Between visits

To keep the system working properly between visits:

  • Do not ignore odours coming through the grilles
  • Keep the area around the fresh air intake clear
  • Check the drain tray is emptying during routine visits
  • Keep the certificate and photo report with the plant records

Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.

Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

How we handle AHU cleaning in Ringlestone

Our AHU cleans for sites in Ringlestone cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers drain trays, supply and extract fans and heating and cooling coils, and people most often call us about blocked condensate drains and slimy trays and stale or musty smells from the ventilation.

Around a place like Ringlestone, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.

Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How the visit works

There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. In a place like Ringlestone, we fit the visit around your 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. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

How to prepare

  • Name a contact who can let us in at the agreed time
  • Mention any locked doors, roof access or ceiling voids
  • Have your last certificate or report to hand

How to get a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711 or send us an email.

Landlords, agents and facilities managers

We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.

  • Drain trays
  • Dampers and louvres
  • Heating and cooling coils

What affects the cost of AHU cleaning

Some jobs are bigger than they look, and some smaller. The main factors:

  • A single visit or a regular plan
  • Parking and loading at the site
  • When the work can happen, such as evenings, overnight or weekends
  • The condition we find in the survey

Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before we start.

Asking for a quote

A few details help us quote accurately. When you get in touch, it helps to send:

  • The roof, plant room or outside wall the system runs to
  • Your opening hours and when the area is out of use
  • Any previous report or certificate
  • The site address and the type of premises

Common problems we fix in Ringlestone

Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.

Clients usually contact us when they notice one of these:

  • Fan sections that haven’t been cleaned in years
  • Plant that has been serviced but not cleaned
  • Dirty filters cutting the airflow
  • Intake sections clogged with outdoor debris

School buildings such as North Borough Junior School are normally done in the holidays, so classrooms are not disturbed.

Questions to ask before booking

  • Whether the quote shows VAT
  • Whether a survey comes first
  • Whether the whole system is included, or only the parts that are easy to reach
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

How to choose an extract cleaning contractor

What the work involves, 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 the housing around them is cleaned too.

Fans and fan sections

Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.

Ringlestone questions

Do you cover smaller places like Ringlestone?

Yes. Ringlestone is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.

Do you clean school ventilation in Ringlestone in the holidays?

Yes. The holidays are the usual time for school work. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ringlestone. Tell us your holiday dates and we’ll book the visit for when the site is empty.

How long does it take to clean an air handling unit?

It takes one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.

What do you do with what you remove?

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.

Do you offer maintenance contracts?

Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.

How much does AHU cleaning cost?

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

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

What about areas you cannot get to?

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.
