The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Green Hailey, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in

Advice
AHU cleaning in Green Hailey
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, internal panels and heating and cooling coils, and common reasons people get in touch are stale or musty smells from the ventilation and condensate trays that won’t empty.
Work in a small place like Green Hailey starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

AHU cleaning around Green Hailey
The FSA’s food hygiene register lists about 4 schools, colleges and universities and about 4 hospitals, care homes and childcare premises with registered kitchens or food service in and around Green Hailey, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. For Green Hailey, the closest hospital is Chiltern Hospital, roughly 5.2 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Green Hailey, about 34 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Monks Risborough CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Signs you need AHU cleaning in Green Hailey
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
What we are most often called out for:
- Fan sections that haven’t been cleaned in years
- Units that have only ever had filter changes
- Drain trays holding standing water
- Stale or musty smells from the ventilation
Healthcare buildings such as Chiltern Hospital, about 5.2 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Green Hailey, yours matters too.

Questions from Green Hailey
Do you work in villages like Green Hailey?
Yes. Villages and rural sites across the South East are part of our work, Green Hailey included. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Green Hailey?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What about areas you can’t get to?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Do you clean the ductwork as well?
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.
When should our AHU next be cleaned?
That is 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.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Aftercare tips
To keep the system working properly between visits:
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Why it’s worth doing now in Green Hailey
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Systems in rural buildings are often out of sight and out of mind.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.

What the work involves, part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
