Managing agents and facilities teams in Trolliloes

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
AHU cleaning in Trolliloes, done properly
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. The work covers dampers and louvres, internal panels and supply and extract fans, and the jobs we see most are air handling units with blocked filters and intake sections clogged with outdoor debris.
Somewhere as small as Trolliloes, 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.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
AHU cleaning in Trolliloes: local notes
About 44 miles out from central London, Trolliloes is part of the South East area we work across. The visit is fixed around your opening hours, not ours. Trolliloes’s nearest hospital, Hellingly Hospital, is about 2.8 miles south-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run a surgery, dental practice or care home near Trolliloes, clean ventilation matters as much to you as to a hospital like Hellingly Hospital (about 2.8 miles south-west). An inspection comes first for any ventilation job around Trolliloes, so the cleaning matches what’s there.

The process
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes one overnight shift for many single units, with bigger plant phased. We agree a date with you, plan the drive to Trolliloes and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
Preparing for the visit
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
- Report musty smells from the vents straight away
- Note any water around the unit or leaks below it
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.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What a clean won’t put right
To be straight with you, some problems need a different fix:
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think before you book.
Parts of the system we cover
- Internal panels
- Supply and extract fans

Why act early in Trolliloes
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. A planned visit to Trolliloes is easier to arrange than an emergency callout.
