St Lawrence questions
Can you work in St Lawrence outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in St Lawrence keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Can you clean school ventilation in St Lawrence during the holidays?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of St Lawrence. Tell us your holiday dates and we will book the visit for when the site is empty.
How much notice do you need?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is a quote from photos possible?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
AHU cleaning in St Lawrence, done properly
If the units serving a building in St Lawrence 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. The work covers internal panels, filter sections and supply and extract fans, 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 St Lawrence starts with agreeing access and timings.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
AHU cleaning in St Lawrence: local notes
Food Standards Agency data includes about 5 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of St Lawrence. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Arthur Webster Memorial Hospital for Children is the nearest hospital, about 4.1 miles north-east of St Lawrence. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare buildings such as Arthur Webster Memorial Hospital for Children, about 4.1 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near St Lawrence, yours matters too.

Signs you need AHU cleaning in St Lawrence
Whatever surrounds a building in St Lawrence, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
What we are most often called out for:
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Blocked condensate drains and slimy trays
For schools like St Francis Catholic and Church of England Primary Academy, the holidays are the usual time to inspect and clean ventilation.

Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Planning a trip to St Lawrence ahead is easier for everyone than a rushed one.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

When something else is needed
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Mechanical faults with motors, belts or bearings
- The supply and extract ducts, quoted separately
- A system that is undersized for the building
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer.
Where we work
- Filter sections
- Heating and cooling coils
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Internal panels
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Store the TR19 paperwork where auditors can find it
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Diary the inspection date recommended in the report
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as St Lawrence, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
