AHU cleaning in Withdean

AHU cleaning in Withdean, done properly

We clean air handling units for buildings in Withdean and across Brighton and Hove, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with plant that has been serviced but not cleaned and coils clogged with dust and debris, we can help.

In a place like Withdean, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Withdean questions

Do you do school ventilation cleaning in Withdean in the summer holidays?

Yes, and it’s the easiest time to do it. Food Standards Agency records list about 46 schools, colleges and universities with registered kitchens within about a mile and a half of Withdean. Booking early in the term gives the best choice of holiday dates.

Do you work overnight in Withdean?

Yes, out-of-hours work is a big part of what we do. That way a site in Withdean doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

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.

Is Withdean in your area?

Yes. Our area takes in London and the counties of South East England, and that includes Withdean.

Will you repair the fan or motor?

Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

What types of premises do you cover?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Multi-site and managed buildings

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Fixed quotes for AHU cleaning in Withdean

Before we fix a price, we need to know a few things. We look at:

  • A single visit or a regular plan
  • Site requirements such as sign-in and permits
  • The condition we find in the survey
  • Whether several sites go on one quote

You will not find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Helping us quote

What to send for a quote:

  • Close-ups of filters, grilles, hatches or access panels
  • The paperwork from the last visit, if you have it
  • Where the site is and what kind of site it is
  • When the site is open and when it’s quiet

To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.

What happens on the day

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Evenings, weekends or a closed day all work for a site in a place like Withdean.

  1. We survey the unit from pictures or on site and agree what’s included.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. We clean out the drain tray and make sure it drains.
  5. A TR19® certificate and photo report follow the clean.

How to prepare

  • Let us know about parking and loading
  • Mention any locked doors, roof access or ceiling voids
  • Mention any sign-in, permit or induction we need

Get a fixed quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Honest limits

AHU cleaning cannot fix everything, and we’ll tell you before any work starts. It won’t put right:

  • Coils that are corroded or leaking and need replacing
  • Faulty motors, drives or bearings
  • Airflow problems caused by the system’s design

If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer.

Where we work

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

Keeping the system healthy

A little care between visits keeps the system in better shape. We recommend:

  • Make sure the unit’s access doors open easily
  • File each AHU report in the maintenance log
  • Flag stale or damp smells in the supply air
  • Note any water around the unit or leaks below it

When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

How the job changes from site to site

Rooftop and plant room units

Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.

Fans and fan sections

Before the fan is touched, the unit is shut down and made safe in agreement with the site.
