AHU cleaning in North End
Our AHU cleans for sites in North End cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers internal panels, dampers and louvres and filter sections, and common reasons people get in touch are air handling units with blocked filters and dust built up on fan impellers.
Somewhere as small as North End, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
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’ll take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
North End buildings and their air
About 32 miles out from central London, North End is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Broomfield Hospital is the nearest hospital, about 5.2 miles south-east of North End. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
North End: your questions answered
Is North End within the area you cover?
Yes, North End is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can the work in North End be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
How long does an AHU clean take?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so phone us on 0345 646 2711 or send us an email to talk it through.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Why act early in North End
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Rural sites can’t always move to another kitchen or room when something fails.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to North End.
- 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.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions

Advice
Part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
