About our AHU cleaning in Shorthampton
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for rooms that smell stuffy when the system runs and units needing a clean before a new tenant or handover, across dampers and louvres, supply and extract fans and drain trays.
Somewhere as small as Shorthampton, 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 dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send pictures, we can arrive in Shorthampton knowing what to expect.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading

Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.
Related advice
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- The times the site is available
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
Helping us quote
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings

Do you work overnight in Shorthampton?
Yes, nights and weekends are routine for us. That way a site in Shorthampton doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.

What else we do in Shorthampton
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
If you’re not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer before you book.
