What AHU cleaning can’t fix

In fairness, there are a few things this work will not fix:

  • Coils that are corroded or leaking and need replacing
  • Mechanical faults with motors, belts or bearings
  • Ductwork downstream of the unit, which is a separate clean

If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

AHU cleaning for kitchens and businesses in Windmill Hill

We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. We’re often asked to deal with dirty fans and fan housings and dust-coated heating and cooling coils, on heating and cooling coils, drain trays and internal panels.

For a building in or near Windmill Hill, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Windmill Hill knowing what to expect.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After pictures are taken and the certificate issued.

Before we arrive

  • Tell us where we can park and unload
  • Plan for cooking equipment or plant to be off before we arrive
  • Clear the space around the work

What the work involves, part by part

Internal casing and panels

Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.

Drain trays

Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

What we are called out for in Windmill Hill

It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Windmill Hill, that’s air they breathe for hours at a time.

Most sites get in touch when they notice something like this:

  • Air handling units never cleaned inside
  • Dust built up on fan impellers
  • Debris and leaves in the fresh air intake
  • Condensate trays that won’t empty

Classrooms and halls at schools such as Baynards Primary School are easiest to work in when pupils are away.

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too in Windmill Hill and across Essex. Work can be phased by floor, building or site around the people who use them.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

Why act early in Windmill Hill

A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. In a small place like Windmill Hill, a system that fails can take a site out of use.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

What staff can safely do

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

Questions from Windmill Hill

Do you do school ventilation cleaning in Windmill Hill in the summer holidays?

Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Windmill Hill. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Do you cover smaller places like Windmill Hill?

Yes. Windmill Hill is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Does the AHU have to be shut down for cleaning?

Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.

What do you do to protect the area?

We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.

What happens if you can’t reach some of it?

We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

What information do you need?

Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711, or send details by email.

Do you repair air handling units?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.

What’s included in an AHU clean?

Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
