How we handle AHU cleaning in Hundred Acres
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and people most often call us about air handling units never cleaned inside and filters that are clogged or overdue.
Work in a small place like Hundred Acres starts with agreeing access and timings.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Hundred Acres, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend

Advice
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Report water on the plant room floor
- Make sure condensate is draining away
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

Do you work in villages like Hundred Acres?

Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can you quote from photos?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How long does an AHU clean take?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
