About our AHU cleaning in Earls Colne
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you are dealing with dirty fans and fan housings and intake sections clogged with outdoor debris, we can help, from filter sections, internal panels and drain trays onwards.
In a smaller place like Earls Colne, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Each visit ends with a written report and pictures, 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 AHU cleaning can’t fix
Before you book, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Internal panels
- Filter sections
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
Aftercare tips
Once we have finished, these simple steps help:
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
- Change filters on schedule and log each change
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why deal with it now?
Standing water in a drain tray does not 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. When a site near Earls Colne shuts unexpectedly, the people who rely on it notice at once.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Common questions in Earls Colne
Can ventilation in schools around Earls Colne be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Earls Colne. Just call us on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Do you work in villages like Earls Colne?
Yes, we work in villages as well as towns, and Earls Colne is covered. Let us know about access, parking and anything unusual about getting there when you book.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
When to call us in Earls Colne
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
These are the problems we see most often:
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
Wherever a school like Earls Colne Primary School and Nursery has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
