AHU cleaning in Mongewell
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you have air handling units with blocked filters and leaves and litter drawn into the unit, we can put it right.
In a village or hamlet like Mongewell, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Mongewell simpler. Equipment tucked in a roof space or outbuilding near Mongewell rarely gets looked at unless someone books it.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.

Between visits
Good habits slow the build-up between visits. A few tips:
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
- Look at the condensate drain whenever the unit is serviced
- Report musty smells from the vents right away
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.

What else we do in Mongewell
When to call us in Mongewell
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Look out for any of the following:
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
Classrooms and halls at schools such as Crowmarsh Gifford Church of England School are easiest to work in when pupils are away.

Mongewell questions
Is Mongewell within the area you cover?
Yes. Mongewell is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you clean school ventilation in Mongewell in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Mongewell. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we will fit the work in.
Do you have insurance?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Mongewell, tell us about narrow lanes, gates and parking when you book.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
