What we do, step by step
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. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. A few photos of the system help us make the most of a visit to a place like Hungerford.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us where we can park and unload
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time

How we handle AHU cleaning in Hungerford
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. We’re often asked to deal with fan sections that haven’t been cleaned in years and leaves and litter drawn into the unit, on internal panels, filter sections and supply and extract fans.
Somewhere as small as Hungerford, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What happens if it’s left?
If people in a building in Hungerford complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. A fault that closes a site in a village like Hungerford affects everyone who depends on it.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What we’re called out for in Hungerford
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
The symptoms we are asked about most are:
- Air handling units due a clean after building work
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Leaves and litter drawn into the unit
Wherever a school like Waltham St Lawrence Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before booking anyone
- Whether inaccessible sections are listed on the report
- What hours they’ll be on site
- When the next visit should be, and why
- Whether a survey comes first
Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Stick to the filter change plan
- Book the next check in line with the report
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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.
