AHU cleaning in Long Green: local notes
Food Standards Agency data includes about 9 schools, colleges and universities and about 8 hospitals, care homes and childcare premises in Long Green and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Long Green, about 39 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. For Long Green, the closest hospital is William Julien Courtauld Hospital, roughly 2 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run an office near Braintree Freeport station, its supply ductwork can gather dust for years before anyone looks inside. Hospitals such as William Julien Courtauld Hospital (about 2 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Long Green are no different. For schools like Cressing Primary School, the holidays are the usual time to inspect and clean ventilation.

How we handle AHU cleaning in Long Green
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We are often asked to deal with dirty fans and fan housings and rooms that smell stuffy when the system runs, across heating and cooling coils, supply and extract fans and drain trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. You get a written report with photos after each visit, 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 ready for an insurer, fire officer or EHO.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Why act early in Long Green
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. It’s worth booking a check, because nobody sees inside a duct day to day.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

Common questions in Long Green
Can a school’s ventilation in Long Green be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. There are about 9 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Long Green. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is Long Green within the area you cover?
Yes. Long Green 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.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What about areas you can’t get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or drop us a line.
When something else is needed
Some problems need a different service or another trade:
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
If you are not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer.

Advice
How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.
