AHU cleaning in The Heath
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have air handling units with blocked filters and drain trays holding standing water, we can put it right, from filter sections, internal panels and supply and extract fans onwards.
Work in a small place like The Heath starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What else we do in The Heath
What affects the quote in The Heath
You will get a fixed price before we start. It’s based on:
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- What state the system is in
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
The Heath buildings and their air
About 5.1 miles north-west of The Heath is Keech Hospice Care, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 29 miles out from central London, The Heath is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
School buildings such as Breachwood Green Junior Mixed and Infant School are normally done in the holidays, so classrooms are not disturbed. Healthcare ventilation, from large hospitals like Keech Hospice Care (about 5.1 miles north-west) to small clinics, depends on clean filters, coils and ducts.
The Heath is in Hertfordshire. Sites in The Heath get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. The Heath is one of 381 towns, villages and districts in Hertfordshire where we work for commercial clients. There’s also a page for Milton Keynes, about 21 miles away.
All of SG4 is within our area for AHU cleaning, from busy streets to back roads. Whether your site is on Windmill Road, Millway and Brownings Lane or a nearby road, we can help.

Questions from The Heath
Can you work in The Heath outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in The Heath does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Is The Heath within the area you cover?
Yes. The Heath 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.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How long will the unit be out of action?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Why deal with it now?
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. If the system at a site near The Heath fails, there may be nowhere nearby to move to.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.

- Fully insured
- One contact for all your sites in London and the South East

How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like The Heath, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards
