AHU cleaning across Prestonville

AHU cleaning for kitchens and businesses in Prestonville

We clean air handling units for buildings in Prestonville and across Brighton and Hove, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include dust-coated heating and cooling coils and fan sections that haven’t been cleaned in years, across internal panels, heating and cooling coils and supply and extract fans.

For a building near Prestonville, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.

We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What your team can do, and what needs us

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.

Aftercare tips

No system stays clean for ever, but care slows the build-up. A few tips:

  • Flag stale or damp smells in the supply air
  • Stick to the filter change plan
  • Make sure condensate is draining away
  • Keep the certificate and photo report with the plant records

If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

How the visit works

On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes one overnight shift for many single units, with bigger plant phased. In a smaller place like Prestonville, parking is rarely the issue, but tell us about gates, roof access and opening hours.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. We close every panel, hand the unit back and send the report and certificate.

Preparing for the visit

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Have your last certificate or report to hand
  • Make sure someone can let us in and lock up afterwards

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Related advice

When to call us in Prestonville

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.

If you notice any of these, it’s worth a diagnosis:

  • Plant that has been serviced but not cleaned
  • Rooms that smell stuffy when the system runs
  • Condensate trays that won’t empty
  • Dust built up on fan impellers

For schools like Stanford Infant School, the holidays are the usual time to inspect and clean ventilation.

What your quote should include

  • When they can work, and whether that’s outside your opening hours
  • What’s included in the scope, part by part
  • What paperwork you get at the end
  • Whether VAT is included

Our hiring checklist

Landlords, agents and facilities managers

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

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 photos.

What AHU cleaning cannot fix

Before booking, it helps to know what’s not included:

  • Ductwork downstream of the unit, which is a separate clean
  • Coils that are corroded or leaking and need replacing
  • Airflow problems caused by the system’s design

If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

Parts of the system we cover

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

AHU cleaning in Prestonville: local notes

Going by the FSA’s register, there are about 58 schools, colleges and universities, about 108 caring premises (care homes, nurseries and hospitals) and about 51 hotels and B&Bs serving food in and around Prestonville, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Montefiore Hospital is the nearest hospital, about less than half a mile south-west of Prestonville. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Prestonville is about 46 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.

Healthcare ventilation, from large hospitals like Montefiore Hospital (about less than half a mile south-west) to small clinics, depends on clean filters, coils and ducts. If you manage shops or offices close to Preston Park station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Questions from Prestonville

Can you come to Prestonville after we close?

Yes, out-of-hours work is a big part of what we do. It means the site in Prestonville keeps running as normal. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.

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

Yes. Half-terms and the summer break are the natural time for school work. With about 58 schools and colleges on the FSA’s register within roughly a mile and a half of Prestonville, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

How much notice should we give?

The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.

Do you offer maintenance contracts?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.

What’s included in an AHU clean?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.

How long does an AHU clean take?

Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so call us on 0345 646 2711 or send us an email to talk it through.

Are you insured?

Yes. We carry full insurance, and we’ve been trading since 2009.

Do you work with multi-site operators?

Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.

Part by part

Filters

Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.

Heating and cooling coils

Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
