AHU cleaning in Gosfield

If the units serving a building in Gosfield 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. Common call-outs are for debris and leaves in the fresh air intake and blocked condensate drains and slimy trays, across dampers and louvres, heating and cooling coils and internal panels.

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

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.

What we do, step by step

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Gosfield, the journey is planned ahead and the visit arranged around the site’s hours.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. After pictures are taken and the certificate issued.

Before we arrive

  • Let us know when the site is closed or quiet
  • Have your last certificate or report to hand
  • Name a contact who can let us in at the agreed time

What your team can do, and what needs us

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

What AHU cleaning can’t fix

To be straight with you, some problems need a different fix:

  • Building management system faults
  • The supply and extract ducts, quoted separately
  • Airflow problems caused by the system’s design

If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think.

Parts of the system we cover

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

When to call us in Gosfield

Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.

Signs it’s time to call us include:

  • Dirty filters cutting the airflow
  • Air handling units never cleaned inside
  • Dirty fans and fan housings
  • Drain trays holding standing water

If you manage a school such as Gosfield Community Primary School, ventilation cleaning is best booked for the holidays.

  • When they can work, and whether that’s outside your opening hours
  • Whether the price is fixed

Our hiring checklist

Why act early in Gosfield

Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Rural sites can’t always move to another kitchen or room when something fails.

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Will you come out to Gosfield?

Yes. Villages and rural sites across the South East are part of our work, Gosfield included. Photos of the system and directions to the site help us plan the visit.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

Which parts of an air handling unit do you clean?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.

Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

What do you do with what you remove?

It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.

How much notice should we give?

Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.

Landlords, agents and facilities managers

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

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. Where responsibility is shared, records matter even more.

How the job changes from site to site

Heating and cooling coils

A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.

Fans and fan sections

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