What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
AHU cleaning in Noak Hill, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. Typical jobs include condensate trays that won’t empty and dirty coils holding back the airflow, across dampers and louvres, supply and extract fans and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Noak Hill
Food Standards Agency data includes about 11 schools, colleges and universities and about 22 care, childcare and hospital premises in and around Noak Hill, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Harold Wood Hospital is the nearest hospital, about 1.9 miles south of Noak Hill.

The visit is fixed around your opening hours, not ours.

What a clean won’t put right
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Building management system faults
- Airflow problems caused by the system’s design
If in doubt, call 0345 646 2711 or send us an email and we will say what we think.
Where we work
- Drain trays
- Internal panels
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Noak Hill simpler. In a place like Noak Hill, ductwork and fans are easy to forget until something goes wrong.
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 talk you through it.

Signs you need AHU cleaning in Noak Hill
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
The symptoms we are asked about most include:
- Dirty filters cutting the airflow
- Drain trays holding standing water
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
If you manage a school such as Drapers' Pyrgo Priory School, ventilation cleaning is best booked for the holidays.

What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Noak Hill, 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.
- We take after pictures and issue the certificate and report.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Let us know about permits to work or site inductions

Noak Hill: your questions answered
Do you work at weekends in Noak Hill?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Is Noak Hill within the area you cover?
Yes, we work in villages as well as towns, and Noak Hill is covered. Just mention lanes, gates or anything else about the site when you book.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
How often do AHUs need cleaning?
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.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Noak Hill and across Essex. Work can be phased by floor, building or site to keep disruption down.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
