How we handle AHU cleaning in Brent Cross

Where a building in Brent Cross has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Typical jobs include debris and leaves in the fresh air intake and stale or musty smells from the ventilation, across supply and extract fans, heating and cooling coils and dampers and louvres.

London buildings tend to keep their plant on the roof or below ground, so work in Brent Cross is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.

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.

What happens on the day

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. Night and weekend working is normal for us in London, and a site in Brent Cross is no exception.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. We close up the unit and send the certificate and before and after pictures.

Getting ready for the visit

  • Agree a time when the area can be out of use
  • Make sure someone can let us in and lock up afterwards
  • Tell us where we can park and unload

Why deal with it now?

Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. It’s better booked as a planned job in Brent Cross than handled as an emergency.

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 will price it together.

Why book with us

  • A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
  • One contact for all your sites in London and the South East
  • Out-of-hours work and a 24/7 emergency line
  • Full insurance on every job

What affects the quote in Brent Cross

Every site gets its own quote. This is what makes a difference:

  • Any permits to work or inductions
  • Whether it’s a one-off visit or part of a schedule
  • Travel, parking and unloading
  • The condition we find in the survey

You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

What to send for a quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • Problems your staff have spotted
  • Detail shots of panels, filters and grilles
  • Any previous report or certificate
  • The times we could work without disrupting the site

Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What your team can do, and what needs us

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Part by part

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.

Heating and cooling coils

Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.

When something else is needed

Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:

  • Airflow problems caused by the system’s design
  • Dirty ducts beyond the unit itself
  • Faulty motors, drives or bearings

If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think.

What the work covers

  • Filter sections
  • Dampers and louvres
  • Supply and extract fans
  • Internal panels
  • Heating and cooling coils
  • Drain trays

Questions from Brent Cross

Is parking a problem for work in Brent Cross?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.

Do you do school ventilation cleaning in Brent Cross in the summer holidays?

Yes. The holidays are the usual time for school work. There are about 49 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Brent Cross. Send us your term dates when you ring 0345 646 2711 or send us an email, and we will fit the work in.

Which parts of an air handling unit do you clean?

Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.

Do you work evenings or weekends?

Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.

Will you repair the fan or motor?

AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.

How long does it take to clean an air handling unit?

Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.

Can we book visits on a schedule?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.

What is TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Multi-site and managed buildings

When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.

From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
