How we handle AHU cleaning in Puddledock

If the units serving a building in Puddledock have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers heating and cooling coils, dampers and louvres and drain trays, and common reasons people get in touch are blocked condensate drains and slimy trays and odours coming through the supply air.

For a building in or near Puddledock, access is agreed in advance and the visit is planned around the journey.

Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Puddledock buildings and their air

Going by the FSA’s register, there are about 11 schools, colleges and universities and about 16 care, childcare and hospital premises serving food within 1.5 miles or so of the middle of Puddledock. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Puddledock’s nearest hospital, West Hill Hospital, is about 2.5 miles north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. We cover Puddledock, about 13 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.

Wherever a school like Hextable Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Different parts, different methods

Filters

Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.

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.

The process

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like Puddledock, lanes, gates and parking are worth mentioning in advance.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  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. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

Preparing for the visit

  • Dig out any earlier paperwork for the system
  • Make sure someone can let us in and lock up afterwards
  • Allow time for equipment near the work to be turned off and cool down

For landlords and multi-site operators

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building around the people who use them.

What a clean won’t put right

In fairness, some problems need a different fix:

  • Ventilation that was badly designed in the first place
  • Mechanical faults with motors, belts or bearings
  • The supply and extract ducts, quoted separately

If you are not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer before you book.

What the work covers

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

Why it’s worth doing now in Puddledock

Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. A planned visit to Puddledock is easier to arrange than an emergency callout.

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.

Why book with us

  • We are fully insured
  • Ventilation hygiene specialists since 2009
  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • Photo reports with every job

What we’re called out for in Puddledock

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.

Look out for these warning signs:

  • Air handling units due a clean after building work
  • Stale or musty smells from the ventilation
  • Plant that has been serviced but not cleaned
  • Filters that are clogged or overdue

West Hill Hospital, about 2.5 miles north-east, is the nearest hospital to Puddledock, and healthcare sites of every size need their supply air kept clean.

Questions to ask before booking

Puddledock questions

Do you cover smaller places like Puddledock?

Yes. Puddledock is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.

Can a school’s ventilation in Puddledock be done out of term time?

Yes, and it’s the easiest time to do it. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Puddledock. Booking early in the term gives the best choice of holiday dates.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

How long does an AHU clean take?

Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.

What’s included in an AHU clean?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.

What does AHU cleaning cost?

The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.

What is TR19?

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

Can you clean without disrupting the building?

Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.

What your team can do, and what needs us

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 send you a fixed quote.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
