About our AHU cleaning in Temple Dinsley
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 are not flattened. The work covers internal panels, dampers and louvres and supply and extract fans, and common reasons people get in touch are condensate trays that won’t empty and fan sections that haven’t been cleaned in years.
Work in a small place like Temple Dinsley starts with agreeing access and timings.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

FAQs for Temple Dinsley
Do you cover smaller places like Temple Dinsley?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean school ventilation in Temple Dinsley during the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Temple Dinsley. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we will fit the work in.
What is TR19?
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.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
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. After that, simply call 0345 646 2711, or send details by email.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What staff can safely do
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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
What we’re called out for in Temple Dinsley
Whatever surrounds a building in Temple Dinsley, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
What we are most often called out for:
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
Hospitals such as Lister Hospital (about 2.9 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Temple Dinsley are no different.

What else we do in Temple Dinsley
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. For a village or hamlet like Temple Dinsley, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Keeping the system healthy

You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
