How the job changes from site to site

Filters

Filter condition tells you a lot about the rest of the unit. We photograph them for the report.

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.

AHU cleaning for kitchens and businesses in Farmoor

An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers supply and extract fans, heating and cooling coils and internal panels, and people most often call us about blocked condensate drains and slimy trays and filters that are clogged or overdue.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When it’s something else

To be straight with you, there are a few things this work will not fix:

  • Faulty motors, drives or bearings
  • Ductwork downstream of the unit, which is a separate clean
  • Airflow problems caused by the system’s design

Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly before you book.

What we work on in Farmoor

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

Leave it or put it right?

A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. A planned visit to Farmoor is easier to arrange than an emergency callout.

The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

Why us?

  • Trading since 2009
  • Each visit written up, with pictures
  • We diagnose before we treat
  • Full insurance on every job

Looking after it afterwards

A little care between visits keeps the system in better shape. Our advice:

  • Plan the next inspection before the last report gets filed away
  • Keep the certificate and photo report with the plant records
  • Make sure the unit’s access doors open easily
  • Don’t store bins or materials near the intake

We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.

Change or clean filters on time. Once filters clog, dirt starts getting past them.

For landlords and multi-site operators

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.

What we do, step by step

The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Visits to a village like Farmoor are booked in advance, at a time that suits whoever runs the site.

  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.

Getting ready for the visit

  • Move anything stored near the system
  • Agree a time when the area can be out of use
  • Arrange a key holder or contact on site

How to get a quote

Some systems can be priced from photos; 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.

What affects the cost of AHU cleaning

You’ll get a fixed price before any work starts. It’s based on:

  • The condition we find in the survey
  • The size of the system
  • Whether we need access equipment or extra panels
  • Working hours and out-of-hours timing

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

What we need to know

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

  • Problems your staff have spotted
  • Detail shots of panels, filters and grilles
  • Where the site is and what kind of site it is
  • The paperwork from the last visit, if you have it

Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Then give us a ring on 0345 646 2711, or email photos.

Common questions in Farmoor

Do you clean school ventilation in Farmoor in the holidays?

Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Farmoor. Booking early in the term gives the best choice of holiday dates.

Do you work in villages like Farmoor?

Yes. Farmoor is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.

Is there a report after cleaning?

Yes, both a certificate and a report with photos. It includes a recommended date for the next check.

Are you insured?

Yes. We carry full insurance and have been trading since 2009.

Do you do ventilation duct cleaning too?

Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.

How do you protect the area?

By covering it before any work starts. We keep the work contained and leave the area clean.

Can you price the work without visiting?

Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.

Can you look after several sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
