AHU cleaning in Bitchet Green, done properly

No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. We’re often asked to deal with odours coming through the supply air and dust built up on fan impellers, on drain trays, internal panels and heating and cooling coils.

In a village or hamlet like Bitchet Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Common questions in Bitchet Green

Is Bitchet Green in your area for AHU cleaning?

Yes, Bitchet Green is within the area we cover across London and the South East. A fixed quote normally follows within one working day of the survey details.

Do you work at weekends in Bitchet Green?

Yes, out-of-hours work is a big part of what we do. It means the site in Bitchet Green keeps running as normal. Let us know the hours you are closed and we’ll book within them.

Will we get paperwork for the AHU clean?

Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

What’s included in an AHU clean?

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

When should our AHU next be cleaned?

There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.

What does AHU cleaning cost?

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

What affects the cost of AHU cleaning

Every site gets its own quote. These are the things that affect it:

  • Any permits to work or inductions
  • The condition we find in the survey
  • How big the system is
  • Whether it’s a one-off visit or part of a schedule

No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Asking for a quote

To speed up the quote, send us:

  • When the site is open and when it’s quiet
  • The roof, plant room or outside wall the system runs to
  • Wide pictures of the system and the area around it
  • Where the site is and what kind of site it is

To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711, or email photos.

Why deal with it now?

Signs you need AHU cleaning in Bitchet Green

Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.

The symptoms we’re asked about most include:

  • Plant that needs cleaning after a refit
  • Dirty filters cutting the airflow
  • Fan sections that haven’t been cleaned in years
  • Debris and leaves in the fresh air intake

Healthcare buildings such as Sevenoaks Hospital, about 2.8 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Bitchet Green, yours matters too.

What to look for in a quote

  • Whether they recommend a next date
  • Whether the whole system is included, or only the parts that are easy to reach
  • When they can work, and whether that’s outside your opening hours
  • Which accreditations they hold, and whether you can check them

Choosing a duct cleaning contractor

Part by part

Fans and fan sections

Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.

Internal casing and panels

We open each section through its doors and close them securely when we’re done before the unit is handed back.

How it works

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Bitchet Green before we set off.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. We take after photos and issue the certificate and report.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Arrange a key holder or contact on site
  • Make sure equipment near the work can be switched off and left to cool

Ask for a quote

We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.

What AHU cleaning can’t fix

We will always give you a straight diagnosis, so here’s what this work can’t put right:

  • Ventilation that was badly designed in the first place
  • Ductwork downstream of the unit, which is a separate clean
  • Damaged coils beyond cleaning

If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

Where we work

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