About our AHU cleaning in East Dulwich

Where a building in East Dulwich has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. We are often asked to deal with units that have only ever had filter changes and air handling units with blocked filters, on heating and cooling coils, internal panels and supply and extract fans.

London buildings tend to keep their plant on the roof or below ground, so work in East Dulwich is often done in the evening or at weekends. Loading and parking are planned with the building first.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Landlords, agents and facilities managers

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

Ventilation in East Dulwich buildings

There are about 65 schools, colleges and universities, about 54 hospitals, care homes and childcare premises and about 5 hotels, B&Bs and guest houses on the FSA’s food hygiene register within about 1.5 miles of central East Dulwich. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. About within half a mile south-east of East Dulwich is Dulwich Community Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

Classrooms and halls at schools such as Dog Kennel Hill School are easiest to work in when pupils are away. Dulwich Community Hospital, about less than half a mile south-east, is the nearest hospital to East Dulwich, and healthcare sites of every size need their supply air kept clean.

Between visits

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

  • Plan the next inspection before the last report gets filed away
  • Don’t store bins or materials near the intake
  • Flag stale or damp smells in the supply air
  • Make sure condensate is draining away

Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.

Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.

What we do, step by step

Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Most London sites can’t stop for the day, so work in East Dulwich is usually done overnight, early in the morning or at weekends.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before photos of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After pictures are taken and the certificate issued.

Getting ready for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Clear the space around the work
  • Have your last certificate or report to hand

How to get a 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.

Advice

How the job changes from site to site

Drain trays

Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.

Filters

Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.

In-house cleaning or a specialist?

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

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

How we price AHU cleaning

We quote each job individually. This is what makes a difference:

  • Whether we need access equipment or extra panels
  • The condition we find in the survey
  • Where the site is and how we reach it
  • A single visit or a regular plan

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.

Asking for a quote

Photos and a few facts are often enough to price the work. Useful things to send:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Close-ups of filters, grilles, hatches or access panels
  • Photos showing the whole system and its surroundings
  • The paperwork from the last visit, if you have it

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Do you need AHU cleaning in East Dulwich?

No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.

Any of these means the system needs a check-up:

  • Air handling units due a clean after building work
  • Debris and leaves in the fresh air intake
  • Odours coming through the supply air
  • Filters that are clogged or overdue

Workplaces around East Dulwich station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Questions from East Dulwich

Can you clean school ventilation in East Dulwich during the holidays?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 65 schools, colleges and universities with registered kitchens within about a mile and a half of East Dulwich. Tell us your holiday dates and we’ll book the visit for when the site is empty.

What do you need to know about parking in East Dulwich?

London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

Is East Dulwich in your area?

Yes. East Dulwich is part of the area we cover, as part of our area across London and the South East.

Will you repair the fan or motor?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.

How often do AHUs need cleaning?

There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.

Do you look at the system first?

Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.

Will we get paperwork for the AHU clean?

Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
