How AHU cleaning works in Kent

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 supply and extract fans, dampers and louvres and filter sections, and the jobs we see most are intake sections clogged with outdoor debris and dirty fans and fan housings.

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them.

First we agree when the unit can be switched off, including evenings or weekends.
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.
After pictures are taken and the certificate issued.

AHU cleaning around Kent

Buildings across Kent range from large sites with several air handling units to small units in a roof space. Filters, coils, drain trays and ducts all need attention, whatever the size.

We work across London and the South East, and Kent is part of that area. Every job is surveyed first and quoted at a fixed price, wherever it is in Kent. Along the coast in Kent, many hotels, pubs and cafés are at their busiest in the summer, so it pays to book work around the busy season.

Maidstone: Workplaces around Maidstone West station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Wherever a school like South Borough Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What AHU cleaning cannot fix

It’s worth knowing the limits before booking:

Building management system faults
Breakdowns that need a mechanical engineer
Airflow problems caused by the system’s design

Staff cleaning versus specialist work

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Different parts, different methods

Filters

What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.

Rooftop and plant room units

Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.

Looking after it afterwards

To keep the system working properly between visits:

Make sure condensate is draining away
Keep filter changes on time and recorded
Diary the inspection date recommended in the report
Watch for drips or damp patches near the plant

Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.

Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

Leave it or put it right?

If people in a building in Kent complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom.

Your questions about AHU cleaning in Kent

What should I send you?

Some pictures and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.

How long does an AHU clean take?

Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.

Will the ventilation be off while you clean?

Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.

Will we get paperwork for the AHU clean?

Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.

Do you work evenings or weekends?

Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.

How often should an air handling unit be cleaned?

That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.

Is there a survey before the work?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
