About our AHU cleaning in Stedham
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. The work covers dampers and louvres, internal panels and drain trays, and common reasons people get in touch are dirty coils holding back the airflow and drain trays holding standing water.
Work in a small place like Stedham starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Do you need AHU cleaning in Stedham?
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Common reasons sites call us include:
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
Wherever a school like Stedham Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Landlords, agents and facilities managers
If you look after several sites, 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.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Between visits
How long the results last depends on use and care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Store the TR19 paperwork where auditors can find it
- Clear leaves and litter away from the intake
- Make sure the unit’s access doors open easily
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.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.

Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Stedham, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
