- Air handling units with blocked filters

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A few pictures of the system help us make the most of a visit to a place like Roser's Cross.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use

About our AHU cleaning in Roser's Cross
Our AHU cleaning covers sites in Roser's Cross and the rest of East Sussex, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you’re dealing with debris and leaves in the fresh air intake and condensate trays that won’t empty, we can put it right, from filter sections, heating and cooling coils and supply and extract fans onwards.
Somewhere as small as Roser's Cross, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
How the job changes from site to site
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
What we are called out for in Roser's Cross
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
What we are most often called out for:
- Fan sections that haven’t been cleaned in years
- Units that have only ever had filter changes
- Air handling units due a clean after building work
- Odours coming through the supply air
Healthcare buildings such as Uckfield Community Hospital, about 4.3 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Roser's Cross, yours matters too.

Keeping the system healthy
So the system stays in good health:
- Report musty smells from the vents straight away
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
- Plan the next inspection before the last report gets filed away
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
