AHU Cleaning in Darland
Our technicians work in Darland on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports as standard.
- Air handling units due a clean after building work
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
Staff cleaning versus specialist work
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.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
AHU cleaning in Darland
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. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, drain trays and supply and extract fans, and common reasons people get in touch are intake sections clogged with outdoor debris and dirty filters cutting the airflow.
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.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Between visits
So the system stays in good health:
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Flag stale or damp smells in the supply air
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Why act early in Darland
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. In a small place like Darland, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the system
- Whether we need access equipment or extra panels
- The condition of the system
- Any permits to work or inductions
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
For a fixed quote, call 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

Signs you need AHU cleaning in Darland
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
What we’re most often called out for:
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
Healthcare buildings such as Medway Maritime Hospital, about 1.4 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Darland, yours matters too.

- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
- Whether they recommend a next date
- When they can work, and whether that’s outside your opening hours
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Darland and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Move anything stored near the system
- Have your last certificate or report to hand
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
