Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
AHU cleaning in Keeres Green
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. 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 drain trays, and the jobs we see most are air handling units with blocked filters and fan sections that haven’t been cleaned in years.
In a village or hamlet like Keeres Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Rural roads and tight entrances are worth telling us about before a visit to Keeres Green.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use

Keeres Green buildings and their air
Food Standards Agency records list about 3 schools, colleges and universities registered as food businesses within roughly a mile and a half of the centre of Keeres Green. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 27 miles out from central London, Keeres Green is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
Wherever a school like Rodings Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- Store the TR19 paperwork where auditors can find it
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
When it’s something else
Some problems need a different service or another trade:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before you book.

Signs you need AHU cleaning in Keeres Green
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Leaves and litter drawn into the unit
- Condensate trays that won’t empty
- Coils clogged with dust and debris
- Stale or musty smells from the ventilation
Ventilation work in and around Keeres Green is risk-based: inspect, then clean what needs it.
Before you book anyone
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system can’t be accessed
- Whether the quote is based on a survey or photos
- Whether the whole system is included, or only the parts that are easy to reach
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
