- Leaves and litter drawn into the unit
- Condensate trays that won’t empty

How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Kings Worthy.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.

AHU cleaning in Kings Worthy
We clean air handling units for buildings in Kings Worthy and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have air handling units never cleaned inside and dust-coated heating and cooling coils, we can help, from filter sections, supply and extract fans and heating and cooling coils onwards.
Somewhere as small as Kings Worthy, ducted ventilation is normally 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.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What else we do in Kings Worthy
What we’re called out for in Kings Worthy
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Kings Worthy, that is air they breathe for hours at a time.
Clients usually contact us after spotting one of these:
- Leaves and litter drawn into the unit
- Plant that needs cleaning after a refit
- Stale or musty smells from the ventilation
- Plant that has been serviced but not cleaned
Healthcare buildings such as St John's Rooms And Chapel, about 2 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Kings Worthy, yours matters too.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Work can be phased by floor, building or site to keep disruption down.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.

Questions from Kings Worthy
Can the work in Kings Worthy be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Is Kings Worthy within the area you cover?
Yes. Kings Worthy is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
How much does AHU cleaning cost in Kings Worthy?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will normally reply within one working day.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
When should our AHU next 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.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
