AHU cleaning for kitchens and businesses in Hethe
If the units serving a building in Hethe have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for dust built up on fan impellers and units that have only ever had filter changes, on supply and extract fans, internal panels and filter sections.
In a village or hamlet like Hethe, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
- Make sure the unit’s access doors open easily
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

What affects the quote in Hethe
A fixed price needs a few facts first. We look at:
- Working hours and out-of-hours timing
- The number of sites or systems
- Travel, parking and unloading
- The size of the system
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:

- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles

- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.

Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site around the people who use them.
Do you need AHU cleaning in Hethe?
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Odours coming through the supply air
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
School buildings such as Fringford Church of England Primary School are typically done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- If the quote is a fixed price or an estimate
- Whether a survey comes first
- What records you’ll receive afterwards
What the work involves, part by part
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.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Questions from Hethe
Can you get to a site in Hethe?
Yes, we work in villages as well as towns, and Hethe is covered. The journey is planned ahead, so a few details about the route help.
Do you work overnight in Hethe?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How long will the unit be out of action?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, and you can phone us on 0345 646 2711 or use the quote form to plan it.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
