How we handle AHU cleaning in Loyter's Green
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers filter sections, dampers and louvres and supply and extract fans, and the jobs we see most are air handling units with blocked filters and air handling units due a clean after building work.
For a building in or near Loyter's Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What happens on the day
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. Pictures of the system and its access let us plan the work in Loyter's Green before we set off.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- 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
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work

Why act early in Loyter's Green
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. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like Loyter's Green affects everyone who depends on it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why book with us
- One number for every site across the South East and London
- Ventilation hygiene specialists since 2009
- Accredited under CHAS and SafeContractor, with ISO 9001
- A fixed price before any work starts

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
- Make sure the unit’s access doors open easily
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Your questions about AHU cleaning in Loyter's Green
Do you offer AHU cleaning in Loyter's Green?
Yes, Loyter's Green is within the area we cover across London and the South East. Get in touch with the details and we’ll arrange a survey.
Can you come to Loyter's Green after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
How long will the unit be out of action?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What we are called out for in Loyter's Green
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Loyter's Green, that is air they breathe for hours at a time.
Clients typically contact us after spotting one of these:
- Debris and leaves in the fresh air intake
- Fan sections that haven’t been cleaned in years
- Units needing a clean before a new tenant or handover
- Air handling units with blocked filters
Healthcare ventilation, from large hospitals like Princess Alexandra Hospital (about 4.6 miles west) to small clinics, depends on clean filters, coils and ducts.

Part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
