AHU cleaning across Black Notley

The process

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to Black Notley run smoothly.

  1. We survey the unit from photos or on site and agree what’s included.
  2. The unit is shut down with your site team and the area protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. You get a TR19® certificate and a photo report.

How to prepare

  • Let us know about permits to work or site inductions
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Plan for cooking equipment or plant to be off before we arrive

About our AHU cleaning in Black Notley

Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have leaves and litter drawn into the unit and dirty fans and fan housings, we can help.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.

Think of the report as the 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, ready for your insurer.

What the work involves, part by part

Heating and cooling coils

Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.

Drain trays

Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.

Keeping the system healthy

How long the results last depends on use and care. Here’s what we suggest:

  • Keep the certificate and photo report with the plant records
  • Report musty smells from the vents right away
  • Clear leaves and litter away from the intake
  • Plan the next inspection before the last report gets filed away

The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.

Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Why deal with it now?

Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s worth booking a check, because nobody sees inside a duct day to day.

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Why book with us

  • Out-of-hours work and a 24/7 emergency line
  • A single point of contact for sites across the South East and London
  • Trading since 2009
  • Each visit written up, with pictures

AHU cleaning in Black Notley: local notes

There are about 5 schools, colleges and universities and about 4 hospitals, care homes and childcare premises on the FSA’s food hygiene register within roughly a mile and a half of the centre of Black Notley. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. William Julien Courtauld Hospital is the nearest hospital, about 1.8 miles north-west of Black Notley. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. About 37 miles out from central London, Black Notley is part of the South East area we work across. Evening, overnight and weekend visits are all possible.

Classrooms and halls at schools such as Braintree Sixth Form are easiest to work in when pupils are away. Healthcare ventilation, from large hospitals like William Julien Courtauld Hospital (about 1.8 miles north-west) to small clinics, depends on clean filters, coils and ducts.

Black Notley: your questions answered

Do you clean school ventilation in Black Notley in the holidays?

Yes, and it’s the easiest time to do it. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Black Notley. Booking early in the term gives the best choice of holiday dates.

Can you get to a site in Black Notley?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

Do you have a 24/7 line?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.

Do you offer maintenance contracts?

Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.

Can you fix a faulty AHU?

The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.

Are you insured?

Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

How much notice should we give?

Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

Will the ventilation be off while you clean?

Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.

What we are called out for in Black Notley

No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.

Any of these means the system needs a check-up:

  • Fan sections that haven’t been cleaned in years
  • Dirty filters cutting the airflow
  • Stale or musty smells from the ventilation
  • Drain trays holding standing water

If you manage shops or offices close to Cressing station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What to look for in a quote

  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether a written report and pictures are included
  • When they can work, and whether that’s outside your opening hours
  • Whether they’re fully insured
