AHU cleaning in Hoo St Werburgh

In-house cleaning or a specialist?

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

AHU cleaning in Hoo St Werburgh

Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for dust built up on fan impellers and air handling units never cleaned inside, on filter sections, internal panels and supply and extract fans.

Smaller buildings around Hoo St Werburgh often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Internal casing and panels

Hoo St Werburgh: your questions answered

Do you clean school ventilation in Hoo St Werburgh in the holidays?

Yes, holiday work suits schools best. Around Hoo St Werburgh, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Can you get to a site in Hoo St Werburgh?

Yes. Hoo St Werburgh is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Are you insured?

Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.

What’s TR19?

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

What happens if you can’t reach some of it?

They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

How much does AHU cleaning cost in Hoo St Werburgh?

It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711, or email photos and tell us about the site and its opening hours.

Do you need to switch the unit off?

Yes, for the time we are working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.

Is a quote from photos possible?

Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.

Looking after it afterwards

To keep the system working properly between visits:

  • Diary the inspection date recommended in the report
  • Note any water around the unit or leaks below it
  • Flag stale or damp smells in the supply air
  • Stick to the filter change plan

Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.

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

What AHU cleaning cannot fix

We will not sell you work that does not address the problem, so here are the limits:

  • Breakdowns that need a mechanical engineer
  • Controls and BMS settings that run the unit
  • Ductwork downstream of the unit, which is a separate clean

Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.

Parts of the system we cover

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

What happens on the day

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. In a smaller place like Hoo St Werburgh, 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. The area is protected and the unit made safe.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Before we arrive

  • Mention any locked doors, roof access or ceiling voids
  • Let us know about parking and loading
  • Tell us the best time to work, such as after service or at a weekend

Ask for a quote

Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

What affects the cost of AHU cleaning

Sites vary more than people expect. What affects the quote:

  • Access, including roofs, risers and ceiling voids
  • Site rules, permits and inductions
  • What state the system is in
  • Parking and loading at the site

What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

What we need to know

Photos let us diagnose from a distance. The most useful are:

  • Problems your staff have spotted
  • Any previous report or certificate
  • The roof, plant room or outside wall the system runs to
  • Photos showing the whole system and its surroundings

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Signs you need AHU cleaning in Hoo St Werburgh

An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.

What we are most often called out for:

  • Coils clogged with dust and debris
  • Fan sections that haven’t been cleaned in years
  • Filters that are clogged or overdue
  • Odours coming through the supply air

Hospitals such as Medway Maritime Hospital (about 3.2 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Hoo St Werburgh are no different.
