AHU cleaning in Henley Street, done properly
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, internal panels and drain trays, and the jobs we see most are drain trays holding standing water and dirty filters cutting the airflow.
Somewhere as small as Henley Street, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The report is your 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.

What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
What we need to know
To help us quote quickly, send us:
- Wide pictures of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

When to call us in Henley Street
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch after spotting something like this:
- Dust-coated heating and cooling coils
- Blocked condensate drains and slimy trays
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
School buildings such as Cobham Primary School are normally done in the holidays, so classrooms are not disturbed.
Questions to ask before you book

Henley Street questions
Can you work in Henley Street outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Do you work in villages like Henley Street?
Yes. Henley Street is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Is a quote from pictures possible?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If photos are not enough, we’ll survey first.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How much does AHU cleaning cost in Henley Street?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll normally reply within one working day.
How long does an AHU clean take?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so call 0345 646 2711 or send us an email to talk it through.

We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Looking after it afterwards
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Note any water around the unit or leaks below it
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What AHU cleaning can’t fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Breakdowns that need a mechanical engineer
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.
