- Drain trays holding standing water
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
Between visits
How long the results last depends on use and care. We suggest:
- Stick to the filter change plan
- Report musty smells from the vents right away
- Book the next check in line with the report
- Watch for drips or damp patches near the plant
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
How we handle AHU cleaning in Felcourt
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Common call-outs are for blocked condensate drains and slimy trays and coils clogged with dust and debris, on filter sections, dampers and louvres and internal panels.
Somewhere as small as Felcourt, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Felcourt questions
Can a school’s ventilation in Felcourt be done out of term time?
Yes, holiday work suits schools best. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Felcourt. You can call 0345 646 2711, or email photos with the dates the site is empty.
Do you cover smaller places like Felcourt?
Yes. Felcourt is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Do you need AHU cleaning in Felcourt?
Whatever surrounds a building in Felcourt, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Any of these means the system needs a check-up:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Queen Victoria Hospital (about 1.9 miles south-east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Whether the quote is based on a survey or photos
- How areas they cannot reach will be recorded
- Whether VAT is included
- Whether they’re fully insured
How the visit works
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. All told, the work takes one overnight shift for many single units, with bigger plant phased. If you can send pictures, we can arrive in Felcourt knowing what to expect.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.
Related advice
Why act early in Felcourt
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Systems in rural buildings are often out of sight and out of mind.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
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, next to our reports.

Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Felcourt’s nearest hospital, Queen Victoria Hospital, is about 1.9 miles south-east.
