What AHU cleaning looks like in Rush Green
Food Standards Agency data includes about 19 schools, colleges and universities and about 16 caring premises (care homes, nurseries and hospitals) within about 1.5 miles of central Rush Green. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Rush Green is about 21 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Rush Green’s nearest hospital, Hertford County Hospital, is about 2 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Hertford County Hospital (about 2 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Rush Green are no different. If you manage a school such as Wheatcroft Primary School, ventilation cleaning is best booked for the holidays.

AHU cleaning for kitchens and businesses in Rush Green
Where a building in Rush Green has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers drain trays, heating and cooling coils and filter sections, and common reasons people get in touch are plant that has been serviced but not cleaned and intake sections clogged with outdoor debris.
Work in a small place like Rush Green starts with agreeing access and timings.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How we price AHU cleaning
The price is fixed before any work begins. It takes into account:
- The times the site is available
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.
Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.
Where we work
- Drain trays
- Internal panels
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

What else we do in Rush Green
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Planning a trip to Rush Green ahead is easier for everyone than a rushed one.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Rush Green.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Agree a time when the area can be out of use
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool

What we’re called out for in Rush Green
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Keep an eye out for these warning signs:
- Odours coming through the supply air
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
If you run an office near Ware station, its supply ductwork can gather dust for years before anyone looks inside.

Questions from Rush Green
Do you cover smaller places like Rush Green?
Yes. Villages and rural sites across the South East are part of our work, Rush Green included. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in Rush Green in the holidays?
Yes, and it’s the easiest time to do it. There are about 19 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Rush Green. Tell us your holiday dates and we will book the visit for when the site is empty.
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 don’t leave it behind.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
