AHU cleaning for kitchens and businesses in Compton
Our AHU cleans for sites in Compton cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers dampers and louvres, supply and extract fans and drain trays, and the jobs we see most are odours coming through the supply air and drain trays holding standing water.
For a building in or near Compton, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The paperwork matters as much as the work. Each visit is written up with photos, 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.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Somewhere as small as Compton, losing a kitchen or building to a fault is felt by everyone who uses it.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

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. We clean the impeller, housing and surrounding section.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
FAQs for Compton
Do you do school ventilation cleaning in Compton in the summer holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of Compton. Just phone us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you work in villages like Compton?
Yes. Compton is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean without disrupting the building?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
How long does an AHU clean take?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends to keep disruption down.
When should our AHU next 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 AHU cleaning can’t fix
Before you book, it helps to know what’s not included:
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
Not sure which it is? You can call us on 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Internal panels
- Drain trays
Between visits
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Signs you need AHU cleaning in Compton
An overdue filter loads up with dirt, 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:
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
If you manage offices or shops near Shawford station, their ventilation can be inspected and cleaned out of hours.
Questions to ask before booking
- How areas they cannot reach will be recorded
- Which accreditations they hold, and whether you can check them
- What insurance they carry
- What paperwork you get at the end
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Compton and turn up when the site is quiet.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Tell us about site rules, permits or sign-in
How to get a quote
For a fixed quote, give us a ring on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.
Advice
Compton buildings and their air
There are about 7 schools, colleges and universities and about 6 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central Compton. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 2.8 miles north of Compton is Royal Hampshire County Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
For schools like Compton All Saints Church of England Primary School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Compton, clean ventilation matters as much to you as to a hospital like Royal Hampshire County Hospital (about 2.8 miles north).
