AHU cleaning for kitchens and businesses in Stonehills
If the units serving a building in Stonehills have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We are often asked to deal with filters that are clogged or overdue and plant that needs cleaning after a refit, across drain trays, supply and extract fans and internal panels.
For a building in or near Stonehills, 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.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Stonehills questions
Can the work in Stonehills be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Stonehills can fit around your hours. Your opening times are the first thing we ask for.
Do you work in villages like Stonehills?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711 or send us an email.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
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.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

What else we do in Stonehills
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Stonehills, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Planning a trip to Stonehills ahead is easier for everyone than a rushed one.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.

Common problems we fix in Stonehills
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
For schools like Fawley Infant School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- Proof of accreditation you can verify
- Whether the figure could change on the day
- Exactly which parts of the system are covered
- What hours they’ll be on site
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
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.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before you book.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Filter sections
- Supply and extract fans
