- Whether a survey comes first
- How VAT is shown on the quote
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Why act early in Stonegate
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Equipment tucked in a roof space or outbuilding near Stonegate rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Staff cleaning versus specialist work
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, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Your questions about AHU cleaning in Stonegate
Can you come to Stonegate after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Stonegate needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Do you cover Stonegate for AHU cleaning?
Yes. We work across London and the South East, and Stonegate is part of that. To start, give us a ring on 0345 646 2711 or drop us a line with a few pictures of the system.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.
How long will the unit be out of action?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
Can you price the work without visiting?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we’ll say so.
