How we handle AHU cleaning in East Horsley
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with dirty filters cutting the airflow and plant that has been serviced but not cleaned, we can help, from dampers and louvres, drain trays and filter sections onwards.
In a place like East Horsley, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
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.

Your questions about AHU cleaning in East Horsley
Can you clean school ventilation in East Horsley during the holidays?
Yes, and it’s the easiest time to do it. With about 6 schools and colleges on the FSA’s register within roughly a mile and a half of East Horsley, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you come out to East Horsley?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.

What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
- A system that’s undersized for the building
If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
What the work covers
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Drain trays
- Internal panels
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. Cleaning restores the open path through the fins.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.

What else we do in East Horsley
When to call us in East Horsley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
The symptoms we are asked about most include:
- Dirty coils holding back the airflow
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
If you run an office near Horsley station, its supply ductwork can gather dust for years before anyone looks inside.
What to look for in a quote
- How they set the interval to the next visit
- Whether VAT is included
- What happens if part of the system can’t be accessed
- Whether the whole system is included, or only the parts that are easy to reach
What your team can do, and what needs us
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. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
