AHU cleaning for kitchens and businesses in Hunton
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers supply and extract fans, internal panels and heating and cooling coils, and common reasons people get in touch are air handling units due a clean after building work and plant that has been serviced but not cleaned.
In a village or hamlet like Hunton, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

Questions from Hunton
Can you work in Hunton outside opening hours?
Yes, nights and weekends are routine for us. It means the site in Hunton keeps running as normal. Just call us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can you get to a site in Hunton?
Yes. Hunton 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.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends to keep disruption down.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.

How we price AHU cleaning
Your quote is based on your site. We consider:
- How easy every part is to reach
- One-off work versus a regular cycle
- The size of the system
- What state the system is in
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
What we need to know
There’s no need for technical detail. Just send:
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or send us an email.
Between visits
After the visit, a few habits help the work last:
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Hunton, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
What happens if it’s left?
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. Rural sites can’t always move to another kitchen or room when something fails.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

What staff can safely do
If your staff spot something 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’ll take a look and give you a fixed quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
